Description

Technical Field

[0001] The utility model relates to the technical field of power systems, in particular to a grounding device used in power systems. Background Art

[0002] The power system is an electric energy production and consumption system composed of power plants, transmission and transformation lines, power supply and distribution stations, and power consumption. Its function is to convert natural primary energy into electric energy through power generation devices, and then supply electric energy to various users through transmission, transformation and distribution. To achieve this function, the power system also has corresponding information and control systems in various links and different levels to measure, regulate, control, protect, communicate and dispatch the production process of electric energy to ensure that users obtain safe and high-quality electric energy. The main structure of the power system includes power sources, substations, transmission and distribution lines and load centers. The power points are also interconnected to realize the exchange and regulation of electric energy between different regions, thereby improving the safety and economy of power supply. The network composed of transmission lines and substations is usually called power network. The information and control system of the power system is composed of various detection equipment, communication equipment, safety protection devices, automatic control devices, and monitoring automation and dispatching automation systems. The structure of the power system should ensure the reasonable coordination of electric energy production and consumption on the basis of advanced technical equipment and high economic benefits.

[0003] At present, during the installation and use of power systems, grounding equipment is required to conduct electricity and improve safety. However, the structure of most grounding equipment is relatively simple, and the grounding wire is easily accidentally detached due to pulling due to accidental touch, which in turn causes accidents. Based on this, we propose an improvement to the grounding equipment used in power systems. Utility Model Content

[0004] The main purpose of the utility model is to provide a grounding device for an electric power system, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further solution of the utility model, the three wire inlets are sleeved with clamping pads, the front end of the mounting block is threadedly sleeved with three adjusting screws, and the rear ends of the three adjusting screws pass through the mounting block and are rotatably sleeved in the clamping pads.

[0008] As a further solution of the utility model, the front ends of the three adjusting screws are fixedly sleeved with rotating wheels, and the clamping pads are made of rubber material.

[0009] As a further solution of the utility model, mounting plates are fixedly connected to both sides of the base, and the front end of the protection box is rotatably connected to a cabinet door.

[0010] As a further solution of the utility model, the plurality of buffer springs are movably sleeved on the outer end of the telescopic pin, and one end of the winding column is fixedly connected to a handle.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a grounding device for an electric power system comprises a base 1, a protective box 3 and a grounding rod 6, two support plates 8 are fixedly connected at the upper end surface of the base 1 near the middle position, a winding column 9 is rotatably connected between the two support plates 8, the protective box 3 is fixedly connected to the upper end surface of the base 1, a mounting block 13 is arranged inside the protective box 3, telescopic pins 11 and buffer springs 12 are fixedly connected on both sides of the mounting block 13 and the rear end outer wall respectively, the other ends of the telescopic pins 11 and the buffer springs 12 are fixedly connected to the inner wall of the mounting block 13, a box opening 10 is opened at the rear plate of the protective box 3 near the upper end, and three wire inlets 14 are opened at the upper end of the mounting block 13.

[0023] In this embodiment, the three wire inlets 14 are all sleeved with clamping pads 15, the front end of the mounting block 13 is threadedly sleeved with three adjusting screws 16, the rear ends of the three adjusting screws 16 all penetrate the mounting block 13 and are rotatably sleeved in the clamping pads 15, and the grounding wire can be tightened by rotating the adjusting screws 16 to drive the clamping pads 15 to move.

[0024] In this embodiment, the front ends of the three adjusting screws 16 are all fixedly sleeved with rotating wheels to facilitate the rotation of the adjusting screws 16. The clamping pad 15 is made of rubber material to increase the friction force when clamping the grounding wire.

[0025] In this embodiment, both sides of the base 1 are fixedly connected with mounting plates 2, and the device can be fixedly installed by bolts penetrating the mounting plates 2, and the front end of the protection box 3 is rotatably connected with the cabinet door 4.

[0026] In this embodiment, a plurality of buffer springs 12 are movably sleeved on the outer end of the telescopic pin 11, and the telescopic pin 11 assists in guiding the buffer spring 12. A handle is fixedly connected to one end of the winding post 9, and the handle can be used to conveniently drive the winding post 9 to rotate.

[0027] In this embodiment, a socket tube 5 is fixedly sleeved in the base 1, a grounding rod 6 is movably sleeved on the inner end of the socket tube 5, and a wrapping bolt 7 is threadedly sleeved on the grounding rod 6, and the wrapping bolt 7 is used to sleeve the wire end of the grounding wire.

[0028] In this embodiment, the edges of the box opening 10 and the wire inlet 14 are both chamfered to avoid scratching the ground wire, and the mounting block 13 is arranged at a side position above the winding pole 9.

[0029] It should be noted that the utility model is a grounding device for an electric power system.
