Problems solved by technology

[0003] 1. The excavation volume of the foundation of the power station is large, and the foundation cost is high
[0004] 2. The wind circulation route passes through the foundation pit, which easily brings the dust and moisture in the pit into the interior of the hydro-generator, polluting the hydro-generator
[0005] 3. It is inconvenient for the staff to install and maintain the air cooler in the narrow foundation pit, and the operation is difficult
[0006] 4. Since the shaft-extension tubular unit needs to flow through the bottom of the hydro-generator, the design of the hydro-generator with the traditional closed circulation ventilation cooling structure cannot be selected.

Abstract

The invention relates to a hydrogenerator, in particular to a shaft extension tubular hydrogenerator. The shaft extension tubular hydrogenerator comprises a rotor, a stator, left and right hoods, an air cooler, a pedestal bearing, a base and an upper hood, wherein the air cooler is placed at the top of the stator; the left and the right hoods are positioned on the two sides of the stator; and the upper hood is positioned at the upper parts of the stator and the left and the right hoods. Air is sealed in an enclosed space formed by the upper hood, the left and the right hoods, the stator and the rotator; and under the rotation action of the fan of the rotor, the circulation line of the air is: the rotor - the stator - the air cooler - the upper hood - the left-right hood - the rotor. According to the shaft extension tubular hydrogenerator, the structure is compact; the cold air is stable and low in temperature and the cooling effect is good due to the adoption of the air cooler for heat exchange; the air is clean, dry and pollution-free; the generator is low in noise; the air cooler is convenient and simple to mount and maintain and not limited by the space; and the workshop foundation is small in excavated volume and low in cost.

Description

technical field [0001] The invention relates to a hydroelectric generator, in particular to a shaft extension tubular hydroelectric generator. Background technique [0002] At present, using air as the cooling medium to cool the stator and rotor windings and the surface of the iron core is the main cooling method for hydro-generators. The air cooler is located at the lower part of the stator in the traditional closed circulation ventilation cooling structure of the hydroelectric generator. The rotor, stator, left and right windshields, air cooler, downpipe and foundation pit together form a closed circulation space. The air circulation route is: rotor → stator → downwind pipe → air cooler → foundation pit → left and right wind Cover → rotor. The disadvantages of this structure are as follows: [0003] 1. The excavation volume of the foundation of the power station is large, and the foundation cost is high. [0004] 2. The wind circulation route passes through the foundat...
