The correct way to change the circuit, and what problems should be paid attention to when changing t

1. Install the pipeline first and then thread the wire.

In the installation, the pipeline should be installed before the wire is threaded. After the wire is loaded into the casing, the wire should be fixed with a clamp, which should be fixed in the wall and the wall first, and then plastered to conceal or conceal it with baseboards and decorative corners. The installation of the socket box should first open a hole in the wall, after the wire is inserted into the wire box, the wire box is fixed in the hole, the wire is fixed with the panel, and the panel is fixed on the box.

The method of installing the power switch is the same as that of the socket box.

2. Bending treatment and dark compress.

It should be noted that different lines cannot follow the same pipeline. If the TV antenna, the first line and the distribution line are penetrated into the same line of pipes, so that the reception of the TV and the first line is interfered with, it will inevitably affect the use of these equipment. TV antenna lines and ** lines must be separately threaded separately.

Special attention should be paid to the position of the bend when bending, and it should be treated with a dark compress.

3. There is no kink in the wires in the pipe.

The number of wires in the same tube cannot exceed four, if more than four, it will affect the normal operation of the circuit in the home. The wires should be fixed, not pulled freely, and the insulating tape should also be used properly, and it is absolutely not advisable to connect the decoration wires with "convenient black tape". If you want to be safe in the future, throw the black tape out.

These problems are easy to be ignored, in order to avoid problems in the circuit renovation project, the decoration owners must first pay attention to it psychologically, and then strictly supervise it in the process of circuit transformation, find that the electrician does not do well, and remind the electrician to improve in time to ensure that the home improvement project is carried out smoothly.

4. Accurate configuration of electrical wiring.

The circuit design should be multi-channel, so that the air conditioner, kitchen, bathroom, living room, bedroom, computer and high-power electrical appliances are wired separately; Sockets and switches are separated, and leakage protectors should be used independently in each circuit except for general lighting and wall-mounted air conditioners; Strong and weak are separated, and the design of weak current lines such as audio, multi-current, and broadband networks should be reasonable and standardized. For air conditioning, lighting, and sockets, they should be controlled by separate circuits, generally at least four circuits. Lighting goes all the way, air conditioning goes all the way, and sockets go three to four ways.

The advantage of this is that once a short circuit or other problem occurs in one line, the scope of the power outage is small and will not affect the normal operation of several other lines.

5. Pay attention to the spacing between strong and weak electricity.

The spacing of the junction box of the strong and weak wires is 500mm under normal circumstances, and the parallel spacing on the ground is not less than 200mm. Such a distance is the most effective way to isolate the electronic waves and reduce the harm to people. Water.

First, the slotting method.

Whether it's a wire or something else, if it's left in a bent state for a long time, it may break. When the road is slotted, we can design it as an oblique groove when there is a 90-degree bend to ensure that the wire can still be retracted and released freely after a few years!

Second, the depth of slotting.

Of course, line slotting, in addition to the method, depth is also an intriguing problem, it will directly affect the cracking of wall cement powder, and in order to avoid such a situation, generally speaking, the depth of our line slotting is also standard, 16 pipe slotting depth is not less than 30mm; 20. The groove depth of the tube is not less than 35mm; The thickness of cement mortar is not less than 15mm.

Third, the width of the slot.

In order to ensure that the wall surface of the open line will not crack, the slotting width of the single line pipe is not less than 30mm, and the slotting width of the double line pipe is not less than 60mm. In this way, it can be ensured that there is enough space between the line pipe and the trunking to fill the cement river sand.

Fourth, line pipe joints.

Generally speaking, the connection between the wire box and the wire pipe needs to be connected with a lock to ensure its stability, on the other hand, the lock has a certain flame retardancy, even if there is an accident, it can also ensure the safety of the circuit.

Fifth, about the pipe card.

The distance between the pipe clamps should not exceed 800mm, and the distance from the bend point to the fixed place of the pipe clamp should be kept within 200mm. It is important to ensure that the conduit is stable when it is secured, so that even if the wiring needs to be overhauled in the future, the conduit will not loosen when the wire is twitched.

6. Reserve the thread.

A section of wire is usually reserved on the ceiling for use when installing chandeliers. The length of the wire is generally not less than 50cm, so as to avoid the situation that the length is not enough during installation. It is necessary to roll the reserved wire into a spring-like shape and add a spring plastic shell to fix the ** slot inside to avoid the end of the wire from falling down, so as to ensure the safety of electricity.

