What is the difference between an air switch and a leakage protector?

First, the nature is different.

1. Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects whenever the current in the circuit exceeds the rated current.

2. Leakage protector, referred to as leakage switch, also known as leakage circuit breaker, is mainly used to protect the equipment from leakage failure and personal electric shock protection 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 motor, and can also be used as an infrequent conversion and start of the line under normal circumstances.

Second, the characteristics are different.

1. Air switch is a very important electrical appliance in low-voltage distribution network and power drive system, which integrates control and a variety of protection functions. In addition to completing the contact and breaking circuits, it can also protect the circuit or electrical equipment from short circuits, serious overloads and undervoltages, and can also be used to start the motor infrequently.

2. Leakage protector:

1) When the power grid is indeed grounded, the leakage protector operates normally. In this normal action, due to the aging of the power grid and the change of climate and environment, the actions caused by the grounding point of the power grid account for the vast majority, while the actions caused by personal electrocution are very few.

2) The power grid is not grounded in the first place, but the leakage protector may be misoperated under the following circumstances:

Since the leakage protector is a signal-triggered action, it will also produce a signal-triggered leakage protector action under other electromagnetic interference, resulting in a misoperation. When the power switch is closed and powered, an impact signal will be generated, causing the leakage protector to malfunction. The sum of the leakage currents of multiple branches can cause overstepping misoperation.

Repeated grounding of the neutral wire may cause stream malfunction.

The air switch is a bit better.

It has overload, short-circuit protection, and leakage protection function, which is the first choice for home decoration circuits.

The air switch is generally used for a long time to prevent the circuit from being overloaded, and in order to prevent the human body from being electrocuted, it only plays the role of a fuse. The leakage switch mainly protects the leakage of the circuit and prevents personnel from being electrocuted, and does not play a big role in the overload of the circuit. Therefore, the socket circuit in the home must use an air switch with leakage protection.

Because of the different working principles, the two functions cannot be replaced with each other. However, all of the above, air switches are a better choice than leakage switches.

Air switches and leakage protectors are used in daily life, but they must be used before using them to achieve the effect. Let's introduce to you what is the difference between air switch and leakage protector. What is the difference between air switch and leakage protector 1. The protective function is different, and the air switch is generally suitable for preventing the circuit from being overloaded and preventing the human body from being electrocuted, so it plays the role of a fuse.

The leakage protector is also to prevent electric shock and leakage of the human body, but this circuit will not play a big role when it is too heavy, and it can play a protective role for some small circuits. 2. The way of action detection is different, when the circuit is too heavy and the guide trips, it can be used to protect the safety of electricity. The leakage protector can detect the remaining current, and the purpose is to protect the loop current, which can avoid the leakage value, cut off the leakage protector, and prevent the click that comes into contact with the leakage current.

3. The reason for tripping is different, and the air switch is mainly through the live wire and the neutral line, and if the current between the two wires is relatively large, it will trip. The main reason for the leakage protector is the fire wire, and when it comes into contact with the fire wire and the ground, there will be a family shelter and shout a loop, and the device inside will be automatically touched by Zhaoye, so as to achieve the purpose of tripping and play a protective role. What is an air switchAir switch compared with traditional switches, it can be said to be a kind of control equipment, which can play a protective role in the use of the circuit, and when the electrical equipment is under load, it is more suitable for use in the starting motor.

Summary: What is the difference between the air switch and the leakage protector The relevant content is introduced here, it can be said that there are still many differences between the two, such as different protection effects, different tripping reasons, etc., so you must understand the use clearly when choosing.

There are some similarities in the appearance and function of leakage protection switch and air switch, so some consumers will confuse leakage protector and air switch, so what are the differences between leakage protector and air switch? Next, I will briefly introduce to you what is the difference between leakage protector and air switch.

1. According to Qeeka Home experts, there are differences in appearance and function between leakage protectors and air switches. For example, the leakage protector has a reset switch and a test switch, while the air switch does not. The leakage protection switch is mainly used to protect the safety of the human body, when the electrical appliances and lines leakage, the leakage protection switch will automatically short circuit to prevent electric shock accidents; The air switch mainly protects the circuit and electrical appliances, and will automatically cut off the circuit when the current is overloaded, which can prevent the electrical appliances and circuits from being burned.

2. We usually install leakage protectors and air openings when carrying out interior decoration, although there are some similarities between leakage protectors and air switches in appearance and function, but the two cannot be mixed. When you use the leakage protector, you should press the test button once a month to check whether the leakage protection function of the product is effective. If you press the test button and can't trip, then the leakage protector is abnormal and needs to be repaired and replaced.

