作为电工，肯定都知道三相交流电机和单相交流电机的区别，稍微留意就会发现，单相交流电机比三相交流电机多一个装备，那就是启动电容，最常见的就是各种家电，有电机的家用电器启动电容几乎必备。
简单了解一下启动电容的原理，从太专业的角度讲，或许有些不好理解，如果想了解可查这方面的专业资料。
我个人理解，启动电容就是在电机启动时给电机一个推力，让电动机能由动起来变为转起来，没有他，单相交流电机在启动时，就在原点抖动而不是转动，启动电容是两相交流电机的”先行角”，没有他，磁场就无法在转子上发力，旋转当然也就无从谈起了，从这方面讲就容易理解了。

2、可根据用户要求，生产0.6/1KV圆形导体结构或扇形导体结构的各类五芯电缆。
And this cable factory's communication cable production plant distributed throughout the country. Words in China in addition to the production of long distance communication cable and cable, fiber optic cable and comprehensive covering all plastic city for polyolefin insulated cable also had great development, many domestic manufacturers and research institutes to introduce technology and e from abroad to start producing. Welcome to contact us!
标记间隔不大于1m；12.其他结构：根据使用场合、用户要求，可提供各种形式的电缆，以满足各种敷设环境条件要求。
在一定条件下，也可用于传输2048kbit/s以上的数字信号。
。
最高传输频率分别为30MHz与100MHz。
I=800KVA÷1.732÷6KV=76.9A。
估算："容量除以电压值"：800KVA÷6KV=133。
"其商乘六除以十"：133*6÷10=79.8A。
（估算值和公式计算值有误差）。
再比如计算二次测额定电流。
公式计算：800KVA=1.732*I*0.4KV。
I=800÷1.732÷0.4=1154.7A。
估算：800÷0.4=2000，,2000*6÷10=1200A。
此口诀适用于任何等级的变压器。
