Embodiment 1
[0037] Please refer to figure 1 and figure 2, the manual operating mechanism of the permanent magnet molded case circuit breaker, including a housing 1, the housing 1 is provided with a switch assembly 2, a tripping assembly, a moving contact assembly 4, a static contact 5, and a The lock 7 at the proximal end of the head assembly 4, a part of the switch assembly 2 is connected with a part of the tripping assembly, and the other part of the tripping assembly is connected with the lock 7, the switch assembly 2 is opposite to The housing 1 rotates and drives the tripping assembly to rotate, and the tripping assembly drives the movable contact assembly 4 to move axially relative to the stationary contact 5, so that the movable contact assembly 4 is far away from the movable contact assembly 4. The terminal contacts or separates from the distal end of the static contact 5, so as to realize the closing and opening of the permanent magnet molded case circuit breaker.

The invention relates to a manual operation mechanism of a permanent magnet type molded case circuit breaker, which comprises a shell, a switch assembly, a tripping assembly, a moving contact assembly, a static contact and a lock catch arranged at the near end of the moving contact assembly are arranged in the shell, one part of the switch assembly is connected with one part of the tripping assembly, and the other part of the tripping assembly is connected with the lock catch. One part of the tripping assembly is connected with the shell, the other part of the tripping assembly is connected with the lock catch, the switch assembly rotates relative to the shell and drives the tripping assembly to rotate, and the tripping assembly drives the moving contact assembly to axially move relative to the static contact, so that the far end of the moving contact assembly is in contact with or separated from the far end of the static contact; according to the utility model, switching-on and switching-off of the permanent magnet type molded case circuit breaker are realized, the situation that the permanent magnet type molded case circuit breaker requires to switch on the circuit breaker firstly and then supply power to the circuit breaker under the condition that the input end is powered off, but a controller cannot control switching-on under the condition that the circuit breaker is powered off is avoided, and the use safety and reliability of the circuit breaker are improved.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a manual operating mechanism of a permanent magnet molded case circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can make, carry and break current under normal circuit conditions and can make, carry and break current under abnormal circuit conditions within a specified time. A circuit breaker switch that integrates a contactor and a molded case circuit breaker, is favored by users due to its long life, high reliability and fast closing speed. [0003] In the past, the closing and opening functions of permanent magnet molded case circuit breakers were controlled by the controller. When the circuit breaker is powered off, the controller cannot close the circuit breaker, so the use of the circuit breaker in this situation has certain limitations. [0004] The Chinese invention patent with the document number CN101494133B di...
