Problems solved by technology

[0005] The purpose of the present invention is to provide a breaker fracture transmission device to solve the problem that the circuit breaker in the prior art uses two sets of operating mechanisms to realize the synchronous action of the active contact rod of the main break and the resistance moving contact rod of the resistance break. The overall transmission mechanism is complicated, and the technical problems of poor synchronization between the active contact rod and the resistance moving contact rod; at the same time, the invention also provides a circuit breaker using the fracture transmission device

Abstract

The invention discloses a circuit breaker break transmission device and a circuit breaker using the same. The circuit breaker break transmission device comprises a transmission crank arm which is provided with a fixed hinge point, a first power output point and a movable hinge point. A middle transmission rod is hinged to and assembled on the transmission crank arm at the movable hinge point. The middle transmission rod has a power point and a resistance point. A rotation force applying rod is hinged to the power point of the middle transmission rod, and the rotation force applying rod is used to apply an action force to the middle transmission rod to make the middle transmission rod to rotate about the movable hinge point in a direction opposite to the rotation direction of the transmission crank arm when the transmission crank arm drives the middle transmission rod to rotate about the fixed hinge point. The resistance point of the middle transmission rod is a second power output point which is synchronous with the first power output point in action and is in transmission connection with a movable contact rod of a second break of two breaks of a circuit breaker break unit. The break transmission device is simple in structure and simple and convenient to operate.

Description

technical field [0001] The invention relates to a breaker transmission device and a circuit breaker using the breaker transmission device. Background technique [0002] In high-voltage circuit breaker products, the opening and closing operation of the circuit breaker will cause operating overvoltage, resulting in damage to transmission lines and power equipment. The resistance unit connected in parallel with the main fracture is put into operation in advance to suppress the generation of operating overvoltage, and the resistance unit is put into operation in advance according to the early closure of the resistance fracture connected in parallel with the main fracture. A single break unit in an existing circuit breaker such as figure 1 As shown, it includes the main fracture 100 and the resistance fracture 200 arranged in parallel, the main fracture 100 includes the active contact rod 101 and the main static contact rod 102, and the resistance fracture 200 includes the resis...
