Description

Special grounding device for substation

technical field

The utility model relates to a grounding device, in particular to a special grounding device for a substation.

Background technique

When the on-site equipment of the substation fails, in order to avoid further expansion of the power outage and protect the personal safety of maintenance personnel, it is usually necessary to set up a temporary grounding wire. At present, the common temporary grounding equipment is mainly a grounding device with bolt holes. When a temporary grounding wire needs to be set up when a fault occurs on site, the bolt hole end of the grounding device is welded to the grounding flat iron on the substation site to realize the grounding function. The disadvantages of the above-mentioned grounding device are: due to the need for welding, the grounding end of the grounding wire is easily damaged after repeated welding, and the contact is not firm, resulting in a decrease in conductivity and affecting the grounding function; moreover, welding is time-consuming and laborious, which increases the difficulty of maintenance work .

Utility model content

In order to solve the above defects of the existing technology, it is necessary to develop a low-cost, easy-to-install special grounding device for substations. The specific technical solution is:

A substation grounding device, comprising: a T-shaped grounding piece, a first grounding flat iron, a second grounding flat iron and a positioning screw; wherein: a positioning through hole is opened on the upper part of the T-shaped grounding piece, and the positioning screw passes through the T-shaped grounding The upper surface of the T-shaped grounding piece is inserted into the positioning through hole, the grounding wire is inserted into the positioning through hole and the grounding wire is fixed in the positioning through hole by tightening the positioning screw; the lower part of the T-shaped grounding piece is a threaded structure, which is consistent with the first fixed flat The first through hole of the iron matches the second through hole of the second fixed flat iron, wherein the first fixed flat iron and the second fixed flat iron are stacked up and down, so that the lower threaded structure of the T-shaped grounding piece is sequentially inserted into the first fixed through hole and second through hole.

The technology can achieve the following beneficial effects: effectively solving the problems that the grounding terminal is easily damaged and the grounding terminal does not match the grounding device.

Detailed ways

A substation grounding device provided by the present invention will be described in detail below with reference to the drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also adopt other alternative ways to implement for some known technologies; and the accompanying drawings It is only for more specific description of the embodiments, but not intended to specifically limit the present invention.

Referring to accompanying drawing 1, this figure shows the structural diagram of the grounding device of the present invention. The substation grounding device provided in this embodiment includes: a T-shaped grounding piece 2, a first grounding flat iron 4, a second grounding flat iron 5 and a positioning screw 1; wherein: a positioning through hole 3 is opened on the upper part of the T-shaped grounding piece 2 , the positioning screw 1 passes through the upper surface of the T-shaped grounding piece 2 and is inserted into the positioning through-hole 3, the grounding wire is inserted into the positioning through-hole 3 and the grounding wire is fixed in the positioning through-hole 3 by tightening the positioning screw 1; the T-shaped grounding piece The lower part of 2 is a threaded structure, which is matched with the first through hole 6 of the first fixed flat iron 4 and the second through hole 7 of the second fixed flat iron 5, wherein the first fixed flat iron 4 and the second fixed flat iron The flat irons 5 are stacked up and down, so that the lower threaded structure of the T-shaped grounding piece 2 is sequentially inserted into the first through hole 6 and the second through hole 7 to be fixed.

The working process of this embodiment is: when a fault occurs on the substation site and a temporary grounding wire needs to be set, the lower threaded structure of the T-shaped grounding piece 2 is rotated and inserted into the first through hole 6 of the first fixed flat iron 4 and the second fixed flat iron 5, so that the T-shaped grounding piece is fixed, then insert the grounding wire into the positioning through hole 3 on the upper part of the T-shaped grounding piece, and tighten the upper positioning screw 1, so that the grounding wire is firmly fixed In the positioning through hole 3. Wherein, the T-shaped grounding piece is preferably made of stainless steel.

The above-mentioned grounding devices are all fixedly connected to each other through threaded structures without welding, thus greatly improving the efficiency of maintenance work and effectively prolonging the service life of the grounding devices.

Finally, it should be noted that the above embodiments are only used to describe the technical solutions of the present utility model rather than limit the technical method, and the utility model can be extended to other modifications, changes, applications and embodiments in application, and therefore considered All such modifications, changes, applications, and embodiments are within the spirit and teaching scope of the present utility model.
