Abstract

The invention discloses a circuit breaker with integration of an oil cup magnet yoke and an armature. The circuit breaker comprises a housing and an oil cup assembly arranged in the housing. The oil cup assembly consists of an oil cup, an oil cup cover, an oil cup magnetic yoke, a coil, an oil cup iron core, and a reset spring. The oil cup fixed in the housing has a cavity with one opened end; the oil cup cover is fixed on the opening of the oil cup cavity for sealing; the cavity of the oil cup is filled with medium oil; the reset spring and the oil cup iron core are arranged in the oil cup cavity; and the oil cup magnetic yoke is arranged at one side of the oil cup. A support is fixed in the housing; one end of the oil cup magnetic yoke is fixed at the support in a hinge joint; and an extending part that extends towards the oil cup cover and is in actuation with the oil cup cover when the circuit breaker is released is arranged at the other end of the oil cup magnetic yoke. On the basis of the structure, because extending part extends at the oil cup magnetic yoke to replace the existing armature, the structure of the circuit breaker is simplified, thereby improving stability of releasing of the circuit breaker.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker in which an oil cup yoke and an armature are integrated. Background technique [0002] Because the tripping of the traditional double gold circuit breaker is easily affected by temperature, many existing circuit breakers use the oil cup assembly to drive the tripping. The existing oil cup assembly generally includes an oil cup, an oil cup cover, an oil cup magnetic Yoke, coil, oil cup iron core, return spring and armature, the oil cup has a cavity with one end open, the oil cup cover is closed and fixed on the opening of the oil cup cavity, and the cavity of the oil cup is filled with medium oil , the return spring and the oil cup iron core are also located in the oil cup cavity, and one end of the return spring abuts on the oil cup iron core, the other end of the return spring abuts on the oil cup cover, and the coil is wound on the oil cup On the outer surface, the oil cu...
