Abstract

The invention discloses a novel electric leakage protection device. The novel electric leakage protection device comprises a fault signal starting and transmitting device and a fault signal receiving and actuating device, and is characterized in that the fault signal starting and transmitting device comprises a fault starting device and a fault signal transmitting device; the fault signal receiving and actuating device comprises a fault signal receiving device and a fault actuating device, the fault starting device and the fault signal transmitting device are installed on a circuit board together and fixed at a site within a protected scope, and the fault signal receiving device and the fault actuating device are installed in a leakage protector together. The novel electric leakage protection device has the advantages of wide protection scope, multiple protection function, ability of cutting off a power supply safely and quickly when a fault occurs and ability of achieving a purpose of well protecting the human body and equipment.

Description

technical field [0001] The invention relates to a leakage protection device, in particular to a novel leakage protection device. Background technique [0002] Currently installed and applied leakage protection devices have relatively simple functions. Generally, they can automatically cut off the power supply only when there is leakage in the electrical equipment. When a fire or other failure occurs in the user's house, it is easy to cause a short circuit of the wire, and the original leakage protector cannot remove the failure in time, further expanding the fire area or causing other safety accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a leakage protector that can act quickly and in advance when a fire or other accident occurs in the area where the electrical equipment is located on the basis of the original function of the leakage protector. , A new type of leakage protect...
