1. This product is connected by a high-voltage distribution device, a transformer and a low-voltage distribution device, and is divided into three functional compartments, namely, a high-voltage room, a transformer room and a low-voltage room. High and low voltage room functions,high voltage side of the primary power supply system, can be arranged into a ring network power supply, terminal power supply, dual power supply and other power supply methods, can also beinstalled with high voltage metering device to meet the requirements of high voltage metering.Transformer room can choose S9, S11 series low loss oil immersed transformer and SC(B)9.SCR9, SC(B)10, SCR10 series dry type transformer; Transformer room is equipped with self-starting forced air cooling system and lighting system, low voltage room according to userrequirements using panel or cabinet structure to form the user needs power supply scheme, power distribution, lighting distribution, reactive power rate compensation, power metering and power measurement and other functions to meet the different requirements of users, and to facilitate the user's power supply management and improve the quality of power supply.
2, the high-voltage room structure is compact and reasonable, and has a comprehensive anti-misoperation of the "five" interlocking function. When the transformer is required by the user, therail can be set up to easily enter and exit from the two sides of the transformer room. Each room has automatic lighting device, in addition, all the components selected by the high and lowpressure chamber can be relied on, easy to operate, so that the product is safe and reliable, easy tooperate and maintain.
3, the use of natural ventilation and forced ventilation of two ways, so that the ventilation and cooling good. Transformer room and low pressure room have ventilation channels, exhaust fantemperature control device, according to the setting temperature can automatically start and close,to ensure that the transformer full load operation.
4, the box structure can prevent rain and dirt into the use of special steel plate or aluminum alloy plate production, anti-corrosion treatment, with long-term outdoor use of the strip. Ensure anti-corrosion, waterproof, dust-proof performance, long service life, and beautiful appearance.
