High temperature rotor water cycle cooling device

Abstract

The invention discloses a high temperature rotor water cycle cooling device which is used for cooling an excitation rotor. The device comprises a stator and a rotor, the rotor comprises a rotor body, an extending section is arranged at one end of the rotor body, a water storage cavity is arranged on the extending section, a water pipe penetrates through the water storage cavity of the extending section from the position of a central axis line outside the stator and extends into the rotor body, a water inlet is arranged on the water pipe which is arranged on the outer side portion of the stator, a recycled water channel which is communicated with the water storage cavity and the water pipe is arranged in the rotor body, a water outlet hole of the water storage cavity is arranged on the side wall of the extending section, and a water outlet channel which is capable of discharging water in the water storage cavity to the outside of the stator is arranged at the position corresponding to the water outlet hole. By means of the structure, heat generated by high speed rotation of the rotor can be taken away through cooling water in the recycled water channel, the rotor is excellently cooled, the long-term usage of the rotor is facilitated, particularly the phenomenon of power failure in generating devices caused by the fact that the rotor is damaged by high temperature is prevented, and remarkable convenience is brought for users.

Description

technical field [0001] The invention relates to a high-temperature rotor water circulation cooling device for cooling an excitation rotor. Background technique [0002] In existing generators or other equipment that work on the principle of electromagnetic induction, the high-speed rotation of the rotor will cause the temperature of the rotor parts to be very high, and the rotor will be easily damaged in a high-temperature working environment, which is not conducive to the long-term use of the equipment, especially Once the rotor is damaged in wind power generation equipment, it will affect the normal operation of the entire power generation system and bring great inconvenience to people. However, reducing the temperature rise of the rotor has been an insurmountable problem for a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-temperature rotor water circulation cooling device that can effective...