It is recommended to find a master to change, and the first precaution for circuit transformation: a principle, that is, do not use too much power strip. However, in the location where the electrical plugs are more concentrated, you can consider connecting a plug-in board in the future, which is often simpler than setting up many sockets on the wall, and it is easy to move the position.

Precautions for decoration circuit renovation 2: The bedroom lights are best dual-controlled, respectively located at the entrance and the bedside. That way you don't need to go dark to turn off the lights.

Precautions for decoration circuit transformation: The circuit switch in the room should be controlled more and easier to use.

Precautions for decoration circuit transformation: strong and weak wires cannot be in the same pipe, there will be interference.

When we are decorating the house, we will definitely decorate water and electricity, because now people's lives are becoming more and more technological, there is no way to live without electricity, and there is no way to live without water, decoration electricity, there must beHome renovation circuit design diagram, then you knowHome renovation circuit design diagramHow to design? If you don't know, let us introduce it to you!

1. Home decoration circuit design diagram.

1.Single-loop wiring per room. This method is often used in the old house, the characteristics are more line-saving, labor-saving, the disadvantage is that there are high-power and low-power electrical appliances in a room at the same time, then the air switch must be configured according to the power of high-power electrical appliances, so that it is easy to make the current in the wire in a high-load state for a long time, and it is easy to cause the main line to age faster.

2.The ground and the top surface are still very different, the top surface try to take shortcuts, save wires, of course, they are all straight lines, because the straight line is always the shortest distance, the ground is as vertical as possible, and walk along the wall, mainly convenient for maintenance, reduce crossing, ensure safety, and avoid later construction, such as the installation of the floor to cause accidental damage to the wires.

2. Precautions for circuit transformation.

1.After the circuit is planned, it is necessary to groove the wall and the ground first, and the owners need to communicate with the electrician workers about the specific circuit direction, draw the correct circuit diagram, and then groove the corresponding position of the wall and ground according to the instructions of the circuit diagram. Do not let workers violently slotted at will, in the home, some walls are load-bearing walls, if you slot and bury pipes at will, it will destroy the structure of the entire home.

At the corner of the groove Zhengshi Road, it is necessary to do a good job of fillet treatment cavity mountain to prevent the sharp right angle at the corner from scratching the threading pipe.

2.During the construction of circuit transformation, it should be noted that various strong and weak lines cannot take the same pipeline, otherwise they will interfere with each other. If the TV antenna and the distribution line are threaded into the same conduit, the TV signal will be interfered with to a certain extent, which will inevitably affect the use of the equipment.

Therefore, the TV antenna line, the ** line and the network cable must be separately threaded separately.

3.When we lay the point display, according to the use area, the lighting circuit can be selected two or three ways, and the power socket can be three or four ways. The kitchen and bathroom should each take one route, two or three air conditioning circuits, and one air conditioning circuit with a maximum of two air conditioners.

In this way, when one of the circuits fails, the other circuits can still supply power normally without too much impact on normal life.

Well, the above is a brief introduction to the home decoration circuit design diagram and circuit transformation precautions, so after you read the article, do you know what are the precautions for circuit transformation?

Circuit renovation is a key construction project when home renovation, after we move in, the quality of decoration will have a long-term impact on life. If the circuit is unreasonable and the process of decoration and construction is not standardized, it will not only bring great problems to our lives, but also invisibly bring hidden dangers to the safety of electricity. When renovating the circuit, pay attention to the following precautions to help better the circuit decoration.

When renovating a circuit, after planning the circuit design, the walls and floors must be grooved. First contact the electrician to understand the specific direction of the circuit, and after drawing the circuit diagram, follow the instructions in the circuit diagram to enter the slot. It is important to prevent workers from grooving violently, because some walls are load-bearing walls, and random grooving can destroy the structure of the entire room.

The corners of the channel should also be rounded to prevent the threaded pipe from scratching around the corners.

When the circuit is modified, the wires must pass through the PVC pipe before they can be buried in the wall. Burying it directly in the wall makes it very susceptible to aging and also makes subsequent maintenance difficult.

Some construction equipment needs to place many cables in the PVC pipe to save time and effort when remodeling the circuit, which is very bad behavior. The cables in the pipe must not exceed 40% of the cross-sectional area of the pipe, and in general, it is best to limit the cable to about three cables. Too many cables in a pipe will not only affect the service life of the pipe, but also increase the service life of the pipe.

