Canister in, it has good insulating properties, is widely used in high voltage power transmisson system.GIS is almost all of to be cut-off,
Measuring and excess voltage preventer is all sealed in pressure vessel, device interior is the most subjected to the atmosphere, and use
SF6 gas medium insulating properties and arc extinction performance are excellent, and therefore GIS has that reliable height, maintenance work be little, the time between overhauls(TBO)
The feature such as longer.Although but GIS operational reliability is the highest, and the GIS overall operation feelings that in-site installation puts into operation
Condition is good, but owing to GIS is totally enclosed combined electric appliance equipment, once has accident to occur, can be than general separate type
The equipment of opening wide causes even more serious consequence, and breakdown maintenance will be extremely complex, and repair time is long, and repair process is up to two
More than week.
GIS have an accident the many main cause of comparison be certain burr occurs in the mill, install in parts occur loosening, internal
Dirt or inside have what numerous reasons such as defect caused to have metal impurities, insulator surface to occur.When these problems occur,
Under environment under high pressure, device interior often shows as shelf depreciation, discharges in various degree and for a long time under conditions of existing, and it is potential
Defect result in shelf depreciation and constantly occur, apparatus insulated performance also and then will progressively deteriorate and expand, and ultimately result in whole
Apparatus insulated environment is breakdown, so will largely threaten the safe operation of GIS, thus causes equipment fault and have a power failure,
Bring about great losses.Along with the application in power system of the switchgears such as GIS is more and more extensive, its safe and stable operation pair
Stablizing of safeguards system is most important.Partial Discharge Detection is to grasp GIS internal operation situation, finds that potential insulation lacks in time
The effective method of one fallen into, also by Partial Discharge Detection can be classified to internal flaw and identify, contributes to existing
Accident GIS is analyzed by field.
For GIS partial discharge detection method many employings superfrequency and ultrasonic Detection Method, have developed multiple GIS both at home and abroad
On-the-spot Partial Discharge Detection equipment, presently used detection device Host build is relatively big, detection sensor by signal transmssion line with
Main frame is connected, the detection of superfrequency to be carried out when GIS device carries out live detection, ultrasonic signal to be carried out
Detection, in order to machine operation is judged more accurately.Superfrequency detection is different with ultrasound detection principle, uses not
The position being positioned on GIS in same detection sensor, and detection also differs.The layout of each area GIS is different,
Need to face during detection and climb, sensor is stretched to the various operations such as distant place.Invention is had to propose at present a kind of portable
Multi-functional Partial Discharge Detection detection bar, fixes partial discharge detecting sensor in GIS detects, and this detection bar is by can
Telescopic insulating bar, sensor fastening device, amplifier fixed bin etc. form, and both can install sonac and also can install extra-high
Frequently, it is achieved a bar is dual-purpose.
