Description

Breaker opening operation mechanism

Technical Field

The utility model relates to a circuit breaker separating brake operating device.

Background

The circuit breaker has two working states of closing and opening, when closing, the energy is released by the energy storage spring to drive the energy storage shaft to rotate, the elastic force of the tension spring can be overcome and the main shaft can be pushed to rotate in the rotating process of the energy storage shaft, and the travel switch is shifted to the closing position by the pull rod when the main shaft rotates; when the brake is switched off, the main shaft is driven by the elastic force of the tension spring to rotate reversely, and the travel switch is reset to the brake switching-off position by the pull rod.

The specific procedure for the circuit breaker opening operation is described in the invention patent publication No. CN110098082A, see fig. 3 thereof: when the switch is closed, the stop block is abutted with the limit wheel; when the brake needs to be opened, the lower button is connected to electrify the coil, a magnetic field is generated after the coil is electrified, the pin strikes the swing rod under the action of the magnetic field, then the swing rod drives the upper pressure rod to move upwards, the upper pressure rod then pulls the rotary table to rotate, the rotary table drives the lower pressure rod to move downwards, the lower pressure rod presses the extension arm to drive the limiting rod to rotate, the limiting rod moves backwards after the abdicating groove of the limiting rod rotates, the limiting wheel can push the limiting block away, and the main shaft rotates reversely.

The structure adopts the magnetic field generated by electrifying the coil to drive the knock pin to impact the swing rod, and is easily interfered by an external electromagnetic field to generate false operation, so that the brake-separating operation is unstable. In addition, the transmission stroke from the button to the limiting rod is too long, the related parts are very many, the structure is complex, and transmission faults are easy to occur.

SUMMERY OF THE UTILITY MODEL

The utility model provides a circuit breaker separating brake operating device, simple structure and the operation is reliable and stable. The utility model provides a technical scheme that its technical problem adopted is:

Compared with the background technology, the technical scheme has the following advantages:

1. the button, the shifting block, the rotating shaft and the stop block are sequentially in transmission connection, and the stop block can be controlled to rotate to give way to the limiting wheel of the main shaft by pressing the button, so that the brake is separated. This pivot just directly lets the dog in the pivoted time, and whole operating device part is few, simple structure, and direct by button control can not receive external magnetic field nature number to be closed up moreover, and the separating brake operation is reliable and stable.

2. The button can rotate around the cross rod, the button is convenient to mount, and the button can be directly mounted on the surface of the shell of the circuit breaker.

3. The top surface of the stop block is an arc-shaped surface protruding upwards, so that when the notch of the rotating shaft is aligned with the stop block, the top of the stop block can smoothly slide through the notch.
