Professional Skills of Distribution Cabinet After-Sales Personnel: Maintenance and Repair Techniques

The professional skills of after-sales service personnel for electrical distribution cabinets can be assessed from the following perspectives:

Repair and maintenance skills.
Maintenance operation guidelines.
Observe whether the after-sales service personnel follow the standard operating procedures when performing repairs on distribution panels. This includes properly disconnecting the power supply before starting repairs, taking adequate safety precautions (such as wearing insulating gloves and using insulating tools). When replacing electrical components, they should be able to perform the task according to the correct steps. For example, when replacing circuit breakers, they must ensure that the models match, the connections are secure, and the correct parameters are set.

Maintain diversity in skills.
Evaluate their skills in maintaining distribution panels. A professional after-sales service technician should be able to perform a variety of maintenance tasks, such as cleaning the dust from the interior of the distribution panel (knowing how to prevent dust from entering the electrical components), tightening the connection screws of electrical components, checking if the temperature of the connection points of the busbars is normal, and performing functional tests on electrical components. For intelligent distribution panels, maintenance tasks should also include updating the software of the monitoring system and backing up data.
