PLANT OF ANTI-EMERGENCY POWER SUPPLY OF GAS PUMPING UNIT Russian patent published in 2013 - IPC H02J9/06 

FIELD: electricity.

SUBSTANCE: result is achieved due to identification of a separate anti-emergency unattended accumulator battery for anti-emergency power supply of a subgroup of collectors of an aggregate system to control accident-free stop of a gas pumping unit, identified from the set of collectors of the first category of the special group of power supply reliability, in order to avoid uncontrolled emergency stop. At the same time the anti-emergency accumulator battery is automatically connected for power supply to the dedicated subgroup of collectors of aggregate automatics only in case of an incident with disappearance of all three independent mutually redundant sources of supply, providing for power supply to aggregate collectors of the first category of the special group of power supply reliability.

EFFECT: higher safety of a gas pumping unit in part of prevention of such fires and explosions, which may be caused by a non-controlled emergency stop of a fully de-energised device.
