Delta this product is composed of high voltage power distribution equipment, transformer and low voltage power distribution equipment connection and become, is divided into three functional compartment, namely, high voltage room, transformer room and low pressure chamber, high and low pressure outside the function is all ready, high side power supply system, can decorate cyclization with double power supply power supply, terminal power supply, power supply a variety of ways, can also be installed high pressure measuring element, meet the needs of high pressure measurement.Transformer room can choose S9, SC and other series of low-loss oil-immersed transformer or dry transformer;According to the requirements of users, low-voltage chamber can adopt panel or cabinet structure to form the power supply scheme required by users, with various functions such as power distribution, lighting distribution, reactive power compensation, electric energy measurement and electricity measurement, etc., to meet the different requirements of users.And to facilitate the user's power supply management and improve the quality of power supply.
The high pressure chamber is compact and reasonable, and has the function of preventing misoperation interlock.When the transformer is required by the user, the track can be conveniently used to enter and exit from the two sides of the transformer room.Each room is equipped with automatic lighting device. In addition, all the components selected for high and low pressure rooms are reliable in performance, convenient in operation, safe and reliable in operation and convenient in maintenance.
Two modes of natural ventilation and forced ventilation were adopted.Transformer room and high and low voltage room are equipped with ventilation duct, and the exhaust fan is equipped with temperature control device which can automatically start and close according to the set temperature to ensure the normal operation of the transformer.
The box variable structure can prevent rain water and sewage into the material selection of color steel plate production, anti-corrosion and heat insulation function.With long-term outdoor use conditions, ensure anti-corrosion, waterproof, dustproof performance, long service life, and beautiful appearance.
