Common Fault Treatment Of Mining Trolley Narrow Gauge Locomotive Locomotive

We know that there are a lot of mining transportation equipment, and the stringing electric locomotive is a relatively safe and commonly used traction equipment in rail transportation vehicles, but as a mechanical equipment, some problems in the process of work are relatively normal, but they will delay the progress of the project if not handled in time. Today, we will introduce the common troubleshooting of mining trolley narrow gauge locomotive.

The most common fault is the occurrence of electrical circuit, which directly leads to the unstable starting, running and power braking of trolley narrow gauge locomotive. So as for the electric circuit problems caused by the trolley narrow gauge locomotive, it can make you quickly check out the problems, so as to ensure the quiet and stable operation of the mine stringing electric locomotive. The main fault of the electric circuit is formed by the open circuit, short circuit, grounding and wrong connection.

1. Failed to start normally. Check whether the positive automatic switch is closed, whether the ground wire is normal, whether the adjacent wire of the pantograph is excellent, and whether the plug between the driver control panel and the frequency converter is plugged in.

2. The alarm light is on. It may be caused by over-current, over-voltage, under voltage, short circuit, grounding, over temperature and other problems. First, press the reset button, then find out the fault, find out the cause, and carry out punishment.

3. The electric brake is not good. It may be that the brake resistance is open, the IGBT module used for braking is broken or the wiring is poor, and the brake control circuit is damaged. The key points of punishment: connect the brake resistance, check the module and wiring or replace the brake control board.

The above is the common faults of the mine trolley electric locomotive. I hope you can understand and solve the problems timely and effectively, which not only improves the working efficiency but also saves the maintenance cost, so I hope you can master it!
