Installing Leakage Switches and Air Switches Issue 5

According to the specification: the power supply is connected to the total open (empty open), (all) up and down, (facing the switch) left zero right fire, and the lighting live wire is connected to a circuit breaker; The socket live wire is connected to another circuit breaker, and then connected to the leakage protection pile (the left is connected to the total open zero line, and the right is connected to the circuit breaker under the live wire), and the leakage is the socket power supply (only for handheld electrical sockets, air conditioning sockets do not have this requirement). Air conditioner, you can add another circuit breaker.

But from the ** point of view, your leakage seems to be the linkage of the total leakage (that is, the leakage action directly drives the total open tripping, which is outdated, because when the handheld electrical appliances leak, the whole room is blackout, even the air conditioning lighting is cut off, a dark), you can separate the total opening and leakage protection, and install it to the rear, that is, the total opening, air conditioning circuit breaker, lighting circuit breaker, socket circuit breaker, leakage insurance. Wire diameter: air conditioner 4 6, lighting bus 4 branches, socket bus 4 branches.

Install the leakage switch before the air switch.

First connect the leakage protector, and then open in the air, the switch is in, the lower is the leakage upper termination of the main line, the lower end out of the two empty open upper end, the lower end of the load.

Generally, it is divided into sockets and lighting under the air switch (a total), the socket is connected to the leakage switch, and the lighting is connected to the 1p.

You don't seem to have enough space in your electrical box.

Then connect it together, the problem is that it is not easy to change the leakage switch and fail the power (there is usually a gate in the meter box, which is more troublesome).

The power supply inlet line is first connected to the air switch on the pile head, and the outlet line of the lower pile head is connected to the upper pile head to ensure that the upper pile head is leaked to ensure that the lower pile head is connected to the electrical appliances. (It is best to install shunt switches for light wires and sockets.)

Connect the leakage protector first, and then open it in the air.

The switch is in and out.

The upper end of the leakage is connected to the main line, and the lower end comes out with two empty connections to open the upper end, and the lower end is connected to the load.

The respective functions of the air switch and the leakage switch: the function of the air switch itself is to open and break the circuit, and then it also has at least two protection functions, namely short-circuit protection and overload protection, and there is also an optional function is under-voltage protection; The leakage switch also has an on-off effect, and the width is an important factor that must be considered in the design of the distribution box - the width of the box determines the size of the wall opening. It's not just about aesthetics, it's about building structure.

The width of the distribution box is determined by the width of the circuit breaker in the distribution box.

When the human body touches these parts, an electric current flows through the human body to the earth. At this time, the zero-sequence current transformer in the leakage circuit breaker will detect the existence of residual current, and after the residual current reaches the action value, the residual current relay will act to trip the circuit breaker. In turn, the current flowing through the body is disconnected.

It plays the role of leakage protection. The leakage protection is based on the chip, generally the chip will be after a main pair of windings, once the main winding is put here to sound a leakage accident, the secondary winding will produce voltage to push the built-in mechanism, and then produce the effect of tripping.

In fact, the leakage switch is composed of an air switch and a leakage module, as the name suggests, the leakage switch must include the function of the air switch, then many people will have questions, since the leakage switch has the function of the air switch, why not use the leakage switch directly, and also make the air switch out of the leakage switch is to prevent the live wire or neutral line from the rapid induction and trip protection device, such as the circuit of the short circuit to be opened by the air and responsible.

Their working principle is different, the structure is also different, if all the air openings are replaced by leakage protection switches, it will bring a problem that the width of the box of the distribution box will be very wide, which determines the size of the wall opening, which not only affects the aesthetics, but also related to the building structure. The width of the distribution box is determined by the total width of the air circuit breaker in the distribution box, and the air open is also called the circuit breaker, which is a replacement product of the old electric switch, with over-current protection and short-circuit protection function, which can realize the automatic tripping of over-current.

This is to have a double insurance, and if the short-circuit protection does not work accordingly, the air switch can also prevent leakage.

Because the air switch is to prevent a fire from a short circuit, similar to the effect of a fuse, the effect is very large.

