变压器在额定状态下的输出能力的保证值，单位用千伏安 (kVA)表示（伏安VA与兆伏安MVA不常用），由于变压器有很高运行效率，通常原、副绕组的额定容量设计值相等。 kVA是变压器中的容量，kVA为视在功率，它的大小和功率因数有关！ 1千瓦=1,000瓦特 (Watt)=1000焦耳 (Joule)/秒 (Second)。 1焦耳为1牛顿力使物体移动1米的功。 使质量位移1公斤的物体得到每秒的1米加速度之力,叫做1牛顿 (Newton)。 在电学上，千瓦时 (Kilowatt-hour)与度完全相等，只是称谓不同。 …

2017年7月17日 · 20kva ups是指ups的额定功率是20kva。ups的额定功率有两种表示方法：视在功率（单位va）与实际输出功率（单位w），由于无功功率的存在所以造成了这种差别，两者的换算关系为：视在功率*功率因数=实际输出功率
