摘要
厂用电的安全可靠直接关系到发电机组的安全运行。为确保厂用电的安全可靠,通常,对重要厂用电母线均设两路电源供电,两路电源之间设有快切装置,当一路电源跳闸后,另一路电源通过快切装置自动快速投入,保证了重要厂用电母线供电的可靠性。本文在分析厂用电母线进线电源开关跳合闸回路基础上,叙述了快速判断厂用电快切跳合闸回路中是否存在问题的方法,若有问题及时加以解决,从而提高厂用电切换的成功率。
Reliability of plant power supply has influence on generation unit safety operation. Generally, there are two power supplies in the bus to ensure the stability of plant power supply. There has a quick switching device between two power supplies which ensure that when a supply trip the other can operate quickly. The paper presents the method to check the problem in tripping and closing circuit.
