JBW (ZBW20)-12 series compact Prefabricated Substation is a kind of integrated complete power transmission and distribution equipment, used in 6~10KV, AC 50Hz system with a Transformer rated capacity of 50~1250KV. It is widely used in outdoor power supply fields, such as city high-rise building,residential zone,factory and mining,hotel,hospital,part,oil field,airport,wharf,market,and other temporary facilities, etc.
JBW(ZBW20)-12 series compact prefabricated Substation can be used in a close-ring-net for power distribution, but also in transformation power net for terminal power supply.

Structure characteristic

This product has the advantages of smaller volume,compact structure,high heat insulation and ventilation function,dust-proof,prevent small animal to enter,moist-proof,beautiful appearance and convenient to maintenance, we can choose cold-rolled steel plate,compound color plate and other material to make up enclosure.
All the black material of substation are taken surface anticorrosive treatment, it will guarantee that product will be not corroded for a long time.
HV side use HXGN26-12(F), with complete operation mistake prevention function.

HV & LV primary scheme

Substation HV primary scheme, see table 4
Substation LV primary typical scheme, see table 5

Structure and appearance

Substation base plate and supporting structure adopt U-steel and angle steel, it has higher mechanical intensity, product enclosure adopts cold-rolled steel plate or compound color plate, we can't see threaded connection or rivet connection from the exposed surface, so it has beautiful appearance.
Use clapboard to divide into independent room between each room of substation. Layout diagram see diagram 1.
In order to observe and maintain, LV room and HV room have lighting device.
Reversible connecting parts of substation adopt rubber belt to seal, with good damp-proof capacity.
HV room is equipped with HXGN26-12(F) RMU, and also with SF6 load switch,fuse(adopts Circuit Breaker if it required),lighting arrester,earth switch and mechanical interlock device, if adopts HV measuring, it is also equipped with voltage transformer,Current Transformer and measuring meter. ,,,,,,,,,,,,,,,,,
Each LV elements in LV room should be frontal arranged, instrument room on the top, it has observing window on the front, each element has independent and removable plate, convenient to maintain.
According to the requirement of reactive compensation, it should be equipped electric device, its capacity is 15~20% of transformer
