The release is connected with a switch, the release is further connected with the EAMCU processing control module, the fault arc data storage module, the residual current collection module, the current collection module and thevoltage collection module are connected with the EAMCU processing control module, and each module mentioned above is supplied with power by the power source, and the fault arc data storage module isconfigured to store features of the fault arc; and the current transformer and the residual current transformer are arranged in a load circuit. The novel electric leakage and arc fault integrated protection device is a novel electrical fireproofing product capable of effectively identifying the arc faults and implementing protection for a distribution circuit to avoid electrical fire generation atpresent.

Description

technical field [0001] The invention relates to a new leakage and arc fault comprehensive protection device. Background technique [0002] In recent years, statistical data show that fires caused by electrical causes top the list of all kinds of fires. About 30% of the fires are caused by the aging or unreasonable configuration of residential electrical lines, and it is continuing to rise at an average annual rate of 1%. 70% of electrical fires are caused by electrical fault arcs. Electrical fire accidents occur frequently and can easily cause devastating disasters. On the basis of traditional miniature circuit breakers, we increase the protection of arc faults to prevent fires caused by arcs. [0003] The arc is a free gas with high temperature and high conductivity, and the instantaneous spark generated by the current passing through the gas medium. When the electrode contacts disconnect the current, as long as the current reaches 80∽100mA and the voltage reaches 10∽20V...

AI Technical Summary

Problems solved by technology

A bad arc may cause the line to catch fire, or affect the normal operation of the equipment, and the alarm should be reported immediately or the main circuit should be disconnected

This method of distinguishing the arc is based on the angle of whether it can endanger the safety of electricity, and does not reflect any physical parameters. Therefore, it is difficult to judge whether it is an arc fault, and it also puts forward higher requirements for the arc fault protection device. requirements
