What are the steps of using substation?

The internal structure of the substation is mainly composed of electrical units such as multi circuit high-voltage switch system, armored bus, substation integrated automation system, communication, telecontrol, metering, capacitance compensation and DC power supply. It is installed in a moisture-proof, rust proof, dust-proof, rat proof, fire-proof, anti-theft, heat insulation, fully enclosed and movable steel structure box with electromechanical integration, Fully enclosed operation.

What are the characteristics of Compact substation?

high degree of automation

The whole station is intelligently designed, and the protection system adopts the substation microcomputer integrated automation device, 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 complete relay protection function. , It can remotely set the operating parameters, control the humidity and temperature in the cabinet and remote smoke alarm to meet the requirements of unmanned duty; remote monitoring of images can also be realized according to the needs.

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, and all the equipment is installed and debugged in the factory to be qualified, and the substation is truly realized. The construction of factory, shortened 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 commissioning. It only takes about 5 to 8 days, which greatly shortens the construction period.



Why we say that Compact substation combined flexibly?

The compact design of the compact substation makes each box an independent system, making the combination process flexible and variable. On the one hand, we can use all the gearboxes of the box type, i.e. 35 kV and 10 kV devices are installed in all boxes to form a complete gear station; For this combination method, you can also use only 10 kV switch boxes, 35 kV equipment outlet installation, 10 kV equipment and control and protection system box installation, especially suitable for the transformation of the old station into the rural network transformation, i.e. the original 35 kV. The compact substation does not move, simply install a 10kv control box to meet the unattended requirements. In short, sub-stations of the cassette type do not have a fixed combination mode and the user can freely combine some modes according to the actual situation to meet the requirements of safe operation.



Why is the footprint of Compact substation small?

Taking 4000kva single main transformer scale substation as an example, to build a conventional 35kv substation, it takes about 3000m of area and large-scale civil works; and box-type substation is selected, the main transformer box and the switch box are two boxes. The minimum floor area can be as small as 100m, including 35kv other equipment, the total floor area 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 street center, square and corner of the factory. , In line with the country's land conservation policy.
