The site required is much smaller. In general, both circumstances lead to a considerable cost saving with complete substation projects when SF6-insulated high voltage switchgear is used.ENGR. RIAZ AHSAN BAIG
1、中试控股交流耐压前测量GIS的绝缘电阻,A、B、C三相应分别逐项进行(测量一相时另外两相接地)。 2、加压试验:(测量一相时另外两相接地)首先加压 73kV(设备最高相电压110/√3×1.15=73kV)5-15分钟老练试验,无问题后升至126kV(设备最高线电压110×1.15=126)1-5分钟老练试验,然后升至230kV/1min耐压试验。...
