1 热电站6kV 备用电源自投装置原理洛阳石化总厂热电站6kV 母线共有3段,如图1所示。正常运行时,6kV-段由1#电抗器带,6kV 二段由2#电抗器带,备用段不带电,高备变热备用。当6kV 一段(或二段)由于某种原因失电后,通过备用电源自投装置,大备1开关、601B(或602B)开关自动合闸,高备变投入运行,带6kV 一段(或二段)运行,保证厂用电不失电。
1 6kV power plant thermal power plant self-throwing device principle Luoyang Petrochemical Plant thermal power station 6kV bus a total of 3 sections, shown in Figure 1. Normal operation, 6kV-section by the # 1 reactor, 6kV Sec section by the 2 # reactor with spare section uncharged, hot backup spare. When 6kV section (or two sections) for some reason after the loss of power, through the backup power supply from the device, a large 1 switch, 601B (or 602B) switch automatically closing, high standby into operation, with a 6kV section Section) operation, to ensure that the plant electricity loss.
