Abstract
The utility model discloses a detachable cover plate grounding soldering lug. The detachable cover plate grounding soldering lug is in the shape of a circular ring, an internal diameter of the detachable cover plate grounding soldering lug and a bolt hole on a back cover plate are consistent in aperture, an external diameter of the detachable cover plate grounding soldering lug is slightly greater than an external diameter of a pad of the bolt used for fixing the back cover plate, a material is stainless steel, thickness of the material is generally 1.5-2.0mm, the grounding soldering lugs are two at the left side and the right side and respectively soldered at one side of bolt fixing holes of the back cover plate prepared by sheet metal, and surfaces of the soldering lugs can not be sprayed with plastic or paint during subsequent plastic spraying or paint spraying processing of the back cover plate. After well-processed back cover plate, surfaces of the left and right grounding soldering lugs have excellent conductive performance, and the back cover plate, a side plate and a vertical column can be effectively grounded, and the back cover plate is convenient to dismount and mount.
Description
Technical field
The utility model belongs to the electric equipment field, particularly relates to a kind of earth protective device.
Background technology
Ground protection is for preventing that insulation damages from causing equipment live to jeopardize the protective device that personal safety arranges.In the high-tension apparatus field by aobvious important.
Take the high voltage converter cabinet as example, the link in the realization cabinet is effectively received and has also been run into a lot of problems on the ground connection busbar.See the side plate in the accompanying drawing 1, the ground connection of back shroud rear column, side plate is connected bolt to be connected with base with base, is connected dead earth busbar on the base with base with earth connection on the side plate.Back shroud is detachable block, but for personal safety, must be the back shroud effective grounding, accompanying drawing 2 is exactly common solution: at first weld respectively grounding nail on back shroud, side plate and column, connect with earth connection.Then the ground connection busbar of being connected with base by the grounding nail on the side cover plate connects, and has so just reached the purpose of ground connection.
But, said method has also caused other problem simultaneously, be that back shroud arranges for the installation and maintenance internal unit, after connecting earth connection like this, each dismounting all will be pulled down earth connection, and also to all to connect every line when installing, this just give equipment installation, safeguard and brought a lot of inconvenience.This earthing method and device mainly address the above problem.
Summary of the invention
Goal of the invention: invent a kind of ground connection weld tabs of dismountable cover plate, so that cover plate does not need to connect just energy effective grounding of earth connection, and easy accessibility.
Technical scheme: a kind of ground connection weld tabs of dismountable cover plate, it is characterized in that be shaped as circularly, its internal diameter is consistent with the bolt hole aperture on the back shroud, external diameter is slightly larger than the fixedly external diameter of the pad of the used bolt of back shroud; Described ground connection weld tabs is symmetrical, about each one, be welded on respectively bolt fixing hole one end of the back shroud both sides that panel beating makes; The surface of weld tabs is at the follow-up plastic-blasting of back shroud or spray paint when processing not by plastic-blasting or spray paint;
The material of described ground connection weld tabs is stainless steel, and thickness is 1.5-2.0mm;
To be installed to the back shroud of described ground connection weld tabs on the cabinet, add plain cushion with corresponding bolt again and shell fragment is fixed on side plate and the column, press in position corresponding to back shroud installing hole or weld self-clinching nut or welded nut at side plate and column, back shroud, side plate, column just can be good at linking together like this, and have and well conduct effect.
Advantage of the present utility model and beneficial effect: through the back shroud of above-mentioned processing, about two ground connection weld tabs surfaces have good electric conductivity (to annotate: make although back shroud itself is metal, but usually all to pass through surface treatment, prevent surface oxidisation, reach attractive and durable effect, such as plastic-blasting or spray paint, thereby its surface can not be conducted electricity), as long as be connected to side plate on the ground connection busbar of base by earth connection, the all effective groundings of back shroud, side plate, column, and the back shroud dismounting is all very convenient.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
A kind of ground connection weld tabs of dismountable cover plate is characterized in that, is shaped as circularly, and its internal diameter is consistent with the bolt hole aperture on the back shroud, and external diameter is slightly larger than the fixedly external diameter of the pad of the used bolt of back shroud; Described ground connection weld tabs is symmetrical, about each one, be welded on respectively bolt fixing hole one end of the back shroud both sides that panel beating makes; The surface of weld tabs is at the follow-up plastic-blasting of back shroud or spray paint when processing not by plastic-blasting or spray paint;
The material of described ground connection weld tabs is stainless steel, and thickness is 1.5-2.0mm;
To be installed to the back shroud of ground connection weld tabs on the cabinet, add plain cushion with corresponding bolt again and shell fragment is fixed on side plate and the column, press in position corresponding to back shroud installing hole or weld self-clinching nut or welded nut at side plate and column, back shroud, side plate, column just can be good at linking together like this, and have and well conduct effect.
Back shroud through above-mentioned processing, about two ground connection weld tabs surfaces have good electric conductivity (to annotate: make although back shroud itself is metal, but usually all to pass through surface treatment, prevent surface oxidisation, reach attractive and durable effect, such as plastic-blasting or spray paint, thereby its surface can not be conducted electricity), as long as side plate is connected to by earth connection on the ground connection busbar of base, all effective groundings of back shroud, side plate, column, and also the back shroud dismounting is all very convenient.
