Pre-fabricated substation High And Low YB6-12/0.4

Item : YB6

The YB6-12/0.4pre-fabricated substation is used as assembly device of power transformation,power distribution,compensation,and protection equipment in the ring network of12kv,double power supply and terminal power supply system rated 12kv. Berides transformer,there is 4-position or 2-position load switch ,protection fuse and plug type  fuse on HV side ,there is control and distribution device,compensation device and meters on the LV side,the insulation and arc extinction medium are transformer oil .The transformer and the HV switch equipment are installed inside different oil-cases. The two kinds of equipments is only connected electrically,but separated by different oil-cases. The arc of load switch just make the oil inside the oil-case become blacker  or carbonized ,won’t effect the quality of the oil.
The transformer adopts the model S10.This product is equipped with lose-phase protection device .When the lose-phase occurs,it can simultaneously auto-break the incoming load switch of transformer and LV side circuit breaker (general switch),Breaking any of the HV side load switch or LV side load  circuit breaker is also permissible ..It has features as small volume,convenient installation and maintenance ,low noise, low consumption,theft guard ,high overload capability and full protection ,etc.it is applicable for those sites as residential areas,city green belt ,park,station,dock,hotel and airport,etc.
