The Tunneling Diesel Locomotive Character
- Sep 06, 2017 -

When metro and tunnel powered diesel locomotives , when the diesel locomotive’s working current exceed  PLC setting threshold of more than 3 seconds, then trigger the tunnel diesel locomotive’s heavy-load protection function, alarm system will start alert drivers care and reduce the gear, at the same time, PLC to control frequency converter output frequency from the currently running frequency of 2 hz per second speed is reduced, until the output current resume below the threshold. When the flow failure is eliminated, the system is automatically restored to the operating position set by the operating handle.
