Zbw-12 Zbn-12 Series Combined Substation

Sumrmay:

ZBW(N) series combined substation is a compact set of distribution equipment which is composed of high-voltage electrical equipment, transformer, low-voltage electrical equipment and so on. It is used in urban high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mining oilfields and temporary construction power supply places as distribution system. Receive and distribute power.

This product has the characteristics of complete set, small size, compact structure, safe and reliable operation, convenient maintenance and movability. It occupies only 1/10-1/5 of the same capacity of conventional civil substation, which greatly reduces the construction cost. In the distribution system, it can be used in ring network distribution system, dual power supply or radiation terminal distribution system. It is the preferred new type of equipment for the construction and transformation of urban and rural substations. This product symbol GB/T17467-1998 "High Voltage/Low Voltage Pre-installed Substation" standard and IECl330 standard.

No dangerous places of violent vibration, shock and explosion.

3. Structural characteristics:

The product is connected by high voltage distribution device, transformer and low voltage distribution device. It is divided into three functional compartments, namely, high voltage chamber, transformer chamber and low voltage chamber. The HXGN-10 ring cabinet is a primary power supply system. It can be arranged into ring network power supply, terminal power supply, dual power supply and other power supply modes. It can also be equipped with high-voltage metering elements to meet the requirements of high-voltage metering. Transformers can choose S7, S9 and other low-loss oil-immersed transformers or dry-type transformers. The transformer room is equipped with automatic forced air cooling system and lighting system. The low-voltage room can adopt panel or cabinet-mounted structure to form the power supply scheme required by the user according to the user's requirements. It has many functions such as power distribution, lighting distribution, reactive power compensation, electric energy measurement, etc. It meets the different requirements of the user and is convenient for the power supply management and management of the user. Improve the quality of power supply.

The structure of the high-pressure chamber is compact and reasonable, and it has comprehensive anti-misoperation interlocking function. All rooms have automatic and forced lighting devices. In addition, all the components used in the high and low pressure chambers are reliable in performance and easy to operate, which makes the products safe and reliable in operation and convenient in maintenance.

Natural ventilation and forced ventilation are adopted. Make ventilation cooling well. Transformer chamber and low-voltage chamber have ventilation duct, exhaust fan has temperature detection device, according to the setting temperature can automatically start and close, to ensure that the transformer meets the load operation.

The box structure can prevent rainwater and dirt from entering, and is made of hot-dip galvanized coloured steel sheet or rust-proof aluminium alloy sheet, which is treated with anticorrosion. With long-term outdoor use conditions, to ensure anti-corrosion, waterproof, dust-proof performance, long service life, and beautiful appearance.

4. Plane layout and shape ruler:

ZBW series combined substation, according to the arrangement, can be divided into "item" and "product" word arrangement, can also evolve into other types according to need.

European box substations are 30KVA ~ 2500KVA 10KV 35KV, terminal type (Z), loop type (H), combined high and low voltage system and power transformer. Metal box, stainless steel or environmentally friendly, landscape type non-metallic box are selected by users. The price of box-to-box products shall be determined according to user's technical drawings and requirements.
