YB□-40.5(12)series prefabricated substation(hereinafter referred to as substation)is a prefabricated complete set of power distribution device,which is composed of high-voltage power distribution device,transformer and low-voltage power distribution device according to a certain wiring scheme.It is used for 40.5(12)0.4KV or 40.5/12KV AC three-phase system,to be a integrated power transformation and distribution device for acceptance&distribution of electric energy.
YB□-40.5(12)substation is an outdoor type product,which doesn’t occupy the building area,saves the construction cost,small size,light weight,beautiful appearance,compact structure,and easy to install.It can fully meet the requirements of IEC1330 standard,and is suitable for urban public power distribution,street power supply,industrial and mining enterprises,high-rise buildings,residential areas,oil fields,docks and construction sites etc.
● The device consists of high-voltage power distribution device,transformer and low-voltage power distribution device.It is divided into three function rooms that are high-voltage room,transformer room and low-voltage room.The high-voltage room has complete functions and can be arranged into ring power supply,terminal power supply,dual power supply and others.It can also be equipped with high-voltage metering elements to meet the requirements of high-voltage measurement.
● The low loss oil immersed transformer or dry-type transformer is optional.Transformer room is equipped with automatic forced air cooling system and lighting system.
● According to the user's requirements,the low-voltage room can use panel or cabinet mounted structure to form the power supply scheme required by the user,which has the clock functions of power distribution,lighting distribution,reactive power compensation,electric energy measurement etc,which can meet the user’s different needs,and convenient for the user's power supply management and improve the quality of power supply.
● The high voltage room is with compact and reasonable structure,and has comprehensive anti misoperation interlocking function.Each room has automatic and forced lighting devices.In addition,all components for high and low voltage rooms are with reliable performance and easy to operate,which makes the product operation is safe and reliable,and is convenient for the operation and maintenance.
● Natural ventilation and forced ventilation to make the ventilation and cooling very well.There are ventilation channels in transformer room and low-voltage room,and the ventilation fan has temperature detection device,which can automatically start and close based on the set temperature to ensure that the transformer can meet the load operation.
● The cabinet structure can prevent rainwater and sewage and is made of hot-dip galvanized color steel plate or antirust aluminum alloy plate.After anti-corrosion treatment,it can be used for outdoor in long-term,ensuring the anti-corrosion,water-proof and dust-proof performance,long service life and beautiful appearance.
