ZBW Prefabricated Substation (European)

ZBW Prefabricated Substation (European)

■Overview

ZBW series prefabricated substation (European) is a series of products designed and developed by our company to meet the needs of urban network construction. This series of products is a complete set of power distribution equipment that combines medium voltage switchgear, transformer and low-voltage power distribution equipment into one unit.

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.

Use environment

Ambient air temperature does not exceed +40 ° C, minimum ambient air temperature - -25 C; altitude does not exceed 1000 m, if special transformers and low-voltage components are used, the vertical inclination of up to 3000 m can not exceed 5 °, no Places with severe vibration and no impact; air humidity not greater than 90% (+25C); no conductive dust, no explosion hazard, no corrosive metal and electrical components of gas places; outdoor wind speed does not exceed 35m / s.

Model and its meaning

■Product design features

1. The shell is designed according to the actual situation with reference to foreign advanced technology. It has the characteristics of firmness, heat insulation, good performance, moisture resistance, small animals, moisture proof, beautiful appearance and convenient maintenance. There are many options for housing materials. Such as: aluminum alloy precipitation, steel plates, composite plates, stainless steel plates, non-metallic materials (glass fiber cement).

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).

3. Substation protection performance is perfect, easy to operate, high and low pressure metering is available for selection, and automatic no power compensation device can be equipped according to user requirements.

4. The top cover of the box is designed as a double-layer structure, and the interlayer is filled with foam plastic and has good heat insulation effect. The high and low pressure chambers are designed with an independent top plate inside, and the transformer room is equipped with anti-condensation and automatic temperature control monitoring, heating and cooling devices.

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.
