three phase supply meaning in Chinese
三相供电
Examples
- Gb1094 . 5 - 85 power transformers part 5 ability to withstand short circuit only applies to power transformers , not to balanced transformers . if short - circuit test on balanced transformers can be performed by means of single phase supply instead of three phase supply , and other special transformers can also be done in this way , so it is very significant to improve test capacity of transformer laboratory in our country
变压器的短路强度只能通过短路试验来验证，国家标准gb1094 . 5 - 1985 《电力变压器第5部分承受短路的能力》只适用于电力变压器，对平衡变压器等特殊变压器并无具体规定，对于平衡变压器，如果可以用单相电源预先短路法模拟三相电源的短路试验，那么其它特种变压器的短路试验也可以参照进行，这对提高我国变压器试验室的试验能力具有重要意义。
