<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated voltage detection bushing which has a simple structure and easy assembly. <P>SOLUTION: On one end of an insulating tube 1, an applied-voltage side flange metal fitting 2 is fixed and, on the other end, a grounding-side flange metal fitting 3 is fixed, and a central conductor 4 disposed on the axial line of the insulating tube 1. A semi-conductive layer 5 formed out of a semi-conductor material having a surface resistivity of 105 to 108 on the outer surface of the insulating tube 1 is electrically connected with the applied-voltage side flange metal fitting 2. An electrode 6 electrically connected with the semi-conductor layer 5 is provided at or near the grounding-side flange metal fitting 3. Leaking current running through the semi-conductive layer 5 via the applied-voltage side flange metal fitting 2 can be detected from the central conductor 4. <P>COPYRIGHT: (C)2004,JPO</p> |
