Description
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.
SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to prevent water from being infiltrated by water flowing into a drain pipe by allowing electric wires to move along an inner wall of the water pipe.
According to an aspect of the present invention, there is provided an insulated wire line insulated base for a power line, the insulated means including at least one underground distribution line electrically connected to the insulated means, A driving part fixedly installed on the water pipe to be rotatable with the plate part and configured to move the plate part up and down according to the rotation direction, and a water supply part fixed to the plate part or the driving part, And a control unit for controlling the driving unit by sensing the water level, wherein the plate unit includes a plate-like moving plate installed on the wall surface of the drain pipe so as to be able to move up and down, Is inserted into the moving plate And a second clamp which is provided between the pair of first clamps and in which the insulating means formed on the underground distribution line is inserted and protruded on an outer surface of the second clamp, A driving motor fixedly installed on an outer surface of the mounting plate so as to be controllable by the control unit, an outer surface of which is rotatably screwed to the elevating groove, And a lifting screw which is rotatably coupled to the driving motor to move the lifting and lowering moving plate, and the control unit is fixed to the moving plate so as to be positioned below the first clamp or the second clamp, A water level sensor provided so as to detect the water level sensor, A microcomputer fixed to the mounting plate to apply power to the driving motor to rotate the driving motor forward or backward according to the detection result of the water level sensor to elevate the moving plate, And a timer for determining a detection time of the water level sensor and providing the determination time to the microcomputer.
According to the present invention, an underground distribution line disposed on an inner wall of a drain pipe is fixed to a plate portion so as to be electrically connected to each other by insulation means differently from conventional ones, and before the underground distribution line is submerged according to the water level sensed by the water level sensor The plate can be moved up and down along the inner wall of the drain pipe by the driving unit, thereby preventing a safety accident such as a short circuit of the underground distribution line.
