Abstract
The invention discloses an internal contracting brake controlling system and method. According to the invention, an alternating-current high voltage is output to a transformer through a power module; the alternating-current high voltage is transformed into an alternating-current low voltage and output to a rectifier bridge through the transformer; the alternating-current low voltage is rectified into a direct-current low voltage and output to an internal contracting brake system through the rectifier bridge so as to control an internal contracting brake of an internal contracting brake system. According to the scheme, the alternating-current high voltage is converted into the direct-current low voltage which is then output to the internal contracting brake system to control the internal contracting brake, so that the vortex phenomenon produced in the manner that an internal contracting brake is controlled by an alternating-current high voltage directly is overcome and the maintenance cost is reduced; in addition, a heavy current is realized, the electromagnetic force is enhanced and the braking force of high-power rotating equipment is increased; furthermore, the problems of large calorific value and high loss of a complete machine caused by direct use of a direct-current voltage are avoided, the function loss and the consumption cost of the complete machine are reduced and the operation reliability and the working efficiency of the internal contracting brake are increased.
