<p>PURPOSE:To reduce the number of gas monitoring section and necessary machine while ensuring power interruption range of bus or line at the time of maintenance or inspection by integrally setting line machines, bypass disconnector and an auxiliary bus disconnector in a first gas monitoring section whereas setting only a main bus disconnector in a second gas monitoring section. CONSTITUTION:A line disconnector 4, a bypass disconnector 6 and an auxiliary bus disconnector 8 are integrally set in a first gas monitoring section by employing insulating spacers 6a, 6b, 6c which can communicate gas freely, whereas only a main bus disconnector 7 is set in a second gas monitoring section. Consequently, construction of each machine and associated monitoring units can be simplified as compared with conventional system where each machine is set in individual gas monitoring section. Furthermore, since first and second gas monitoring sections are set independently at the sides of main bus 1 and auxiliary bus 2, power interruption is required at only one gas monitoring section at the time of maintenance or inspection of machine.</p> |
