Embodiment Construction

[0027] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0028] like figure 1 As shown, an outdoor 500 kV HGIS power distribution device structure according to the present invention includes HGIS equipment and frame components. The HGIS equipment includes three sets of circuit breaker units and four sets of bushings. The circuit breakers and bushings are located on the same axis superior. The arrangement of circuit breakers is consistent with the conventional HGIS scheme, that is, the three groups of circuit breakers are arranged in the order of "incoming circuit breaker 1-internal circuit breaker 2-outgoing circuit breaker 3", and the arrangement of bushings is different from the conventional scheme. The detailed electrical connection schematic is shown in figure 2 shown.

Abstract

The invention relates to an outdoor 500kV HGIS power distribution device structure and solves a disadvantage that practical demands can not be satisfied by an HGIS equipment arrangement structure in the prior art. The outdoor 500kV HGIS power distribution device structure comprises the HGIS equipment and a framework assembly, wherein the HGIS equipment comprises an incoming wire breaker, a middle breaker and an outgoing wire breaker which are sequentially and linearly arranged, a first end of the incoming wire breaker is equipped with an incoming wire casing, a tail end of the incoming wire breaker is equipped with a first bus casing, a first end of the middle breaker is connected in parallel with the first end of the incoming wire breaker through a branch bus, a tail end of the middle breaker is equipped with an outgoing wire casing, a first end of the outgoing wire breaker is connected in parallel with the tail end of the middle breaker, and a tail end of the outgoing wire breaker is equipped with a second bus casing. According to the outdoor 500kV HGIS power distribution device structure, not only can a vertical dimension of a 500kV HGIS power distribution device be effectively compressed, incoming / outgoing wire leading modes are optimized, and the framework and crossbeam arrangement structures are simplified.

Description

technical field [0001] The invention relates to the technical field of HGIS equipment, in particular to an outdoor 500 kV HGIS power distribution device structure. Background technique [0002] At present, the application of high-voltage electrical equipment in 500 kV substations in my country can be divided into three types: one is open electrical equipment (AIS), which is cheap and widely used. The disadvantage is that the power distribution device occupies a large area and the equipment failure rate High, the maintenance workload of the substation is heavy; the other is a fully enclosed gas-insulated combined electrical appliance (GIS), which can save a lot of space and improve operational reliability, but the equipment is expensive, and the impact of power outages during project expansion is greater. It is usually used in places where the land is particularly limited; the third type is HGIS equipment, which is basically the same in structure as GIS equipment, the differenc...
