Description

an auxiliary grounding wire

technical field

The utility model relates to the technical field of electric power production, in particular to an auxiliary grounding wire used for the switching operation of a main transformer in a substation.

Background technique

When switching the main transformer of the substation, the operator is required to install a grounding wire, the purpose is to protect the personal safety of the personnel and avoid the occurrence of personal electric shock casualties. Since the length of the commonly used grounding wire is shorter than the height of the main transformer from the ground, and the grounding piles are mostly buried, far away from the vertical distance between the grounding wire and the ground, the length of the currently installed grounding wire cannot meet all switching operation requirements. Cause the main transformer switching operation to time out.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide an auxiliary grounding wire with reliable connection and convenient operation.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

An auxiliary grounding wire, which includes a grounding wire and an insulating rod, a clamp is fixed on the insulating rod, one end of the grounding wire is connected to the clamp, and the other end is connected to a flat-type grounding clamp A, a flat-type grounding clamp B, and a bolt-type grounding wire clamp.

As for the auxiliary grounding wire, the flat grounding clamp A includes a clamp body, a threaded hole is provided on the upper side plate of the clamp body, a screw is passed through the threaded hole, and a fastener is provided at the bottom of the screw.

The above-mentioned auxiliary grounding wire, its flat grounding clamp B includes a clamp body, a threaded hole is provided on the lower side plate of the clamp body, a screw is passed through the threaded hole, and a pressure plate is provided on the top of the screw.

As for the auxiliary grounding wire, handles are provided on the screws of the flat grounding clamp A and the flat grounding clamp B.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages:

The auxiliary grounding wire has simple structure, reasonable and novel design, and convenient operation. The grounding pile connection makes the operator no longer worry about the selection and handling of the grounding wire. The connection is reliable, which reduces the switching operation time of the main transformer, ensures the safety of personnel and equipment, improves work efficiency, and ensures the reliability of power supply.
