Beschreibung
Zusammenfassung:	A unit air seal air supply system for cold start of a steam turbine comprises an adjacent machine auxiliary steam header, a first port of the adjacent machine auxiliary steam header is connected with an adjacent machine air supply pipeline, and a second port of the adjacent machine auxiliary steam header is connected with a first port of an auxiliary steam standby header through a connecting pipeline. A second port of the auxiliary steam standby header is connected with a three-section steam extraction port of the medium-pressure cylinder through a three-section steam extraction pipeline, and a third port of the auxiliary steam standby header is connected with a first inlet of the shaft seal gas supply header through a shaft seal header gas supply pipeline. A first outlet of the shaft seal air supply header is connected with an inlet of the second pressure equalizing box through a low-pressure shaft seal air supply pipeline, the second pressure equalizing box provides shaft seal steam for the low-pressure cyl
