Description
Technical field
The present invention relates to sensor technology, belong to high-tension switch gear Hidden fault diagnostic techniques field, particularly a kind of sensor support device for GIS device superfrequency shelf depreciation live detection.
Background technology
Along with the widespread use of China's gas-insulated combined switch (hereinafter referred to as GIS) equipment in electrical network, its importance in electric system becomes increasingly conspicuous, GIS breaks down and forms huge threat by power system security, have a strong impact on the stability of power supply, light then cause economic loss, heavy then cause large-area power-cuts, harm social stability and safety, therefore must be paid much attention to the operation conditions of GIS, be reduced GIS fault odds as far as possible.Although GIS device reliability of operation is higher than common electrical equipment, but it is in operation and still there will be more accident, insulate in GIS fault, cut-off and close, external force and other three classes defect account for more than 80% of total breakdown, the reason of these faults is caused to be divided into manufacture, install and other reason three class, metal particle residual in manufacture and powder etc. all likely cause GIS fault, scratch in installation process, the foreign material invaded, moisture, misloading and neglected loading also likely cause conductor when running overheated, flashover or even the accident such as to puncture, it is improper that other failure cause comprises design, maloperation and outside destroy etc.
Operating experience shows, GIS, before generation electric fault, shelf depreciation (hereinafter referred to as PD) can occur mostly, and PD causes insulating medium part to puncture produced electric discharge because internal field in GIS concentrates.GIS inside inevitably also exists various insulation defect, and these defects have distorted the electric field around it, at some position, electric field is greatly enhanced, so that exceeded the breakdown field strength of insulating medium, thus caused PD to occur, PD long-run development just may cause serious insulation fault.PD is the sign of insulation degradation on the one hand, by carrying out to GIS device the insulation status that PD live detection can learn GIS, thus provide reference frame for the maintenance of GIS, the generation of prevention and prevention major accident, on the other hand, PD is also the major reason causing insulation degradation, must be paid attention to, detect the PD in GIS, to ensureing that the safe and reliable operation of GIS has important practical significance.
Therefore, State Grid Corporation of China is according to technical manual files such as " Q/GDW1168-2013 power transmission and transformation equipment state overhauling testing regulations " " Q/GDW11059-2013 Cubicle Gas-Insulated Switchgear shelf depreciation live testing technology rig-site utilization directive/guide " " Q/CSQ11401-2010 gas-insulated metal enclosed switchgear (GIS) UHF Detection for Partial Discharge specification charged electric power apparatus inspection specifications (trying)-2010 " " converting equipment live detection job guide suggestions-2014 ", regulation carries out a superfrequency shelf depreciation live detection for 550kV (363kV) and above GIS device half a year, 252kV and following electric pressure equipment carry out a superfrequency shelf depreciation live detection for 1 year.
For guaranteeing safety detection, particularly guaranteeing personal safety and device security, except strict implement electric power relevant safety standard and security regulations, also requiring that what time following attention is: when (1) is detected, should not touch other charging equipment dynamic; (2) prevent sensor from falling on GIS pipeline, avoid having an accident; (3), when using sensor in small space, health should be avoided to touch GIS pipeline as far as possible; (4) when detecting, prevent from touching other parts of malfunction GIS by mistake; (5) when using sensor to detect, should insulating glove be worn, avoid the direct feeler metal parts of hand.But GIS device compact conformation at present, detection space is narrow and small, and some measuring point height is more than 3m even 5m, and in actual mechanical process, testing crew limbs can touch GIS device unavoidably, buries the person and device security hidden danger.
Summary of the invention