Mainly to protect the wiring in the whole house, in order to prevent fire caused by excessive voltage and **, for safety reasons

In fact, this is a double guarantee for the family, which can make our lives happier and safer.

The previous leakage switches did not have short-circuit protection, that is, there was no air switch function. The current leakage switch is a combination of the two, that is, it has the function of leakage protection, and also has the function of overload and short circuit protection. However, there is still a difference between the use of air switches and leakage switches, especially for our household ones.

Commonly used air switches and leakage protectors are shown in the figure below. This is called the air switch, the air switch is mainly to monitor the current in the line, if it exceeds its set value, it will jump away, cut off the circuit, whether the current is due to excessive electrical power, or electric shock or insulation damage, will jump away.

The air switch lacks an important protection function – leakage protection. This point can be made up by the leakage switch - the leakage switch and the air switch are only possible in terms of function, and only possible people will feel the difference, that is, the leakage switch has a leakage protection function. Therefore, in circuits prone to leakage, it is necessary to use leakage switches.

For example, the setting value of the air switch is 32A, which is about 7000 watts, and when the current is exceeded, the air switch will trip to form protection.

It has the functions of overload protection, short circuit protection and leakage protection, and conforms to GB standard. Both circuit breakers are suitable for use in domestic and similar settings, they are designed for use by non-professionals and do not require maintenance. Air switch and leakage protector are necessary for electricity safety in the family, and the two switches can achieve different protection functions, so it is not a question of whether they can be installed at the same time, but must be installed at the same time to ensure the safety of electricity.

Let's explain the two types of switches.

The choice of air switch and leakage protection, many friends are estimated to have been fooled by the decoration team, and tell you that the home is equipped with leakage protection, in fact, it is simply a lie to you, the air switch and leakage protection are selected according to the function we use, and the home miscellaneous altar will give you a good talk about how to install the air switch and leakage protection.

Yes, it can not be installed at the same time, it should be installed at intervals for a period of time, if it is installed together, there may be very bad things, you must pay attention to it when decorating.

These two cannot be installed at the same time, because they affect each other and are easy to induce unsafe accidents, so the air switch should be installed after the leakage switch.

Personal opinion, if there is any error, please correct. The function of the empty opening is: ** There is a short circuit, overload and other situations in the road, and the current is cut off immediately to protect personal safety; The leakage switch has the function of empty opening, and there is an additional leakage protection, which is a protection function for the leakage of lines and electrical appliances.

For household electricity, it is recommended that the main gate be open empty (double horse), the light should be open empty (single horse), and the socket leakage protection (double horse).

Because these two devices are in a contradictory state, but the necessary one can be installed according to the needs of their own home, most people still choose to install air switches.

Leakage switches and air switches are collectively referred to as air switches. The former is protected against leakage, and the latter is not.

Air switches without leakage protection are used for main switches and lighting lines, while air switches with leakage protection are mostly used for socket lines.

The air switch without leakage protection belongs to the overcurrent insurance, that is, the current on the line exceeds the rated value of the air switch and trips instantly, while the air switch with leakage protection can trip in an instant only in the case of zero and live wire current inconsistency, that is, leakage (this value is generally set to 30 mA, that is, the difference). The two cannot be mixed, otherwise, they will not play a protective role.

The wiring method of the leakage switch and the air switch is the same, but the air switch is mainly used to control the main power supply end, as a power outage and power transmission, while the leakage switch is mostly used for sockets when connected to the power supply end.

The air switch can cut off the overload current, which can play the role of overcurrent protection and short-circuit protection. The leakage switch can be leakage protection and can protect personal safety.

Both can be installed at the same time, so as to ensure that our electricity process is safe and secure. Be sure not to install it privately, but let someone who knows how to install it yourself.

Yes, it can be installed at the same time. When the specific operation is carried out, the air is installed first, and then the leakage is installed, so as to ensure that the power can be quickly cut off when the current runs out.

