FIELD: physics.
SUBSTANCE: invention relates to method of high-temperature fluid medium leak detection in turbomachine (10). Turbomachine (10) comprises high-temperature compressed fluid source, at least one fluid distribution line (14, 15) suitable for distribution of said high-temperature fluid medium, and a turbomachine compartment, in which distribution line (14, 15) is at least partially located. Method comprises the following steps, at which: measuring at least two pressure parameters in turbomachine compartment, including measured pressure and pressure change over time; leakage of high-temperature fluid medium is detected when at least one of two pressure parameters in turbomachine compartment reaches the value characteristic for leakage of high-temperature fluid medium in compartment. Invention also relates to high-temperature fluid medium distribution system and to turbomachine containing such high-temperature fluid medium distribution system.
EFFECT: disclosed is a method of detecting leakage of fluid medium in a turbomachine and a fluid distribution system.
