Description

Technical Field

[0002] The excitation regulator (Automatic Voltage Regulator, AVR) of a generator is a device used to regulate the output voltage of the generator. Its main function is to monitor the output voltage of the generator and automatically adjust the excitation system when the voltage changes to maintain a stable output voltage. This device usually achieves stable voltage control by controlling the excitation current of the generator, ensuring that the generator can provide a stable voltage output when the load changes or other grid conditions change.

Specifically, the patent discloses the technical solution of "the utility model provides a heat dissipation device for the excitation regulator control cabinet of a thermal power plant generator, including a temperature reduction component and a heat dissipation component. The temperature reduction component includes a control cabinet, and the heat dissipation component includes a mounting ring, a heat dissipation plate, a fixing plate, a rotating shaft, a connecting plate, a brush, a mounting plate, a second motor, a connecting shaft, a driving bevel gear, and a driven bevel gear; a mounting ring is welded to one side of the control cabinet, and a heat dissipation plate is installed on the inner side wall of the mounting ring", and realizes the technical effect of "when the output shaft of the second motor rotates, it can drive the connecting shaft to rotate. When the connecting shaft rotates, it can drive the driving bevel gear to rotate, and then can drive the driven bevel gear and the rotating shaft to rotate, so as to drive the connecting plate and the brush to rotate. When the brush rotates, it can sweep across the surface of the heat dissipation plate to clean the dust on the surface of the heat dissipation plate, preventing dust accumulation from blocking the heat dissipation plate and causing poor air circulation in the control cabinet, and ensuring the heat dissipation effect of the control cabinet".
