Product Advantages


Core:


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° mitring and steps overlapping structure is used for core production, enable the effectiveness of reducing no-load loss and no-load current.

HV winding:


HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.

LVwinding:


LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.

 

Introduction 

 

By winding number

 

35 kV class 3-phase two-winding power transformer

 

By tap-changing

 

35 kV class on-load tap-changing power transformer

 

 

35 kV class off-load tap-changing power transformer

 

 

Insulation Structure:


The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.

Tank:


The tank conservator tank type with radiator fins. 


Executed Standards:
IEC60076

 

Leakage reparation

Leakage on welding line
Contact with transformer manufacturer.

 

Leakage on meter device
Contact with transformer or apparatus manufacturer.

 

 Leakage on conservation

 Reason for the acting of protector while the transformer running

Possible warning or action:

 Body conservator and on-load tap-changer oil-level contact.

 

Contact action case Reason Solution
Alarm for over low oil-level Oil leakage Find out and repair the point of leakage
Over low temperature outside Infuse a appropriate amount of transformer oil.
Alarm for over high oil-level Heavy load, exceed limit load

to compare with the oil thermometer indicator.

Check the load going. If it’s too high, decrease it.

Over amount of transformer oil Adjusting oil-level in the conservator

 

 Oil thermometer contact

 

Contact action case Reason Solution
Alarm for oil temperature At limit load

Check whether the connected valves between the transformer and cooling device are expedite.

Check whether the load going has been over burden.

Decrease it before continue.

Trip Abnormal cooling device operation
heavy load, exceed limit load

 

 Windings temperature contact (if equipped)

 

Contact action case Reason Solution
Alarm for winding temperature At limit load

Check whether the connected valves between the transformer and cooling device are expedite.

Check whether the load going has been over burden.

Decrease it before continue

Trip Abnormal running state of cooling device
