Long period of low rate of transformer load loss caused by working status

For pumping the load carried by the distribution transformer, the maximum load torque at the start, the maximum output power distribution transformer, the starting period of time, the load torque becomes smaller, the output power distribution transformer is greatly reduced. Therefore, in order to meet the requirements of pumping starter, left a large distribution transformer capacity margin. The transformer load is low rate of long-term working status, resulting in a waste of  air circuit breaker and active and reactive power losses, reducing the efficiency of the transformer, increasing the network loss. In order to reduce a pumping loss of power distribution transformers, it is necessary to use a start of pumping with a  power transformers , in the normal operation pumping unit has a small capacity, the capacity to carry out the tone volume adjustment transformer. The project studied load transfer capacity of the transformer principle is the use of  Electric transformer  capacity and loss of the relationship between the transformer losses and the relationship between the running costs, from the "road" point of view, the use of the time-domain equivalent sine wave the equivalent circuit method and frequency-domain equivalent circuit combination form of time domain - frequency domain method is applied to the transformer characteristics of deduced load transfer capacity of the transformer magnetic circuit model and the model.
