め要約のデータは記録されません。(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.
Description
第１図は単相負荷だけの場合の考案の実施例である。
１は電源変圧器の第２種接地線、２は単巻変圧器、３は
平衡用の静電蓄電器、４は対象回路全体の静電容量、５
は対象回路全体の絶縁抵抗、６は零相変流器、７は保護
継電器あるいは監視装置。
第２図は多数負荷をまとめて保護あるいは監視を行う場
合の実施例である。
１から７まで第１図と同じである。FIG. 1 shows an embodiment of the invention in the case of only a single-phase load. 1 is the second type grounding wire of the power transformer, 2 is the autotransformer, 3 is the balancing electrostatic capacitor, 4 is the capacitance of the entire target circuit, 5
is the insulation resistance of the entire target circuit, 6 is the zero-phase current transformer, and 7 is the protective relay or monitoring device. FIG. 2 shows an embodiment in which multiple loads are collectively protected or monitored. 1 to 7 are the same as in Figure 1.
