How to manage and maintain the trolley electric locomotive leakage protection device?

The leakage protection device on the trolley electric locomotive is a very important part of the safety system, so what is its maintenance and management?

The management and maintenance of leakage protection devices are mainly divided into three parts: recording, testing and maintenance. The first two belong to preventive means, and maintenance is the actual treatment requirement.

First of all, since the leakage protection device is put into use, its status should be recorded, and a perfect management system should be established.

Secondly, it should be tested once or twice a month under the condition of power on to confirm that the leakage protection device is in a normal state. During the thunderstorm season or a relatively harsh working environment, the number of detections should be increased appropriately. If it is detected that there is a problem with the leakage protection device, it should be dealt with in time.

The analysis and maintenance of the leakage protection device should be carried out by a professional electrician. If the cause of the problem cannot be analyzed or the maintenance is unsuccessful, it is forbidden to use methods such as directly connecting the phase wire to the ground terminal, and it is also forbidden to change the operating characteristics of the leakage protection device without permission, and it is strictly forbidden to remove the leakage protection device and force the electric locomotive to be powered.
