Abstract
The utility model discloses an AC exciter, and specifically relates to an AC exciter for a vertical hydrogenerator. The AC exciter comprises a stator, a rotor, a rectification disc and a fan device, wherein the rotor of the AC exciter is arranged on a main shaft of the hydrogenerator directly; and the rotor of the AC exciter and the main shaft of the hydrogenerator employ a flat key to transmit torque. In this way/Accordingly, the AC exciter is connected with the vertical hydrogenerator, and the AC exciter is simple in structure, convenient to operate and maintain, and reliable in operation.
Description
Technical field
The utility model discloses a kind of AC exciter, relate to a kind of AC exciter of vertical hydrogenerator.
Background technology
At present, the brushless excitation vertical hydrogenerator is widely used in the water power industry.Wherein, AC exciter is the main part of brushless excitation vertical hydrogenerator.Traditional AC exciter has independently bearing arrangement, adopts shaft coupling to transmit moment of torsion, and the shortcoming of this structure is: size is bigger, and complexity is installed, and consumptive material is many, the cost height.
The utility model content
The purpose of this utility model is the shortcoming that overcomes traditional AC exciter, and a kind of AC exciter of new vertical hydrogenerator is provided.
The technical solution of the utility model is as follows:
A kind of AC exciter, it comprises stator, rotor, rectifying disc and fan assembly, it is characterized in that, and the rotor of described AC exciter directly is loaded on generator shaft, and the rotor of described AC exciter and generator shaft adopt flat key to transmit moment of torsion.
Described fan assembly adopts centrifugal fan.
Described flat key adopts 45 steels to do.
The utility model has following advantage compared with prior art:
1. syndeton is simple, installation, convenient disassembly.
2. cost is low, reduces bearing arrangement and coupler structure.
3. reliable.
Description of drawings
Fig. 1 is that master of the present utility model looks cutaway view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Among Fig. 1, the utility model is made up of stator 1, rotor 2, rectifying disc 3, flat key 4 and fan assembly 5.
In conjunction with Fig. 1, the utility model utilizes the rotating operation of generator shaft 6, transmission moment of torsion by flat key 4, allow rotor 2 and fan assembly 5 rotate, rotor 2 cutting stators 1 magnetic field, thereby the function of its generating of realization AC exciter, the alternating current that sends is through rectifying disc 3 rectifications, become direct current, then with cable 7 input generators 8; Fan assembly 5 rotates with rotor 2, and the torrid zone that stator 1 and rotor 2 are produced goes out.Because the rotor 2 of AC exciter directly is loaded on generator shaft 6, rotor 2 and generator shaft 6 adopt flat key 4 to transmit moment of torsion, the coupler structure between the machine is encouraged in the bearing arrangement of cancellation conventional AC exciter self and generator 8 and friendship, makes structure simpler, and cost is low.Simultaneously, an end of cable 7 connects generator 8, and the other end connects rectifying disc 3, and installation and maintenance are more convenient.
Claims (3)
1. AC exciter, it comprises stator, rotor, rectifying disc and fan assembly, it is characterized in that, and the rotor of described AC exciter directly is loaded on generator shaft, and the rotor of described AC exciter and generator shaft adopt flat key to transmit moment of torsion.
2. a kind of AC exciter according to claim 1 is characterized in that, described fan assembly adopts centrifugal fan.
3. a kind of AC exciter according to claim 1 is characterized in that, described flat key adopts 45 steels to do.
