Abstract
The invention discloses a box type substation which comprises a box body and a top cover. The top cover comprises an eave top, a water blocking eave and a drain tank. A number of drain channels are arranged in the wall body of the box body. A water inlet of each drain channel is arranged in the drain tank. A water outlet of each drain channel is arranged at the bottom of the box body. When the box type substation provided by the invention is used, rain quickly flow into the drain tank along the eave top, come into the water inlets of the drain channels in the drain tank, flow into the drain channels located in the wall body of the box body, and finally discharge from the water outlets at the bottom of the box body. Through the structure, rain drops around the top cover are prevented, which makes servicing and maintenance in a rainy day convenient and improves the safety performance.
Description
Technical field
The invention belongs to transformer station's technical field, be specifically related to a kind of box-type substation.
Background technology
Box-type substation is a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment, by indoor, the outdoor close-coupled controller switching equipment of certain connection plan row's all-in-one-piece prefabrication, organically combine by functions such as high powered, transformer pressure-reducing, low-voltage distributions, be arranged on a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in steel construction casing, electromechanical integration, totally-enclosed operation, be specially adapted to city net construction and upgrading, a kind of brand-new transformer station emerging after Shi Ji civil engineering transformer station.Box-type substation has substituted original civil engineering power distribution room, power distribution station, become novel complete change power distribution equipment, be applicable to residential quarters, urban public change, bustling downtown area, construction power supply, mine, factory and enterprise, oil gas field and wind power station, user can select box change according to different service conditions, load level.Box-type substation, since coming out, has developed very rapidly, has accounted for 70% of distribution transformer at countries in Europe, and the U.S. has accounted for 90%.
For box-type substation, China is from 20 century 70 later stages, introduce and imitated box-type substation from the state such as French, German, adopt high-low voltage switch cabinet from structure, transformer composition mode, this case becomes and is called European-type box and becomes, Vivid analogy be to high-low voltage switch cabinet, transformer cover house.From the nineties in 20th century, China introduces U.S.'s box-type substation, and structurally by on-load switch, loop networks switch and fuse structure simplification are put into oil tank of transformer and be immersed in oil.Lightning arrester also adopts oil immersed type zinc oxide arrester.Transformer is cancelled conservator, and fuel tank and radiator are exposed in air, and this case change is called American-type box and becomes, and Vivid analogy is that transformer side hangs a chest.
Outer casing of box type transformer substation adopts steel plate or alloy sheets, is furnished with bi-layer tip cap, and thermal insulation is good.Shell and skeleton all pass through preservative treatment, have the condition of long-term outdoor use.Profile and color can be mutually harmonious with environment.Easy for installation, below the basis of box-type substation, be provided with cable vault, can enter cable vault and carry out work and be provided with manhole in low-pressure chamber.From volume, European-type box becomes because ordinary tap cabinet and transformer are installed in inside, and small product size is larger.American-type box becomes owing to adopting integrative installation technology small volume.
In order to meet different clients' demand, the structural change of existing box-type substation is more, and still, along with the expansion of purposes, its structure still has needs improvements badly.
