ZBW Prefabricated Substation (European)
This series of prefabricated substations is suitable for 12kV, three-phase AC system with rated frequency of 50Hz. The capacity is set in residential quarters of 2500kVA and below, commercial buildings, large-scale construction sites, high-rise buildings, industrial and mining enterprises and temporary construction sites. Ring network power supply is also suitable for radial terminal power supply. The prefabricated substation of this series has the advantages of compact structure, strong set, safe and reliable operation, convenient maintenance and beautiful appearance. It has small volume, small floor space, large selectivity, small on-site installation and short installation height cycle. And the characteristics of moving with the load center.
Model and its meaning
2. The high-voltage side generally adopts a load switch, and can also adopt a vacuum circuit breaker, and has a complete anti-misoperation function. Such as optional: XGN20-12L SF6 ring network cabinet, HXGN15A, HXGN17 and other ring network switch equipment. The transformer can be oil-immersed transformer, fully sealed transformer, dry-type transformer, and low-voltage room equipment can be selected with GGD1 (2, 3).
5. The cabinet is naturally ventilated, and forced ventilation equipment can also be installed. A dustproof device is mounted on the outer side of the door panel and the side panel corresponding to the louver.
The box body of the prefabricated substation of this series is mainly composed of a base, a side plate, a partition plate, a door and a top cover, and the box body is divided into a high pressure chamber, a transformer , and a low pressure chamber. The protection level of the cabinet is IP23. The sealing plates, partitions, doors and top covers above the base are made of cold-rolled steel sheets. Connected together by welding or fasteners. Have enough mechanical strength. The inner and outer surfaces of each part of the box are sprayed to form a durable protective layer. The cabinet is protected from rain, sun, rust and ventilation as the most advanced structure at home and abroad.
2. The foundation is located at a higher elevation, draining from the outside, using 200# cement mortar, 3% waterproofing agent, slightly inclined to the oil tank at the bottom (cancel the oil tank when dry)
5. The dimensions in the figure are recommended values.
2. The high pressure chamber is compact and reasonable, and has a comprehensive anti-misoperation interlock function. When the transformer is required by the user, the transformer can be provided with a track, which can be easily accessed from the gates on both sides of the transformer room. Each room has automatic lighting devices. In addition, all components selected for the high and low pressure rooms are reliable in performance and easy to operate, making the products safe and reliable, and easy to maintain.
