x landlonyo线电压(line voltages)三相电路中A、B、C三相引出线相互之间的电压，又称相间电压。不论星形接线还是三角形接线，三个线电压分别是UAB、UBc和UcA，如图所示。x(A相)A┌───┐│(C相)C│└───┘(A相)(e相)洋 (B相)YC 三相电源的线电压 线电压与相电压间的关系是(以电源侧为例):①对三角形接线，线电压就等于对应的相电压;②对星形接线，则线电压与相电压之间的关系为UAB一UAN一亡BN、亡Bc~亡BN一亡cN和亡cA~亡cN一亡A、。 若三相电源的相电压为正序(负序)对称组，则三相线电压也为正序(负序)对称组。这对三角形电源(或三角形负载)是不言而喻的。对星形电源(或星形负载)，以正序对称组为例，有 氏B一么N一亡州一了飞-亡AN/3扩 氏C一么N一氏N一丫丁氏N/30。 亡e、一亡eN一亡AN一丫了亡cN/30。可见，在对称三相电路中，不论三相电源或三相负载，在三角形接法时有UL一U。，在星形接法时有UL~了万~u。，这里，uL和u。分别为线电压和相电压的有效值。
