  1. The problem about neutral - point - grounding mode is an all - around technical problem which associated with not only power system reliability , insulation coordination , electromagnetic interference , but assault safety 。 in china , the neutral grounding modes of the 10kv net involved of none grounding, grounding by arc suppressing coils, resistance grounding or reactance grounding in the past 。 with the development of civic power network , low resistance grounding mode was used to restrain the over voltage, particularly in guangzhou, shanghai , beijing , and zhuhai etc. it was reported that the over - voltage level of low resistance grounding mode is lower than that of arc suppressing coil mode, but the operation carried out the other way 。 at substations in guangzhou and shanghai it was found that the low resistance grounding mode is successful 。 but in some areas , such as zhuhai , substations grounding with low resistance revealed some problems , including power supply reliability rapidly dropping , transmitting line often tripping ; and person safety being threatened 。 so interiorly the grounding mode selection of the 10kv network was disputed, which mainly focused on the fault form of 10kv net grounding, the apply area of suppressing arcing coil grounding mode, power supply reliability level of the two modes, person safety, communication interfere and the workload of maintenance

    爭議點主要是在10kv網接地故障的形式、消線圈接地的應用范圍、兩種運行方式供可靠的高低、人身安全、通訊干擾和運行維護工作量等諸多方面。 11 17本論文就是針對以纜為主的城區10kv網中點接地方式的選擇問題進行研究。論文首先對10kv網的中點運行各種方式進行分析,比較各方式的點,然後以重慶儲奇門變站10kv網的實際參數來建立數值計算模型,在考慮了網接地流變化、中阻取值大小、接地點接地阻值變化等多種影響因素的情況,對中點經消線圈接地和經小阻接地方式網的過平和接地點短路流大小進行了數值計算,其計算結果與科院所作現場試驗進行了比較。
  2. The constriction performance of vacuum electric arc at high current levels depends on the contact material and its operational principle. axial magnetic field ( amf ) contacts can prevent the vacuum electric arc from shrinking in the vacuum interrupters

    在大真空的收縮取決于觸頭的材料和工作原理,在真空滅室中縱向磁場( amf )觸頭能夠阻止真空收縮。