3. Leakage protector and air switch are very important household appliances, and we try to choose local well-known brand products when buying air opening and leakage insurance. The more well-known brands in the market include Schneider, Legrand, Bull, Chint, Delixi Electric, Simon Electric and so on. In the case of ensuring product quality, we can compare several products, after-sales service, etc., and try to choose cost-effective products.

Summary: What is the difference between leakage protector and air switch, I will briefly introduce it to you here. I hope that after reading this article, you will be able to understand the difference between leakage and empty opening.

After having a certain understanding of air switches and leakage protectors, let's take a look at the difference between leakage protectors and air switches. First of all, the functions of air switches and leakage protectors are similar, they both have the effect of disconnecting the circuit, but the capacity of the air switch will be larger than that of leakage protection devices. Secondly, the appearance of the air switch and the leakage protection device is very similar, but the leakage protector has one more reset button and test button than the air switch.

In the circuit protection of households, leakage protection devices are often used, when the circuit of our household appliances is damaged is to prevent electric shock when a short circuit occurs, it is installed on the circuit of the user's distribution box, as well as the power line of the main distribution box on the floor of the community. The air switch will trip when there is a short circuit, so as to prevent electric shock and protect electrical appliances and personal safety.

Some friends will think that the functions of air switches and leakage protectors are similar, and they can be used interchangeably. This is not the case, although the leakage protector has one more protection function than the air switch, but we cannot replace the air switch with the leakage protector, because the trip function of the air switch is very important in industrial production, which is not solved by the leakage protector.

The ground protection principle of the air switch and the leakage protector is different, and the function is different.

The way of action detection is different, one is to prevent overload, and the other is to prevent the leakage of the buried stove and pretend to be electricity.

The principle of the two is one of the differences between the air switch and the leakage switch, and the only difference is that the two are also different in terms of protection. The air switch is generally used for a long time to prevent the circuit from being overloaded, and in order to prevent the human body from being electrocuted, it only plays the role of a fuse. The Pailaoyou leakage switch is to prevent electric shock and leakage of the human body, and it will not play a big role in the overload of the circuit. Because the working principle of the two is different, the resulting security protection is also different, so the two can not be blindly mixed.

The second difference between air switch and leakage switch is that the way of motion detection is different. The safety switch is purely tripping because the circuit is too heavy to protect the safety of electricity; The residual current detected by the leakage switch is the residual current, which is the algebraic sum of the neutral wire and the inner phase of the protection loop current, so the device of this residual current only needs to avoid the leakage value, and it is very sensitive to cut off the leakage switch to prevent the click of direct contact with the leakage current. Therefore, in the way of action detection, this is the biggest difference between the two.

There are many differences between air switches and leakage switches. For example, in terms of protection, the air switch only plays a protective role relative to the current of the large circuit, mainly detecting the short circuit in the circuit and carrying the excessive current, and the leakage switch is relative to the small circuit to protect the province, mainly detecting the line equipment, protecting the safety of the human body and the safety of the equipment; In terms of tripping, the safety switch is through the live wire and the neutral line, if the current between the two wires is too large, it will lead to tripping, and the leakage switch is only because of the live wire, the human body will contact the live wire and the ground to form a loop, which will cause the device inside to automatically touch, to achieve the purpose of tripping, playing a protective role.

In addition to being a switch, the leakage protector is also a circuit leakage or electrical equipment leakage Chunling, the human body Liang Senbi accidental electric shock can be instantaneously powered off the device, and it also has the function of overcurrent and overvoltage protection.

There are two kinds of air absolute balance switches, one is without leakage protection, and the other is with leakage protection, collectively referred to as air switches.

The air switch without leakage protection is an overcurrent insurance, and the current of the line will trip immediately if it exceeds the rated current, of course, if the line is short-circuited, when the line current is larger, it will trip immediately. Missing manuscript.

The air switch with leakage protection is different, only when the first road leaks (when the live wire is to the ground, the equipment is to the ground, so that the current of the live wire and the neutral line is not equal), it will trip, and the leakage current will trip immediately as long as it exceeds 30 milliamperes.

If it is overcurrent, the air switch with leakage protection will generally not trip, only those without leakage protection trip.

Therefore, when using Fu Hongxiao, the main switch of the family and the switch for lighting generally use an air switch without leakage protection, and the socket uses an air switch with leakage protection.

FYI.

The air opening has the protection function, the leakage protector has it, and the leakage protection has one more important leakage protection function
