Features
1. Flexible combination mode. Because the structure of the European box substation is relatively compact, each box constitutes an independent system, which makes the combination mode flexible and changeable. European-style box substation; 35kV equipment can also be installed outdoors, 10kV equipment and control and protection system box installation, this combination method is especially suitable for the transformation of old substations in rural network transformation, that is, the original 35kV equipment does not move, only Install a 10kV switch box to meet the unattended requirements.
2. Low investment and quick results. European box substation (outdoor layout of 35kV equipment, installation in 10kV equipment box) is 40% less investment than integrated substation of the same scale (outdoor layout of 35kV equipment, 10kV equipment in indoor high voltage switch room and central control room) %~50%.
3. Small footprint
Overview
European-style box-type substations arrange high-voltage, distribution transformers, low-voltage power distribution devices, and electric energy metering equipment into a compact power distribution device according to a certain circuit plan, with a small footprint.
