The invention relates to the technical field of electric leakage protection manufacturing, particularly relates to a front electric leakage forced protection system and method, and aims to solve the problems that in the prior art, when electric leakage faults happen to electric equipment, an electric leakage protector trips and is powered off to protect the electric equipment, but a pre-stage circuit for power supply is ignored at the moment so as to cause a potential safety hazard in a superior mechanism in a pre-stage stage circuit. According to the technical scheme, the front electric leakage forced protection system comprises an electric leakage detection module which is used for detecting and acquiring electric leakage detection data in the pre-stage circuit, a control module which is used for receiving the electric leakage detection data sent by the electric leakage detection module and controlling on and off of the power-off execution module according to the received electric leakage detection data, and a power-off execution module which is used for executing power-off protection processing so as to enable the superior mechanism in the pre-stage circuit to be tripped and powered off, and the application has the effects of protecting the pre-stage circuit when the circuit breaks down and reducing the possibility of electric leakage danger.
Description
technical field [0001] The present application relates to the technical field of leakage protection manufacturing, and in particular to a pre-leakage compulsory protection system and method. Background technique [0002] Since the invention and use of electricity by human beings, electricity has not only brought a lot of convenience to human beings, but also brought disasters to human beings. It may burn out electrical appliances, cause fire and cause unnecessary losses, or cause electric shock and bring life danger. With the gradual popularization of electrical equipment, the safety of electrical equipment has been paid more and more attention. So when all kinds of electrical appliances come one after another, all kinds of protectors are also born. Among them, there is a kind of special protection, called leakage protector. Leakage protector, commonly known as leakage switch, is a protective device used to prevent personal electric shock and electrical fire when the circ...
