Equipped with a transformer on load tap changers are called on load voltage regulating transformer.

On load voltage regulating transformer is the number of taps extracted from transformer winding through the on load tap changer, in guarantee not to cut off the load current situation, transform the tap position, change the effective number of turns, namely the change variable pressure ratio transformer to achieve the purpose of constant output voltage. In the transform tap energy in the process of the general use of transition resistance to limit the absorption of circulating current.

On load voltage regulating transformer is mainly used for:

1, the stability of the grid voltage at the load center, in order to improve the quality of power supply.

2, as a liaison between the two network transformer, on load voltage regulation to distribute the load between network utilization;

3, used for power with the load adjusting current and power, to improve the production efficiency of the place;

4, must strictly control voltage for the occasion, such as electronic industry, power transformer used in medicine field.

The normal conditions of use

1, the altitude does not exceed 1000mm indoor or outside the corpse;

2, maximum ambient temperature +40 the highest daily average temperature of +30 DEG C

3, the highest annual average temperature of +20 degrees temperature -25,

According to the requirements of users can provide the transformer operating in the special condition. The implementation of standards

The implementation of standards

1, GB1094 1~2, GB1094.3, 5 power transformer;

2, GB/T6451 three-phase oil immersed power transformer technical parameters and requirements.

Performance characteristics

With a full sealed oil immersed type no excitation voltage regulating transformer.
