1引言一般认为,变压器油在运行中产生氢气有以下途径:(1)充油设备内部发生了故障,故障引起的高温使油热解而生成氢,但此时通常还会伴随产生其他一些故障气体(如烃类气体)。(2)油中水分在电场或铁等金属作用下发生化学反应生成氢。(3)在互感器金属膨胀器材料中的镍(Ni)的催化作用下,油中某些烃发生了脱氢反应生成氢。 1 Introduction Generally believed that the transformer oil in the operation of hydrogen has the following ways: (1) Oil-filled equipment within the fault occurred, the fault caused by high temperature pyrolysis of oil to generate hydrogen, but this time usually accompanied by some other fault Gas (such as hydrocarbon gas). (2) The oil in the water in the electric field or iron and other metals under the chemical reaction of hydrogen. (3) Under the catalysis of nickel (Ni) in the transformer metal expander material, some hydrocarbons in the oil undergo dehydrogenation reaction to generate hydrogen.
