摘要
通过对轨道电路室外匹配调谐单元中电解电容与薄膜电容温度特性分析,得到温度环境应力下的电容极限温度的电气特性,并且得到温度应力变化的电容稳定性情况。
By analyzing the temperature characteristics of the film capacitor and of the electrolytic capacitor in the outdoor tuning unit of the track circuits, the paper introduces the electrical characteristics of the capacitors at limit temperature under the temperature environment stress and capacitance stability when the temperature stress changes.
