如果消弧线圈的容量

如果消弧线圈的容量不超过变压器额定容量的50% ,那么便可以满足变压器2小时过负荷30%的规定。对于Y/ Y/△接线的三线圈变压器,额定容量分配有时为100% 33.3% :100% ,为满足变压器2小时过负荷30%的规定,则消弧线圈的容量不能大于变压器额定容量的33.3%。通过上面的讨论可知,消弧线圈的容量不应超过变压器容量的50% ,并不得大于三线圈变压器的任一线圈的容量。
If the capacity of the arc suppression coil does not exceed 50% of the rated capacity of the transformer, it can meet the requirement of 30% over-load of the transformer in 2 hours. For Y/Y/Delta connected three-coil transformer, the rated capacity allocation is sometimes 100% 33.3%:100%. In order to meet the requirement of 30% over-load of transformer in 2 hours, the capacity of arc suppression coil should not be greater than 33.3% of the rated capacity of transformer. From the above discussion, it can be seen that the capacity of arc suppression coil should not exceed 50% of the transformer capacity, and should not exceed the capacity of any coil of three-coil transformer.
