ZBW box change
Prefabricated substation
Scope of application ：
It is a new transformer substation after civil transformer substation.
product details
ZBW series box substation is a kind of high voltage switch equipment,distribution transformers and low voltage power distribution equipment,according to the wiring scheme must be arranged in one of the factory indoor,outdoor compact type distribution equipment,the step-down transformer,low voltage power distribution,and other functions organically combined together,installed in a moisture,rust,dust,rat,fire prevention,guard against theft,thermal insulation,fully enclosed,movable steel structure,especially suitable for city network construction and retrofit,is the civil substation after the rise of a new substation.
ZBW series combined substation has complete sets of strong,small size,compact structure,safe and reliable running,convenient maintenance,as well as the characteristics of mobile,compared with the conventional civil type transformer substation,with the capacity of the combined substation area usually only 1/10~1/5 for conventional substation,greatly reducing the workload of design and construction,reduce the construction cost,in a series of distribution,distribution system can be used in the ring network,and also can be used for double power supply or radiation terminal power distribution system,is currently the substations in urban and rural areas and the election of the new type of complete sets of equipment.
This product conforms to GB/t17467-2010"high voltage/low voltage pre-installed substation"standard requirements.

Iii.Model and meaning
Iv.Product structure features
Change the basic structure of the box is divided into"eye"and"product"glyph,glyph skeleton box body is made of high quality channel steel and Angle steel welded together,has high mechanical strength,the box body made of aluminum alloy profile has good anticorrosion ability,beautiful appearance after spray paint color can be in harmony with the surrounding environment,designed at the bottom of the lifting device,to install mobile provides great convenience of transportation.
There are independent high-voltage room,transformer room and low-voltage room inside the cabinet,and the lighting of each room will open automatically with the opening of the door.High voltage ring network switching equipment is installed in the high voltage room,and the compressed air/vacuum load switch can be selected according to the needs of users,and it has the function of"five prevention".
Transformer chamber adopts natural ventilation and automatic control of forced cooling air cooling device,varies with changes in temperature and exhaust system of automatic control,control can effectively reduce the temperature in the cabinet,to meet operation requirements,according to user requirements can also adopt the condensation prevention device,according to the requirements of users,is along the track can be conveniently from the pressure chamber between the both sides from the gate in and out.The material of box body can prevent rain water and dirt from entering,and has the condition of long-term outdoor use,which can ensure anti-corrosion,waterproof and dustproof performance,long service life,simple maintenance and beautiful appearance.
The transformer can be dry type or oil-immersed type,oil-immersed type transformer can choose two kinds of oil pillow and oil pillow completely sealed.
The low-voltage chamber has the general function of low-voltage switchgear assembly,which can be selected and combined by users.
Shell material:shell material has composite plate,stainless steel composite plate,aluminum clad zinc plate,stainless steel plate,metal carving board.
Structural features:high pressure structure is reasonable and compact,can choose SF6,FZN57,VHC ring network cabinet,all with the function of five-way interlock.
Transformer natural ventilation and automatic ventilation cooling system can be used for dry and oil-immersed transformers.
Low-voltage room:according to user requirements,various power distribution schemes can be adopted,including power distribution,lighting distribution,reactive power automatic compensation,electrical energy measurement and other functions,equipped with automatic lighting system.
