Description

Insulation test grounding ring

technical field

The utility model relates to an electric inspection grounding ring, in particular to an insulating electric inspection grounding ring.

Background technique

At present, overhead insulated wires are generally used for laying medium and low-voltage lines in urban distribution networks. When repairing lines or equipment, in order to ensure the safety of maintenance personnel, it is necessary to hang the grounding protection line after verifying that the line is dead. When hanging the ground wire, the ground wire clamp and the wire must be in reliable contact, and the insulated wire cannot be hung, so the grounding ring for electric testing is used. Due to the unreasonable structural design of the existing grounding ring, it has the disadvantage of inconvenient installation, and the ring body of the existing electric test grounding ring is made of cast iron, and the ring body is prone to rust in the case of rain erosion Phenomenon, which affects the grounding performance of the entire electrical testing grounding ring.

Contents of the invention

The purpose of the utility model is to overcome the defects of the prior art and provide an insulating electric test grounding ring with simple structure, convenient installation and stable performance.

In order to achieve the above purpose, the utility model adopts an insulating electric test grounding ring, which includes a wire clip and a grounding ring body connected to the wire clip. The wire clip includes an upper cover and a lower cover for fastening the upper cover and the lower cover. The bolts of the cover, the outer cover of the upper cover and the lower cover are wrapped with an insulating protective cover, and the opening end of the insulating protective cover is provided with a cable tie for locking the insulating protective cover, and the grounding ring body is in the shape of In the shape of a semi-split ring, the outside of the grounding ring body is wrapped with a rubber insulating sleeve, and the center of the lower end of the grounding ring body is provided with a connecting part exposed outside the rubber insulating sleeve for installing a test rod.

The beneficial effects of the utility model are: the grounding ring body of the insulating electric test grounding ring is provided with a rubber insulating sleeve, thereby better preventing the external environment from eroding the grounding ring body, and the grounding ring body adopts a semi-open structure design, This facilitates the installation of the test rod, just put the test rod on the connection part of the grounding ring body, and the outside of the clamp is provided with an insulating protective cover, which can effectively prevent rainwater and other environmental factors from affecting the clamp and the wire. Damage to the connecting parts, so as to ensure the safe operation of the transmission line.

Detailed ways

As shown in Figures 1 and 2, the utility model embodiment is a grounding ring for insulated electric testing, including a wire clip 10, a grounding ring body 11 connected to the wire clip 10, and the wire clip 10 includes an upper cover 101, a lower Cover 102, bolts 103 for fastening the upper cover 101 and the lower cover 102, the outer cover of the upper cover 101 and the lower cover 102 is wrapped with an insulating protective cover 12, and the opening end of the insulating protective cover 12 is provided There is a cable tie 121 for locking the insulating protective cover 12. The grounding ring body 11 is in the shape of a semi-open ring. The outside of the grounding ring body 11 is wrapped with a rubber insulating sleeve 13. The grounding ring body 11 A connecting portion 111 exposed outside the rubber insulating sheath 13 for installing a test rod is provided at the center of the lower end of the bottom end. The grounding ring body of the insulating electric test grounding ring is provided with a rubber insulating sleeve, so as to better prevent the external environment from eroding the grounding ring body. It is only necessary to put the electric test rod on the connection part of the grounding ring body, and the outside of the clamp is provided with an insulating protective cover, which can effectively prevent rainwater and other environmental factors from damaging the connection between the clamp and the wire, thereby ensuring power transmission. safe operation of the line.
