CN202422954U - 10KV incoming bridge grounding conductor terminal for transformer - Google Patents

Abstract

The utility model provides a 10KV incoming bridge grounding conductor terminal for a transformer, which comprises an L-shaped conductor terminal body, wherein one side arm of the conductor terminal body is provided with a hanging rod which is used for hanging a ground wire conductor terminal joint. After a grounding conductor terminal is arranged on the joint of a 10KV incoming bridge aluminum busbar of the transformer, the ground wire which arranged when the transformer is repaired can be reliably and firmly hung on a bus bridge, residual charge after the transformer is powered off can be effectively led into the ground in time, and safe foundation for the equipment in maintenance period is established.

Description

A transformer 10KV incoming bridge grounding conductor end

technical field

The utility model relates to a grounding conductor end of a 10KV incoming line bridge of a transformer.

Background technique

The existing 110KV 220KV transformer 10KV incoming line bridges are basically connected by aluminum bars. According to the on-site investigation results, there are mainly the following dangerous points when the ground wire is installed on the 10KV incoming bridge: (1) Some ground wires cannot be installed on the 10KV incoming bridge, which does not meet the relevant regulations of safety regulations. (2) Since the insulating layer of the outer sheath of the aluminum row does not make contact in place, it is not easy to introduce all the remaining charges into the ground, and the installed grounding wire does not meet the requirements of the on-site work ticket. (3) Even if it is installed, the grounding wire cannot be reliably fixed, and it is easy to fall off from the conductor end. (4) It is inconvenient for the operating personnel to operate, which may cause it to fall off during operation and hit the on-site operators. (5) Time-consuming and labor-intensive, the operation is very troublesome, and the planned operation cannot be completed within the specified time.

Utility model content

The purpose of the utility model is to solve the above-mentioned technical problems existing in the prior art, and provide a transformer 10KV incoming bridge grounding conductor end.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

The grounding conductor end of the transformer 10KV incoming line bridge of the utility model includes an L-shaped conductor end body, and a hanging rod for hanging the ground wire conductor end joint is arranged on one side arm of the conductor end body.

A hole is provided on one side arm of the conductor end body, and the hanging rod for suspending the conductor end joint of the ground wire is threadedly connected with the L-shaped conductor end body.

After installing the grounding conductor end of the utility model at the connection of the aluminum row of the 10KV incoming line bridge of the substation, the grounding wire installed during the maintenance of the transformer can be hung on the bus bridge reliably and firmly, and the remaining power after the power failure of the transformer can be promptly removed. The charge is effectively poured into the ground, laying the foundation for the safety of the equipment during maintenance. Put an end to various risk factors that can not be reliably installed on the busbar bridge due to equipment manufacturing reasons, and ensure the safety of construction during maintenance.

Detailed ways

The grounding conductor end of the transformer 10KV incoming bridge of the utility model includes an L-shaped conductor end body 1, and a hanging rod 2 for hanging the ground wire conductor end joint is arranged on one side arm of the conductor end body 1 . A hole is provided on one side arm of the conductor end body, and the hanging rod for suspending the conductor end joint of the ground wire is threadedly connected with the L-shaped conductor end body.

After the grounding conductor end is installed at the connection of the aluminum bar of the 10KV incoming bridge of the substation, the grounding wire installed during the maintenance of the transformer can be hung on the busbar bridge reliably and firmly, and the residual charge after the power failure of the transformer can be effectively discharged in time. The earth lays the foundation for the safety of equipment during maintenance.
