Beschreibung
Zusammenfassung:	The invention discloses a vacuum measuring system for the steam condensing device of a steam turbine and a pressure tapping method. The vacuum measuring system comprises a plurality of primary pressure tapping elements which are evenly distributed at the same section of the throat of the steam condensing device; one end of each primary pressure tapping element is connected to a pressure tapping main pipe; two ends of the pressure tapping main pipe are closed; a plurality of pressure tapping branch pipes are connected to the pressure tapping main pipe; each pressure tapping branch pipe is vertically arranged; and each pressure tapping branch pipe is connected with a pressure transmitter/pressure switch. According to the vacuum measuring system for the steam condensing device of the steam turbine of the invention, the primary pressure tapping elements are evenly distributed at the same section of the throat of the steam condensing device; each pressure tapping branch pipe is connected with one pressure transmit
