Description

{SAFETY DIAGNOSIS EQUIPMENT OF UNDERGROUND CABLE}

More particularly, the present invention relates to a safety diagnostic apparatus for a substation cable for substation and distribution, and more particularly, to a safety diagnosis apparatus for a substation cable which is capable of horizontally laying a ground cable in real time on a ground, cooling the substation cable, The present invention relates to a safety diagnosis apparatus for an underground cable for substation and distribution.

Since 1973, KEPCO has been working on the underground wiring project to improve electric power supply capacity, prevent accidents caused by natural disasters and improve the beauty and minimize the harmful electromagnetic wave caused by high voltage lines. (NDIS). However, it is only a matter of grasping the status of the facilities of the processing line and the underground distribution line, and the countermeasure against the accident by the underground distribution line is insufficient.

Currently, electric and electric fire accidents occur frequently in the underground distribution line due to defects of the distribution line itself, disconnection due to excavation work, damage due to overcurrent, and defective connection.

Therefore, KEPCO is monitoring the excavation site through the jurisdiction area of the Yongyuan Circle as part of the excavation work to prevent trauma to the underground distribution line during the excavation work. If there is an abnormality in the underground distribution line, an automatic switchgear We are dealing with accidents in a way that cuts off the power supply and dispatches them on site.

However, such a management method is incapable of real-time recognition of an accident and quick response thereto, and further, there is a problem that the aforementioned thief power can not be detected.

This prior art technique can not remotely monitor the state of the underground wiring and can not change the state of the case variably in the ground to maintain the normal state for a period of time from repair to maintenance, There is a problem that the position is changed or changed.

The configuration of the case portion is as follows.

Here, the upper case is pointed upward, and when the case part is moved upward in the ground made of soil by the rotation operation of the position adjusting part, which will be described later, the upward movement can be facilitated.

The position adjusting unit 200 includes a plurality of rotating bodies 210 connected to the four corners of the case 100 through a hinge end H so as to be vertically rotatable, A plurality of rotation motors 220 for receiving the control signals from the safety diagnosis unit 400 and rotating each of the plurality of rotating bodies 210; And a pair of fixed cylinders 230 installed on the rotary bodies 210 of the rotary body 210 for projecting and inserting the screws 231 into both sides of the rotary body 210.

The safety diagnosis unit 400 includes a horizontal sensor 410 installed in the case unit 100 for sensing the horizontal state of the case unit 100 and a horizontal sensor 410 for detecting a horizontal state of the case unit 100 from the horizontal sensor 410.
