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

 

Acomprehensive inspect per year:

 

To shut off and ground the main terminals before inspecting.

 

Inspection and testing project Possible problem or item need to be examined Solution
The overall of the transformer Leakage Comply with article 13- repairing leakage
Rusty Clean and repair corrosion point
Bushing Terminal Rusty -Clean surface carefully
-Painted with grease on the contact surface.
Screw connection Loose Re-tighten
Porcelain cover Crack, damaged Instead the porcelain cover or bushing
  Oil level thermometer Oil level too high or too low Comply with the application and installation instruction of bushing and adjust oil-level.
Ground terminal Signs of a rusty Comply with the application and installation instruction of bushing
Fixed connections have become loose Re-tighten them.
Oil level Conservator of body and oil level Oil level is too high or too low Comply with the instruction of oiling and oil-expulsion, then control oil level.
Conservator of on-load tap-changer and oil level Oil level is too high or too low Comply with the instruction of oiling and oil-expulsion, then control oil level
Oil state Capability to be worse than oil instruction manual Comply to the use of sieve equipment for the renewable oil of oil-processing.
On-load tap-changer Appearance checking leakage Compliance with “on-load switch instruction manual” and “instruction of the electric structure”
Work state Heater failure
Number of operations Shows when reached or exceed the maximum number of operations Conform to “switch instruction manual”
