Abstract

The invention discloses a method for monitoring the insulation state of epoxy resin insulating media in a sulfur hexafluoride electrical device. The method comprises the steps of (1) acquiring a gas sample, wherein gas in the sulfur hexafluoride electrical device is acquired to serve as a sample to be detected; (2) detection, wherein the sample to be detected is detected with the gas chromatography, the gas-chromatography-mass spectrometry or the infrared spectroscopy to obtain analysis data of COS in the sample to be detected; (3) comparing the analysis data obtained from the step (2) with standard data of COS so that qualification and quantification of COS in the sulfur hexafluoride electrical device can be achieved and the insulation state of the epoxy resin insulating media in the sulfur hexafluoride electrical device can be judged. With COS serving as characteristic gas, whether solid insulating media, including basin-type insulators, of epoxy resin in the SF[6] electrical device are subjected to discharge erosion can be judged accurately.

Description

technical field

[0001] The invention relates to a method for monitoring the insulation state of electrical equipment, in particular to sulfur hexafluoride (SF 6 ) Monitoring method of insulation state of epoxy resin insulation medium in electrical equipment. Background technique

[0002] Sulfur hexafluoride (SF 6 ) The pot insulators and other epoxy resin insulating media widely used in electrical equipment will be irreversibly damaged once they are discharged, which will eventually cause insulation breakdown and cause serious power system operation accidents. Therefore, it is necessary to find an effective monitoring method for SF 6 Potty insulators in electrical equipment and other methods involving the insulation state of epoxy resin insulation media.

[0003] Traditional for SF 6 The monitoring methods for the insulation state of electrical equipment include electrical methods and chemical composition analysis methods. The UHF method (UHF), the most widely used elec...
