YB□-12/0.4 Preparatory Transformer Substation



YB□-12/0.4 Preparatory Transformer Substation

Summarize:

It is mainly used for voltage of 3 kv, 6 kv, 12 kv power supply terminals and ring network system. Both can be used in outdoors and indoors. It is suitable for traffic places, such as: public places, residential areas, industrial and mining enterprises, airports, stations, ports, highways, subway and other places.

Characteristics:
　　

1.     Full sealed, full insulation structure, reliable guarantee personal safety, small volume, compact structure. The volume is only 1/3-1/5 of the same capacity of Europe type. And in that reason can save construction investment.

2.     Used for ring network and terminal power supply. Electric cable joint in a load shedding of 200A can pull plug for many times and can be used as an operating load switch. It has the characteristics of the isolator switch at the same time.

3.     It adopts double fuse full range of protection method, has low operation cost and low loss which is lower than the domestic integrated transformer S9.

4.     Chamber adopts anticorrosion design and special paint processing, is suitable for all kinds of bad environment. Like storms and high pollution area.

5.     It uses D, yn11 connection method, has neutral point, doesn't drift, low noise, good lightning protection performance, etc.

6.     It adopts Intelligent under voltage controller on the low voltage side which can cut off the power supply when there is abnormal voltage of the low voltage bus bar.

7.     It has complete functions and can match more than 20 low voltage circuit. It has measurement and compensation function also.

8.     The maintenance is simple. Free replacement of the transformer oil for 20 years.
