Overview
DJTK-BP series electronic control adopts frequency conversion speed regulation control method, which is suitable for controlling single-rope winding type or multi-rope friction type mine hoist driven by AC squirrel cage type (rotor short-circuited winding type) asynchronous motor. Rope, multi-rope mine and hoist matching design, can be matched with the newly installed hoist, and also suitable for the technical transformation of the old hoist control. It controls the starting, acceleration, constant speed, deceleration, crawling, stopping and reversing of AC asynchronous motors with a capacity of 1000KW (single machine) or 2000KWV (double machine) and below, and has complete electrical protection and interlocking.
