1、A 220V single-phase distribution board is provided in each individual unit. 380V 3-phase is also available.
2、Able to directly control AC 50Hz, 380V asynchronous motor with the protection of overload, phase-failure and voltage-absent.
3、Secondly, the paper designs and realizes the two level variable frequency heating power supply with line of 380V.
4、每单位内安装一个220V单电配电箱，也可提供380V三相电源。
5、The way of neutral grounding in 380V LV distribution system was introduced and the characteristics of grounded and non grounded systems were analyzed.
6、It is analyzed that low voltage 660V power supply has superiorities over that of 380V, such as high power transmission ability, low loss of power and improvement of protection and power quality.
7、With the short-circuit test system above, the 380V/25A HTSFCL was successfully tested. The results show that the short-circuit test system can satisfy all the requirements to test HTSFCL.
8、可控制交流50Hz，380V，三相异步电动机的直接起动停止，并具有过载和 断相及失压保护。
9、分析了低压660V供电较380V供电的优越*，如提高了线路的输电能力；在电缆长度和截面不变的情况下，其输送功率扩大3倍；
10、利用上述的这套短路试验系统，对380V／25A高温超导限流器成功地进行了短路试验，实验结果表明：这套短路试验系统能够很好地满足测试高温超导限流器限流能力的要求。
