Problems solved by technology

However, when existing hydrogen-cooled generators are replaced by carbon dioxide in the busbar, liquid carbon dioxide releases gas from the cylinder and absorbs a large amount of heat, causing heat exchange valves and busbar pipes to freeze, and the release speed is limited, affecting the safety of the unit. And it prolongs the gas replacement time, which affects the start-up and shutdown time of the unit

Abstract

The invention discloses a carbon dioxide supply device of a hydrogen-cooled generator and a gas replacement system thereof. The carbon dioxide supply device of the hydrogen-cooled generator comprisesan inflation pipeline, a plurality of carbon dioxide gas storage parts, a pressure reducer, a heating part and a temperature detection part, wherein the inflation pipeline is provided with a gas supplementing port and a gas inlet communicated with the hydrogen-cooled generator, the plurality of carbon dioxide gas storage parts are connected in parallel and then are communicated with the gas supplementing port, the pressure reducer is arranged on the inflation pipeline, the heating part is arranged on the inflation pipeline and located between the air supplementing port and the pressure reducer, and the temperature detection part is arranged on the inflation pipeline and is adjacent to the pressure reducer. According to the technical scheme, the carbon dioxide supply device of the hydrogen-cooled generator can effectively reduce freezing of the pipeline and save energy.

Description

technical field [0001] The invention relates to the technical field of hydrogen-cooled generators, in particular to a carbon dioxide supply device for a hydrogen-cooled generator and a gas replacement system thereof. Background technique [0002] At present, when the hydrogen-cooled generator is shut down for maintenance or maintenance, in order to avoid the mixture of air and hydrogen and produce explosive gas, it is necessary to use carbon dioxide as an intermediate isolation gas to replace the hydrogen, so as to prevent the generator from entering oil and prevent the oil-water hydrogen system of the generator The purpose of equipment damage is to reduce the amount of operation of the operating personnel and increase the availability factor of the unit. However, when existing hydrogen-cooled generators are replaced by carbon dioxide in the busbar, liquid carbon dioxide releases gas from the cylinder and absorbs a large amount of heat, causing heat exchange valves and busba...
