Circuit breaker with leakage protection function and opening and closing function

Abstract

The invention relates to a circuit breaker with an electric leakage protection function and opening and closing functions. A trip opening unit and an operation unit are arranged at two sides of a circuit breaker unit group respectively; the trip opening unit can drive a trip device of the circuit breaker to trip when electric leakage appears in a circuit, thereby opening the circuit breaker; and a drive motor in the operation unit can drive the circuit breaker to open or close. Therefore, according to the circuit breaker with the electric leakage protection function and the opening and closing functions, electric leakage protection of the circuit breaker can be achieved, electric opening and closing operations of the circuit breaker can be achieved and implementation of automatic control on the circuit breaker is facilitated.

Description

technical field [0001] The invention relates to a circuit breaker with leakage protection function and opening and closing function, and belongs to the technical field of miniature circuit breakers. Background technique [0002] Miniature circuit breakers are widely used in various electrical occasions in production and life. With the development of miniature circuit breaker technology, the basic technology of miniature circuit breakers is becoming more and more mature, and the basic performance of miniature circuit breakers is increasing and developing steadily; due to With the extensive use of miniature circuit breakers, the cost of miniature circuit breakers is more and more valued by users. Miniature circuit breakers with good performance and low cost are favored by customers, while the market competitiveness of miniature circuit breakers with higher cost is obviously lower. For this reason, the manufacturing cost of miniature circuit breakers has gradually become a key ...

AI Technical Summary

Problems solved by technology

The leakage protection circuit breaker in the prior art generally does not have the ability of electric opening and closing, which is not convenient for automatic control of the circuit. Generally, after the leakage protection circuit breaker trips and opens, the circuit breaker is manually closed to make the circuit open. connected, this method is not conducive to the automatic control of the circuit

In addition, the leakage detection unit in the leakage circuit breaker in the prior art is spliced ​​on the side of the circuit breaker unit group, so the conductive connecting wire between the circuit breaker unit group and the leakage detection unit needs to be bent for a certain distance, and the consumed There are many conductive connecting wires. Since the conductive connecting wires are generally made of copper material with high cost, the manufacturing cost of the circuit breaker is also relatively high.
