Structural features
1. This product is composed of a high-voltage power distribution device, a transformer and a low-voltage power distribution device. It is divided into three functional compartments, namely a high-voltage room, a transformer room and a low-voltage room. The high- and low-voltage rooms are fully functional. The primary power supply system on the high-voltage side can be arranged into multiple power supply modes such as ring network power supply, terminal power supply, and dual power supply. It can also be equipped with high-voltage metering components to meet the requirements of high-voltage metering. The transformer room can choose S7, S9 and other low-loss oil-immersed transformers and dry-type transformers; the transformer room is equipped with a self-starting forced air cooling system and a lighting system. The low-voltage room can adopt a panel or cabinet-mounted structure to form the user's office according to user requirements. A power supply plan is required, with multiple functions such as power distribution, lighting distribution, reactive power compensation, electric energy metering, and power measurement to meet the different requirements of users, and facilitate the user's power supply management and improve the quality of power supply.
2. The high-pressure chamber has a compact and reasonable structure, and has a comprehensive anti-misoperation interlock function. The transformer can be provided with rails for easy entry and exit from the doors on both sides of the transformer room when the user requires it. Each room has an automatic lighting device. In addition, all components used in the high and low voltage rooms are reliable in performance, convenient in operation, safe and reliable in operation, and convenient in operation and maintenance.
3. Adopt natural general and forced ventilation to ensure good ventilation and cooling. The transformer room and the low-voltage room have ventilation ducts, and the exhaust fan has a temperature control device, which can automatically start and shut down according to the set temperature to ensure the full load operation of the transformer.
4. The box structure can prevent rainwater and dirt from entering and is made of special steel or aluminum alloy. After anti-corrosion treatment, it has the conditions for long-term outdoor use, ensuring anti-corrosion, waterproof, dust-proof performance, long service life, and beautiful appearance.
