Title:
CIRCUIT BREAKER OPERATING MECHANISM AND CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2024/083053
Kind Code:
A1
Abstract:
The present invention relates to the field of low-voltage electrical appliances, and in particular to a circuit breaker operating mechanism. The operating mechanism is provided with two four-connecting-rod structures. One four-connecting-rod structure is composed of a second crank (21), a third connecting rod (23), and a third crank (25), and the third crank (25) has the same center of rotation as and is in driving connection with a phase pole rotary shaft (39); the other four-connecting-rod structure is composed of a second crank (21), a fourth connecting rod (29), and an N-pole rotary shaft (30), allowing the phase pole rotary shaft (39) and the N-pole rotary shaft (30) to rotate around different centers of rotation, thus providing more convenience for the design of the circuit breaker.
