Abstract

A shunt-excitation auxiliary combined accessory of a circuit breaker comprises an accessory shell, a shunt-excitation tripping assembly and an auxiliary switch assembly, wherein the shunt-excitation tripping assembly and the auxiliary switch assembly are arranged in the accessory shell. The shunt-excitation tripping assembly comprises a shunt-excitation magnetic flow release, a shunt-excitation microswitch and a shunt-excitation drag rod push rod, wherein the shunt-excitation magnetic flow release is installed on one side in the accessory shell, one end of the shunt-excitation magnetic flow release is connected with the shunt-excitation draw rod push rod, the shunt-excitation draw rod push rod is in drivingly matched with a drag rod of an operating mechanism, and the shunt-excitation microswitch is used for controlling on-off of a shunt-excitation magnetic flow release circuit. The auxiliary switch assembly comprises an auxiliary microswitch used for indicating on-off of the circuit breaker and further comprises an auxiliary matched rotating shaft push rod which is pivotally connected to the accessory shell. The shunt-excitation tripping assembly further comprises a shunt-excitation matched rotating shaft push rod.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a low-voltage molded case circuit breaker, in particular to a shunt auxiliary combined accessory of the circuit breaker. Background technique [0002] Molded case circuit breakers are devices that protect electrical equipment and lines. All functions of the molded case circuit breaker are realized by the body and accessories. Accessories can be optional to meet different application occasions. [0003] The accessories used by molded case circuit breakers are installed on both sides of the operating mechanism. In the case of a four-pole circuit breaker, there are three accessory slots. Three-pole circuit breakers have two accessory slots. But in the case of a two-pole circuit breaker, there is only one accessory slot. There are fewer accessory slots, which cannot meet the application requirements of many occasions. Especially the current molded case circuit b...
