Novel electric leakage protection device

Abstract

The invention discloses a novel electric leakage protection device, which comprises an electric leakage setting unit, a central processing unit, an electric leakage acquisition unit, an electric leakage display unit, a test key and a reset key, and is characterized in that the electric leakage setting unit is connected with the central processing unit through a circuit board, and the central processing unit is connected with the electric leakage acquisition unit, the electric leakage display unit, the reset key and the test key through a circuit board. The electric leakage protection device is low in manufacturing cost, simple in structure, convenient to use and high in work efficiency. Through setting a safe electric leakage range which not only does not affect normal operations of a circuit but also does not cause personal injuries, the novel electric leakage protection device does not interrupt power supply when an electric leakage condition within the safe electric leakage range is detected to occur, displays electric leakage information through an electric leakage display unit, gives out an early warning and cuts off the circuit when the electric leakage condition exceeds the safe electric leakage range.

Description

technical field [0001] The invention relates to the field of leakage protection, in particular to a novel leakage protection device. 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 could burn out electrical appliances, cause a fire, or give people an electric shock. In order to make people use electricity safely and avoid many unnecessary losses, someone invented the leakage protector. The leakage protector is a protective device used to prevent personal electric shock and electrical fire when the circuit or electrical insulation is damaged and short-circuited to the ground. On the line, the latter is dedicated to protection against electrical fires. Leakage protectors can be classified according to their protection functions, structural features, installation methods, operation methods, number of poles and lines, ...

Problems solved by technology

[0003] The current leakage protection device is sensitive and can trip and cut off the circuit once leakage occurs. However, some working environments have high requirements for normal use of electricity, and tripping and power failure are not allowed, but the requirements for leakage are lower. Existing The leakage protection device can not meet the demand
