摘要

对于电容量精度要求高、额定容量小的金属化薄膜电容器

要保证电容量稳定

防止衰减

除了卷绕和热定型工序需要严格控制外

还必须注意后道工序对电容器容量衰减的影响

尤其是我们容易忽视的心子焊接工序。本文通过采用不同焊接功率时与焊接牢度、电容量衰减、损耗角正切之间关系进行对比试验

论证了焊接工艺对电容器的容量衰减有着不可忽视的影响。

Abstract

For metallized film capacitors with requirement of high capacitance accuracy and small rated capacity

assurance of stable capacitance and prevention of attenuation

in addition to strict control of winding and heat setting processes

also need to pay attention to the influence of subsequent processes on capacity attenuation of capacitor

especially the element welding process which is easy to be ignored. It is proved in this paper that welding process has a significant influence on capacitor capacity attenuation through the comparative test of the relationship among different welding power

welding fastness

capacitance attenuation and loss tangent.
