specific Embodiment

[0039] According to a specific embodiment of the present invention, the closing button 3 includes a button 31 and a button seat 32, the button 31 is slidably fitted on the button seat 32, and the button seat 32 is rotatably hinged on the box base of the circuit breaker.

[0040] According to a specific embodiment of the present invention, the connecting rod assembly 2 includes a hinge block 21 and a pull rod 22, the hinge block 21 is rotatably installed on the box base frame of the circuit breaker, and one end of the hinge block 21 abuts against the closing button 3 On the button 31 of the switch, the closing button 3 is pressed, and the button 31 slides in the button seat 32. When the button 31 slides, the hinge block 21 is pushed to deflect. The pendulum will pull the pull rod 22, and the other end of the pull rod 22 is hinged on the detent connecting plate 1, that is to say, when the pull rod 22 is pulled to move toward the closing button 3, the detent connecting plate 1 wil...

Abstract

The invention relates to the field of high-voltage circuit breakers, and particularly relates to a circuit breaker closing interlocking mechanism which comprises a pawl connecting plate, a limiting plate and a deflection plate, wherein the pawl connecting plate is fixed to a pawl, the pawl connecting plate or the pawl is in linkage with a closing button through a connecting rod assembly, the closing button drives the pawl to rotate through the connecting rod assembly so as to be unlocked, the limiting plate is arranged close to the pawl connecting plate, the limiting plate and the pawl connecting plate are matched to limit rotation of the pawl, the limiting plate is driven by the driving module to abut against the pawl connecting plate, the deflection plate is configured to be rotationallyinstalled, when the energy storage cam reaches the energy storage keeping position, the deflection plate is driven to deflect and triggers a position detection module, the position detection module is used for outputting an interlocking signal, and the driving module drives the limiting plate to abut against the pawl connecting plate according to the interlocking signal. According to the embodiment, the technical problem that secondary closing is easily caused due to the fact that the high-voltage circuit breaker does not have protection measures in the closing energy storage state in the prior art is solved.

Description

technical field [0001] The invention relates to the field of high-voltage circuit breakers, in particular to a circuit breaker closing interlocking mechanism. Background technique [0002] A high-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the function of the relay protection device when the system fails. Perfect arc extinguishing structure and sufficient breaking capacity can be divided into: oil circuit breaker (more oil circuit breaker, less oil circuit breaker), sulfur hexafluoride circuit breaker (SF6 circuit breaker), compressed air circuit breaker, vacuum circuit breaker device etc. [0003] According to different working states, high-voltage circuit breakers are divided into three states: closing, closing energy storage, and opening. Cause misoperation, and press the closing button when closing ...
