摘要
根据经验给出了不同形状熔断体电阻值的计算方法,提出了变截面电流密度骤变时电阻值的修正系数K。并对圆柱形插入式高压熔断体的技术要求、实测值、公式计算的阻值进行了对比,验证了计算式的合理性。这对熔断体的设计者具有一定的参考价值。
According to author＇ s experience, the fuse resistance value calculation was given, and the technical parameters, measured value and calculated value of high voltage fuse were compared, and the result verified the calcuation method. It has reference value for the fuse designers.
