　　(3)瞬时电流整定值≥1.1X(Ijx+k1kIedm)Ijx线路计算负载电流;k1电动机起动电流的冲击系数，一般取k1=1.7-2;k电动机起动电流倍数;Icdm一台电动机的额定电流220kV断路器开断的额定电流选取,就是课本上的短路电流计算,额定开端电流是。　　上图为主副绕组接线方式，及改变转向的两种连接方法，单相电动机一般副绕组电阻值比主绕组略大。即用万用表R档测量电阻大的为副绕组线圈，小的为主绕组线圈。电容30UF为运行，200UF为起动。二、结构原理电容分相电动机的转子绕组是浇筑成型的鼠笼式，定子上饶有2组空间上相差90°的启动绕组B和工作绕组A，从而电角度ω为90°的两相交变电流，保证磁场的形成条件。　　电压互感器vv接线，由两只单相电压互感器组成的V-V形接线时，其一次侧是不允许接地的，因为这相当于系统的一相直接接地。但对这样的单相电压互感器，哪一个引出端当A，哪一个引出端当X都无所谓，只是需要将电压互感器的二次引出端和一次相对应就行，而应在二次中性点接地，如下图所示。

　　2.种类及特点时间继电器的种类很多，主要有空气阻尼式、电磁式、电动式和电子式。①空气阻尼式时间继电器又称为气囊式时间继电器，它是根据空气压缩产生的阻力来进行延时的，其结构简单，价格便宜，延时范围大（0.4～180s），但延时度低。

韩国AUTOMA,AS80,AS100,制造厂家　　注意事项：a．试验时应先去磁（可加交流电压平缓升降几次），然后将电压逐渐升至励磁特性曲线的饱和点即可停止；b．如果该绕组励磁特性的饱和电压高于2kV，则现场试验时所施加的电压一般应在2kV截止，避免二次绕组绝缘?。　　可是这样合计为铁素基体，脆性很大，高温强度低，限制了其应用。为了合金在1200-1300℃的抗氧化性能，出一些高温下能形成Al2O3的高温合金，国外典型合金有HaynesAlloy214、эп747、Inconel602、Inconel603等。重庆仪表材料在国外合金基础上，通过Cr、Al含量，并采用晶界精华和强化技术，研制出一种新型抗氧化高温耐热合金3YC52，其主要原因是在高温下除形成Al2O3、Cr2O3的混合氧化膜外，还能形成致密、单一α-Al2O3保护膜。

 　　根据“化工自控设计技术规定”，在测量稳定压力时，最大工作压力不应超过测量上限值的2/3；测量脉动压力时，最大工作压力不应超过测量上限值的1/2；测量高压时，最大工作压力不应超过测量上限值的3/5。一般被测压力的最小值应不低于仪表测量上限值的1/3。　　15、电压指数上升率dv/dt：继电器的输出元件能够承受的不使其导通的电压上升率。16、工作温度：继电器安规范安装或不安装散热板时，其正常工作的环境温度范围。功率固态继电器的特性参数包括输入和输出参数，下面以北京科通继电器总厂生产的GX-10F继电器为例，列出输入、输出参数，详见表1，根据输入电压参数值大小，可确定工作电压大小。
