Abstract
A high-voltage bushing has an insulator, which contains an insulating gas and an insulating solid, and an inner conductor which is led through the insulator. A mounting flange is employed for the mounting of the high-voltage bushing on a wall. A sensor, which is arranged on the mounting flange and is configured for the detection of at least one reaction product of the insulating gas and/or of the insulating solid. A corresponding method monitors an operating state of the high-voltage bushing.
Claims8
A high-voltage bushing, comprising:
- an insulator having an insulating gas and an insulating solid;
- an inner conductor being led through said insulator;
- a mounting flange;
- and
- a sensor disposed on said mounting flange and configured for a detection of at least one reaction product of said insulating gas and/or of said insulating solid, wherein said at least one reaction product consists of at least one gas selected from the group consisting of:
- SO2, H2, CH4, CO and CO2.
A method for monitoring an operating state of a high-voltage bushing having an insulator with an insulating gas and an insulating solid, an inner conductor which is led through the insulator, a mounting flange, and a sensor, which comprises the steps of:
- detecting, by means of the sensor being disposed on the mounting flange, at least one reaction product of the insulating gas and/or of the insulating solid, wherein, for a detection of the reaction product, extracting a gas sample from a gas compartment of the insulator and feeding the gas sample to the sensor;
- and
- generating and evaluating a measuring signal.
