The Design Principle and Application of Thermally Protected Metal Oxide Varistor TMOV

Article Preview

Abstract:

Metal oxide varistors referred to as MOV were widely applied due to its excellent non-linear volt-ampere characteristic. In spite of its predominant function and using, MOV is always failed in value due to the increased temperature of MOV itself under an applied external field. The varistors assembly with an fusible alloy type thermal cutoff (called TMOV as follows) was designed in this paper, and it can make MOV avoid over-heat from degradation, failure and thus can prevent from fire hidden trouble, which was confirmed by experiments. It is really a very important technological improvement and breakthrough in over-heat protective field of MOV.
