Explosion proof electrical control cabinetmaintenance and repair

1. Disconnect the power supply, check if the frame of the control cabinet has a reliable grounding, and ensure that the grounding resistance is not greater than 4 Ω.

2. There are different types of voltages on the control cabinet (DC 110V; AC single-phase 220V; three-phase AC), and the circuit must be distinguished during maintenance to prevent short circuit accidents.

3. All electrical switches on the control cabinet should operate flexibly and reliably, without significant noise. The connecting wire joints and terminals should not be loose, and the steel wire at the connecting wire joints of the moving contacts should not be broken.

4. Use a soft brush or hair dryer to remove dust from the screen board connectors and all electromagnetic switch components, and check the status and contact condition of the electrical switch contacts inside the control cabinet, the insulation of the coil surface, and the reliability of the mechanical components.

5. When replacing the fuse, the melting current should be matched with the current of the circuit.
