Embodiment Construction

[0013] like figure 1 , figure 2 , image 3 As shown, an embodiment of a circuit breaker operating mechanism, the circuit breaker operating mechanism in this embodiment includes a mechanism chassis 10, on which the mechanism chassis 10 is rotatably equipped with a body crank arm 1, on which the mechanism chassis 10 is fixed A support 6 is installed, and a mechanism output shaft 7 is rotated on the support 6. The output shaft 7 of the mechanism is driven by the output crank arm 3 detachably installed on the support 6. The body crank arm 1 passes through the axial length The adjustable connecting rod 2 is in transmission connection with the output crank arm 3. The main body crank arm 1 forms a planar four-bar linkage mechanism through the axially adjustable connecting rod 2 and the output crank arm 3. The connecting rod 2 here consists of two axial The two ends of the connecting rod body 21 are respectively provided with connecting rod bodies 21 with opposite external threads,...

Abstract

The invention discloses a circuit breaker operation mechanism which comprises a mechanism chassis; a mechanism body crank arm and an output crank arm are rotationally assembled on the mechanism chassis; the mechanism body crank arm forms a plane four-link mechanism with the output crank arm through a connecting rod with an adjustable axial length; one end of the connecting rod is hinged with the mechanism body crank arm, and the other end of the connecting rod is hinged with the output crank arm; one end of the connecting rod which is hinged with the output crank arm is detachably hinged with the free end of the output crank arm; and a mechanism output shaft is detachably and fixedly connected onto the driving end of the output crank arm. The rotation angle of the mechanism output shaft can be adjusted by adjusting the length of the connecting rod and replacing the output crank arm with the appropriate length, so that the matching problem of the operation mechanism and circuit breakers with different input angles when the operation mechanism is preposed, i.e. the operation mechanism is in shaft-to-shaft connection with the circuit breakers.

Description

technical field [0001] The invention belongs to the technical field of high-voltage circuit breakers, and in particular relates to an operating mechanism of a circuit breaker. Background technique [0002] In the field of high-voltage circuit breaker technology, when the operating mechanism is front-mounted, that is, the operating mechanism and the circuit breaker are connected shaft-to-shaft, it is necessary to rigidly connect the output shaft of the operating mechanism to the input shaft of the circuit breaker, so that the circuit breaker The input angle is determined by the rotation angle of the mechanism output shaft of the operating mechanism. However, because different circuit breakers have certain requirements on the output angle of the operating mechanism, that is, the rotation angle of the output shaft of the mechanism, it is necessary to solve the problem of matching the output angle of the operating mechanism with the input angle of different circuit breakers, so ...
