Product Features:
1.Advanced technology, safe and reliable
The box body adopts domestic 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, and the interlayer adopts fireproof and thermal insulation materials, air-conditioning and dehumidification devices are installed in the cabinet, and the operation of the equipment is not affected by the natural climate environment and external pollution, and can ensure normal operation in the harsh environment of -40℃~+40℃.
The primary equipment in the box adopts domestic technology-leading equipment such as unit vacuum switchgear, dry-type transformer, vacuum circuit breaker (spring operating mechanism), etc. The product has no exposed live parts and is a fully insulated structure, which can completely achieve zero electric shock accidents. The whole station can realize oil-free operation with high safety.
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 "four remotes", namely, remote measurement, remote signaling, remote control, and remote adjustment. Each unit has independent operation function and relay protection. Complete functions, remote setting of operating parameters, control of humidity and temperature in the box, to meet the requirements of unattended.
3.Factory prefabrication
All equipment is installed and qualified in the factory at one time, which 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 requires debugging. The entire substation takes about 5-8 days from installation to commissioning. Greatly shorten the construction period.
4.Flexible combination
Due to the compact structure of the European-style box change, each box constitutes an independent system, which makes the combination flexible and changeable.
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 indoor high-voltage switch room and central control room), reduces investment by 40%-50%.
6.Cover small space.
Taking 4000kva single main transformer scale substation as an example, the construction of a conventional 35kv substation requires an area of about 3000m, and large-scale civil works are required;If a box-type substation is selected, the minimum area of the main transformer box and the switch box can be as small as 100m, and the total area including 35kv and other equipment is up to 300m, which is only 1/10 of the area of the substation of the same scale. It can be installed and put into production by making full use of the center of the street, the square and the corner of the factory, which is in line with the national land saving policy.
7.Beautiful appearance
The box shell adopts aluminum-zinc steel plate and container manufacturing technology. The appearance design is beautiful. Under the premise of ensuring the reliability of power supply, by choosing the shell color of the box-type substation, it is easy to coordinate with the surrounding environment. It is especially suitable for urban construction.
