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,wherein the sensing unit comprises a high sensitivity sensor disposed at a center thereof and a plurality of array sensors for position estimation disposed at regular intervals around the high sensitivity sensor,wherein the connector unit has a hermetically sealed structure in which a high sensitivity connector, an array sensor connector, and a signal switch connector which receives a switching command from the signal switching unit are installed outside the sensor body.
