摘要
进行金山热电厂线路保护检查时,在投单相重合闸的相同试验条件下,进行2条线路各相保护重合闸传动试验,第1套保护L1相、L2相、L3相及第2套保护L1相、L2相重合闸成功,第2套保护L3相重合闸失败。查找分析故障原因为线圈跳闸回路电源接线错误,正确接线后再次进行传动试验,试验结果正确。
In the process of the inspection of the lines protection for Jinshan Thermal Power Plant, doing the transmission test of auto reclosing on every phase of circuit with the same test conditions of single-phase reclosing., the results was that the test failed in the phase of L3 in the second protection, but the others all successed. To find the reason,it was that the DC power supply wiring was wrong in the operated loop. When the wiring was handled correctly and did the test in the same conditions, the results was correct.
