Description
Technical field
The present invention relates to transformer station's technical field of electrical power trans mission/distribution system, particularly a binary box-type substation.
Background technology
For adapting to the development of electric power system urbanization, high voltage substation needs miniaturization and can factory's complete production.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 in a protection against the tide, antirust, dust-proof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, moveable steel construction casing, electromechanical integration, totally-enclosed operation, be specially adapted to urban network construction and upgradation, a kind of brand-new transformer station emerged after Shi Ji civil engineering transformer station.This is not only conducive to the requirement of building a station selecting load center at existing city high load capacity density region, is also conducive to urban network reconstruction, reduces step-down level, simplifies wiring, significantly reduces electric energy loss.Box-type substation is applicable to residential quarters, city public transformer, bustling downtown area, construction power supply etc., and user can select box change according to different service conditions, load level.
