Description
Technical field
The present invention relates to HGIS equipment technical field, specifically a kind of outdoor 500 kilovolts of HGIS power distribution device structures.
Background technology
The high-voltage electrical equipment applicable cases of China 500 KV substation can be divided into three kinds at present: one is open type electrical equipment (AIS), low cost, is widely used, and shortcoming is that power distribution equipment floor space is big, equipment failure rate is high, and station maintenance workload is big；Another is all-closed gas insulating combined electrical apparatus (GIS), saving by a relatively large margin can take up an area and improve operational reliability, but equipment manufacturing cost is expensive, and the impact that has a power failure during Enlargement engineering is relatively big, generally in the local use that land used is the most limited；The third is HGIS equipment, structure is essentially identical with GIS device, it is a difference in that bus uses external unlimited layout, its feature is between AIS and GIS device, there is the advantages such as floor space is little, operational reliability is high, convenient for installation and maintenance, enlarging power failure coverage is little, output investment ratio GIS is little, extensively applies at 500 KV distribution devices.
Patent No. 200920034787.8, the patent of entitled " a kind of power distribution device structure of outdoor HGIS equipment " propose a kind of HGIS arrangement, and it is all arranged in the inner side of HGIS unit into and out of thread casing, and bus casing is positioned at the two ends of HGIS.This technology mainly has following deficiency: 1, meet the requirement of electrical safety for controlling the distance between the downlead above thread casing, the Cantilever Beams of long 7 ~ 8 meters need to be installed on intermediate transverse girder, processing and complexity thereof, manufacture and assemble difficulty, waste steel, the most inharmonious with transformer station surrounding devices, organoleptic difference；2, line is both needed to be drawn by suspension insulator and cross-line, and wire, insulator chain consumption are very big, increases construction investment, and electrically installs loaded down with trivial details, construction period is significantly increased；3, being limited by bus to the restriction of electrical distance between downlead, line downlead, this arrangement form power distribution equipment longitudinal size is very big, fails to give full play to HGIS and saves the advantage taken up an area.
Patent No. 201420494186.6, the patent of entitled " new arrangement of hanging tubular mother's HGIS power distribution equipment " changes HGIS equipment arrangement, by the way of using branch bar switching, bus casing is arranged in centre position, enter, outlet casing tube is arranged in two ends, eliminate intermediate frame, crossbeam and line upper strata cross-line, have compressed power distribution equipment line framework longitudinal size, but equally exist many deficiencies: 1, this arrangement form 1M, 2M busbar arrangement is compact, immediately below middle chopper is arranged in, in the middle of the most any one during circuit breaker failure maintenance, it is both needed to make bus full cut-off, regional power grid power supply reliability is greatly reduced.2,1 layer of cross-line can only at most be arranged above this arrangement form bus, multi-direction double back side outlet cannot be realized, if applying in actual substation project, when line directly joins string, although transition can realize circuit and turn to by increasing by the way of circuit corner tower, but construction costs is significantly increased, less economical, when string is joined in outlet and side outlet, this arrangement form is difficult to, and generalization is poor.3, this arrangement form does not considers equipment conveying circuit, it is considered to 500 kilovolts of HGIS maximum lifting elements weight reach 8t, and the possible maximum lifting radius of equipment reaches 40m, and difficulty chosen by crane, the extremely difficult realization of equipment hoisting.4, when this arrangement form applies to 500 kilovoltage grade power distribution equipment, consider electrical distance verification, bus crossbeam span between line framework reaches 48m, it is computed, beam section at least needs to reach more than 2.5x2.5m could meet force request, not only wasting great deal of steel, outward appearance is also the most inharmonious with surrounding.5,500 kilovolts of branch bar cylinder quantity that each interval of this arrangement increases are about 90m, calculate by 1.5 ten thousand yuan/m, the each interval of this arrangement form more conventional HGIS arrangement increases installation cost 1,350,000 yuan, even if considering that compression floor space optimizes expense, economy is the most very poor.
Therefore, how to develop a kind of novel HGIS power distribution device structure form to have become as urgent need and solve the technical problem that.
