株洲冶炼厂锌电收尘,原采用CC—18Z型机械整流器,操作维护复杂,维修工作量大,噪声大,效率低;同时在运行中,产生一种有害气体——臭氧,影响工人的身体健康,备品备件供应困难,有时影响生产。该厂八车间职工在党支部领导下,组成以工人为主体的三结合试验小组,从73年元月开始经过五个月的时间,成功地将一台机械整流改成了可控硅控制——高压硅堆整流,经过一年多的运行,性能良好,74年12月至75年9月期间在第一台的基础上又
Zhuzhou Smelter zinc dust, the original use of CC-18Z-type mechanical rectifier, operation and maintenance complex, large maintenance workload, noise, low efficiency; at the same time in operation, produce a harmful gas - ozone, affecting the workers body Health, spare parts supply difficulties, and sometimes affect the production. Under the leadership of the party branch, the eight factory workers of the plant formed a three-in-one experimental team with workers as the main body. After five months from January of the first half of 1973, a mechanical rectifier was successfully converted into a thyristor control system. - High-voltage silicon rectifier, after more than a year of operation, good performance, December 74 to 75 in September on the basis of the first
