Function

It has the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, box-type substations with the same capacity usually occupy only 1/10 of the area of conventional substations. ~1/5, which greatly reduces the design workload and construction volume, and reduces the construction cost. In the power distribution system, it can be used in the ring network power distribution system, and can also be used in the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substations.

Features

1. Flexible combination

Due to the compact structure of the European-style box substation, each box constitutes an independent system, which makes the combination method flexible and changeable. We can all adopt box-type, that is, 35kV and 10kV equipment are installed in all boxes to form a full European-style box substation. ; It is also possible to use 35kV equipment for outdoor installation, 10kV equipment and control and protection system box installation, this combination method is particularly suitable for the transformation of the old rural power grid transformation, that is, the original 35kV equipment does not move, only install a 10kV switch box Can meet the unattended requirements.

2. Low investment and quick results

European-style box substation (35kV equipment outdoor layout, 10kV equipment box installation) compared with the same scale integrated substation (35kV equipment outdoor layout, 10kV equipment layout in the indoor high-voltage switch room and central control room) reduce investment by 40%~50%.

3. Small footprint
