摘要
目前主变备自投装置没有考虑中低压侧接有小水电源后的逻辑判据,当主变备自投投入,存在故障主变跳开后再次投入的问题。通过一起典型备自投装置误动分析,提出对中低压侧接有小水电源的主变备自投装置逻辑判据进行修改的对策,保证备自投安全、可靠运行。
At present the main BZT device without consideration of low voltage side connected with a small water power after the logical criterion, when the main BZT inputs, fault of main transformer tripping again after into the problem. Through a typical auto-switching malfunction analysis, put forward to the low pressure side is connected with a small water power to main BZT device logic using the modified measures, to ensure safe, reliable operation of bats.
