Leakage circuit breaking device of electrical equipment

Abstract

The invention discloses an electric leakage circuit breaker of electrical equipment, which comprises a circuit breaker main body, constant temperature devices are symmetrically arranged on the front surface of the circuit breaker main body, the front surface of the circuit breaker main body is fixedly connected with the back surfaces of the constant temperature devices, and plugging devices are uniformly arranged at two ends of the circuit breaker main body. The inner wall of the plugging device is fixedly connected with the two ends of the circuit breaker main body, the constant temperature device comprises a fastening device, a heat dissipation copper plate is arranged in the fastening device, the inner wall of the fastening device is movably connected with the two ends of the heat dissipation copper plate, and contact devices are uniformly arranged on the outer surface of the heat dissipation copper plate. The outer surface of the heat dissipation copper plate is movably connected with the inner wall of the contact device, and the two ends of the contact device are symmetrically provided with fixing rods. The problem that a traditional small electric leakage circuit breaker easily loses the working capacity after the heat of the device reaches a certain limit is solved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a leakage circuit breaker for electrical equipment. Background technique [0002] The small leakage circuit breaker is a current-limiting circuit breaker with overload and short-circuit protection. At present, the small leakage circuit breaker on the market includes a small leakage circuit breaker body. Although this leakage circuit breaker body can prevent personal electric shock , but because the usual small leakage circuit breaker body works in a high-temperature working environment, and when the heat generated by itself reaches a certain limit, the small leakage circuit breaker will lose its working ability, so the heat dissipation effect of the small leakage circuit breaker is improved. It is a current problem to improve the heat dissipation effect while ensuring the structural strength. A leakage circuit breaker for electrical equipment is proposed to solve the above-men...
