Maintenance precautions for distribution cabinet

‌

In terms of electrical aspects, the first step is to check the model of the parts based on the technical drawings, verify the overlap torque, and identify them (which is a laborious task). Pay attention to whether the creepage distance and phase to phase distance meet the standards, and whether the wiring meets the company's process requirements. Then check if the main circuit and control circuit are correct. This circuit mainly uses a multimeter to measure the circuit. The distribution cabinet should be installed and powered on to test whether the electrical function meets the drawing requirements. If qualified, an inspection report must be issued. If it is qualified, it will be labeled and issued. If it is not qualified, it will be returned for correction.

Precautions for installation of distribution cabinet:

During the maintenance process, there must be a dedicated person to supervise.

2. Check the power supply before work.

3. Maintenance personnel should be familiar with and operate the electrical and mechanical interlocking of the entire distribution cabinet.

4. During maintenance, it is necessary to have a detailed understanding of which lines are powered by dual wires.

5: When repairing the busbar, the remaining charge in the circuit should be completely discharged.
