Background technology
Gas-insulated metal closed power transmission line (GIL:Gas Insulated Metal EnclosedTransmission Line) comes from SF
6The metal enclosed bus of insulation is a kind of employing SF
6Gas or SF
6And N
2The high voltage of mixed gas insulation, shell and conductor coaxial arrangement, high current power transmission equipment.Its electrical specification is similar to overhead transmission line, the naked problem of aging, and loss is low, and safety is good, and the occupation of land space is little, has advantage aspect the high capacity long distance powedr transmission.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.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.The longest GIL is in the Tokyo, total length 3.3km, rated voltage 275kV.
Because SF
6Gas has excellent insulation and arc extinction performance, is the best in the world present insulating medium, is widely used in the High-Voltage Electrical Appliances field.Gas-insulated metal closed power transmission line is as a kind of novel transmission line of electricity, have that transmission capacity is big, loss is little, component modelsization, take up an area of less, reliability is safe, non-maintaining, the life-span long, to advantages such as environmental impact are little, the employing of GIL, the transmission line of electricity that can solve special climate, particular surroundings and special location sets up problem, by making rational planning for and designing, not only system cost can be significantly reduced, and system reliability can be improved.Yet for a long time, influenced slowly by the direct current transportation technical development, the research at DC gas insulated metal enclosed transmission line of electricity (GIL) is very few specially both at home and abroad, does not form direct current GIL product.Up to now, the electric pressure scope of the interchange GIL in the worldwide is 73～1200kV.Insulating Design is the key technique of direct current GIL, comprises the selection of coaxial electrode clearance for insulation size, the design of benzvalene form and support insulator contour structures, and the inhibition of metallic conducting particle.For the good direct current GIL of design synthesis insulating property, need carry out a large amount of SF
6Gas gap Insulation Test, the test of insulator surface flashover characteristics and metallic conducting particle test.
Be research SF
6The alternating current-direct current gas insulated metal enclosed combined electrical apparatus (GIS) 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 there are many weak points in these test units or container when being used for direct current GIL Insulation Test.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, test each time all needs to fill a large amount of gas, charges and discharge gas during test and the gas purification workload is big; Single vertical air chamber makes the disc insulator can only horizontal positioned, can't carry out the test of metallic conducting particle to the influence of disc insulator insulating property.Kansai Electric Power Co. then directly adopts not improved GIS bus section, busbar section to carry out the disc insulator test, and this test unit can well carry out the insulator arc-over attribute testing, but is inconvenient to carry out various SF
6The insulation characterisitic test of gas gap and metallic conducting particle test.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
6Gap insulation test, but can't lay the disc insulator line correlation test of going forward side by side.Artificial research such as domestic professor Qiu Yuchang of Xi'an Communications University SF
6Gas-insulated characteristic and the insulator model carried out the measurement of surface charge has designed the SF of band extreme ultraviolet quartz window
6The gas-insulated test chamber can be observed ultraviolet light and visible light in the discharge process; But this test chamber also is the form that adopts vertical structure, is inconvenient to carry out the disc insulator correlation test.
In sum, there is not a kind of device that is specifically designed to direct current GIL Insulation Test at present both at home and abroad, relevant SF both at home and abroad
6Gas-insulated test unit or container, or only be fit to SF
6The test of gas gap insulation characterisitic, or the test of the correlation properties that only are suitable for insulating.Do not possess SF simultaneously
