Information

The control cabinet is to assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on the screen according to the electrical wiring requirements. The layout should meet the requirements of the normal operation of the power system, which is convenient for maintenance and does not endanger people. And the safety of surrounding equipment. During normal operation, the circuit can be switched on or off by means of manual or automatic switches. So how much do you know about its maintenance knowledge? Let's follow the editor of the customized explosion-proof control cabinet to have a simple understanding!
1. Disconnect the power supply, check whether the frame of the control cabinet has a reliable grounding, and make the grounding resistance not greater than 4Ω.
2. There are voltages of different natures on the control cabinet (DC 110V; AC single-phase 220V; three-phase AC). It is necessary to distinguish the circuit during maintenance to prevent short circuit accidents.
3. All electrical switches on the control cabinet should act flexibly and reliably without significant noise. There should be no loosening of the connecting wire knots and terminals, and there should be no breakage of the steel wire at the connecting wire knots of the movable contact.
4. Use a soft brush or air blower to remove the dust on the screen board plug-in unit and all the electromagnetic switch parts, and check the state of the electrical switch contacts in the control cabinet, the contact condition, the insulation of the coil surface and the operation of the mechanical parts are reliable.
5. When replacing the fuse, make the fusing current match the current of the loop.
The above is the editor of the customized explosion-proof control cabinet: about the maintenance and maintenance of the control cabinet.
