Operating mechanism chassis truck interlocking device and interlocking method thereof

Abstract

The invention relates to an operating mechanism chassis truck interlocking device and an interlocking method thereof. A chassis truck rotating shaft of the chassis truck locking device and a chassis truck locking plate are installed on a chassis truck support in a parallel mode, and a limiting hook of the chassis truck locking plate is provided with an interlocking plate. A switching-on pinch plate is installed on a pinch plate shaft between clamping plates, and one end of the switching-on pinch plate abuts against the a switching-on half shaft between the clamping plates. The operating mechanism chassis truck locking device is characterized in that a half-circular half shaft end at one end of the switching-on half shaft extends out of the clamping plate on one side, the straight edge of the half-circular half shaft end of the switching-on half shaft abuts against the side edge of one end of the interlocking plate, the interlocking plate is installed on the clamping plates through a first fixing screw, parts where the first fixing screw is located of the interlocking plate are provided with sliding holes, the limiting hook of the chassis truck locking plate and an interlocking hook at the other end of the interlocking plate are buckled, and the chassis truck locking plate is driven by the rotation of the chassis truck rotating shaft to rotate. The chassis truck rotating shaft is shaken, the chassis truck locking plate is lifted, and an operating mechanism cannot be switched on. When the chassis truck rotating shaft is shaken in place, the chassis truck locking plate is pressed by the chassis truck rotating shaft, and the operating mechanism can be switched on.

Description

technical field [0001] The invention relates to an operating mechanism chassis vehicle of a high-voltage switch electrical appliance, in particular to an interlocking device and an interlocking method for the operating mechanism chassis vehicle. Background technique [0002] The chassis of the operating mechanism of the high-voltage switch is used to push and withdraw the circuit breaker, and is used as an auxiliary operation for on-off of the circuit breaker and the busbar. The chassis structure of this type of operating mechanism is disclosed in the Chinese patent literature with the application number 200920190382.3, the date of authorization announcement is 2010.05.26, and the name of the utility model is "indoor high-voltage vacuum circuit breaker". The high-voltage vacuum circuit breaker includes a primary conductive part, a box And operating mechanism, chassis car, the primary conductive part is composed of vacuum interrupter, vacuum pole, static contact and moving co...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above disadvantages, the purpose of the present invention is to provide the field with an operating mechanism chassis interlocking device and its interlocking method, so that it can solve the problem of complex interlocking structures and increased errors in existing similar operating mechanisms. As a result, the failure of the interlock affects the internal operation of the mechanism, making the mechanism unable to operate normally.
