Product Structure Characteristics
●This product consists of a high-voltage distribution unit, a transformer and a low-voltage distribution unit, which is divided into three functional compartments, i.e., the high-voltage room, the transformer room and the low-voltage room, and the high-voltage and low-voltage rooms are fully functional.
●The high-voltage and low-voltage rooms are fully functional, and the primary power supply system on the high-voltage side can be laid out in a variety of power supply modes such as loop power supply, terminal power supply, dual power supply, etc. It can also be equipped with a high-voltage meter.
●The primary power supply system on the high-voltage side can be arranged in various power supply methods such as ring network supply, terminal power supply and dual power supply, etc. High-voltage measuring components can also be installed to meet the demand for high-voltage measurement. The transformer room can choose S9, SC and other series of low-loss oil-immersed transformers or dry-type transformers.
●The low voltage room can adopt panel or cabinet structure to form the power supply scheme required by users according to their requirements, including power distribution, lighting distribution, reactive power compensation, power supply system, power supply system, and power supply system.
●There are power distribution, lighting distribution, reactive power compensation, power metering and power measurement functions to meet the different requirements of users. It also facilitates power supply management and improves power supply quality.
●The HV room is compact and reasonable in structure.
●The HV room is compact and rational in structure, and is equipped with comprehensive anti-misoperation interconnection functions. The transformer can be equipped with rails for easy access from both sides of the door of the transformer room if required by the users.
●The transformers are equipped with rails for easy access from both sides of the transformer room doors when required by the user. All rooms are equipped with automatic lighting devices, and all components selected for high and low voltage rooms are reliable, easy to operate, and make the products safe, reliable, and easy to maintain.
Safe and reliable operation and easy maintenance.
●Natural ventilation and forced ventilation are adopted. The transformer room and the high and low voltage rooms are equipped with ventilation ducts, and the exhaust fans are equipped with temperature control devices that can automatically start and close according to the set temperature to ensure that the transformer can be operated safely and reliably.
