Background
The air expansion turbine generator is a generator driven by an air turbine expander. The compressed and stored air enters the turbine to do work through expansion, so that the turbine blades rotate to drive the generator to generate electricity.
When the generator is in operation, the loss of copper and iron is converted into heat energy, so that all parts of the generator generate heat. In order to ensure that the winding insulation of the generator can operate at the allowable temperature for a long time, the heat generated by the copper and iron losses must be removed, and therefore, the generator must be continuously cooled. The cooling effect of the generator has great influence on the capacity of the generator.
The generator below 50wm is mostly cooled by air, the air cooling has two modes, namely open air cooling and closed air cooling, the open air cooling adopts an auxiliary equipment cooling fan, a motor drives a centrifugal fan through a belt, air is filtered by an air inlet chamber at the lower part of the motor and then is blown into a generator cooling cover through an air channel, and after passing through the axial direction of a rotor and a stator air gap, heat is taken away and is discharged by a lower air channel. The air-conditioning system has the advantages of simple mode, easy maintenance and large occupied space, needs to arrange a working layer below the motor for arranging an air inlet filtering and purifying chamber, a preheating air mixing chamber and a long-distance air supply duct in winter, and has large civil engineering quantity and large working noise. The specific flow is shown in FIG. 4.
The closed ventilation adopts a coaxial fan of a generator, so that wind circulates in the motor in a closed manner, heat exchange is carried out through an air cooler, and heat of the air is transferred to circulating water to bring out heat. The motor has the advantages that the volume of the motor can be effectively controlled, and an air duct layer below the motor is not needed; the disadvantages are high cost and need of auxiliary facilities: water purification system, circulating pump, water storage tank, air cooling tower. Wherein the water purification system is used for water treatment, and impurities in the water are placed to damage the heat exchanger in circulation; the circulating pump is used for cooling water circulation; the water storage tank is used for storing cooling water; the air cooling tower is used for cooling water. The auxiliary system is complex to maintain later and has a large amount of water resource consumption. The specific flow is shown in FIG. 5.
