Rectifier transformer is used for rectifier-fitting power supply,most industrial DC power supply is gained by alternative current network equipment which is made up of rectifier transformer and rectifier.Its widely used on electrolyse of electrochemistry,traction,transmission DC transmit electricity,frequency conversion and common industrial rectifier power supply and other areas.

 

Model/type of rectifier transformer is composed by bellowing codes:

Use---line side phase---insulation dielectric outside winding---sorts of cooling equipment---oil-circulating type---voltage regulating type---inner contains attached equipment---rated capacity---voltage class

 

Use:electrolyse of electrochemistry ZH,traction ZQ,transmission ZS, DC transmit electricity ZZ,frequency conversion ZP,common industry ZB

Line side phase: single-phase D, three-phase S

Insulation dielectric outside winding:transformer oil(dry type)G

Sorts of cooling equipment:natural cooling-air cooling(F),water cooling(S)

Oil circulation type:natural circulation-force oil circulation P

Voltage regulating type: off-circuit regulating or no regulating---by line side winding  on-load regulating Z by inner attached auto-regulating transformer or series regulating transformer on-load voltage-regulating T by saturable reactor voltage-regulating B

Inner contains attached equipment: without inner attached equipment-interphase reactor K, saturable reactor HK

 

For example:a set rectifier transforme, three phase,oil-immersed,air cooling,forced-oil circulation,inner contains attached auto-regulating transformer, on-load regulating.Rated capacity is20000KVA,voltage class is 35KV.Its type is :ZHSFPT-20000/35
