摘要
本文概要介绍了作者在我院电热膜工程项目中用于对电热膜玻璃管进行绝缘电阻检测的自动控制线路.并介绍了该柜的总体设计方案,各主要环节的控制线路,绝缘电阻测量仪,系统的自动检测及声、光报警电路的工作过程.
The paper briefly introduce an automatic control system for glass tube film heated by electrons of insulation resistance's measure, which was applied to our college's programe of Film Heated by Electrons, and made a total design programe of the box, the controling circuit of mains, the measuring instrument of insulation resistance,the auto-meas-uring of system and the process of working for the circuit of sound with li-ght the autoalarm.
