Title:
OPERATING MECHANISM OF CIRCUIT BREAKER AND CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2023/020483
Kind Code:
A1
Abstract:
The present invention relates to the low-voltage electrical field, and in particular, to an operating mechanism of a circuit breaker. A second connecting rod assembly of the operating mechanism comprises a second crank pivoted around a tenth axis, a third connecting rod, and a third crank pivoted around an eleventh axis; the second crank is further rotatably connected to the third connecting rod by means of an eighth shaft; the third connecting rod is further rotatably connected to the third crank by means of a ninth shaft; a first connecting rod assembly is further connected to the second crank by means of a seventh shaft; the shafts and the axes are arranged in parallel at intervals; the tenth axis or the eleventh axis coincides with a rotating axis of a moving contact mechanism, and the eighth shaft or the ninth shaft is in driving connection with the moving contact mechanism so as to drive the moving contact mechanism to rotate. The operating mechanism provides a plurality of modes of connection with the moving contact mechanism, thereby facilitating the design of a contact system of the circuit breaker. The present invention further relates to a circuit breaker comprising the operating mechanism, which can flexibly adjust a positional relationship between the operating mechanism and the moving contact mechanism according to requirements.
