Embodiment 1

[0022] Install the "one"-shaped bare metal electrical inspection ground connection piece 5 made of a straight long strip of flat metal through the screw hole 7 on the "one"-shaped bare metal electrical inspection ground connection piece 5 through bolts and install it outdoors The fully insulated bow-shaped bus bar bridging part 3 is on the bus bar connecting plate 4 at both ends of the bow; it can realize the functions of facilitating the operation of electric inspection and installation of grounding wires. This embodiment can only be used on a bow-shaped busbar, and it is easy to discharge when it is close to the wall bushing, which is inconvenient to use.

Embodiment 2

[0024] Make a piece of straight and long flat metal into an "L"-shaped "L"-shaped bare metal electrical test ground connector 2, and pass the bolt upside down through the screw hole on the "L"-shaped bare metal electrical test ground connector 2 7 Install on the bus connection plate 4 on one side of the bow-shaped bus bar of the fully insulated outdoor busbar 1; or weld the upright top to the bus connection plate 4 upright; this embodiment can be installed on the bus bar upright or upside down. It is very convenient to use and convenient for electrical inspection, but when it is installed upside down on an outdoor fully insulated busbar, it is easy to cause the grounding wire to slip when installing the grounding wire.

Embodiment 3

[0026] Make a piece of straight and long flat metal into a "]" type "]" type bare metal electrical inspection grounding connector 6, and install it through the screw hole 7 on the "]" type bare metal electrical inspection grounding connector 6 with bolts On the busbar connecting plate 4 on one side of the outdoor fully insulated burden busbar 3. Just can realize the effect that is convenient for electric test and installation ground wire operation. This embodiment can be very convenient to use on the bus bar, and the electric test is convenient, and the installation of the ground wire does not have the problem of slipping the ground wire.

Abstract

The invention relates to the technical field of power transmission and transformation, in particular to a 10 kilovolts and below 10 kilovolts busbar electricity testing grounding device. An L-shaped bare metal electricity testing grounding connecting piece of the outdoor busbar electricity testing grounding device enables a piece of straight strip-shaped metal to be made in an L shape and is arranged upside-down on a bus connecting board on one side of a bow-shaped bus of an outdoor full insulation bundle busbar though a bolt, or a top end is straightly welded on the bus connecting board. The bare metal electricity testing grounding connecting piece is grafted on the outdoor full insulation bundle busbar through welding, or arranged on a bridge connection part of the outdoor full insulation bundle busbar, bird troubles can be prevented, and bus antioxygenation can be improved. Meanwhile, electricity testing and grounding wire installation are convenient. The outdoor busbar electricity testing grounding device has high practical value.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to an electric testing and grounding device for 10kV and below busbars. Background technique [0002] The Haixi area of ​​Qinghai Province is located in a plateau area with a harsh environment. Under the action of strong ultraviolet rays and windy and sandy weather conditions, the surface of live equipment is easily oxidized. 10kV and below busbar bridges are used in parallel with multi-layer busbars, and are fully insulated (such as figure 1 ) to prevent bird damage and improve the antioxidant effect of the busbar. However, the inconvenience caused by this is that there is a problem that the electric test and the installation of the grounding wire cannot be performed after the equipment is powered off. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of grounding device installed on...
