Description
Technical field
The present invention relates to intelligent grid power transformation, distribution technique field, and in particular to one kind miniaturization preassembled transformer station.
Background technology
In recent years, with the expansion of socio-economic development and power system scale, country continues to increase power distribution network equipment water
Flat input, promote equipment lifting and scientific and technical innovation.According to《" 13 " industry development instruction-High-voltage Switchgear Industry, absolutely
Edge arrester industry, power capacitor industry》Disclose, in middle pressure field, research and development of products follows miniaturization, integrated, intelligent
Change, be highly reliable, few（Exempt from）Safeguard and environment-friendly principle, using the core devices and new technology of high technology content, new technology,
New material is developed, and achieves gratifying results.On the basis of constantly improve and raising existing product technology water product, successfully grind
Send out novel switched component and middle pressure C-GIS gas-filling cabinets, the solids such as composite insulating vacuum breaker, pole vacuum circuit breaker
The complete sets of products such as insulated switch cabinet and various Novel premounting transformer stations.
In the construction of Modern power distribution net, 10kV box-type substations are the important steps that user oriented is directly powered, and its is main
By members such as high-tension switch gear, power transformer, low voltage switch equipment, electric energy measuring equipment, reactive-load compensation equipment and connecting pieces
The complete set of distribution of part composition, these elements are prefabricated in factory and are assembled in one or several casings, for from 10kV
System conveys electric energy to 0.4kV systems.Box-type substation, mainly there is Europe to become and become with beautiful.Europe becomes because ordinary tap is installed in inside
Cabinet and transformer, small product size is larger, and investment is also larger, under the conditions of limited space, it is impossible to suit measures to local conditions to realize distribution construction
Demand.The simplification of on-load switch, loop networks switch and fuse structure is put into oil tank of transformer and is immersed in oil by U.S.'s change, though volume is relative
It is small, but without motor drive mechanism, distributing automation apparatus can not be set up, its heavy wool formula on-load switch does not meet the nothing of national Medium voltage switch or circuit breaker
Oiling policy.In addition, looped network scheme is not present in beautiful become, it is impossible to which fusion is in ring network power supply system very well；It is actual to build in application
The unshielded column phenomenon of equipment surrounding be present, it is impossible to eliminate external force and destroy and personal electric shock hidden danger.Above-mentioned have a series of technologies and ask
Topic not yet solves, and the lifting of power supply supportability and Urbanization Construction to power distribution network cause more serious influence.
In the prior art, Publication No. CN104917086A Chinese invention patent discloses a kind of using miniaturization mould
The outdoor preassembled transformer station of blockization design, including civil engineering part and electric part；Civil engineering part mostly uses prefabricated product,

Have a gravity assisted heat pipe, gravity assisted heat pipe built with hydraulic fluid, gravity assisted heat pipe it is closed at both ends, inside is in vacuum.The technical scheme
Ventilation and heat problem, but product design unreasonable structure are taken into full account, gravity assisted heat pipe on the inside of transformer locular wall with being welded on one
Rise, have potential safety hazard, maintenance is not easy.
Become in addition, Publication No. CN106532534A Chinese invention patent discloses a kind of cities and towns miniaturization prepackage type
Power station, including high-tension switch cabinet, distribution transformer and comprehensive intelligent distribution box, high-tension switch cabinet are arranged on distribution transformer；
Comprehensive intelligent distribution box is located at the side of distribution transformer and high-tension switch cabinet；Comprehensive intelligent distribution box is integral type casing knot
Structure, it is structure as a whole with distribution transformer by the way that bolt is detachably connected.Although the technical scheme is carried out to high-tension switch cabinet
Sealing, insulation, shielding design are safe for operation with equipment to guarantee personal safety, and low-pressure side is completed by comprehensive intelligent distribution box
The comprehensive function such as distribution and protection improves power supply reliability and the quality of power supply；The power distribution automation equipment and Intellisense of apolegamy are whole
End, the intelligent management and repair based on condition of component of transformer station can be achieved, but design structure still needs to improve, with adapt to current Urban Net Construction and
Transformation demand.
