基本组成
交流器主要有四部分组成:(1) 电磁,包括吸引线圈、动铁芯和静铁芯；(2)触头,包括三组主触头和一至两组常开、常闭触头,它和动铁芯是连在一起互相联动的；(3)灭弧装置,一般容量较大的交流器都设有灭弧装置,以便迅速切断电弧,免于烧坏主触头；(4)绝缘外壳及附件,各种弹簧、传动机构、短路环、接线柱等。
工作原理??当线圈通电时,静铁芯产生电磁吸力,将动铁芯吸合,由于触头是与动铁芯联动的,因此动铁芯带动三条动触片同时运行,触点闭合,从而接通电源。当线圈断电时,吸力消失, 动铁芯联动部分依靠弹簧的反作而分离,使主触头断开,切断电源。 使用接法??一:一般三相器一共有8个点，三路输入，三路输出，还有是控制点两个。输出和输入是对应的，很容易能看出来。如果要加自锁的话，则还需要从输出点的一个端子将线接到控制点上面。

在从动力到新能源动力的转型中，混合动力技术是个被市场所接纳并迅速推广的。自从丰田从1997年推出代普锐斯以来，混合动力技术就被众多汽车企业当作迈向新能源的步加以发展。时至，普锐斯已经发展成为系列车型，各大汽车企业也都推出了各自的混合动力车型。混合动力的技术也开始逐步细化为并联式混合动力、串联式混合动力以及混联式混合动力三种结构形式。但是无论是那一种结构形式，电动机在混合动力车型上的作用都还只是局限于动力上，电动机的动力来源依旧是内燃机，其作用更多的在于内燃机不必要的燃料损失。所以根据电动机出力的不同混合动力车型在坊间又被分出了一个轻度混合动力的类别。的混合动力车型很少有纯电动，即使是近年来出现的可以实现纯电动行驶的车型，其电动下的续航里程也仅仅为十几公里。可以说，混合动力车型的出现是内燃机动力朝着电动机动力进化的一小步，本质上依旧是一台的内燃机汽车。
第二，机组性和可靠性问题。低风速风电场风况复杂多样，尤其此类地区湍流强度、入流角、风切变等风况参数具有性，对机组性和可靠性具有重要影响，目前国内无相应的规范，会给项目机组选型带来了一定的困扰。
