Abstract
The invention relates to the technical field of electric equipment and discloses a grounding interlocking mechanism for a low voltage plastic casing switch, which is a grounding device for a low voltage switch. A copper bar, an insulating plate and a grounding swinging piece are arranged on a bracket; a grounding bracket is arranged on the copper bar; the plastic casing switch is arranged on the bracket; a switch pull plate is arranged below the plastic casing switch; a grounding switching piece is arranged inside the plastic casing switch; a grounding pull plate is arranged below the grounding swinging piece; a connecting plate is arranged between the switch pull plate and the grounding pull plate; and the lower part of a frame body is provided with a magnetic strip bracket on which a magnetic strip pressing plate is arranged. The grounding interlocking mechanism has obvious breaking indicating points; with the adoption of the grounding interlocking mechanism, the maintenance safety of switch subordinate lines is guaranteed, namely that the safety performance of the grounding switch of a plastic casing circuit breaker is significantly improved; and meanwhile, the operation safety of maintenance staff is greatly improved; and the grounding interlocking mechanism plays the role of guaranteeing the personal safety of maintenance staff and operators.
Description
Technical field
The present invention relates to the electric equipment technical field, relate in particular to a kind of low-pressure plastic shell switch ground connection interlocking gear, is 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, has prevented counter sending under the electric situation, and subordinate's line maintenance safety can not be guaranteed, and influences maintenance personal's personal safety.
Summary of the invention
In order to solve technical problem of the prior art, the invention provides a kind of low-pressure plastic shell switch ground connection interlocking gear.Purpose is the security performance that can significantly improve the breaker of plastic casing earthed switch.
The technical solution adopted for the present invention to solve the technical problems is:
Low-pressure plastic shell switch ground connection interlocking gear is on support, to be 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; It is rack-mount to mould the shell switch, moulds shell switch below and is provided with the switch arm-tie; Inside is provided with the ground connection goods of furniture for display rather than for use, and ground connection goods of furniture for display rather than for use below is provided with the ground connection arm-tie, is 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.
Described backing plate top is provided with panel.
Described framework is provided with handle, is provided with clamp between handle and the framework.
The invention has the beneficial effects as follows:
Have tangible disjunction indication point, guaranteed switch subordinate line maintenance safety, promptly significantly improve the security performance of breaker of plastic casing earthed switch.Simultaneously also improve maintenance personal's handling safety performance greatly, can play the effect of better guarantee maintenance and operating personnel's personal safety.
