With working experience, the author has summarized the test methods of short circuit and overload protection of non-inherently short-circuit proof transformer and fail-safe transformer.
作者结合工作心得，对非固有耐短路、无危害式安全变压器的短路和过载保护测试方法进行了总结和归纳。
When electric power coupling transformer at input current is less than rated value, public winding can be also overload.
电力自耦变压器在其输入电流均小于额定值时，其公共绕组也可能过负荷。
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。
The overload capabilities of transformer can be increased by monitoring and controlling the winding temperature and the necessary durability of the transformer can be ensured.
通过监控绕组温升，从而使得变压器能够最大限度地发挥其过载潜力同时又保证必要的寿命。
The transformer is able to operate under the conditions of normal overload and accident overload.
变压器可以在正常过负荷和事故过负荷的情况下运行。
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。
For any level of transformer protection, air-cooled system can be configured (af), to improve short-term overload capacity, to ensure safe operation.
对于任何防护等级的变压器，都可配置风冷系统(AF)，以提高短时过载能力，确保安全运行。
