Why do air conditioner manufacturers require the installation of leakage protection switches?

Because air conditioners have relatively large requirements for electricity, especially when we need refrigerationIt will be humid for a long time, so it is necessary to add leakage protection to prevent accidents.

It is important to note that the protected line and the adjacent branch line have their own neutral line。Household leakage protectors.

The neutral line on the load side cannot be shared with other electrical equipment circuits, otherwise the leakage protector cannot be supplied. The wiring must be correct, and the household leakage protector marked with the power supply and the load cannot be reversed.

We must strictly distinguish between the neutral line and the grounding protection line PE. The neutral wire must be connected to the leakage protector, PE wire.

We know that i1 = i2 + i3, which flows through the zero sequence current transformer inside the leakage protector.

The current is IL≠in, and the zero-sequence current transformer has a trip signal output. This has something in common with the use of neutral wires with other circuit neutrals. This is the main reason why many users in the power supply transformation of our residential area mentioned at the beginning of this article cannot transmit electricity normally.

For the common unipolar household leakage protectors on the market today,Phase wires.

l must enter the switch k, l line and n line shall not be connected by mistake, otherwise, when the leakage current.

When the power supply needs to be disconnected, the leakage protector cannot disconnect the power supply normally, resulting in a more serious electric shock accident. Therefore, we must pay attention to the electricity at home, do not connect it randomly, and pay more attention to the children at home and do not let him play with electricity to prevent accidents.

Over time, it is easy to get wet. In order to prevent accidents, leakage protection must be required.

Because in today's life, the power consumption rate of air conditioning is still relatively large.

Because air conditioners have relatively large requirements for electricity, especially when we need refrigeration

Because it prevents the air conditioner from leaking, it plays a protective role and is safer.

Because the air conditioner has a large demand for electricity, the wiring must be correct, and the household leakage protector marked with the power supply and the load cannot be reversed.

Summary. Hello, I am glad to answer for you if it is a 2P cabinet air conditioner, it must be installed, because the instantaneous current of the air conditioner is relatively large, the fan turbine and control devices are in the cabinet, the air conditioner will produce condensation after working for a little time, and the "fog" blown out will cause the insulation to decline, there are many "special sockets" on the market and there is no reliable grounding wire or the copper plate is too thin to cause the "hot melt" phenomenon, some general distribution boxes are equipped with leakage protector thresholds that are too large (60A or higher), for the sake of safety, Cabinet air conditioners need to install air conditioner leakage protection switches.

Does the air conditioner need to be equipped with a leakage protector?

Hello, I am inquiring for you, please wait a while, I will reply to you immediately Hello, I am happy to answer for you If it is a 2P cabinet air conditioner, it must be installed, because the instantaneous current of the air conditioner is relatively large, the fan turbine and control devices are in the cabinet, the air conditioner will produce condensation after working for a while, and the "fog" blown out will cause the insulation to decline, and there are many "special sockets" on the market and there is no reliable grounding wire or the copper plate is too thin to cause the "hot melt" phenomenon, Some main distribution boxes are equipped with leakage protector thresholds that are too large (60A or higher), for safety reasons, cabinet air conditioners need to install air conditioner leakage protection switches.

I hope the above will help you If you are satisfied with me, please give a thumbs up Hanging type, refrigeration capacity 3500w, do you need it?

Dear, can you do without, can the latch of the air conditioner be plugged into the plug converter?

Pro, you can also, the daily household electricity is not needed.

Dear, is it okay to give a like?

Because the shell of the air conditioner is grounded, when leakage occurs, the ground wire can reduce the leakage voltage of the air conditioner. Because the resistance of the ground wire is very small, the resistance of the person is large, so the person will not be electrocuted. This ground wire is called the protective neutral wire (also called the protective ground.

These two kinds of words depend on what kind of power supply system is built on the grid), so this line is very important.

It is not that the air conditioner cannot be connected to the leakage protector, and there is no need to install a leakage protection switch separately.

The air conditioner is not unable to be connected to the leakage protection, it is not necessary to install a leakage protection switch separately, and now every household has installed a leakage protection switch on the meter. If the main power supply of the household is equipped with leakage protection function, the power supply branch of the air conditioner can not add leakage protection switch, but only use the ordinary air open.

