Generator Hydrogen Cooling System Youtube Synchronous generator, power generation ,طرق تبريد المولدات الكهربائية باستخدام الهيدروجين. In the hydrogen cooling of a synchronous generator, hydrogen gas is used for cooling because hydrogen gas has excellent cooling properties. the power loss (i 2 r loss) in the form of heat loss occurs in a generator when the generator delivers power to electrical equipment. the life of the generator depends on how efficient the cooling system it. As generators have grown in size and capacity through the years so has the need to improve efficiency through minimizing heat. hydrogen was first proposed as a cooling media for rotating electrical machinery in 1925. the first hydrogen cooled machine, a 12.5 mva synchronous condenser, was placed into service in 1928. The hydrogen cooling system is uneconomical for such applications. direct water cooling is used for the synchronous generator rating 500 mw and above. in very large turbo generators, hydrogen cooling is used for the cooling of the rotor and the stator winding is cooled with direct demineralized water. the centrifugal pump circulates the water.

Limitations of hydrogen cooling. the frame of the hydrogen cooled alternator is more costly because of the necessity to provide explosion proof construction and gas tight shaft seals. means are necessary to admit hydrogen to the alternator without creating an explosion. sourcing the air with co 2 and then admitting hydrogen. In a hydrogen cooled system, hydrogen gas is used as a medium for cooling. a detailed explanation is given in the article hydrogen cooling of synchronous generator. direct water cooling in synchronous generator. as hydrogen cooling is not sufficient to extract heat generated in large turbo alternators of sizes 500 mw or more.
