Problems solved by technology

However, the traditional vacuum switch actuator based on the magnetic transmission principle of permanent magnets still drives the permanent magnets in a linear motion, that is, by driving one of the permanent magnets to move in a straight line, the other permanent magnet moves in a straight line. Therefore, the above problems cannot be solved

Abstract

The invention discloses a multi-path synchronous control multifunctional vacuum circuit breaker, and the circuit breaker comprises a manual switch, an overcurrent protection mechanism, a plurality ofvacuum switch actuating mechanisms and a plurality of overcurrent triggering mechanisms; each vacuum switch actuating mechanism comprises a vacuum cavity, and a wire inlet end static contact, a wire outlet end static contact and a moving contact are arranged in each vacuum cavity; the moving contacts of the plurality of vacuum switch actuating mechanisms are driven by a manual switch and a drivingpiece of the overcurrent protection mechanism, the vacuum switch actuating mechanisms further comprise first permanent magnets which are arranged outside the vacuum cavity and can drive the moving contacts to move linearly through magnetic force, and the first permanent magnets are provided with magnet center holes. A driving piece of the manual switch and overcurrent protection mechanism is a rotating shaft, and the rotating shaft penetrates through magnet center holes of the first permanent magnets of the plurality of vacuum switch execution mechanisms. The rotating shaft is adopted as a driving part of the manual switch and the overcurrent protection mechanism, the occupied space is smaller, and miniaturization design and accurate control of the whole circuit breaker are facilitated.

Description

technical field [0001] The invention relates to a vacuum circuit breaker, in particular to a multi-functional vacuum circuit breaker with multi-channel synchronous control. Background technique [0002] Vacuum circuit breaker, also known as vacuum switch, is a circuit breaker with contacts placed in a vacuum cavity. It is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing. Compared with air Air circuit breakers (also known as air switches) have the advantages of small size, light weight, suitable for frequent operations, and no maintenance for arc extinguishing, and have been widely used in high and low voltage distribution networks. [0003] The basic structure of a vacuum circuit breaker includes a vacuum switch actuator (including a vacuum cavity and a moving contact, a static contact, etc.), a manual switch mechanism, an overcurrent protection decoupling (that is, decoupling and hooking) mechanism and an overcurren...
