What is the transformer capacity ratio? Capacity than 100%.
The ratio of the maximum capacity to the minimum capacity. The ratio of capacity to 100% is the ratio of maximum capacity to minimum capacity of 1: 1.
Have not heard, you say is not the main transformer parallel run between the main transformer and the capacity and capacity of the ratio, or the meaning of such
I made a change, you say is not: the transformer once measured capacity can be transferred to the secondary side or three times, such as three winding 50000KVA main transformer, 100/100/100, is the primary capacity can be all to the two Secondary use, you can also use all the three times, which is mainly and the main transformer winding, clip and so on factors
Transformer capacity is the power of the transformer, the capacity ratio is the power ratio, such as 1000KA transformer and 200KVA transformer is not suitable for parallel use. Capacity ratio = 5: 1 greater than 3: 1
Capacity than 100% -------- is the meaning of 1: 1 (such as 500KVA and 500KVA, 200KVA and 200KVA and so on.
Transformer side by side conditions:
① to participate in parallel operation of the transformer must be the same wiring group.
② the primary voltage of each transformer should be equal, the secondary voltage are equal. Otherwise the secondary side of the circulation caused by overload, heat, affecting the load, and increase the power loss, reduce efficiency;
③ the transformer impedance voltage (short circuit voltage) percentage should be equal, or with load after the load distribution unreasonable.
Because the large capacity of the transformer short circuit voltage percentage, small capacity of the transformer short circuit voltage percentage is small, and the load distribution and short circuit voltage percentage is inversely proportional to this will cause large transformer distribution load is small, the equipment is not fully utilized; and small transformer distribution of the load Large, easy to overload, limiting the parallel operation of the transformer with load operation.
