Vifaa vya kusisimua vya jenereta mtandaoni vya ufuatiliaji wa halijoto ya kihisi joto cha nyuzinyuzi ya mwanga ya mwanga ya fluorescence

Generator excitation equipment is prone to heating faults due to high voltage and high current equipment. Wakati wa operesheni, AC demagnetization switches, DC demagnetization switches, or three-phase rectifier power cabinets often burn out; Various faults such as smoke from the demagnetization resistor, ignition of the carbon brush on the generator rotor slip ring, ignition of the anode cable (AC cable) and DC cable (to the generator rotor cable) can cause excitation accidents. The reasons for these accidents are mostly due to the failure to detect potential hazards in the operation of excitation equipment in a timely manner. One of the key variables for the normal operation of excitation equipment is temperature. Njia ya jadi ya kipimo cha joto kawaida hupima joto la vifaa vya kusisimua kwa wakati maalum wakati wa ukaguzi, ambayo haiwezi kufikia ufuatiliaji wa wakati halisi, na baadhi ya sehemu haziwezi kufuatiliwa. Monitoring again after the equipment is shut down is meaningless. Au kipimo cha halijoto cha wakati halisi pekee ndicho kimetumika kwa sehemu binafsi, na kwa sasa hakuna utumiaji wa ufuatiliaji kamili wa halijoto katika wakati halisi na utambuzi wa hitilafu kwa sehemu nyingi muhimu za vifaa vya kusisimua..
Kifaa na mbinu ya ufuatiliaji wa halijoto mtandaoni na utambuzi wa hitilafu wa akili wa vifaa vya uchochezi wa jenereta kulingana na sensorer za joto za nyuzi za fluorescent. Kifaa kinaweza kufuatilia data ya halijoto ya sehemu muhimu kama vile saketi kuu, kubadili demagnetization, upinzani wa demagnetization, daraja la kurekebisha, nk. kwa wakati halisi mtandaoni, na inaweza kufuatiliwa ndani na kwa mbali. Inaweza kuchunguza kwa wakati hatari za uendeshaji wa vifaa vya kusisimua, analyze the temperature of key parts of the excitation equipment based on the output current and ambient temperature of the excitation equipment, and determine whether there are hidden dangers in the operation of the excitation equipment, thereby ensuring the stable operation of the power station and power system.

Due to the harsh environment of some temperature measurement sites, such as high temperature, shinikizo la juu, high electromagnetic interference, and even some temperature measurement sites have certain corrosiveness and radioactivity; Or flammable and explosive, not suitable for electronic temperature measuring equipment to work on site. To solve the problem of temperature measurement in harsh environments, many remote temperature measurement devices have been designed, such as remote infrared temperature measurement devices, remote kipimo cha joto cha wireless vifaa, nk. Hata hivyo, these electronic devices all have some key drawbacks, such as infrared temperature measurement equipment being susceptible to spatial light interference, unable to automatically measure in real-time, unable to enter temperature measurement points in narrow spaces, and generating electric sparks. The temperature measurement nodes of wireless temperature measuring devices are susceptible to on-site electromagnetic interference, greatly affecting temperature measurement accuracy, and even unable to measure temperature. Wakati huo huo, they do not have corrosion and radiation resistance capabilities. The mfumo wa kipimo cha joto cha nyuzi za fluorescence independently developed by FJINO can be directly applied to the stator of a generator for fiber optic temperature measurement.
