Product Description

Distribution Transformer power transformer step up step down transformer
1.General Characteristics
The transformers electrical design results mainly from:
• Power rating,
• Primary and secondary voltage levels,
• Ambient temperature and temperature rise,
• Altitude of installation,
• Short-circuit impedance,
• Vector group,
• No load losses,
• Load losses,
• Frequency,
• Permissible tolerances,
• Other particular conditions.
2.Oil-immersed and three-phase distribution transformers2.1.Standard:IEC2.2.Rated power:50-2500 kVA2.3.Rated frequency: 50 Hz2.4.HV rating:up to 36 kV2.5.Taps on:2.5 %or 2x 2.5 %2.6.HV side:As request2.7.LV rating:400-720 V(special designs for up to12 kV can be built)2.8.Connection:HV winding: delta
LV winding: star(up to 100kVA: zigzag)2.9.Cooling:ONAN2.10.Protection class: IP002.11.Final coating:RAL 7033 (othercolours are available)

3.Application
Distribution transformers are the end equipment before electricity reaches theconsumer. They provide low voltage by transforming the network medium voltage.
In most cases, transformers are designed as liquid filled particularly as oil immersedtype.
These transformers have usually apower ranging from 50 to 2500kVA, with amaximum operating voltage of 36kV.
4.Mechanical Features
4.1.Core
The magnetic circuit is of the three columntype with mitred joints. It is manufacturedwith first-rate,grain oriented silicon ironsheets insulated with carlite. The mountedcore is clamped down in order toreducevibrations and minimise noise levels.
4.2.Windings
The windings are made of either copper oraluminium; they are insulated with either purecellulose or double enamel. Furthermore, thecomplete columns are manufactured to withstand short circuit stresses.
4.3.Off-circuit tap changer
The tappings (±2 x2.5%) of the HV winding,are connected to the off-circuit tap changerlocated horizontally between the yoke andthe tank cover. The handle is located on thecover and should be operated when the transformer is deactivated. The design preventssetting the off-circuit tap changer to intermediate positions. The mechanism can also bepadlocked during normal transformer operation.
4.4.Insulating oil
The mineral oil with its electrical and chemicalcharacteristics is in compliance with the IECStandards and is P.C.B. and P.C.T. free.
4.5.Tank and cover
The sides of the tank are made of corrugatedcooling surfaces. The bottom plate, side andframes are of awelded construction. The weldsare tested for oil tightness. The thermometerpockets, bushings, tap switch drive and liftinglugs are fitted on the tank cover. The cover isbolted to the tank frame. The undercarriage iswelded to the bottom plate and the rollers aresuitable for either longitudinal or transversemovements.
4.6.Painting and surface treatment
Transformers are either hot-dip galvanized orpainted. The metal parts are carefully sandblasted. The painting system is asingle coatone pack epoxy. The top coat is RAL 7033 orcustomized. The hot-dip galvanizing is 70 µmminimum.
4.7.Options and accessories
- Plug-in bushings on HV
- Max thermometer
- Dial type thermometer with two contacts
- Oil level indicator for hermetically sealedtransformers
- Off-circuit tap changer with 3or 7positions
- Sparking gaps
- Pressure relief device
- Cable boxes
- Integrated pole brackets on tank
- Skid base
- Bi-directional rollers
- Total enclosure on cover over HV and LVBushing
4.8.Testing
The transformers are manufactured in accordance with ISO 9001 and ISO 14001. At theend of the manufacturing process the transformers are individually tested in accordancewith the IEC Standards.
4.9.The routine tests are:
- Measurement of the winding resistance
- Measurement of the voltage ratio and checkof the vector group
- Measurement of the impedance voltage andmeasurement of load losses
- Measurement of no load losses and noload current
- Dielectric tests
