6、于运输的振动或保管不当而造成机械性能变化，需要作一般的检查和调试，检查和调试均可按插件接线图以插件为单元进行。3.1一般检查装置接线应符合原理接线，各元件规格正确，装配完好,焊接坚固牢固，接插可靠。各导电部分对外壳（或框架）以及电气上无联系的各电路之间的绝缘电阻，应不小于100MΩ（用500V兆欧表测量）。3.2继电器的检查检查1YQJ1～9、2YQJ1～9、3YQJ1～9的动作电压为30%～70%额定电压，复归电压为30%～80%额定电压(1YQJ7～9、2YQJ7～9、3YQJ7～9的返回电压为不小

7、于5%额定电压)，动作时间不大于10ms.3.3装置整组检验3.3.1按装置原理图，通电检查各引出端子上触点的闭合和开断状况，要求接线正确，接触良好。3.3.2在端子101和132上加上可调电压（+）、（—），检查1YQJ1～9的动作情况，同时面板上“I母电压”灯亮，在端子102和132上加上可调电压（+）、（—），检查1YQJ1～6的复归情况，检查1YQJ1～9各输出触点的通断情况，应符合装置原理图的要求。3.3.3在端子201和232上加上可调电压（+）、（—），检查2YQJ1～9的动作情况，同时面

8、板上“II母电压”灯亮，在端子202和232上加上可调电压（+）、（—），检查2YQJ1～6的复归情况，检查2YQJ1～9各输出触点的通断情况，应符合装置原理图的要求。3.3.4在端子301和332上加上可调电压（+）、（—），检查3YQJ1～9的动作情况，同时面板上“III母电压”灯亮，在端子302和332上加上可调电压（+）、（—5-5ZYQ-824电压切换箱使用说明书），检查3YQJ1～6的复归情况，检查3YQJ1～9各输出触点的通断
