摘要
工厂在开关柜组装中发现ABB公司生产的S503型断路器所配操作机构,分合角度不易到位,以及铝合金导轨易于脱落现象,给质量带来了不利,因此工厂进行了改进设计,之后使用情况良好,供同行及用户参考。
During the assembling of switchgears the operating mechanism complete with S503 type circuit breaker, which is produced by ABB Company, is found to be difficult to hold in place at the right open-close angles, aluminum alloy guides run off with ease, thus having an effect upon its quality. So version design was made for it with some success, being in good working order, for customers information only.
