Since Faraday discovered the electromagnetic induction phenomenon, Siemens invented the motor soon after, marking the human beings completely entered the electrical age, but also marks the electricity this energy began to be used by human beings. In recent years, we can often hear about a fire, electricity leakage accident, and most of the cause of the fire is also because of electricity leakage. So this requires people to pay more attention to it, because although electricity provides us with a lot of convenience in life, but it is ultimately dangerous. Therefore, people have invented in the use of circuit breaker, relay, these two electrical appliances are the tools to protect the circuit. So today we will introduce the leakage relay in the use of the wiring method and the matters needing attention.
In leakage relay wiring work, the first should first understand the power on the relay and load signs, which is to familiar with the power of the relay, if the wrong, the power on will directly lead to the whole circuit short circuit, may burn out wire phenomenon, serious also may lead to the occurrence of fire.
The wiring method of leakage relay generally has three-phase five-wire system and single-phase three-wire system. When wiring the leakage relay, we must remember that the protection line of the relay can not pass through the current transformer. For the choice of wiring methods, both types have their own advantages, so there are not too many requirements. However, the requirements of the protection line need the user's attention, that is, the protection line needs to be connected to the protection line at the incoming end of the circuit, and the protection line cannot pass through the current transformer in the process of connecting the protection line.
It should be noted that the use of leakage relay electrical equipment can only be the equipment connected to the load side of the relay, some people not only one end of the electrical equipment in the power supply test, but also in the other end of the load side above, the impact of the contact is that the leakage relay does not work.
The choice of leakage relay, the choice of this product must choose quality pass, qualified products. At present, the main brands of electrical products in the market are mainly Schneider, Siemens, bull socket and so on, because this is related to the safety of the whole circuit, but also related to the safety of people, must not buy substandard products in order to save money.
Electricity, as a clean and pollution-free energy source, has been working for mankind for centuries. During this period, we also encountered a lot of regrettable accidents, which is enough to tell us that something that is good to us is also a threat to us to some extent. Therefore, for the use of electricity, we all must be careful, care about in life, and only in this way, our life can be more beautiful.
