容抗同样会引起电流与电容两端电压的相位差。Xc=1/(ω*C)ω---角(单位:弧度/每秒rad/s)C---电容(单位:法拉F)Xc=1/(2*π*f*C)f---(单位:赫兹Hz)C---电容(单位:法拉F)角---在简谐振动中,的2π倍叫角。

[3]继电器的接点多种多样,可分为单组接点继电器和多组接点继电器两大类。其中,单组接点继电器又分为常开接点(动合接点,简称H接点)、常闭接点(动断接点,简称D接点)和转换接点(简称Z接点)三种(图3)。多组接点继电器既可以包括多组相同形式的接点,又可以包括多组不同形式的接点。

口碑好的韩国电源powerplaza,PS25-24-3R3制造厂家 以此类推就是表示能够控制三个线路的通断,一般在380V的三相电机上能够用到。可能会有朋友会问那2P和1P+N有什么区别呢,N一般表示零线,而1P只能控制一个线路的通断,所以当短路时,2P的那个零线能够断开,但是1P+N的不能断开。 三相绕组可为星形或者三角形联结,相绕组由支路构成,支路有若干线圈组构成,线圈组又有分线圈构成。并且还有单双层之分。(这是对于双速电机来说的)一般来说,按照功率来分4千瓦以下的电机一般接成星形,大于4千瓦的电机接成三角形。
