Description
Technical field
The utility model relates to 500kV ehv power transmission engineering design technology field, more particularly, relates to a kind of 500kV HGIS power distribution equipment new arrangement structure of 3/2 breaker connection.
Background technology
500kV is as the electric pressure of the key electrical network of China's superhigh pressure, and the problems such as its technical advance obtain the concern of vast power industry designer.The Type of equipment that the 500kV outdoor power distribution unit of current China is conventional has four kinds, is respectively porcelain knob breaker, potting breaker, HGIS, GIS.
Because HGIS is in technology, advantage economically, obtained increasingly extensive application in recent years in China, HGIS has that operational reliability is high, adaptive capacity to environment strong, safeguard less, easy for installation, floor space is little, technical-economic index advantages of higher.
The conventional arrangement of 500kV HGIS power distribution equipment of 3/2 breaker connection is: bus adopts suspension type aluminum tube bus, in a complete string, the bus casing of HGIS is arranged in two ends, inlet-outlet sleeve is arranged in the inner side of bus casing, upright to line cross-line in HGIS location arrangements string on bus, by drawing to reach the standard grade interior to HGIS outlet casing tube and string line cross-line is connected.Due to the existence of line cross-line beam in the string of upper strata, need to arrange support column between two groups of buses.In addition according to two groups of inlet-outlet sleeves in string draw reach the standard grade difference time interruption maintenance and outlet casing tube draw the requirement of opposite side pipe bus electrical distance mutually of reaching the standard grade, cause the distance of the 2 groups of adjacent phases of bus in upper strata very large, be generally greater than 20m.
The conventional arrangement complex structure of 500kV HGIS power distribution equipment of 3/2 breaker connection, saving floor space aspect is compared with GIS or there is certain gap, for reducing the occupation of land of existing conventional 3/2 breaker connection 500kV HGIS power distribution equipment, simplify arrangement simultaneously, the utility model proposes a kind of brand-new arrangement.
Utility model content
The purpose of this utility model is to provide a kind of 500kV HGIS power distribution equipment arrangement of 3/2 novel breaker connection
For achieving the above object, the utility model provides a kind of 500kV HGIS power distribution equipment arrangement of 3/2 breaker connection, it is characterized in that: power distribution equipment framework adopts full co-ordinative construction, only bus girders is set, bus breaker unit, bus casing and network interconnecting circuit unit, inlet-outlet sleeve are arranged on two straight lines being parallel to each other, bus casing is arranged in the end of bus breaker unit, and inlet-outlet sleeve is arranged in the outside of bus casing; Each bus breaker unit and network interconnecting circuit unit respectively configure 1 current transformer and 1 isolating switch and earthed switch in the both sides of breaker fracture, arrangement is that circuit breaker is arranged in the bottom, current transformer is arranged in the top of circuit breaker, isolating switch and earthed switch and inlet-outlet sleeve branch bar are arranged in most top layer, the isolating switch of bus breaker unit and earthed switch are connecting side with network interconnecting circuit unit and circuit breaker is arranged vertically, and other isolating switches and earthed switch are all arranged in same straight line with circuit breaker; Adopt jumper pipe bus to connect between inlet-outlet sleeve and voltage transformer, arrange road below outgoing line side jumper pipe bus, arrange lightning arrester under the jumper pipe bus of main transformer inlet wire side, built on stilts line is connected with jumper pipe bus by built on stilts line downlead.
The utility model is by the position of adjustment HGIS bus casing, outlet casing tube and breaker unit, simplify power distribution equipment arrangement, cancel the upper strata cross-line beam of conventional H GIS power distribution equipment, reduce framework height, eliminate the intermediate frame post of conventional H GIS power distribution equipment bus girders, decrease the cross dimensions in line direction.
