Synchronous motor exciter system VTE series

Thyristor exciters series VTE, VTP are provided for automatically regulated DC supply of synchronous motors excitation windings with capacity up to 12500 kW, upon their direct and reactor start, synchronous operation and in emergency modes. Exciters are produced for rated current of 200, 320, 400, 630, 800 and 1000 А, rated voltage from 24 up to 300 V. Exciters for 200, 320 and 400 А current have natural air cooling, and forced air cooling with built-in blowers for 630, 800 and 1000 А current. Characteristics and benefits: rated currents: from 200 up to 1000 А; rated voltages: from 48 up to 230 V; power unit — thyristor rectifier, made with 3-phase «bridge» or «neutral» circuit; cooling: natural air up to 400 А (incl.); forced air more than 400 А; digital control system; compliance with GOST 24688-81 and GOST 18142.1-85 requirements; can be applied instead of formerly released exciters series TV, TVU, VTE, ТЕ8, V-TPE8, V-TPP8, KTES, etc.; extended ambient temperature operating range — built-in automatic heating system (option); increased reliability — switching equipment and electronic components of leading world manufacturers; any object-orientation upon Customer's request; commissioning works performance time — 4-6 hours.
