摘要
绞车原电控系统采用的是转子串电阻调速,电阻消耗大量的能量,电阻变红、变形,造成了不安全隐患,经技术改造为BPDK-ZN-01S型变频提升机电控系统。
The original electric control system of the hoister adopted rotor series resistance speed regulation, the resist- ance consumes much energy, and the resistance turns red and deformed,leads to hidden trouble. By technical transforma- tion, it has become thelectric .control system of BPDK - 01S type conversion hister.
