YBW intelligent integrated outdoor substation European box substation

Overview

European-style box-type substations (MV/LV Prefabricated 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.

Features

1. Advanced technology, safe and reliable

The box body part adopts domestic and foreign leading technology and craftsmanship. The outer shell is generally made of galvanized steel plate. The frame adopts standard container materials and manufacturing techniques. It has good anti-corrosion performance and guarantees no corrosion for 20 years. The inner sealing plate adopts aluminum alloy buckle plate, sandwich Using fireproof and thermal insulation materials, air conditioning and dehumidification devices are installed in the cabinet, the operation of the equipment is not affected by the natural climate environment and external pollution, and it can ensure normal operation in the harsh environment of -40℃~+40℃.

2. High degree of automation

The whole station is intelligently designed. The protection system adopts the integrated automatic device of the substation and is installed in a decentralized manner. It can realize the "four remotes", namely remote measurement, remote signaling, remote control, and remote adjustment. Each unit has independent operation function and relay protection. The function is complete, and the operating parameters can be remotely set, and the humidity and temperature in the box can be controlled to meet the requirements of unattended operation.

3. Factory prefabrication

When designing, as long as the designer makes a design of the main wiring diagram and the equipment outside the box according to the actual requirements of the substation, he can choose the specifications and models of the box substation provided by the manufacturer. The factory construction of the power station shortens the design and manufacturing cycle; on-site installation only requires cabinet positioning, cable connection between cabinets, outgoing cable connection, protection setting verification, transmission test and other work that needs to be debugged. The entire substation is from installation to It only takes about 5 to 8 days to put into operation, which greatly shortens the construction period.

4. 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.

5. 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%.

6. Small footprint
