Speaking of the leakage switch, I believe many of my friends are not too familiar with it. I think this is a kind of switch that will leak electricity. In fact, this is not the case. The leakage switch is a kind of protection type switch. It has anti-leakage and can be cut off automatically when leaking. The function of the power supply can protect the safety of our people and property. Although it is not easy to see in our lives, its role can not be ignored. Now every family will install a leakage switch. So today we will talk about the principle of leakage switch , and let us know the type of leakage switch. First, what is the leakage switch 1. The leakage switch, also known as the leakage protection switch, is a kind of protection switch that can cut off the power when it is leaking at home, which can protect our safety. The leakage switch is composed of the output current winding and the input current winding and the secondary winding. In normal life, it is no different from the ordinary switch. The output and input current are also the same, but the circuit safety hazard occurs. It will play a very big role. 2. There are currently three types of leakage switches on the market, namely voltage type, current type and pulse type. The voltage type leakage switch is mainly used on the transformer, but since it cannot be graded, it is basically no longer used. Second, the principle of leakage switch 1. The leakage switch is divided into two windings on the iron core, one is the input current winding, and the other is the output current winding. When there is no leakage, the input current and the output current are the same, above the iron core. The current is also the same so that the current induced by the third winding is not excessive, causing a trip. 2. If the leakage switch is added to the device, even if the device does not leak, but because the current in the core is unstable, this will cause the illusion of leakage, which will cause the leakage switch to automatically trip. Third, the type of leakage switch 1. The first type is only the leakage protection function. It should be used in conjunction with fuses and relays when in use. 2. The second is to increase the overload protection function based on the leakage protection function. 3. The third type is to increase the short-circuit protection function on the basis of the leakage protection function, and can also automatically power off when a short circuit occurs. 4. The fourth type adds the functions of overload, overvoltage and undervoltage on the basis of the leakage protection function, and realizes the protection of various circuit faults. 5, leakage protector, this protector can be divided into two according to the tripping action and actuator, one is the electronic leakage protector, and the other is the electromagnetic leakage protector. The actuator of the electronic leakage protector is a relay, which is powered off by a relay. Its advantages are that it is more sensitive, the cost is lower, and the error is small. The actuator of the electromagnetic leakage protector is an electromagnetic tripping device, which is powered off by an electromagnetic tripping device. Its advantage is that it has strong anti-interference and stable leakage characteristics, but it is relatively high in cost. . The above content is the information about the principle of leakage switch brought to you by this small series. I hope that I can bring you some help. I believe that everyone has a certain understanding of the leakage switch after reading. To learn more about home improvement, please stay tuned to the home of the decoration.
