Embodiment Construction
[0010] The present invention is realized in this way, a generator for real-time measurement of rotor winding temperature, which includes generator 1, rotor winding 2, temperature sensor 3, rotating shaft 4, slip ring 5, carbon brush 6, bearing cover 7, box 8; if figure 1 As shown, the outlet hole of the temperature sensor 3 is processed at the rear end of the rotating shaft 4, and a shaft extension for installing the slip ring 5 is added at the rear end of the rotating shaft 4. A temperature sensor 3 is embedded at the bottom of the rotor winding 2 when it is wound. Install the slip ring 5 on the rear end of the rotating shaft 4, then pass the lead wire of the temperature sensor 3 through the rear outlet hole of the rotating shaft 4, and then connect the lead wire of the temperature sensor 3 to the slip ring 5. Process the installation hole for installing the carbon brush 6 on the bearing cover 7, install the carbon brush 6 on the bearing cover 7, and then connect the lead wi...

The invention provides a generator capable of timely measuring the rotor winding temperature, including a generator, a temperature sensor, a rotor winding, a slide ring, a carbon brush, a rotating shaft, a bearing cap and an outlet box. The generator is provided with the temperature sensor, the rotor winding, the slide ring, the carbon brush, the rotating shaft, the bearing cap and the outlet box. The rear end of the rotating shaft is provided with an outlet hole of the temperature sensor. The tail part of the rotating shaft is provided with a shaft extension for installing the slide ring. When the rotor winding is coiling, the bottom part of the rotating shaft is provided with the temperature sensor in a buried manner. The slide ring is installed at the rear end of the rotating shaft. A leading wire of the temperature sensor passes through the outlet hole of the rotating shaft and then jointed to the slide ring. The bearing cap is provided with an installation hole for installing the carbon brush. The leading wire of the carbon brush is jointed to the outlet box. The generator capable of timely measuring the rotor winding temperature is advantaged by simple structure, small size, convenient usage and low cost, and can meet requirements for timely measuring the generator rotor winding temperature.
Description
technical field [0001] The invention relates to a generator, in particular to a generator for real-time measurement of rotor winding temperature. Background technique [0002] In order to ensure the safe and reliable operation of the generator in small and medium-sized synchronous generators, the stator winding temperature and bearing temperature of the generator are usually measured in real time. Because the rotor winding is a rotating body, it is difficult for the temperature sensor to transmit the temperature signal to related instruments and equipment. Generally, the temperature of the rotor winding is not measured in real time. Abnormal conditions such as generator overload, low-speed operation, and inter-turn short circuit of the rotor winding will cause the temperature of the rotor winding to rise. When the temperature rises above the allowable temperature, if there is no real-time measurement of the rotor winding temperature, the temperature signal will be sent to R...
