标题: 电源短路测试次级线圈匝数

The percentage ofturns to be short-circuited shall be approximately equal to the short-circuitvoltage expressed as a percentage of the rated supply voltage. The specimenwith the short-circuit shall then be checked as follows. The unloaded transformershall be supplied at 1, 1 times the rated input voltage at ambient temperatureand the input power (watt) measured shall be equal to thevalue of the rated output with a tolerance of ±20%. During the measurement, no adjustments shall bemade.

短路测试时的次级线圈匝数确认：当次级短路时测得的输入功率=额定输出功率±20%偏差内

各位懂的专家，上面那段标准以这样理解对不对？

怎么感觉是短路匝数=总匝数×短路电压/额定电压，后面的如你所理解的一样哪本标准的要求？哪章哪节？

我和你的理解是一样的！
当次级的部分圈数短路后，在1.1倍额定输入电压下，产品的输入功率应该在额定输出功率±20%偏差内
