An embodiment of the invention provides a temperature measuring system and a temperature measuring method of a magnetic pole screw rod connection joint of a hydro-generator. The temperature measuring system comprises gasket type temperature measuring equipment and a data acquisition device, wherein the gasket type temperature measuring equipment is installed at a magnetic pole joint to be measured, and is used for acquiring and storing temperature data of the magnetic pole joint to be measured; and the data acquisition device is used for adopting a wireless communication method for reading all the temperature data acquired by the gasket type temperature measuring equipment. According to the temperature measuring system, since the gasket type temperature measuring equipment can be installed at the magnetic pole joint to be measured, the gasket type temperature measuring equipment is fully contacted with the magnetic pole joint to be measured, thus accurate and reliable temperature data can be acquired, and the precision of the magnetic pole joint temperature measurement is improved; the field monitoring of temperature of the magnetic pole joint by staff during the operation of the generator is avoided, and the convenience and safety of magnetic pole joint temperature measurement are realized; and the arrangement of a large number of data lines on a rotor for transmitting data is avoided, the safe and stable operation of the rotor is ensured, and the safety of magnetic pole joint temperature measurement is further improved.
Description
technical field [0001] The invention relates to the technical field of hydraulic generators, in particular to a temperature measuring system and method for a magnetic pole screw connection joint of a hydraulic generator. Background technique [0002] In recent years, with the increasing installed capacity of hydroelectric generators, the size of generators has also been increasing, especially with the continuous development of the pumped storage industry, high-speed and large-capacity units continue to appear. The following defects are also increasing, among which, the excessive temperature of the rotor magnetic pole joint of the hydro-generator is one of the common defects at present. [0003] The magnetic pole joints of large hydro-generators with high speed and large capacity are generally connected by screws. During the operation of the unit, the magnetic pole joints not only flow a large current (for example, 1-2 thousand amperes), but also receive relatively large stre...
