可以理解为额定输入功率即认为是铭牌标示上的功率。对吗作者: craigyu 时间: 2012-10-11 21:23

看来你功课确实都还给老师了,实在功率是炮哥造出来的作者: guanito 时间: 2012-10-12 06:54
即例2000wX1.15倍,用2300w检测即可作者: yinke 时间: 2012-10-12 10:00
举个例子,假如一器具额定参数为:220-240V,2000W的话. 2000 W是代表在电压为230V下的的功率,但是做11章正常温度测试的时候要换算到240V下的功率后,再乘1.15,而不是2000乘1.155 H- h( ?' Z3 H( d* [2 p2 g n
