Application:European box substation, also known as outdoor substation, also known as combined substation, because of its flexible combination, easy to transport, relocation, easy to install, short construction period, low operating costs, small footprint, pollution-free, maintenance-free and other advantages, has been widely valued. In the construction (transformation) of agricultural network, it is widely used in the construction and transformation of urban and rural 10~110kV small and medium-sized substations (distribution), factories, mines and mobile substations, because it is easy to penetrate into the center of the load, reduce the radius of the power supply, and improve the quality of voltage at the end, which is especially suitable for the transformation of the rural power grid.
Product Features
1,Advanced technology, safe and reliable
Box part of the domestic leading technology and process, the shell is generally used aluminum-plated zinc steel plate, the framework of the standard container materials and production process, has good anti-corrosion performance, to ensure that 20 years without rust and corrosion, the inner sealing plate using aluminum alloy buckled plate, the mezzanine layer of fireproof thermal insulation materials, the box is installed inside the air conditioning and dehumidification device, equipment operation is not affected by the natural climatic environment and external pollution, to ensure normal operation under the harsh environment in the -40 ºC ~ +40 ºC. The equipment operation is not affected by natural climate environment and external pollution, and can guarantee normal operation under the harsh environment of -40ºC~+40ºC.
The primary equipment in the box adopts unit vacuum switchgear, dry-type transformer, dry-type transformer, vacuum circuit breaker (spring-operated mechanism) and other leading domestic technology equipment, no exposed live parts of the product, for the fully insulated structure, can achieve zero electrocution accidents, the whole station can realize the oil-free operation, high security, the secondary microcomputer integrated automation system, can realize unattended.
2,High degree of automation
Intelligent design of the whole station, the protection system adopts the microcomputer integrated automation device of the substation, decentralized installation, which can realize "four remotes", i.e., telemetry, telecommunication, remote control, remote adjustment, each unit has independent operation function, complete relay protection function, remote setting of operation parameters, humidity and temperature control inside the box, which can satisfy the requirement of unmanned operation.
3,Factory prefabrication
When designing, as long as the designers make a main wiring diagram and the design of equipment outside the box according to the actual requirements of the substation, they can choose the specifications and models of the box-type transformer provided by the manufacturer, and all the equipments are installed and commissioned in the factory at one time, which really realizes the construction of the substation to be factoryized, and shortens the design and manufacturing cycle; the on-site installation only requires the positioning of box body, the cable liaison between boxes, the connection of outgoing cables, and the calibration of the protection value, Transmission test and other debugging work, the entire substation from installation to commissioning in about 5 to 8 days, greatly reducing the construction period.
4,Flexible combination
European box sustation due to the more compact structure, each box constitutes an independent system, which makes the combination of flexible and variable, we can all use the box, that is, 35kV and 10kV equipment are all installed in the box, the composition of the whole European box substation; can also be used for the outdoor installation of 35kV equipment, 10kV equipment and control and protection systems installed in the box, the combination of this way, especially for the transformation of agricultural networks in the old This combination is especially suitable for the transformation of the old agricultural network, i.e. the original 35kV equipment does not move, only install a 10kV switch box to achieve the requirements of unattended.
5,Saving investment, quick results
European box sustation (35kV equipment outdoor layout, 10kV equipment box installation) than the same size synthesized from the substation (35kV equipment outdoor layout, 10kV equipment arranged in the indoor high-voltage switchgear room and the control room) to reduce the investment by 40% to 50%.
6,Small footprint
