◆Product Summary

YBM series prefabricated substation is a compact distribution device including HV switchgear,distribution transformer,LVswitchgear,electric energy metrological device and reactive power compensator,all devices are packaged in one or several cubicalunits,which are wired by correct logic electrically schemes.It is suitable for three phase AC system with rated voltage of 10/0.4kV.Itcan be used to receive and distribute electric energy to factories,mines,oil fields,ports,airports,urban public buildings,highways,underground facilities and other places.

The prefabricated substation is featured technically by strong whole apparatus character,compact volume,good appearance,safeand reliable operating,easy maintenance,good appearance,convenient movement,deeply involved in load center,short constructionperiod,and waste reduction and other advantages.

◆Environmental Conditions

1.Altitude:No more than 1000m.

2.Ambient Temperature:No more than +40℃ and no less than -45℃.

3.Relative Humidity:the average daily value is no more than 95%,the average monthly value is no more than 90%.

4.Earthquake proof Level:Horizontal Accelerations≤0.3g,Vertical Acceleration≤0.15g.

5.Installation Location:Well-ventilation,chemical corrosion and violent vibration for product installed place.Vertical slope of lessthan 3 degrees.

◆Product Features

1.The cabinet has two structures:one is skeleton welding,which weld skeleton with steel first,then pull riveting or weld panel.Anotheris skeleton assembly,the steel plate is formed by bending and forming the surface.Finally,the steel plate is assembled by boltconnection.The skeleton assembly is characterized by the expansion of the low voltage outgoing unit,which can be placed with noless than 6 panels of low voltage switchgear,with 8-12 loops.The prefabricated substation can be set up to operate the hallway andduty room.

2.It has good heat insulation and ventilation measures.A double layers structure is adopted in the cabinet,and the heat insulationmaterial is also set in the interlayer,which effectively reduces the temperature rise caused by sunshine.The transformer compartment isarranged on the top of the side gate automatic ventilation fan,the upper part is provided with a shutter,can guarantee that thetransformer can worksafe at full load in high temperature season.

3.Safe and reliable operation.The H.T side of the transformer substation selects RMU model XGN15-12 and SRM-12,could alsoadopt other types of metal clad switchgear,complete five-preventions interlock.Each door frame has good waterproof structure.

4.It is convenient to operate and maintain.Each compartment has automatic lighting device,transformer compartment has track andcart,convenient for transformer installation,maintenance and replacement.The H.T and L.T compartments adopt front wiring and frontmaintenance.

5.The appearance is beautiful and durable.The cabinet shell is made of high performance marine zinc rich epoxy primer and epoxyanticorrosive mortar,which has good anticorrosive property,and the surface color can be configured arbitrarily with the environment.All electrical installations are all galvanized,and it adopts a special anti blocking and anti rust universal lock.
