An integrated intelligent permanent magnet circuit breaker

Abstract

The invention discloses an integrated intelligent permanent magnet circuit breaker. The integrated intelligent permanent magnet circuit breaker is characterized in that a capacitor 8, a permanent magnet driver 7, a permanent magnet mechanism 6 and a surge controller 3 are arranged in a case 1, namely, a control terminal and the permanent magnet circuit breaker are designed into one case; a short shaft 13 is arranged at one end of the permanent magnet mechanism 6 and is connected with a long shaft 5; long pins 4 are arranged at two sides of the long shaft 5 respectively; one end of each breaking spring 2 is fixed on the corresponding long pin 4 and the other end of each breaking spring 2 is connected with the case 1; the surge controller 3 is located below the breaking springs 2; the tensile force, acting on the long pins 4, of the breaking springs 2 is opposite to the closing retention force of the permanent magnet mechanism 6; a breaking-closing shaft 11 is arranged on a side plate 9 of the case; travel switches 10 are symmetrically arranged at two sides of one end, in the case 1, of the breaking-closing shaft 11; and a breaking-closing handle 12 is arranged outside the case 1. According to the integrated intelligent permanent magnet circuit breaker, a control terminal box body and an installation material are saved, installation and construction are convenient, a connection cable is omitted, the hidden danger caused by cable ageing is reduced and the security performance is improved.

Description

technical field [0001] The invention particularly relates to an integrated intelligent permanent magnet circuit breaker. Background technique [0002] With the rapid development of power distribution system automation, permanent magnet circuit breakers are used more and more widely, but permanent magnet circuit breakers must be used in conjunction with control terminals to achieve intelligent automation of lines. The existing permanent magnet circuit breaker and the control terminal are two separate box mechanisms, installed separately, and connected by cables in the middle. This not only causes inconvenience to the installation and construction, but also the cables are exposed to wind and sun outdoors, which is easy to age and brings hidden dangers to line safety. Contents of the invention [0003] The purpose of the present invention is to design an integrated intelligent permanent magnet circuit breaker. [0004] The integrated intelligent permanent magnet circuit bre...
