Embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1-3, the 72.5kV compound combined electrical equipment is the new product of developing on the basis of AIS and GIS rich experiences.It is assembled into a function combinations unit with circuit breaker CB, isolating switch DS, the modules such as earthed switch ES, current transformer CT of conventional air insulated switching installation, satisfies required function to guarantee best-of-breed functionality at interval by the modularized design of limited quantity.Main feature is in compactedness and modularized design (maximum characteristics do not need bus).The compactness of its existing GIS, reliability height, the few maintenance have the characteristics of AIS flexible arrangement again.Its modularized design can guarantee to realize all transformer station's arrangement requirement, more have simultaneously on-the-spotly install simply, characteristics efficiently.
Fig. 1 is general AIS transformer station's turnover line winding diagram at interval, and frame of broken lines inside is divided into the electric equipment that available compound combined electrical equipment replaces.From the graph as can be seen, its circuit breaker of general A IS transformer station (CB), current transformer (CT), isolating switch (DS), earthed switch (ES) are separate electric equipment, also relative safe distance to be arranged between two equipment, so these several occupation area of equipment are very big, and compound combined electrical equipment is developed new electric equipment again for substituting above-mentioned several equipment just, can play the effect of above-mentioned several electric equipments with an equipment, save land resource greatly.
State when Fig. 2 is the work of each element in the combined type high pressure combined electrical apparatus (TGIS).In addition, combined type high pressure combined electrical apparatus is compared with traditional AIS transformer station and is also had more advantage:
1.TGIS the high-tension apparatus floor space is little: it saves 80% space than AIS transformer station, because AIS is by air-insulated, the TGIS high-tension apparatus then is by the SF6 gas-insulated, and the user only need to do the installation basis of a transformer just passable, 72.5kV compound combined electrical equipment is directly installed on the underframe of transformer, floor space will significantly reduce.
2. non-maintaining: the TGIS high-tension apparatus has absorbed the GIS mature technique, has just saved the work that AIS needs periodic maintenance comparatively speaking.
3.TGIS high-tension apparatus power consumption is little: utilize transformer station that the compound combined electrical equipment technology builds to compare with traditional AIS transformer station, the energy loss performance can be ignored.
4.TGIS high-tension apparatus is installed, it is convenient to change: general only the installation needs more than 4 hour, and compound combined electrical equipment can split into single parts in addition, and 84% can reclaim, and compound combined electrical equipment oil-containing not, energy-saving and environmental protection.Advocating electric power system energetically for country does not have the oiling construction, and this is undoubtedly a kind of reasonable product.
So from these advantages of TGIS high-tension apparatus, it had both absorbed GIS and AIS
The successful operation experience, solved AIS because area is excessive in the problems that transform at old station and newly-built transformer station brings, and more can meet and reduce investment, save energy and reduce the cost and environmental requirement.From the development trend of international, domestic transformer station, utilizing the TGIS high-tension apparatus is the selection an of the best to the transformation and the construction of transformer station.
72.5kV compound combined electrical equipment is formed (also can according to requiring to add voltage transformer pt and lightning arrester LA module) by insulator, three station isolation-earthed switches (DES), current transformer (CT), circuit breaker (CB) module.Each unit is by modularized design, add each module and all design unified interface, the difference in functionality module can be assembled into fast a bigger function combinations unit (being compound combined electrical equipment) by unified interface, directly close by the paint sleeve pipe at last and be connected and be placed in the transformer top with 72.5kV transformer inlet wire side seal.The final TGIS function that realizes design.
Each parts all is independent parts, is connected with spring touch finger by conductor to be integrated in the airtight SF6 air chamber, and SF6 gas can guarantee the insulating requirements of each electric device.
The circuit breaker operating principle: circuit breaker drives branch, the closing operation that sequence number 9 breaker operator pull bars are controlled circuit breaker by the spring mechanism of outside.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
