Voltage Regulator Oil Immersed Power Transformer ONAF 110KV SZ
110kV Oil-immersed type power transformer
General :
Adopting advanced and strictly technology, the 110kV's transformer
that we develops to produce index all
achieves the advanced standard of international by way of
constantly exploring and make perfect. The product
possesses characteristics such as the low loss, low noise and low
power in part and the resisted short circuit
ability is strong etc. The product breed is diversified and the
model specifications complete.
The transformer product can be installed and use in outdoor or
indoor, and it is very ideal equipment in the
distribution network in factory, rural area and city.
Features:
1 Short-circuit capability
The use of advanced computer program for calculating the
transformer short-circuit conditions, analysis of the
coil short-circuit conditions in various parts of the force and
deformation. Transformer short circuit capacity can
be greatly improved.
2 low loss
Optimization of electromagnetic calculations, using a variety of
ways to effectively control the leakage magnetic
shielding to reduce the load loss and to avoid overheating.
High quality cold-rolled silicon steel lattice orientation of high
permeability, the use of miter joints STEP step, no
holes are not stacked on the yoke process, reduce the load loss,
load current, electromagnetic noise.
3 high mechanical strength
Six-side positioning of the body using methods to meet the
transport direction of the acceleration level is not
greater than 0.3G, the vertical direction is not greater than
0.15g.
4 ONAF system
The ONAF system is based on ONAN system, and some fans would be mounted on the wall or radiating tubes which can help transformer to cool down. the process of cooling down includes follows: the heat within the iron core and winding woul be delivered to the surface of the tank and radiating tubes by the heat conduction of oil. Then the fans would work and accelerate the air flow to speed up the process and help the transformer to cool down. Also, if the transformer equipped with fans, the capacity and working load can increase 35%.
Test equipment of 110kV Three Phase Oil Immersed Power Transformers
Strict test should be done according to IEC standard, by high technical equipments to ensure the quality and the 110kV Three Phase Oil Immersed Power Transformers.
Qualification & certifications of 110kV Three Phase Oil Immersed Power Transformers
