摘要
为解决因设计、制造、安装工艺不足或运行维护操作不规范导致的胶囊密封失效、油位计显示油位不准确等问题,从大型油浸式电力变压器胶囊式储油柜的密封运行维护、油位运行维护两方面进行探讨,分析了密封失效的常见原因和检查方法,提供了摆杆式指针油位计的标定方法,并给出相应的维护建议。
To deal with the problems such as capsule seal failure and inaccurate oil level display caused by inadequate design,manufacturing and installation processes or poor implementation of operation and maintenance regulations,study is made in terms of sealed operation and maintenance of capsule oil conservators for large oil-immersed power transformers as well as oil-level operation and maintenance,analysis is conducted on common factors causing seal failure and the corresponding check methods,the calibration methods of swing rod-type pointer oil level gauges is specified,and the corresponding maintenance suggestions are put forward.
