Oil-gas casing direct connection arrangement transform the remodeling method of pipe mother's connected mode as.Belong to T ＆ D Technology field.
Background technology：
Because nearby building the projects such as subway, CBD centers and east station, underground water is largely extracted out, so as to cause for GIS transformer stations
Transformer substation foundation is settled.Because the station uses GIS to be connected by oil-gas casing direct connection arrangement with transformer, because
Respective ground load is different, and the amplitude of sedimentation is also inconsistent, so as to cause GIS and transformer high-voltage and the direct interface of middle pressure
Very big destructive power will be born, for the operation safety of transformer station, transformer is changed with GIS by oil-gas casing direct connection arrangement
It is the connected mode of pipe bus to make.Domestic power transmission and transformation Lixing industry passes through oil-gas casing direct connection for GIS substation transformers and GIS
Arrangement transform the installation of flexible circuit conductor as and reforming technology flow was originally：1st, gas recovery, removes oil-gas casing and transformer
To GIS bus pipe bus bar canisters, bus bar canister basis is removed；2nd, portal frame foundation construction；3rd, portal frame is installed；4th, casing air peace
Dress；5th, the installation of flexible circuit conductor and wire holding equipment.
, in the connection transformation operation of transformer oil gas bushing is carried out, there is larger restricted, erection in process above flow
Portal frame, it is necessary to portal frame basis could be rebuild after first removing transformer to GIS bus bar canisters and its basis, then dragon is set up again
Door frame, finally carry out the installation of flexible circuit conductor, flexible circuit conductor and GIS dock and wire holding equipment adjustment, the engineering time is general
It is more long.Foregoing construction process, because of portal frame to be reconstructed basis, and sets up portal frame so that transformer station's power off time is more long, together
When also increase difficulty of construction, cause network system for a long time in abnormal running mode, seriously threaten power grid security.Not only
Itself construction cost is larger, while because of the long-term electricity sales amount decline for having a power failure and triggering, objectively having had influence on Zhengzhou City's energy scheduling.
And process above also has the following disadvantages：1) enforcement difficulty is big：Transformation region narrow field, arrangement portal frame base bits are equipped with
Limit.Portal frame is such as arranged, the dynamic and static load of portal frame is checked and bothered very much, will appear from structure type complicated foundation, because basis is attached
Basis is more in nearly old use, is highly detrimental to construction.And surrounding ground will be destroyed during new foundation construction, change ensuing
In making, Construction traffic will be unable to erect-position, be that follow-up work brings new problem.2) long construction period：It is with 220kV power distribution equipments
Example, after such as using portal frame reconstruction flow, transformer oil feed channel all to remove, could change to original equipment foundation of civil work
Make and civil engineering maintenance, set up again portal frame, flexible circuit conductor install and wire holding equipment adjustment etc. construction is accumulative about needs 42 days, apply
The work cycle is long, relatively costly.3) network system normal mode is had a strong impact on：Because 1# main transformer in shore is stopped transport, and plus in meeting kurtosis
The high load capacity energized period in summer, shore 1# becomes institute's on-load and is all undertaken down to shore 2# main transformers and osiery 1# main transformers, 2# main transformers, causes
Network system is in abnormal running mode for a long time, serious to threaten Zhengzhou eastern region power grid security.4) economic loss is big：
Under the influence of present financial crisis, last year is negative growth to city's electricity sales amount on year-on-year basis, in the critical period of summer peak meeting, Zhengzhou City east
The power supply safety in portion area is extremely important.And if now because riverfront change is chronically at a main transformer stoppage in transit, causing Zhengzhou electricity
Net is chronically under abnormal running mode, then certainly will largely effect on the power supply safety of Zhengzhou City, is not only difficult to complete state's household electrical appliances
The sale of electricity index that net company assigns, and Zheng Dong new districts normal development is hidden some dangers for.
