Problems solved by technology
In this case, as described in Patent Document 1, since conventional detection electrodes are usually made of metal plates such as stainless steel or aluminum, in order to ensure the mechanical strength against vibration, the plate thickness is made thicker, and the plate thickness becomes thicker. Then the weight increases, and the supporting structure for supporting it also increases in size, and as a result, the sensor also increases in size
In addition, the number of parts used to fix the detection electrode will inevitably increase, and performance may vary due to dimensional tolerances.

Embodiment Construction
[0022] In the present invention, the so-called gas-insulated electrical equipment refers to equipment having more than one gas-insulated busbar and more than one gas-insulated electrical device, such as gas circuit breakers, gas-insulated circuit breakers, gas-insulated transformers, etc., including, for example, their Various GIS (gas insulated switchgear, etc.) for collective use. In addition, the gas-insulated electrical equipment of the present invention also refers to the gas-insulated electrical device and the partial discharge detection sensor provided in the recess of the probe hole of the above-mentioned insulated bus bar. In addition, the above-mentioned partial discharge detection sensor may be always connected to the coaxial cable, or may be connected through a connector only when necessary. The coaxial cable transmits the voltage induced by the electromagnetic wave detected by the conductive film to the measuring device after being amplified by the amplifier.

Abstract
The present invention relates to a partial discharge detection sensor, a partial discharge detection device and a gas insulating electric facility with the partial discharge detection sensor. The present invention provides a partial discharge detection sensor with simplified structure, small size and light weight and a gas insulating electric facility which is equipped with such a sensor. The partial discharge detection sensor is characterized by being provided with an insulative base plate, a conductive film which is integrated with the insulative base plate as a whole by combining or bonding, a terminal which is in electric connection with the conductive film, a conductor which ensures that the terminal is in electric connection with the conductive film and a flange which supports the insulative base plate. The gas insulating electric facility is characterized by being provided with a gas insulating generatrix and the sensor. The gas insulating generatrix is provided with a high voltage conductor which is supported by an insulative support part inside a metal vessel which is encapsulated with insulative gas and a probe hole part with a concave part which is arranged inside the metal vessel.
Description
technical field [0001] The present invention relates to the detection of sulfur hexafluoride (SF 6 ) gas and other insulating gases sealed in metal containers for partial discharge sensors of gas-insulated electrical equipment used, partial discharge detection devices and gas-insulated electrical equipment, especially related to gas-insulated electrical equipment with a partial discharge detection function caused by insulation abnormalities . Background technique [0002] Gas-insulated switchgear, gas-insulated transformers, etc., and gas-insulated busbars are sealed with SF 6 The structure of fixed and movable contacts, coils, high-voltage conductors, etc. is insulated to support the metal container of insulating gas. [0003] These gas-insulated electrical equipment often cause partial discharge when a high-voltage electric field is applied due to internal abnormalities such as foreign matter mixed in the metal container, protrusions formed on the high-voltage conductor,...