It is not necessary to install the air switch and the leakage switch at the same time. Because of the air switch, it contains all the functions of the leakage switch. As long as we are choosing those that have a brand guarantee, ** more expensive air switches. That's it.

Yes, this operation requires a professional person to operate it to ensure that both devices can be used normally.

The respective functions of the air switch and the leakage switch: the role of the air switch itself is to open and break the circuit, and then it also has at least two protective functions, namely short-circuit protection and overload protection, in addition to the optional function is the sub-switch of each circuit of under-voltage protection, and the lighting circuit switch recommends that you choose the air switch, especially if you use LED lights, you must not use the leakage switch; All the other socket circuit switches are recommended to choose the leakage switch, because the electrical appliances connected to the socket may leak and can be accessed by the human body.

Width is an important factor that must be considered when designing a distribution box – the width of the box determines the size of the wall opening. It's not just about aesthetics, it's about building structure. The width of the distribution box is determined by the width of the circuit breaker in the distribution box.

Generally speaking, the air switch uses air as an insulating medium, and when the current is connected, heat will be generated, which will also make the metal sheet bend upwards when heated, pushing the lever, and the lock that should be buckled will be forced to open, so as to achieve the purpose of cutting off the power supply.

The leakage switch is a device to prevent the live wire or neutral line from tripping protection when it has a rapid induction into the ground, such as a short circuit on the circuit to be responsible for the air on, their working principle is different and the structure is different. The leakage switch is wider than the conventional 1P air opening, if all the air openings are replaced by leakage protection switches, it will bring a problem that the box width of the distribution box will be very wide, which determines the size of the wall opening, which not only affects the aesthetics, but also related to the building structure. The width of the distribution box is determined by the total width of the air open circuit breaker in the distribution box.

Leakage protector, commonly known as leakage switch, is used to prevent personal electric shock and electrical fire when the circuit or electrical insulation is damaged and the ground short circuit occurs, generally installed in the socket circuit of each household distribution box and the power supply line of the main distribution box of the whole building, the latter is dedicated to preventing electrical fire.

To be installed, this double protection avoids people from being harmed, and also greatly protects people's electricity safety.

To install an air switch, it is also to better solve the problem of leakage and better protect the safety of people.

I think that if the leakage switch has short-circuit protection, we still need to install an air switch, because this way there is an additional option, which can be more convenient.

It is still very helpful to live if you need to install an air switch, and it will become particularly inconvenient in daily life if you do not install an air switch.

In the process of every house decoration, there will be a lot of various switches that need to be installed, and for those switches, each one has its own function, if the installation is wrong, it will affect our normal life. Therefore, it is necessary to know more about this aspect when decorating. Who installs the air switch or leakage switch first?

Generally, the air opening is installed first, and the power supply of the air switch is connected first, because the air opening needs to be used on the main switch of the ** road. The leakage switch is used on the branch switch, and these two are installed at the same time, and the leakage switch is installed behind the empty opening. If the leakage switch is installed in the front, it is easy to skip the trip once the leakage is leaked.

How the air switch works.

When using electrical appliances, the circuit is overloaded too much, which will cause the components to generate heat, and when the heat of the metal sheet reaches a certain level, it will bounce upward, at this time the lever and lock will be pushed away, and then it is the operation of cutting off the power supply. If the overload of the line is very serious, the current exceeds the instantaneous, there will be a large enough suction force to hit the lever, and the lock will contact the three main main disconnects under the influence of the reaction spring, and the power supply will be cut off.

The working principle of the leakage switch.

The inside of the leakage switch is composed of two combined current windings, one is the input and the other is the output, when there is no leakage under normal circumstances, the current generated by the two of them is equal, at this time there will be no third winding will induce potential, if the third winding will induce voltage, then the switch will trip directly.

After we understand the working principle of the air switch and the leakage switch, we can better choose the two switches, and it is recommended that both switches are installed in the home decoration, so that there can be double protection.

Summary: The above is an introduction to the installation sequence of air switch and leakage switch, I believe it will be of great help to you. I also know a lot about the working principle of air switch and leakage switch, and I will be more handy when choosing.