There is a security risk.

When the circuit is reconstructed, the strong electrical pipe and the weak electrical pipe cannot be located in the same slot. Strong cables cannot penetrate the same pipes as weak cables. Due to the electrification of strong wires, the electromagnetic waves generated will strongly affect the weak electrical signal.

If the strong conduit crosses the weak conduit, the conduit should be wrapped in aluminum foil to intersect the intersection.

If the cable is bent or branched when the circuit is rebuilt, please use professional elbows and sleeves to connect. If the cable is not long enough, connect it to the chassis and make sure that the cable in the threaded pipe is not spliced or twisted, so that the circuit modification is also more safe and reliable. , you can get it for free

In the construction, the process of circuit transformation is more complex, and it is easy to have some potential safety hazards, so the circuit transformation construction process must be carried out in strict accordance with the specifications. It is recommended to find a professional to modify, if you want to modify yourself, you have to be very careful. Today, Yuanpai will take a look at how to transform the circuit and what needs to be paid attention to.

1. Transform the circuit by yourself.

1. First of all, we must locate the circuit according to your use of electricity, such as the requirements of switches, sockets, and lights.

2. After the positioning is completed, according to the positioning and circuit direction, open the wiring groove, the wiring groove is very particular, and it should be horizontal and vertical, however, the standard practice does not allow the transverse groove to be opened, because it will affect the bearing capacity of the wall.

3. The wiring is generally buried in the way of the wire pipe. There are two kinds of line pipes: cold-bent pipe and PVC pipe, cold-bent pipe can be bent without breaking, which is the best choice for wiring, because its corner is curved, and the line can be replaced at any time without opening the wall.

Second, what need to be paid attention to in the transformation of the circuit.

1. The wires of strong and weak current should be laid separately, the minimum spacing is more than 30cm, if the weak wire is buried, the wiring should be horizontal and vertical, and when encountering a turn, a special elbow should also be used, if it is an audio line or a broadband line, there must be no joint; If it is a ** line, the connector of the network cable must use a special connector or distributor.

2. The bottom margin of the switch box is best from the ground, and the side margin is best above 7cm, if it is in the same room, these distances must be consistent; When the switch of the same type is installed in parallel, the height difference between the two and the ground should not be more than 1mm, and the height difference of the switch installed in the whole set of rooms should be greater than 5mm.

Although the amount of circuit modification operation is not very large, the installation must be meticulous, and safety must be paid attention to.

1. Slotting of wires and lines.

After discussing the electrical functions and requirements with the owner, the person in charge of the construction will explain to the electrician and make the parallel and vertical lines slotted. Put away the switch socket bottom box.

The socket class is slotted 40 cm from the ground; The hanging air conditioning socket is slotted from the ground meter; The switch is slotted in meters from the ground.

The bottom of the switch and socket should be slotted with the horizontal line. The kitchen and bathroom must be slotted according to the designed use function.

2. Wiring of wires and circuits.

Material requirements: copper core wire above square meters, wire pipe above 16mm.

Wiring requirements: 1) Most electricians do not consider the strong and weak currents, switches, air conditioning sockets, and electrical sockets separately in the circuit wiring. Therefore, grooving saves a large number of processes.

2) The required wiring of strong and weak current is separated by 30 cm at a minimum; Air conditioning sockets are dedicated to wire groups of more than 6 square meters; 4 square meters of special group for electrical sockets; Switch more than square meters of special grouping.

3) The air conditioning line group is more than 2 meters from the ground. Electrical wiring group ground wiring, switch and lighting wiring group wall top wiring. The switch socket must be installed horizontally and vertically when the bottom is closed, so that the rear panel installation will be more flat.

4) The switch and socket of the kitchen must be arranged and installed according to the function of the kitchen cabinet design. After all the electrical lines are arranged, the person in charge of the construction should remember the layout and discharge size of the lines, so as to facilitate the installation of various home accessories in the later stage.

5) Now there are generally two kinds of PVC pipes: 6 points and 4 points. If possible, use 6 points and indicate it in the budget.

6) A 4-point pipe can only wear lighting wires, and a maximum of 3 wires can be worn in a pipe. 6. Wires that can be threaded through pipes, and a maximum of 3 wires can be threaded in one tube.
