More particularly, the present invention relates to an installation for repairing a submarine cable failure, and more particularly, to a submarine cable failure repairing apparatus for a submarine cable, To a cable underground cable fault recovery apparatus capable of restoring a cable by forcibly connecting the ground cable.

In recent years, due to the development of information and communication technology, the load of using electric power has been rapidly increasing. Accordingly, there is a growing demand for high quality of electric power and high reliability of electric power supply.

The distribution automation system optimizes the operation of the system by collecting data through the control terminal for distribution automation installed on the distribution line and monitoring the distribution line, and when the distribution line failure occurs, the control terminal for distribution automation at each branch Detect the fault and identify the fault occurrence.

In addition, when the fault section is detected, the distribution automation system can isolate the fault section and flex the load by using a nearby distribution line, thereby restoring the fault section and minimizing the power failure. This contributes to the improvement of reliability.

However, in the conventional power distribution automation system, the reference current value is set, and when the overcurrent exceeding the reference current value is detected, the failure is detected by detecting the failure. The reference current value itself for detecting the failure is set to be erroneous In particular, when the reference current value is set to be higher than the normal value, if a failure occurs below the reference current value, there is a problem that the failure detection itself is impossible at all.

In addition, there has been a problem in that it is only possible to detect a fault and move to a position where a fault has occurred, which can not be solved.
