Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door-type bidirectional socket for a power cable,

The present invention relates to a door type bidirectional socket of a power cable, and more particularly to a door type bidirectional socket of a power cable for fixing a power cable extending in both directions so as to be energizable 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.

At this time, the shock absorbing plate 113 extending from the rear to the outside of the wire receiving tube 111 is fixed to the front end of the insulation joint 120 by being fitted or tightly fitted.

Thereafter, the operator removes the fixing means 260 from the socket 200 and then rotates the door 230 to open the upper portion of the opening 240.

The worker draws the first power cable 100 and the second power cable 100 'through the connection holes 211 of the first connection part 210 and the second connection part 220. At this time, the operator inserts the guide groove 212 and the protrusion protrusion 121 so that the position of the protrusion 121 formed on the upper part of the connection hole 211 can be matched with the insertion slot 313a of the door 230 After the matching, the power cables 100 and 100 'are drawn in until they are caught by the stopper 122.

The contact ring 112 is drawn in such a way that the upper surface of the first receiving groove 312 of the lower conduit 320 and the insulating pipe 120 can be placed on the upper surface of the second receiving groove 313. [

The plug 110 of the first power cable 100 and the second power cable 100 'is connected to the partition wall 311 of the lower conduit 320 through the first connection part 210 and the second connection part 220, The door 230 is rotated and the upper portion of the opening 240 is sealed.

Thus, the upper conduit 310 is in close contact with the lower conduit 320 as the door 230 is rotated. At this time, the conduit tightening means 312a is in close contact with the ring contact means 112a, and the protrusion protrusion 121 of the insulation 120 is inserted into the insertion groove 313a of the upper conduit 310. [

Therefore, the first power cable 100 and the second power cable 100 'are connected and fixed so as to be mutually energized through the upper conduit 310 and the lower conduit 320.

Thereafter, the operator fixes the opening 240 and the door 230 by fastening the fixing means 260 through the fastening piece 241 and the through hole 242 of the fastening piece 232, And / or waterproof tape several times or more. Accordingly, the socket 200 connects the first power cable 100 and the second power cable 100 'to each other so as to be energized.

In addition, the present invention may include a configuration in which a power cable having different diameters and a power cable having a different diameter from the diameter of the socket 200 can be connected. This is shown in Fig. 6 as another embodiment of the present invention.
