摘要
为解决变压器油中溶解气体在线监测装置在低温环境长期运行时存在的误报率高、故障频发、维护工作繁重等问题,开展变压器油中溶解气体在线监测装置在低温条件下长期运行的常见故障分析,总结低温环境对监测装置的电子器件、材料等方面的影响,提出低温条件下变压器油中溶解气体在线监测装置的改进建议。
In order to solve the problems of high false alarm rate,frequent faults and heavy maintenance of on-line monitoring device for dissolved gas in transformer oil during long-term operation in low-temperature environment,carry out common fault analysis of on-line monitoring device for dissolved gas in transformer oil under low-temperature conditions,and summarize the impact of low-temperature environment on electronic devices and materials of monitoring device.The improvement suggestions of on-line monitoring device for dissolved gas in transformer oil at low temperature are put forward.
