ULTRA-HIGH FREQUENCY PARTIAL DISCHARGE ARRAY SENSOR APPARATUS FOR HIGH-VOLTAGE POWER APPARATUS
First Claim
1. An ultra-high frequency partial discharge array sensor apparatus for a high-voltage power apparatus, comprising:
- a sensing unit which detects an electromagnetic wave partial discharge signal generated due to an internal defect of a high-voltage power apparatus and includes a plurality of sensors installed to detect information related to the position where the defect occurs;
an anti-surge filter unit which prevents a surge input from the sensing unit;
a signal delay time adjusting unit which equally adjusts delay times of signals input from the anti-surge filter unit;
a signal switching unit which selectively transmits or blocks signals input from the signal delay time adjusting unit;
a connector unit which connects a signal transmitted from the signal switching unit to the outside; and
a sensor body which has a receiving space.
