GAS DISTRIBUTING STATION WITH POWER INSTALLATION Russian patent published in 2009 - IPC F17D1/04 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to gas industry, particularly to gas reducing equipment with implementation of gas expansion generating technology. The gas distributing station with the power installation consists of a gas heater and boxes with technological blocks connected between them by means of binding; the technological blocks are a switching block and a reducing block; both containing units of pulse gas preparation including filters- dryers and locking elements, a cleaning block with filters and a condensate collector, a block of gas consumption measuring, an odorisation block, a block of control equipment and automation. A gas expanding and generating assembly is installed in the reducing block; it contains a case inside of which the generator is installed and in the case of the generator there are installed: a stator, a rotor on a shaft, a power rectifier connected to a stator, a voltage regulator connected with a power rectifier, sleeves of gas input and output, a turbine in form of an impeller with blades installed on the rotor shaft, a nozzle facility in form of three nozzles arranged in sleeves supplying gas and arranged at the angle of 8°-30° to the surface of impeller blades, an output to the exterior electrical circuit connected to the generator by means of an element from a conductor of a conic shape placed into a connector, between the latter and the conductor there is a dielectric filler. Also the element with the conductor is designed to be screwed off a boss rigidly secured to the case of gas expanding generating facility, the output of which to the exterior electrical circuit is connected with an accumulator battery in its turn connected to a source of no-brake power supply and to a circulation pump of the gas distributing station.

EFFECT: increased reliability of gas distributing station operating.
