Description

Anti-breakage hardware device for substation equipment

technical field

The utility model relates to the technical field of power transmission equipment maintenance, and relates to a gold fitting device for preventing broken strands of substation equipment.

Background technique

The connection between the substation bus down conductor and the outlet terminals of electrical equipment (such as transformers, circuit breakers, isolating switches, etc.) is connected through equipment clamps. The equipment clamps are generally compression type, one end is the wire crimping area, and the other end is through the bolt. To connect with electrical equipment, due to the guaranteed electrical separation distance, the length of the down-conductor is different with the voltage level. In the substation in the windy area, the longer down-conductor will be on the upper and lower sides of the down-conductor under the action of wind load. Larger stress is generated at the end, especially the connection angle between the lower end and the electrical equipment is different, and a certain bending moment will also be generated.

In the existing equipment, the connection between the down conductor and the electrical equipment is generally through the equipment clamp made of aluminum material. Since the down conductor is a flexible body and the equipment clamp is a rigid body, the connection between the two is the place where the stress is most concentrated. , In order to consider the sufficient connection strength of the equipment clamp, the size and thickness of the equipment clamp will be increased to ensure that the equipment clamp will not be deformed and broken during long-term operation. However, in strong wind areas, under the action of strong winds all year round, the reciprocating swing of the down conductor will cause strand breakage at the outlet wire of the clamp, seriously affecting the safe and stable operation of the power grid.
