Wire Installation Structure of Conductive System of Leakage Circuit Breaker

Abstract

The invention relates to a wire installation structure of a conducting system of a residual-current circuit breaker. The wire installation structure comprises a circuit breaker housing and a releasinghousing that are combined together. Wire through holes are formed in the circuit breaker housing and the releasing housing respectively and correspondingly. A base part and a detachable part that arecombined and fixed are arranged at the circuit breaker housing in a split manner; the wire through hole of the circuit breaker housing is formed in the combination part between the base part and thedetachable part; and when the detachable part is taken down from the base part, the parts of circumferential edges of the wire through holes are open for communication with the external space. According to the wire installation structure provided by the invention, the structure is compact and reasonable; the thickness space of the circuit breaker housing and the releasing housing is utilized fully; the assembling becomes convenient and efficient. The wire installation mode of the conducting system is optimized and upgraded; and the convenience of electrician operation is improved.

Description

technical field [0001] The invention relates to a leakage circuit breaker, in particular to a wire installation structure of the conductive system of the leakage circuit breaker, and is used in conjunction with a small leakage circuit breaker with a zero-sequence transformer. Background technique [0002] The leakage circuit breaker is a switch that can automatically trip when the leakage current in the circuit exceeds a predetermined value, thereby providing leakage protection. The structure of the existing leakage circuit breaker is mainly composed of a circuit breaker and a release unit. [0003] The conductive system is an important mechanism in the leakage circuit breaker. In the prior art, it is necessary to perforate the corresponding wires of the circuit breaker and the tripper respectively. When assembling, the wires of the conductive system first pass through the wire perforation. The same or similar, and the appearance and specifications of the circuit breaker an...

[0003] The conductive system is an important mechanism in the leakage circuit breaker. In the prior art, it is necessary to perforate the corresponding wires of the circuit breaker and the tripper respectively. When assembling, the wires of the conductive system first pass through the wire perforation. The same or similar, and the appearance and specifications of the circuit breaker and the release are all standard specifications, resulting in relatively compact components in the housing, and the wire needs to be bent multiple times at a large angle in the narrow housing space to pass through the circuit breaker and release. The shell of the buckle brings a lot of inconvenience to the installation
