220kv Double Winding off Circuit Tap Changer Power Transformer

The main technical innovation points

Significant energy-saving effect, the load loss of only 25%-35% of the conventional product;

Superior performance, product safety, reliability, environmental protection;

High mechanical strength, strong ability to withstand short circuit, safe and reliable operation;

Low noise, easy installation, maintenance free

Product description

The voltage transformer is transformed into a system or the voltage required to load, the transmission

and distribution of electricity, the transformer instead of transformer silicon steel sheet core and widely

used in power distribution system outdoor.

A lot of the operation of this product can achieve good energy-saving effect and can reduce the pollution

of the atmosphere, the product is especially suitable for electric power shortage and load fluctuation and

difficult to carry out routine maintenance area, due to the transformer adopts fully sealed structure, the

insulation oil and medium without air pollution, so it can be run in a humid environment in the power

distribution equipment, is the city and countryside distribution network in the ideal.

Structural characteristics

Iron core of transformer with amorphous alloy strip coil system, idle loss ratio of S9 type transformer is

reduced by about 80%, than the JB/T10318 specified value low around 25%, low by copper coil, enhance

the ability to withstand short circuit in transformer, connection using Dyn11, reduce the impact of harmonics

on the grid, improve power quality; the sealing structure of fuel tank and the box cover are welded into a whole,

prolong the service life, avoid repair; transformers using vacuum oiling, can be completely ruled out coil in the

bubble, stable insulation performance; full wave lightning impulse test each transformer factory before the peak

voltage is higher than the national standard of 25%, to ensure the safe and reliable operation of the transformer.
