韶山1型电力机车主断路器在我段运用以来,曾多次发生空心瓷瓶爆炸事故,危及行车安全,仅75年就发生瓷瓶爆炸18件。我们初步分析,空心瓷瓶爆炸烧损的主要原因是压缩空气不清洁,不干燥,在工作中空心瓷瓶内表面附着水分及杂质,而形成导电通路,使瓷瓶爆炸。我们又受到外单位用瓷瓶涂硅油的办法来提高瓷瓶绝缘强度的启发,于76年5月对空心瓷瓶进行了涂甲基硅油的试验。一、试验线路
Shaoshan 1-type electric locomotive main circuit breaker in my segment since the occurrence of hollow porcelain bottle explosion occurred many times, endangering traffic safety, porcelain explosion occurred in only 75 years 18. Our preliminary analysis, the main reason for the explosion of hollow porcelain explosion burning compressed air is not clean, not dry, in the work of the inner surface of the hollow porcelain attached to water and impurities, and the formation of conductive path, so porcelain explosion. We have been inspired by the external units with silicone oil porcelain vase to improve the insulation strength of porcelain, in May 76 on a hollow porcelain-coated methyl silicone oil test. First, the test line
