Abstract
Discloses a door type bidirectional socket of a power cable. The present invention relates to an electric power supply apparatus for an electric vehicle, which comprises an opening for supporting a first power cable and a second electric power cable which are opened upward from a socket for connecting power cables drawn in both directions so as to be energized, It is possible to prevent wear of the first power cable and the plug of the second power cable and to prevent deformation of the shape by fixing the upper conduit and the lower conduit made of the conductive metal to the door that hermetically seals the opened upper side, .
Description
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.
SUMMARY OF THE INVENTION It is an object of the present invention to solve such conventional problems by providing a door type bidirectional socket for a power cable capable of preventing abrasion or deformation of a plug of a power cable drawn in both directions and reusing the drawn- The purpose is to provide.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, A second power cable extending in the other direction; An insulating connection for inserting the plugs formed at the ends of the first power cable and the second power cable, respectively; A socket for connecting the first power cable and the second power cable so as to be energized; And a fixing fixture fastened to an outer surface of the first power cable and the second power cable and fastened to the socket, wherein the plug includes a lead receiving pipe for receiving a lead; A contact ring inserted into the outer surface of the lead receiving tube and fastened to the socket; And a shock absorbing plate extending outwardly from an outer surface of the lead receiving tube, wherein the socket includes: a first connecting portion having a connection hole through which the first power cable is drawn out; A second connection part having a connection hole through which the second power cable is drawn out; An opening for supporting a plug of the first power cable and the second power cable, the upper side of which is open through the first connection part and the second connection part; A lower conduit fixed to an open upper surface of the opening and energizing the plugs of the first power cable and the second power cable drawn through the first connection and the second connection; A door hinged to be rotatable with the opening to seal the opened upper side of the opening; An upper conduit secured to the door such that the door is rotated to close the upper portion of the opening and to close the lower conduit to energize the plugs of the first power cable and the second power cable; And a reinforcing member made of a conductive metal, which is fastened to the outer surface of the contact ring to compensate for the difference in diameter between the contact ring and the upper and lower conduits when a difference in diameter between the contact ring and the upper and lower conduits occurs, Wherein the insulation includes at least one protrusion protruding longitudinally from the outer surface; And a stopper protruding from an outer surface of the first connection portion and the second connection portion to prevent the first connection portion and the second connection portion from being drawn into the first connection portion and the second connection portion, One or more guide grooves formed in the grooves inwardly of the inner surface of the guide grooves and guiding the projecting projections of the engaging projections, An elastic ring which seals a space which is fixed to the inner surface of the connection hole and which is spaced apart from the insulation connection; And a ring fixing groove formed in the inner surface of the connection hole and fixed to the elastic ring, wherein the first connection portion and the second connection portion are divided into a door shape of a power cable, It provides a bidirectional socket.
Therefore, according to the present invention, since the electric conductor for energizing the plug of the electric power cable is divided and integrated into the door rotatably fixed so as to seal the inside of the plug, the pressure applied when the electric power cable is drawn in can be reduced So that wear and deforming of the shape are prevented and reuse is possible.
