Description

A grounding wire for a substation

technical field

The utility model relates to a maintenance tool for a substation, in particular to a grounding wire for a substation.

Background technique

With the rapid development of the times, people's living standards are constantly improving, and the electricity consumption in cities is also gradually increasing. Improving the reliability and economy of power grid operation has become the primary responsibility of electric power workers; in order to effectively use conductor materials and use For heat dissipation, the high-current busbar is often made into a groove shape or a diamond shape, and there are also circular shapes, but this has caused a lot of inconvenience for our maintenance personnel when installing grounding wires for power outage maintenance; the wires used in conventional substations are in During installation, because the shape of the busbar is different, sometimes it cannot meet our daily maintenance needs, and it cannot be well grounded; this will bring safety hazards to our maintenance personnel, and it will also affect the operation of our power grid. There are potential safety hazards; conventionally used grounding wires have a single connection at the wire end, which cannot meet the grounding installations for buses of different shapes.

Utility model content

The utility model provides a grounding wire for a substation that can meet the requirements for installing grounding devices on buses of different shapes.

The technical solution adopted by the utility model is: a grounding wire for a substation, including a universal joint, a grounding wire connection point and an insulating operating rod; the insulating operating rod is a cylindrical structure; the universal joint is arranged on the insulating operating rod The upper end of the ground wire; the connection point of the ground wire is set on the end of the insulating operating rod close to the universal joint for fixing the ground bus.

Further, the upper part of the universal joint is provided with a screw with external threads.

Further, the connection point of the ground wire is a screw provided on the insulating operating rod.

The beneficial effects of the utility model are:

(1) The utility model is equipped with universal joints, which can meet the needs of installing grounding devices on buses of different shapes;

(2) The utility model improves the safety of operators and equipment, and avoids safety accidents of personnel and equipment;

(3) The utility model has the advantages of simple structure, easy operation, flexibility, portability and high applicability.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Figures 1 and 2, a grounding wire for a substation includes a universal joint 1, a grounding wire connection point 2, and an insulating operating rod 3; the insulating operating rod 3 is a cylindrical structure; the universal joint 1 is set On the upper end of the insulating operating rod 3; the grounding wire connection point 2 is set on the end of the insulating operating rod 3 close to the universal joint 1 for fixing the grounding busbar.

The upper part of the universal joint 1 is provided with a screw rod with external threads; this structural design facilitates the fixing of the grounding wire.

The connection point 2 of the ground wire is a screw arranged on the insulating operating rod 3; this structural design can be used to fix the busbars of different types and sizes by adjusting the tightness of the screw.

When in use, busbars of different shapes can be grounded only by replacing the universal joint 1, and the busbar can be fixed through the connection point 2 of the grounding wire. There is no need to replace the grounding wire according to the model of the busbar, which saves costs and is also convenient to use.

The utility model has the advantages of simple design, convenient operation, flexibility, safety and reliability; the device reduces the potential safety hazards of operators and equipment, and avoids the occurrence of personnel and equipment safety accidents; thereby achieving safe and reliable power supply for users during operation At the same time, it not only creates good economic benefits, but also creates a win-win situation for social benefits; the utility model can better ensure that the grounding terminal is well grounded when the grounding device is installed in the actual substation maintenance operation, greatly reducing While reducing the labor intensity of operators, the potential safety hazards of operators also ensure the safe operation of the power grid, creating a win-win situation of economic and social benefits.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
