FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of gas transmission systems, in particular to anti-surge protection systems of turbochargers. Electrically driven gas pumping unit contains the kinematically connected supercharger and the electric actuator, including the high-speed asynchronous motor and the frequency converter with the DC link, block emergency control of the frequency converter associated with the automatic control system, the supply of electricity to the electric drive, supply and discharge pipelines and the recirculation pipeline with the anti-surge valve. Threshold voltage sensor is additionally installed in the DC link of the frequency converter, and the anti-surge valve and the threshold voltage sensor are connected to the automatic control system.
EFFECT: invention is aimed at ensuring uninterrupted operation and improving the reliability of the unit.
