Description

Bidirectional socket of power cable {BYDIRECTION SOCKET FOR POWER CABLE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bidirectional socket of a power cable, and more particularly, to a bidirectional socket of a power cable securing a power cable extending in both directions so as to extend the length of the power cable.

Generally, a cable connected to a distribution line that supplies power to a load from a transformer has various sizes, and a large number of people have a weight and diameter that can be lifted or moved by the human force.

For example, in the past, power cables extending from the main transformer to distribution lines are connected through a distribution gas isolation switch or a mobile gas isolation switch.

The gas insulated switchgear (GIS) is equipped with a vacuum interrupter (VCB), a disconnector, a three-stage switch (DES), a main bus and a branch bus in a grounded metal tank to fill the SF6 gas As a product, it is a power switchgear that has advantages such as miniaturization of a substation, improvement of safety and reliability, easy operation and maintenance, and harmony with environment (see Japanese Patent Laid-Open No. 2002-165320).

Therefore, conventionally, a first power cable extending from the main transformer, a second power cable extending from the gas insulated switch to the main transformer, and a third power cable extending from the gas insulated switch to the power distribution line are used.

In this case, the first power cable of the main transformer and the second power cable of the gas insulated switchgear are connected by a straight-line connection (for example, an interference fit bushing installed in a welding or gas insulated switchgear).

Since the connection of the power cable using the direct connection material may cause wear or damage of the plug, it is not possible to reuse it when the gas insulated switch is moved or the power cable is removed. Therefore, There is a problem in that it is increased.

In addition, since the power cable is for transmitting high-voltage power, the load of the power cable is considerable, and the worker's body may be stressed, thereby increasing the working time.
