不接地系统 meaning in English
isolated neutral system
nus
ungrounded supply system
Examples
- Fault analysis and its precautionary measures for electromagnetic voltage transformer in ungrounded system
电磁式电压互感器在不接地系统中的故障简析及防止措施 - China ’ s 10kv distribution systems are almost grounded via the arc - suppression coil or not grounded systems
我国10kv配电网大部分是中性点经消弧线圈接地系统或者中性点不接地系统。 - Overvoltage occur frequently and causes great damage in lokv distribution network , especially in the system whose neutral - point does n ' t earth
配电网系统的过电压出现频繁，危害大，尤其在中性点不接地系统中。 - Overvoltage automatic recording device is restricted by the way which can get overvoltage from power system for a long time , and ca n ' t make great progress . because realtime recording higher voltage level power system require some special device which can get overvoltage , and some technique difficulty exist . and 10kv distribution network is used to supply power for user directly ， its distribution is extensive ， equipment is more and electric insulation level is low , it is easy that overvoltage accident occur
因为要对10kv以上更高电压等级的过电压进行实时记录对过电压获取设备的要求高，技术难度大，并考虑到10kv配电网承担着直接向用户供电的任务，分布广、设备多、绝缘水平低和过电压出现频繁，尤其在中性点不接地系统中，更易因过电压造成绝缘事故。
