Maintenance of Control Cabinet 1.断开电源,检查控制柜的机架是否有可靠的接地,并使接地电阻不大于4Ω。 1. Disconnect the power supply, check whether the rack of the control cabinet is reliably grounded, and make the grounding resistance not more than 4. 2.控制柜上有不同性质的电压(直流110V;交流单相220V;三相交流),在维修保养时必须分清电路,防止发生短路事故。 2. The control cabinet has different voltage (110V DC; 220V AC single-phase; three-phase AC), so it is necessary to distinguish the circuit during maintenance to prevent short-circuit accidents. 3.控制柜上的全部电器开关,应动作灵活可靠,无显著噪声,连接线结头和接线柱应无松动现象,动触头连接线结头处钢丝应无断裂现象。 3. All electrical switches on the control cabinet should operate flexibly and reliably, without significant noise, no loosening of the connecting wire and the connecting post, and no breaking of the steel wire at the connecting wire of the movable contacts. 4.用软刷或吹风清除屏板插件和全部电磁开关零件的积尘,并检查控制柜内电器开关触头的状态,接触情况,线圈外表的绝缘以及机械部件的动作是否可靠。 4. Use soft brush or blowing to remove dust from screen plug-in and all electromagnetic switch parts, and check the status of electrical switch contacts in the control cabinet, contact conditions, insulation of coil exterior and reliability of mechanical parts.yuesaoq.75ix.com zhuceq.75ix.com huashiq.75ix.com lvhuab.75ix.com banjiab.75ix.com yinshuab.75ix.com 5.更换熔丝时,应使熔断电流与该回路的电流相匹配。 5. When replacing the fuse, the fuse current should be matched with the current of the circuit. |
