Abstract

The invention relates to atransmission rod for multi-phase parallel-controlled circuit breakers. The transmission rod comprises a transmission rod pulling button (1), a break-off auxiliary spring (2), a mounting positioning component (3), a self-locking mechanism (4) and a locking plate component (5). Circuit breakers in the multi-phase parallel-controlled circuit breakers applying the transmission rod can control one phase of circuit separately, and can have different rated loads; when one phase of circuit breaker in the parallelcircuit breakers is switched off, the other circuit breakers are switched off at the same time.

Description

technical field [0001] The invention relates to a transmission rod of a circuit breaker used for multi-phase parallel control, and belongs to the technical field of product structure. Background technique [0002] Circuit breakers are used to protect circuits from damage to lines or other electrical components caused by current overload. The protection function of miniature circuit breakers, which are usually used for domestic or low-load commercial use, is provided by thermal deformation unlocking devices. This unlocking device consists of a bimetallic part which heats up in response to changes in the line current and thus deforms. The bimetal part then unlocks the operating mechanism that controls the on-off of the product, and the mechanism controls the components in the circuit breaker that are connected with the external circuit and are responsible for conducting current. [0003] For example, circuit breakers are used in aircraft and aviation electrical systems, wher...
