Description

Industrial control transformers

The ambient air temperature is – 5 ° C to + 40 ° C, and the average value in 24 hours does not exceed + 35 ° C;

The sea level of the installation site shall not exceed 200m;

Functional features editing and broadcasting

characteristic

1. Anti interference effect: for example, after passing through the isolation transformer with Y / △ wiring, it can prevent the transmission of some harmonics;

2. Impedance transformation function: increase the system impedance to make it easy for the protection devices to cooperate;

3. Function of stabilizing system voltage: such as reducing the impact on system voltage when starting heavy load equipment;

4. Function of preventing system grounding: when single-phase grounding occurs at the load side of the isolation transformer, it will not cause single-phase grounding of the whole system (above the satons isolation transformer);

5. Reduce short-circuit current: when a short-circuit accident occurs at the load side, limit the short-circuit current of the system.
