The opening are well orientated, with sober rectangular proportions which do not overload the curve of the internal facades.
开口朝向良好，有合理的方形比例，不使内部表面的弯曲超出负荷。
A group of overload capability curve of three-phase electric traction transformer is given for use by design and operation units.
最后给出了三相牵引变压器的过载能力曲线组，供设计、运行单位使用。
The typical load curve which is selected for evaluating the overload ability of traction transformer must be reasonable, it should reflect accurately the operation status of traction transformer.
在评价牵引变压器的过负荷能力时，所选择的典型负荷曲线必须合理，使之能够正确反映线路的牵引变压器运行状况。
