Abstract

The invention discloses a generator motor temperature control device and a generator motor temperature control method. The generator motor temperature control device comprises a heat-conducting coppertube with one end extending into a motor housing, the housing which is connected with the other end of the heat-conducting copper tube and has an open upper end, a C-shaped elastic metal tube arranged in the housing, a straight tube which is rotatably connected with the free end of the C-shaped elastic metal tube, a transverse rod arranged on the housing and connected with the straight tube, a first gear arranged at the left end of the transverse rod, a second gear meshed with the first gear, a pointer arranged on a rotating shaft of the second gear, and a paintbrush arranged on the pointer,wherein the heat-conducting copper tube is connected with the left portion of the C-shaped elastic metal tube; and the generator motor temperature control device further comprises a driving roller anda driven roller. The generator motor temperature control device has the advantages of being capable of precisely recording the temperature variation in the motor housing, providing reliable data support for the structural improvement of the motor, capable of cooling the motor housing in time, and effectively protecting power generation assemblies in the motor housing.

Description

technical field [0001] The invention relates to the technical field of generator motors, in particular to a temperature control device and method for generator motors. Background technique [0002] Generating motors are mainly used in pumped storage power plants. Since the reversible pump-turbine operates in the opposite direction of rotation as a water turbine and a water pump, the generator motor also needs to run in both directions accordingly. In order to realize the bidirectional operation of the synchronous motor, the phase sequence of the power supply can be converted in the selection of the electrical main wiring and switchgear. [0003] Pumped-storage power stations play the role of valley filling and peak regulation in the power system, requiring frequent start and stop, as well as frequent frequency modulation and phase modulation operations, and frequent adjustment of working conditions. The generator motor is under frequently changing operating conditions, and...
