The high-voltage thyristor voltage converters (types: PAD-V-G and PSD-V-G) for multiple soft start of asynchronous and synchronous motors are made as the thyristor voltage converters, intended for multiple soft start of asynchronous and synchronous motors with a voltage of 6 or 10 kV and a power of 0,315…12,5 MW, that provide a staggered soft start of several motors having different capacities via one single converter, with subsequent connection of a started motor to the mains.
The multiple converter features a set of cabinets arranged in one single cluster: a control cabinet, a thyristor voltage converter cubicle YAPN and dedicated motor selection cubicles YAVD. The motor to be started is selected by means of motor selection cubicles YAVD, which quantity is determined by the number of motors to be started. Each motor selection cubicle can commutate one or two motors.
