ODM Discount 33kv Gis Substation Factories – 20kV 5000kVA compact transformer substation – JSM TRANSFORMER Detail:

20kV 5000kVA compact transformer substation is also called outdoor complete substation, box-type substation, box-type transformer, also known as combined substation, because of its flexible combination, easy transportation, migration, convenient installation, short construction period, low operating cost, and small footprint , Pollution-free, maintenance-free and other advantages, have been widely valued. Because it is easy to go deep into the load center, the power supply can reduce the radius of power supply, improve the quality of power supply, reduce power loss, and enhance the reliability of power supply. It is especially suitable for power grid transformation.Rockwell box substation manufacturer, the box substation produced meets the standards of GB17467-1998 “High and Low Voltage Prefabricated Substation” and IEC1330.

Features:

1. Safe & Reliable
Shell generally adopts aluminium zinc steel plate, frame with a standard container material and production process which has good anti-corrosion performance for 20 years guaranteed. The inner sealing plate is made of aluminum alloy buckle plate, and the sandwich is made of fireproof and thermal insulation material. The air conditioning and dehumidification device are installed in the box. The operation of the equipment is not affected by the natural climate environment and external pollution, and the normal operation can be guaranteed under the harsh environment of -40℃ ~ +40℃. The primary equipment in the box is fully enclosed, the product has no exposed live part, which can completely achieve zero electric shock accident, the whole station can realize oil-free operation, high security, the secondary use of microcomputer integrated automation system, which can realize unattended.

2. High degree of automation
Total station intelligent design, protection system adopts microcomputer integrated substation automation equipment, installation, which can realize telemetry, remote communication, remote control, remote regulating. Each unit has independent operation function. The relay protection function is complete, which can set the operating parameters in the distance, control the humidity and temperature in the box body and alarm the smoke in the distance, so as to meet the requirements of no one on duty.It can also realize remote image monitoring according to the need.

3. Factory prefabrication
When designing, as long as the designer according to the actual requirements of the substation, provide a main wiring diagram and the design of equipment outside the box, manufacturers can carry out a installation and debugging of all equipment, truly realize the substation construction factory, shorten the design and manufacturing cycle. On-site installation only needs box positioning, cable connection between boxes, outgoing cable connection, protection calibration, transmission test and other commissioning work. The entire substation from installation to commissioning only needs about 5 ~ 8 days, greatly shortening the construction period.

4. Flexible combination mode
Box type substation structure is compact, each box constitutes an independent system, which makes the combination of flexible, on the one hand, we can all use the box, so that 35kV and 10kV equipment all installed in the box, the composition of the whole box type substation; 35kV equipment can also be installed outdoors, and 10kV equipment and control and protection system can be installed inside the box. This combination mode is especially suitable for the transformation of old rural power grid stations. In short, there is no fixed combination mode of compact substation, and the user can combine some modes freely according to the actual situation to meet the needs of safe operation.

Structural features
1. The performance of our S9 S10 S11S13 series 20kV and 35kV three-phase oil-immersed transformer conform to the standard of GB 1094-1996 “Power Transformer “ and GB/T6451-2008 “Technical Parameter and requirements of Three-phase Oil-immersed Power Transformer”.
2 The iron core is made of quality cold –rolled silicon steel sheet , and the coil is made of quality oxygen-free copper, featuring good outlook and safe running.
3 The products are widely used in power transmission and distribution of industrial and agricultural power networks.
4 Iron core is made of cold-rolled silicon-steel sheet with high conduction of magnetism and adopts pulling-plank structure, so that its magnetic route is short, losses and noise level is low;
5 Compress wire is adopted for winding so losses are low and have good ability withstand short-circuit;
6 Its active part adopts special pressing method which could ensure reliable axial pressure;
7 The oil tank is bell type with the structure of full folding plate type, having an excellent exterior and easy for maintenance;
8 Reliability: All in-service product have no damages or oil leakage occurred;
9 Oil tank with various kinds of structure and good appearance.
