Abstract
The utility model relates to a high-voltage circuit breaker and an operation mechanism thereof. According to the high-voltage circuit breaker, a moving contact insulating pull bar of a high-voltage circuit breaker body is driven to act through a crankshaft. A main journal of the crankshaft is in driving connection with an output end of a power device so that the power device inputs rotation torque to the whole crankshaft. The moving contact insulating pull bar is rotatably assembled on a connecting rod journal of the crankshaft so that the moving contact insulating pull bar can reciprocate in the high-voltage circuit breaker body under pushing-pulling function of the connecting rod journal of the crankshaft in the rotation process of crankshaft, thereby driving the moving contact insulating pull bars of three high-voltage circuit breaker bodies to act simultaneously, driving the high-voltage circuit breaker to perform switching on/off action through crankshaft rotation. Therefore in switching on/off action of the high-voltage circuit breaker, the power device and the crankshaft rotate in a same rotation direction always. The rotation mode of the high-voltage circuit breaker is different from the rotation mode in which a rotating motor and the crankshaft respectively perform forward rotation and reverse rotation in the prior art. Furthermore the high-voltage circuit breaker settles the following defects in the prior-art high-voltage circuit breaker: short service life and low operation reliability.
