Description

{Insulation Structurue For Distribution Line}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wire line insulated switchgear, and more particularly, to a wire line insulated switchgear, The present invention relates to a wire line insulated wire line for an inside line of a distribution line that can prevent a safety accident such as a short circuit of an underground distribution line by allowing the plate portion to move up and down along an inner wall of a drain pipe before the underground distribution line is submerged.

Generally, electricity used in each home, office, and large-scale factory is supplied through substations equipped in each region.

The substation is installed for the purpose of modifying the voltage or the current and distributing the electric power. The electric power generated by the power plant is sent to the user through a transmission line or a distribution line.

Such a substation is usually installed on the ground. Since such a substation is exposed to the outside, there is a problem that short-circuit and short-circuit are caused due to external interference. The high-voltage cable exposed to the ground is underground, It was installed inside.

When the high-voltage cable is installed in the drain pipe as described above, the problem caused by the external interference can be solved because it is not exposed to the outside. However, since the length of the high-tension cable originally designed takes more time depending on the site conditions, But it continues to be implemented.

Especially, in the case of rainy season where the rainy season is raising, the rainwater will flow into the inside of the drain pipe, and the rainwater flowing into the inside of the drain pipe will be interrupted. The electrical interconnections connected to each other are flooded and electrical safety accidents such as electrical short circuits are frequently generated. As a result, each generation or factory receiving electricity from them is very inconvenient There was a problem.

In the case of a wire which is wired inside a drain pipe, if a transverse external force (for example, an earthquake transverse wave, an operator pulls for extension of a transmission line) acts, the connection state is easily released or a wire subjected to a strong tensile force There was a problem that it was damaged and connected to a short circuit.

In addition, in the case of buried in the ground, when the wires are connected to the electric wires, they are mutually twisted after being peeled off from the sheath of the electric wires, and an insulating tape is wound around the outer surfaces of the connected parts. However, when the thickness of the wire is large, it is difficult to install the wire.

In order to solve this problem, Korean Patent Registration No. 10-1083424 (November 11, 2011), which is a prior art, discloses a "line connection line inside a distribution line."

However, the conventional connecting rod has the advantage of solving the above-described conventional problems, but the electric wires installed in the water pipe substantially do not cross the drain pipe but the electric wires (ground distribution line: P / C) (See FIG. 11) because it is installed in the form of being fixed to the inner wall by a clamp. Therefore,

That is, due to the characteristics of the prior art in which the buoyant force is used to raise the electric wire, it is difficult to install the connection unit itself because the installation of the waterproof pipe facing the inner wall of both sides is not realized.

Korean Registered Patent No. 10-1083424 (Nov. 14, 2011) "Line connection line inside a power line"
