Description

Grounding method and apparatus of electric pole

The present invention relates to a grounding construction method and a device for protecting the life and peripheral devices around the pole when a high voltage potential occurs in the pole due to lightning strikes, in particular, the minimum distance that the pole of the underground buried part shown in the regulations Insulate the insulation plate based on the distance and insulate the conductor band on the outer diameter surface of the insulated pole instead of the existing grounding rod, and then connect the ground wire drawn from the upper pole to the bottom of the pole through the hollow part of the pole. The present invention relates to a grounding construction method and apparatus for electric poles that can be used to derive the resistance value required by the law and to ensure easy construction and insulation distance, as well as prevent construction failures by the contractor in advance.

In general, in order to supply electric power that has undergone several stages of transformation in a substation to general consumers such as homes or buildings, distribution lines such as electric poles installed at regular intervals in each region are used.

The above distribution line ensures the operation of the protective relay in the case of high and low voltage contact and ground fault, thereby suppressing the abnormal voltage and protecting the device by abnormal voltage such as brain and surge. It is a known fact that the grounding is performed to prevent various electrical accidents caused by the leakage and short circuit.

In the grounding work of the conventional distribution line, as shown in FIG. 1, after excavating a pole of a certain depth to embed the pole 1, a hole having a certain depth and width toward one side of the pole of the pole is provided. Excavate one more, and bury the ground rod (3a) used for grounding in the pit with a tool such as a hammer and bury it, and then in-line construction connecting the lead wire (2a) installed in the pole (1) with each other, After excavating a pit of a certain depth to bury (1), excavate one more pit of constant depth and width to one side of the pit, and transfer two or more ground rods 3b used for grounding to the pit. In parallel with a certain distance from 1) using a tool such as a hammer to bury the buried, and then connected in parallel with the lead wire (2b) installed in the electric pole (1).

However, the above-described conventional construction method is used when the ground surface such as urban residential areas or adjacent roads is paved with concrete, and grounding rods are placed above 75cm underground (2M for serial connection and 1M underground for parallel connection). In addition, there is a risk of damage to the telephone line cables, and the excavation and recovery costs are excessive because of the excavation of paved roads and sidewalk blocks, as well as the grounding work of the prescribed regulations (construction standards: above 75Cm, minimum with Jeonju). The distance of 0.5M or more, and the distance between the ground rods and the minimum distance of 2M) is not easy, and the underground buried part of Jeonju was drilled to the pole of the pole by the orca crane (screw) vehicle during the recent relocation and construction work. As it is developed as an easy work process to insert and fix electric poles after digging soil, the door is actually difficult to work due to the prescribed grounding construction and surrounding environment. There point.

In order to solve the above problems, the present invention, after insulated the buried portion of the pole to be buried in the ground of the ground based on the minimum separation distance shown in the regulations, the conductor in the center of the outer pole insulated instead of the existing ground rod It provides the purpose of deriving the resistance value required by regulation by simple structure and construction method of connecting ground wire to lead terminal of conductor band by forming outer band.

A first step of enclosing the insulating plate in the lower part of the pole, and allowing one end of the coupling recess to be inserted into the other end of the coupling protrusion; After inserting the second catching hole of the conductor band into the second hook of one end of the insulating plate which is wound around the electric pole in the first step, the conductive recess of the conductor band is fitted to the insulating protrusion formed on the insulating plate and A second step of inserting the second catching hole formed at the other end into the second hanging hole of the other end of the insulating plate; A third step of connecting the ground wire drawn to the hollow part of the lower end of the electric pole to the lead terminal of the conductor band wound around the insulation plate in the second step; And a fourth step of embedding the electric pole when the ground wire is connected in the third step, so that the distance between the top of the insulating plate and the ground is at least 75 cm or more. A first step of bonding the adhesive layer of one inner side of the insulating plate to the outer diameter surface of the pole of the pole, and then outer coating several times so that the adhesive layer of the other end inner side is bonded to the outer diameter surface of the insulating plate; The adhesive layer on the inner side of the insulating protective film is bonded to the outer diameter surface of the insulating plate on the insulating plate wound around the electric pole by the first step, wherein the upper and lower jaws of the insulating protective film cover the upper and lower ends of the insulating plate to cover the insulating protective film. A second step; In the second step, the conductive recesses of the conductive band are externally fitted to the insulating protrusions of the insulating protective film that is enclosed by the insulating plate, and the third catching hole of one end of the conductive band is inserted into the third hook of the insulating protective film. A third step of fixing the other end to the second clip formed at one end thereof; A fourth step of connecting the ground wire drawn out to the hollow portion of the lower end of the electric pole to the lead terminal of the conductor band wound around the insulation plate in the third step; If the ground wire is connected in the fourth step, the electric pole is buried, the ground construction method comprising a fifth step to bury the distance between the top of the insulating plate and the ground at least 75cm or more.
