Description
Technical field
The utility model relates to the electric equipment field, relates in particular to a kind of low tension switch earthing device.
Background technology
The low tension switch earthing device is mainly used in the maintenance of equipment, in order to prevent in the maintenance process incoming call suddenly, can carry the abnormal current of regulation at the appointed time, therefore must be with the two ends of repair apparatus ground connection all.Earthed switch is generally output load side joint ground, the earthed switch of the equipment that closes simultaneously; Can prevent that like this incoming call causes electric shock accidents suddenly; Can drain residual charge in addition, help maintenance safety, can not cause like this by misdelivery electricity or the anti-electric shock accidents that send electricity to cause of circuit.Traditional breaker of plastic casing does not have earthing device, does not prevent counter sending under the electric situation, and level line maintenance safety can not be guaranteed, and influences maintenance personal's personal safety.
The utility model content
In order to improve the security performance of breaker of plastic casing earthed switch, the utility model provides a kind of low-pressure plastic shell switch ground connection interlocking gear.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: low-pressure plastic shell switch ground connection interlocking gear; Support is provided with copper bar, insulation board and ground connection goods of furniture for display rather than for use, and copper bar is provided with grounded bracket, moulds shell switch below and is provided with the switch arm-tie; Ground connection goods of furniture for display rather than for use below is provided with the ground connection arm-tie; Be provided with connecting plate between switch arm-tie and the ground connection arm-tie, the framework bottom is provided with the magnetic stripe support, and the magnetic stripe support is provided with the magnetic stripe pressing plate.
The backing plate top is provided with panel.
Framework is provided with handle, is provided with clamp between handle and the framework.
The low-pressure plastic shell switch ground connection interlocking gear of the utility model has tangible disjunction indication point, has guaranteed switch subordinate line maintenance safety, has improved maintenance personal's handling safety performance, better guarantee maintenance and operating personnel's personal safety.
