More particularly, the present invention relates to a cable connection point deterioration detection system and a control method of a cable connection point deterioration detection system capable of detecting deterioration of a cable connection point remotely, and more particularly, to a control method of a cable connection point deterioration detection system will be.

High voltage cables are used to connect process equipment where high voltage is used or connections between transformers to which high voltage is applied. In this case, the connection point between the high-voltage cables or the connection point between the factory equipment and the cable is referred to as a connection point. The connection point of the high-voltage cable is deteriorated by thermal or mechanical stress due to continuous operation. There is a case where the insulation breaks down in the case of the above.

The insulation breakdown process at the high voltage cable connection point will be described in more detail with reference to FIG.

1 is a view showing an insulation breakdown process at a connection point of a high voltage cable. First, as shown in FIG. 1A, when thermal or mechanical stress is applied to a connection point of a high voltage cable, an electric tree is generated due to partial electric field concentration inside a connection point of the high voltage cable, Voids or cavities are formed in the insulator at the connection point of the high voltage cable due to the electric tree, resulting in nonuniformity of the insulator. Partial discharge occurs in the connection point of the high voltage cable due to the nonuniformity of the insulator, so that the insulation at the high voltage cable connection point is broken as shown in FIG. 1C.

Here, the partial discharge means a partial gas insulation breakdown phenomenon that occurs due to local concentration of an electric field locally on a void inside the insulator under a high electric field, as shown in FIG.

Therefore, in order to determine whether or not the deterioration at the high-voltage cable connection point is deteriorated, it is necessary to continuously detect the deterioration state of the high-voltage cable connection point by detecting the occurrence of the partial discharge at the high-voltage cable connection point.

An example of a device for detecting a partial discharge in a cable is disclosed in Korean Patent Laid-Open Nos. 10-2004- 0079050 and Korean Patent Registration No. 10-07924530. However, the partial discharge detecting device in the cable according to the prior art, including Korean Patent Laid-Open Patent Application No. 2004 ?? 0079050 and Korean Patent No. 10 ?? 0724530, detects a partial discharge at a cable connection point from a remote location in real time I could not.

In order to detect the partial discharge at the cable connection point remotely in real time, the partial discharge detection device must be operated in a condition that it is always connected to the cable. To this end, a separate power line cable for supplying the control power to the partial discharge detection device In addition, when the partial discharge detecting device is provided for each connection point of the cable, there is a problem that the power line cable to be installed in order to supply the control power to each partial discharge detecting device becomes long.

 Further, since the voltage drop occurs when the length of the power line cable for supplying the control power to the partial discharge detecting device becomes longer, the voltage is increased to a voltage higher than the voltage required by the partial discharge detecting device, There is a problem that electric power is wasted.