Significance of Leakage Protector:

1. Leakage protector, referred to as leakage switch, also known as leakage circuit breaker, is mainly used to protect the equipment from electric shock when leakage fault occurs and to protect people with fatal danger, with overload and short-circuit protection functions, which can be used to protect the overload and short circuit of the line or electric crack vertical motor, and can also be used as an infrequent conversion and start of the line under normal circumstances.

2. The leakage protector is a device that automatically cuts off the power supply to protect life when the human body is electrocuted or electrical leakage.

3. When leakage occurs, when the leakage current is greater than (generally 30mA is the human safety current), the switch will jump off and cut off the power to prevent people from being electrocuted due to short circuit of the circuit and prevent electric shock.

4. The principle is to pass the neutral line and the live wire through the transformer inside the leakage protector at the same time, and the transformer can only detect the current of a single AC wire, and the transformer can not feel the current when the current of the zero source difference line and the phase line is the same.

5. When the leakage is not the same as the phase line current, the transformer feels the current and sends a signal, and the amplifier amplifies the signal to the electromagnet inside the leakage protector after amplifying the signal, and the tripper falls down after the electromagnet acts, and opens the gate to play a protective role. <>

Because the shell of the air conditioner is grounded, when leakage occurs, the ground wire can reduce the leakage voltage of the air conditioner. Because the resistance of the ground wire is very small, the resistance of the person is large, so the person will not be electrocuted. This ground wire is called the protective neutral line (also called the protective ground, these two words are specifically determined according to what kind of power supply system the grid is), so this wire is very important.

Leakage protection switches are commonly used in the following categories according to their functions:

1) It only has the function of leakage protection and power-off, and must be used with fuses, thermal relays, overcurrent relays and other protection components.

2) At the same time, it has the function of overload protection.

3) At the same time, it has the function of overload and short circuit protection.

4) At the same time, it has the function of short circuit protection.

5) At the same time, it has the functions of short circuit, overload, leakage, overvoltage and undervoltage.

Because the air conditioning lighting is far away from the contact surface of the human body, it is basically out of reach, and it is the best.

The leakage protector can be installed on the total inlet line, and there is no need to install it separately

Ceiling lights and wall-mounted air conditioners can not be pressed leakage protectors, floor lamps and metal shell lamps and lanterns should be installed with lighting leakage protectors (air open starts with the word C), cabinet air conditioners should be installed with power leakage protectors (air open starts with the word D).

Your main gate is installed with leakage protection, and the others can not be pressed. The difference is that if there is a leakage, the main gate will be tripped, and if it is installed on the branch road, the gate of the road where the jump is located will not affect the others.

There is almost no chance of electricity leakage from air conditioners and lighting.

The air conditioner needs a leakage protection switch, an air switch, and the heating power of the three-horse air conditioner is about 2800 watts, plus the auxiliary electric heating power is 2000 watts, a total of 4800 watts, and the current is about 22A. It is recommended to use a 32A air switch, preferably an air switch with leakage protection.

A 1 hp waste air conditioner** can be worth about 200 yuan. When it comes to low-rise and low-difficulty high-altitude work, the waste air conditioner can be worth about 150; Low-rise and high-difficulty high-altitude work, waste air conditioner can be worth about 100 yuan. High-rise and low-difficulty high-altitude work, waste air conditioner ** can be worth about 80 yuan; High-rise and difficult high-altitude work, waste air conditioning** is generally used to replace the operation cost with air conditioning.

Air conditioning** status.

According to statistics, the annual scrapping of household appliances exceeds 50 million units, with an average annual growth rate of 20%.

Although there are many factors that affect the supply of goods from formal dismantling enterprises, to be precise, the amount of slag collected is not a problem, the problem is the recycling of renewable resources, and environmental protection issues.

Especially now, many unqualified mobile vendors just use simple tools to disassemble electrical appliances, because of the backward processing methods, so only iron, copper and other parts that are easy to use, and some valuable resources such as gold and silver can not be fully utilized, resulting in a waste of resources.
