Description

Technical Field

[0001] The utility model relates to the technical field of grounding devices, in particular to a distribution network grounding device. Background Art

[0002] The distribution network refers to a power grid that receives electric energy from the transmission network or regional power plant, and distributes it locally or step by step according to the voltage to various users through distribution facilities. It is a network composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. Under normal circumstances, the metal casing of electrical equipment is insulated from the live parts, and the casing will not be charged. However, if the insulator inside the electrical appliance is aged or damaged, electricity may be transmitted to the metal casing. If the casing is not grounded, people will get an electric shock if they touch it. If the metal casing is grounded, the current will flow into the earth through the ground wire, and people will not get an electric shock if they touch the live metal casing. Grounding is to use a thicker wire, connect one end of it to the casing of the electrical equipment, and bury the other end underground to a certain depth.

[0003] The prior art publication number CN214898921U discloses a grounding device for a distribution network, comprising a fixing box, a mounting plate being provided at the bottom of the fixing box, a top plate being provided at the top of the fixing box, a fixing plate being fixedly connected to the bottom of the top plate, a side of the fixing plate being slidably connected to the surface of the fixing box, a threaded ring being fixedly connected to the side of the fixing plate, a bolt being provided on the side of the threaded ring, the bolt passing through the fixing plate and the fixing box and being threadedly connected to the threaded ring, a connecting plate being fixedly connected to the bottom of the top plate, and a winding drum being rotatably connected to the side of the connecting plate via a rotating shaft.

[0004] When in use, it is only inserted into the soil through the grounding head, and its stability is poor. After a long period of outdoor use, the insulating grounding device can easily become loose due to wind or accidental collision, resulting in a loose connection between the insulating grounding device and the ground, which can easily cause the insulating grounding device to tip over. At the same time, the grounding wire is directly exposed to the outside, with poor protection effect, and it is easy to fall off when accidentally pulled. Therefore, it is necessary to design a distribution network grounding device to solve the above problems.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
