1通电前外观和插件检查
Machinery appearance and configuration
序号 No. 1 检查内容 check 保护装置固定良好，无松动，无明显损坏及变形 Fixed well, no loose, no obvious damage and distortion on the protection equipment 检查装置所有互感器的屏蔽层的接线均已可靠接地，装置外壳已可靠接地。 Check if the panel and all shielding cable earthed well 检查装置面板型号标示、端子号标示、装置铭牌标示正确。 Marking is clear and right, the terminal of protection equipment connected reliable. All kinds of markings and signs are right and clear 检查各插件拔、插灵活，插件和插座之间定位良好。 Appearance of insert piece and quality of welding meet the requirement of techniques 结果 Result 2 3 4 2装置上电检查 Device charging
序号 No. 1 2 3 检查内容 check 交/直流电源回路正确。 Check if the magnitude and polarity of voltage meet the requirement by multimeter before the equipment electrified with DC. 装置接通电源后，所有信号灯指示正确，主画面显示正常。 After the charging of device, all the indication is normal. 在装置正常运行情况下分别操作装置面板上各按键，检查功能正确。 Switch, keyboard should be operated flexible with right handle 结果 Result 3 装置整定值
按整定书要求将所有功能整定、参数整定、定值整定输入。
Input the setting of all function, parameters, fixed value according to the setting list. 4. 自动同期装置功能检查
