Abstract
Description
本工程では、油入電気機器内で使用されている絶縁油中に含まれる、水素ガスと、メタン、エタン、エチレン、アセチレン、炭素数が3または4である炭化水素、一酸化炭素、二酸化炭素、酸素および窒素からなる群から選択される少なくとも1種のガスとを分析する。炭素数3または4の炭化水素としては、例えば、プロパン、プロピレンおよびブタンが挙げられる。これらの内、特に、アセチレン、水素、メタン、エタン、エチレンおよび一酸化炭素を分析することが好ましい。
本工程では、放電発生の有無によらず絶縁油中において水素を発生させる原因となる原因物質を分析する。
本工程においては、油中ガス分析工程の分析結果および原因物質分析工程の分析結果に基づいて、放電発生の有無を診断する。なお、放電発生の有無は、油中ガス分析工程の分析結果と原因物質分析工程の分析結果とに基づいて総合的に診断される。
