Abstract
The mixed type power distribution equipment of a kind of GIS and H-GIS, it comprises A, B, C tri-single-phase transformers, three single-phase transformers connect main breaker by △ bus, main breaker connects 35kv or 66kv bus, switch branch loop connects 35kv or 66kv bus, and described 35kv/66kv bus and switch branch loop adopt H-GIS pattern; Main breaker, together with Δ busbar combination, adopts GIS pattern.Adopt the present invention of technique scheme, have the following advantages: (1) partition body equipment adopts H-GIS, easy access; (2) Δ bus and main breaker combine, and adopt GIS device, can effectively save floor occupying area; (3) Δ bus floor space is very little, and leak detection can be carried out together with main breaker GIS device, overcomes GIL in H-GIS+GIL scheme and needs the awkward shortcomings such as leak detection separately.
Description
Technical field
The present invention relates to a kind of side power distribution equipment, specifically relate to a kind of mode adopting GIS device to be combined with H-GIS equipment and arrange, for the technology of 500kV main transformer low-pressure side power distribution equipment equipment and △ bus.
Background technology
500kV transformer station of China adopts 550kV/220kV/35 (66) kV tertiary voltage, and low-pressure side access reactive power compensator is the important component part of transformer station.
At present in Substation Design, generally stress the design optimization of voltage levels, by optimizing wiring patterns, adopting compact device, compressing the measures such as power distribution equipment size, improve the reliability of transformer station, reduce floor space, reduce project cost.But initial thinking and pattern are still continued to main transformer low-pressure side, all adopt conventional equipment and ordinary distribution device, there is no obvious development and change for many years, floor space is very large, as adopted in the 500kV transformer station of compact device in high pressure side, the occupation of land of main transformer low-pressure side reaches 26 ~ 31% of the full station gross area.
Along with the high speed development of power grid construction, transformer station's scale and capacity increasing, the problem that main transformer low-pressure side equipment increases, floor space is large is also more and more outstanding.Because soil is non-renewable resources, be the fundamental state policy implementing Appropriate application soil further, conscientiously protect farmland, in the urgent need to carrying out the optimal design of main transformer low-pressure side.
When main transformer is single-phase change, low-pressure side need form △ winding, so time need the pattern considering △ bus.At present, main transformer low-pressure side, according to power distribution equipment pattern and bus pattern difference, has following 3 kinds of schemes.
(1) scheme one: GIS+ △ bus GIL
This programme main transformer low-pressure side power distribution equipment all adopts GIS pattern, and △ bus adopts GIL gas insulated bus pattern.
(2) scheme two: H-GIS+ △ bus GIL
This programme main transformer low-pressure side power distribution equipment all adopts H-GIS pattern, and △ bus adopts GIL gas insulated bus pattern.
(3) scheme three: H-GIS+ △ bus support type busbar
This programme main transformer low-pressure side power distribution equipment all adopts H-GIS pattern, and △ bus adopts support type busbar pattern.
Above-mentioned three schemes are low-pressure side layout pattern more conventional at present, but three kinds of schemes respectively have its weak point.
(1) scheme one adopts the mode of GIS+ △ bus GIL, although this layout pattern can save occupation of land, and maintenance and enlarging inconvenience.
(2) scheme two adopts the mode of H-GIS+ △ bus GIL, the maintenance of this layout pattern is convenient, but adopts separately the mode of GIL due to △ bus, is filled with sulfur hexafluoride gas in bus, need the equipment such as installing density monitor, make regular check on the situation that whether there is gas leakage.And △ bus GIL gas consumption is few, therefore, this mode uses inconvenience.
(3) scheme three adopts the mode of the conventional support type busbar of H-GIS+, and the advantage of this layout pattern is that maintenance is convenient, and does not need leak detection, but this mode △ bus significantly increases the floor space in low-pressure side region.
Summary of the invention
The object of this invention is to provide and a kind ofly not only to have saved floor occupying area, but also facilitate the mixed type power distribution equipment of GIS and H-GIS of operating maintenance.
For achieving the above object, the present invention is by the following technical solutions:
The utility model comprises A, B, C tri-single-phase transformers; three single-phase transformers connect main breaker by △ bus; main breaker connects 35kV or 66kV bus, and switch branch loop connects 35kV or 66kV bus, and described 35kV/66kV bus and switch branch loop adopt H-GIS pattern; Main breaker, together with △ busbar combination, adopts GIS pattern.
Described switch branch loop connects electric capacity duplexure and reactance duplexure respectively.
Adopt the present invention of technique scheme, have the following advantages: (1) partition body equipment adopts H-GIS, easy access; (2) △ bus and main breaker combine, and adopt GIS device, can effectively save floor occupying area; (3) △ bus floor space is very little, and leak detection can be carried out together with main breaker GIS device, overcomes GIL in H-GIS+GIL scheme and needs the awkward shortcomings such as leak detection separately.
As can be seen here, GIS and H-GIS mixed type power distribution equipment combines GIS+ △ bus GIL, the advantage of the conventional support type busbar of H-GIS+ △ bus GIL and H-GIS+ three kinds of schemes, overcome the deficiency of each scheme, be a kind of effective and feasible and economical and practical low-pressure side power distribution equipment arrangement simultaneously.
