KS11-50~1000/10

Three phase mining oil immersed power transformer

●Ks11 series of mine transformer used in coal mine underground central substation, bottom, total intakes and main intakes, although have gas but no explosion hazard. Can also be appled to tunnel is the damp environment.
●Normal use Environment: Elevation less than 1000m Temperature Range:-25 ℃~+45℃.
●Especial Environment: Elevation more than 1000m: Temperature Range :-45℃~+40℃.
●IThe surrounding air relative humidity is not more than 95% (+ 250 ℃).
●No severe turbulence vibration and vertical gradient of no more than 35 ℃ environment.

Technical Paraweters

Executive Standard: ●JB/T3955-2006 Power transformer
●GB 1094.1-2003 Power transformer
●GB/T1094.3-2003 Power transformer
●GB 1094.5-2008 Power transformer
●GB1094.2-2013 Power transformer
●The international standard IEC76

Performance Characteristic: ●Tank structure, strong, can bear the pressure test of an atmospheric pressure, there is no storage tank lid tank walls on both sides of the welding of high and low voltage cable junction box, for the use of cable wiring. High voltage coil with rated voltage and the voltage of plus or minus 5% points, using tap-changer transform voltage, voitage transformation must cut off power supply first, and then remove the box wall tap-changer change points atfter the storm of the hood.
●the low voltage side of transformer to allow "Y"shaped into 690 v power supply, also can convert into a' delta"form into 400 v power supply, the cable terminal box directly to the subprime end raises six porcelain jacket for modified by the user.
●The lift, the transformer is to use the box wall hanging welding by mixing, transformer with the car at the bottom of bracket, equipped with mounting holes on the bracket, for the mine will be required to have car wheel.
