Background technology
Gas-insulated metal closed power transmission line (GIL:Gas Insulated Metal Enclosed Transmission Line) is as a kind of employing SF
6Gas or SF
6And N
2The novel transmission line of electricity of mixed gas insulation, shell and guide rod coaxial arrangement, have transmission line capability big, take up an area of less, the reliability height, non-maintaining, the life-span long, with advantages such as environmental interaction is little.The research and development of this technology start from the sixties in 20th century, and purpose is to realize the underground transmission circuit suitable with the overhead transmission line transmission line capability.The High Voltage Power Corporation company of predecessor of U.S. CGIT Systems.Inc. company 1972 in N.J. Hudson Installation in Plant first in the world GIL, so far still at reliability service.
Most paragraphs of high voltage transmission line adopt open wire line form, but owing to transformer station's (comprising current conversion station) position, the circuit reason of aspect such as landform, circuit land used on the way, the transmission line of electricity corridor are chosen, designed also and have higher requirement.The technical advantage of GIL, make the transmission line of electricity that can solve special climate, particular surroundings and special location behind its alternative overhead transmission line or the high-tension cable set up problem, by making rational planning for and designing, not only can significantly reduce system cost, and can improve system reliability.According to the GIS of the council of IEEE/PES transformer station (gas-insulated metal-enclosed combined electrical apparatus) subcommittee statistics in 2004, global 73-1200kV gas-insulated transmission line always is about 198km.Up to now, the GIL that uses in the worldwide exchanges GIL, does not see the application report of direct current GIL as yet, and extra-high-voltage alternating current GIL also has only U.S. CGIT Systems.Inc. company that the product of moulding is arranged.In recent years, the developing rapidly of extra-high-voltage alternating current and extra-high voltage direct-current transmission engineering proposed requirement to the application of extra-high-voltage alternating current and extra-high voltage direct-current GIL.Insulation size for appropriate design extra-high voltage alternating current-direct current GIL, optimize the profile and the structural parameters of insulator, and the extra-high-voltage alternating current and the extra-high voltage direct-current GIL circuit of design carried out high voltage and the charged examination down of big electric current, need develop and can be used for GIL large scale concentric cylinder SF under extra-high voltage alternating current-direct current GIL elementary section high voltage and the charged examination of electric current greatly, the extra-high voltage alternating current-direct current
6Gap insulation attribute testing and the extra-high voltage alternating current-direct current GIL device of insulator arc-over attribute testing.
Be research SF
6The alternating current-direct current gas insulated metal enclosed combined electrical apparatus (GIS:Gas Insulated Switchgear) of gas-insulated characteristic and design excellent insulation performance and exchange GIL, domestic and international how tame correlative study mechanism and Utilities Electric Co. have designed and have been used for SF
6The container or the device of gas-insulated test, but all there are weak point in these test units or container, can't satisfy the needs of charged examination and the correlation test research of extra-high voltage alternating current-direct current GIL.As the diameter 2m of W.Boeck research group of Univ Munich Germany design, the large-scale vertical SF of long 5m
6Gas-insulated test chamber, cumulative volume are 17m
3, this device can only carry out the experimental study of GIL related electrode gap and insulator, can't dock with the GIL elementary section to carry out charged examination.Kansai Electric Power Co. then directly adopts not improved GIS bus section, busbar section to carry out GIL and GIS insulator arc-over attribute testing, but this device adopts an end to introduce high-tension structure, can't carry out the examination of big electric current to the GIL elementary section.The researcher of masschusetts, u.s.a science and engineering technical college has designed the SF of coaxial horizontal positioned
6The Insulation Test device can carry out concentric cylinder SF
6Gas gap insulation characterisitic test, but can't lay the disc insulator line correlation test of going forward side by side; Because this device adopts electrostatic accelerator to produce the form of high direct voltage, though can be to the charged examination under the extra-high voltage direct-current GIL elementary section high voltage, but can't carry out charged examination under the high voltage to extra-high-voltage alternating current GIL elementary section, this device one end is introduced high-tension structure simultaneously, also can't carry out the examination of big electric current to extra-high voltage alternating current-direct current GIL elementary section.Application number is that 200810112990.2 Chinese invention patent discloses a kind of experimental study device that is used for DC gas insulated metal enclosed transmission line of electricity (GIL), and this device can be used for SF
6Gas gap insulation characterisitic, insulator surface flashover characteristics and metallic conducting particle test, but a this end is introduced the electric current examination that high-tension structure can't be carried out the GIL elementary section, and because plant bulk is little, the electric pressure that bushing can tolerate is low, can't carry out large scale concentric cylinder SF under the extra-high voltage alternating current-direct current
6Gas gap and the extra-high voltage alternating current-direct current GIL experimental study of insulator.
In sum, there is not to satisfy simultaneously charged examination under extra-high-voltage alternating current and the extra-high voltage direct-current GIL elementary section high-voltage large current at present both at home and abroad, extra-high-voltage alternating current and extra-high voltage direct-current GIL large scale concentric cylinder SF
6The test of gas gap insulation characterisitic, the device that extra-high-voltage alternating current and extra-high voltage direct-current GIL test with support insulator and disc insulator flashover property.What existing test unit had only can be used for SF
6The test of gas gap insulation characterisitic and insulator arc-over characteristic can not be used for the charged examination of GIL elementary section; What have only can be used for charged examination under the GIL elementary section high voltage and can not be used for charged examination under the big electric current of GIL; The electric pressure that the voltage that has can tolerate is low can't to satisfy extra-high voltage alternating current-direct current GIL large scale concentric cylinder SF
