The invention discloses a switching-off action mechanism, a circuit breaker and an opening method. The switching-off action mechanism is provided with a first elastic part, a first transmission part and a second transmission part, the first transmission part and the second transmission part are provided with a first abutting face and a second abutting face respectively. The elastic force of the first elastic part acts on the second transmission part; when the first abutting surface abuts against the second abutting surface and the first electric contact contacts with a second electric contactin the circuit breaker, the first electric contact contacts with the second electric contact in the circuit breaker. And the first transmission part and the second transmission part are kept relatively static, and when the first abutting surface and the second abutting surface are converted from an abutting state to a separation state, the second transmission part rotates to enable the first electric contact and the second electric contact to be separated so as to realize the switching-off purpose. The switching-off action mechanism provided by the invention has the advantages of few parts andsimple assembly.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an opening mechanism, a circuit breaker and an opening method. Background technique [0002] The circuit breaker is a common circuit protection device. Generally speaking, the circuit breaker has two states of opening and closing. When the circuit breaker is in the closed state, the circuit operates normally. In the case of maintenance, etc., the circuit breaker needs to perform an opening action to cut off the circuit. However, in the prior art, the opening action mechanism of the circuit breaker has many parts and is complicated to assemble. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an opening action mechanism, a circuit breaker and an opening method in view of the above-mentioned defects of the prior art, aiming to solve the ...
