Measuring cabinet and circuit breaker cabinet double interlocking device

Abstract

The invention relates to the technical field of power equipment, in particular to a measuring cabinet and circuit breaker cabinet double interlocking device. The measuring cabinet and circuit breaker cabinet double interlocking device comprises a cabinet body front bending plate, a front wire rope interlocker, a fixing plate, a limiting copper sleeve, a cam, a lower sliding plate, an inner sliding plate, a lock core, a lower door plate and a rear wire rope interlocker, wherein the fixing plate, the lock core and the rear wire rope interlocker all are arranged on the cabinet body front bending plate; the lower door plate is located at the lower part of the cabinet body front bending plate; the limiting copper sleeve and the cam are connected to the lock core; the front wire rope interlocker, the lower sliding plate and the inner sliding plate are connected to the fixing plate; the rear wire rope interlocker comprises a interlock fixing plate, an interlock inner sliding plate and an interlocker baffle plate; and the lower sliding plate and the inner sliding plate are provided with a lower sliding plate reset spring and an inner sliding plate reset spring respectively. The measuring cabinet and circuit breaker cabinet double interlocking device comprises two interlocked mechanisms of a mechanical key and a mooring rope interlocker, which can be individually used, can also be simultaneously used and completely play a role in protecting personnel and equipment. The safety can be mechanically ensured without assembling a lower door screw.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a double interlocking device for a metering cabinet and a circuit breaker cabinet. Background technique [0002] Due to the different requirements of power supply bureaus in various regions for power distribution equipment, some southern regions require that the circuit breaker cabinet and the metering cabinet should be equipped with mechanical double locking devices in the switch combination with metering cabinets. At present, this device has not appeared in the market. Between the original circuit breaker and the metering cabinet, no matter whether the circuit breaker is opened or closed, the metering cabinet can open the lower door by removing the lower door screw. For those who are not familiar with the equipment, it may be difficult Cause electric shock hazard, can't completely put an end to the accident, poor security. Contents of the invention [0003] ...
