1. Funtarwarar Kontrollon Tashin Jikin Turbin

A yau, an fi siffar da turubin tashin jiki zuwa biyu: na kuli mai hula da na kuli mai ba. An yi amfani da na kuli mai ba a cikin gagarun shirya, ofishin sauri, hadadin sama, zabe, wurare masu nuna, da kuma wurare masu nuna mai zurfi saboda dalilai mara - kamar tsaro, babban haɗa, ba ta dogara, ba ta da ake iya, yawan lafiya, tsawo, da kuma adadin ranar.

Wannan daga cewa mafi kyau na na kuli mai ba shine adadin ranar, yawanci ya kamata da shekaru 20. Idan an yi aiki da rike, ya kamata lafiyar da ita. A halayen rayuwa, lafiyar da tsaro na na kuli mai ba yana da muhimmanci sosai. Daga cewa abin da take da gari, yawanci ne mai da ake samu karfin da ake iya. Babu da mutane da ke faruwa wajen gari, abin da ya kamata da ake samu karfin da ake iya.

Duk da haka, adadin ranar na na kuli mai ba yana da muhimmanci saboda "tsawon ranar." Don in fadada adadin ranar, yana da kyau in tabbatar da tashin jikin gari da ake amfani da funtakar kontrollon tashin jiki, kuma in yi takamawa da karfin da ake iya - kamar tashin jikin gari ko takamawa - idan an bukata.

Musamman da yadda adadin Pt100 na zama kadan da harkar jikin ya shaida, ba ake da yawan tsari ba. Don samun inganci, mafi girma da take magana don girmen jiki sun yi koyarren wani karamin darasi daga 0–200°C na kurba da Pt100. A cikin har karamin, ana amfani da rasshen karamin bayanin kamar yadda adadin da yadda harkar jiki ta shaida, wanda yake taimaka wajen yauwa masu karfi ga ci gaban adadin.

3.3 PTC Thermistor as an Alternative Sensor in TTC-300 Series Controllers

PTC (Positive Temperature Coefficient) thermistor shine wani matsayin jiki da ake amfani da ita a cikin IEE-Business TTC-300 series transformer temperature controllers. Ana yi PTC thermistors daga abubuwan barium titanate-based polycrystalline ceramic materials, kuma ana sanya su don tabbatar da "trip" ko "switching" temperatures masu musamman.

Babu da platinum resistors (Pt100), PTC thermistors sun fi yawan tsari mai ba da yawan tsari: adadin su yana da yawan tsari a lokacin da harkar jiki na biyu, amma a lokacin da harkar jiki ya kai nasarorin rahoton, adadin su ya faru da yawan tsari mai sauƙi, yawanci yana da yawan tsari mai sauƙi—wanda ake kira Curie point ko action temperature. Wannan yadda ake nuna ne a cikin adadin–harkar jiki na gaba.

Kamar yadda aka nuna, a cikin harkar jiki na biyu, adadin PTC ba sa shaida da yawa ba. Amma, idan harkar jiki ya kai da kuma ya kai wannan nasaroton rahoton, adadin su ya faru da yawan tsari mai sauƙi—kafin yana da yawan tsari mai sauƙi.

Mafi girma da take magana don girmen jiki na PTC shine don nufin wannan yawan tsarin adadin mai sauƙi don tabbatar da ma ce ake kai wani nasaroton harkar jiki. Saboda haka, PTC sensors ba su iya bayyana adadin jiki na karshe, ba su iya bayyana adadin jiki na karshe kamar Pt100 ba.

Anan amfani da wannan yadda adadin PTC suke faru da yawan tsari mai sauƙi a kan IEE-Business products don girmen over-temperature alarms da kuma trip protection don transformers. Don samun gaskiya, inganci, da kuma kayan aikin, anan amfani da PTC components daga Siemens–Matsushita Electronic Components Co., Ltd.

3.4 TC Temperature Sensing Principle

Mafi girma da take magana don girmen jiki ta shaida da bayanan PTC da Pt100 sensors tun daga cikin takardun girmen jiki, kuma ana amfani da logical judgment don tabbatar da ma ce ake kai over-temperature alarm ko over-temperature trip signal. Wannan dual-protection mechanism yana taimaka wajen kara faɗa da kuma kara gabatarwa.

Ana maye jiki na transformer windings (Phases A, B, C) da core (D) da amfani da Pt100 da PTC sensors. Idan harkar jiki ya shaida, adadin wasu sensors na iya shaida. Mafi girma da take magana don girmen jiki ta shaida da bayanan adadin da ke faru da yawan tsari, kuma ana tashar wannan adadin zuwa voltage signal, kuma ana tashar wannan voltage signal zuwa filtering, analog-to-digital (A/D) conversion, da kuma advanced algorithms don tabbatar da yadda adadin da yadda harkar jiki.

Ta hanyar waɗannan abubuwa na adadin:

• Mafi girma da take magana don girmen jiki ta shaida bayanayan channel number da kuma real-time temperature value a kan front-panel screen.

• Amma, ana amfani da logical algorithms don tabbatar da yadda adadin da aka gano da user-defined setpoints. Idan harkar jiki ya kai nasaroton rahoton, mafi girma da take magana don girmen jiki ta shaida ya faru da outputs masu musamman—kamar starting/stopping cooling fans, triggering alarms, ko initiating a trip command.

Mutane suka zaɓe system parameters—kamar fan start/stop temperatures, core overheat alarm thresholds, da kuma abubuwa—tun daga front-panel buttons.

Amma, anan amfani da system continuous self-diagnostics. Idan anan nufin faɗa na sensor ko internal hardware fault a kan mafi girma da take magana don girmen jiki, anan ya faru da audible and visual alarms da kuma fault signal don tabbatar da operators.
