电子设备的安全维修 | 2011-6-2 8:39:00

1．带电测量防止连电，表笔不要打滑，可将表笔磨尖或头上绑上针。
2．拆卸变频器必须等停电后直流电压消失后再进行。
3．检修带大电容电子板时，首先对电容进行自放电。
4．严禁带电插拔电路板。
5．拆卸设备时确保螺栓、设备部件摆放有序，不能造成螺栓或部件装配不全。
6．接触敏感元件电路板前人体先对地放电，尽量避免手直接接触CUVC板和静电敏感元件。
7．更换敏感元件时，电烙铁必须接地或切断电源再进行焊接。
8．检查进线熔断器是否匹配，直流进线端子及三相输出端子是否存在短路或对地现象。
9．变频器送电试验时必须检查接线是否正确，先接通24V电源，调试CUVC板，无故障后再送直流电。
10．换件后通电实验时，手不能离开电源开关，发现冒烟、打火时必须马上断电，避免故障扩大。
11．对设备检修完毕后，注明检修时间及是否正常。
12．下班前清点工具，收拾好现场，严格按要求做好检修记录
