The packaged converters for individual soft start of asynchronous and synchronous motors of voltage 6 kV and power 0,315 — 2,2 MW are executed as single highly moisture- and dustproof space-saving cabinets.
The packaged converters are intended for soft start of one motor only and are fully functional devices. Hence there is no need for using the additional cubicle switchboards to supply power to thyristor voltage converters, and power supply system of a substation, shop or plant does not to be altered.
They provide total motor control and protection both during acceleration and in operating mode.
A single hermetically sealed cabinet contains a set of all necessary power switches, protective elements, thyristor voltage converter and control system.
