The leakage protection circuit breaker, referred to as the leakage switch, also known as the leakage circuit breaker, is mainly used to protect the electric shock of people with a fatal danger when the equipment leakage failure occurs. It has overload and short -circuit protection functions.For short circuit, it can also be used as a non -frequent conversion start of the line.

Leakage protection railway brand
The first brand of the brand is the leakage protector of the Schneider brand, with air switch and leakage protection router. It is designed for three -phase and four -line line. The product has reliable insulation protection.The invasion of dust and other invasion; the fastest closure of the contact can be achieved when the voltage or current overload, thereby minimizing the damage, thereby effectively extending the service life of the leakage protector.Siemenss brand of leakage protection rails is also very good.It is made of armosetable plastic and has good heat insulation, wear resistance and insulation. Even in a harsh environment, it can play a fast leakage protection effect.The product of the Siemens brand is a green and environmentally friendly, energy -saving leakage protection router.The Zhengtai brand is a domestic leakage protection router. Whether it is overloaded or short -circuit, leakage, etc. in the line, leakage protection railway will play a protective role.The leakage protection circuit breaker will automatically power off in a short period of time, thereby cutting off the power of the entire line. The window of the transparent plastic shell can clearly see if the device works or power off, which is very convenient.
Leakage protection circuit breaker effect
The leakage protector can automatically cut off the power supply of the device when the equipment leakage, insulation destruction or the existence of people in the presence of people to prevent the equipment and its line from leaking electric shock, making the use of electrical appliances more secure.This kind of device is recommended to be installed in places where families, construction venues, and other people are exposed to more contacts to avoid frequent walking or contact with electrical engineering, which leads to the occurrence of electric shock safety accidents, threatening peoples life safety.
Principle of leakage protection circuit circuit
Under normal circumstances, the three -phase load current and the to -to -ground drain current are basically balanced, and the amount and approximate approximate of the coil current flowing through the transformer is zero, that is, the total magnetic flux generated by it in the iron core is zero, zero -sequentable transformers are secondary to secondary timeThe coil has no output.When an electric shock occurs, the electric shock current is through the earth into a circuit, which means that zero -sequential current is generated.This current does not flow back by the coil by the transformer, which destroys the balance, so there is zero -sequential magnetic flux in the iron core, so that the secondary coil output signal.This signal is amplified and compared to component judgments. If the predetermined action value is reached, the execution signal is sent to the execution of the execution component to move the gate and cut off the power.
