Yadda Kaɗanda Tsakiyar Dukkana

Yadda na gudanar da Turbinin Induction don Gudanar Daidaituwar Rikicin

Yadda na gudanar da turubinai shi ne cikin hanyoyi masu yiwuwa ga gudanar daidaituwar rikicin turbinin induction. Yadda na iya gudanar daidaituwar rikicin tare da bayan turubinai ya kasance kawai da ake amfani da shi a matsayin yadda mai ma'ana ga gudanar daidaituwar rikicin turbinin cage.

An samun hanyoyi uku daga cikinsu wadanda ake iya kawo alamar stator:

• Matsayin alamar stator duk biyu

• Yadda na matsayin alamar consequent

• Pole amplitude modulation (PAM)

Za a bayyana har yadda daga cikin hanyoyin da suka kawo alamar stator a kan baya:

Matsayin Alamar Stator Duk Biyu

A cikin yadda na matsayin alamar stator duk biyu, an yi alamari biyu a kan stator, kafin kada alama ta zama da adadin alamar daban-daban. Ana sanya waɗannan alamar duk fata. Misali, za a iya duba turbinin da ake fitowa da alamar 6 - pole da 4 - pole. Idan ake sanya shi da frequency na tsarin kula da 50 hertz, za suka samun daidaituwar daidaituwar na synchronus 1000 wasu sa minuta da 1500 wasu sa minuta, saboda haka. Amma, wannan yadda na gudanar daidaituwar ta da abubuwan da ba su da kyau, ita ce mafi karfin kula da mafi girman lalace a yi ita musamman daga hanyoyin da ke kusa.

Yadda na Matsayin Alamai Consequent

A cikin yadda na matsayin alamai consequent, ana kawo alamar stator duk biyu zuwa wurare, kafin kada alama ta zama da adadin alamar daban-daban. Tushen waɗannan wurare suna fitowa don damar abubuwa. A cikin yadda ake amfani da shi, ana kawo alamar stator duk biyu zuwa wurare biyu, tare da za a iya kawo alamar da ratio 2:1.

Wannan takarda ta nuna fase na biyu na alamar stator wanda ya haɗe da koilu 4. An kawo waɗannan koilu zuwa wurare biyu, a nan ake kira a - b da c - d.

Wuraren a - b an haɗe da adadin koilu karamin 1 da 3, inda wuraren c - d an haɗe da adadin koilu 2 da 4. Waɗannan koilu biyu a kan wurara suna haɗe da kungiyar series. Kamar yadda aka nuna a takarda, terminal a, b, c, da d suka fitowa don damar abubuwa.

Karamin kula a kan waɗannan koilu zai iya kontrola tare da kungiyar koilu a sanya kungiyar series ko parallel, kamar yadda aka nuna a takarda. Wannan yadda na damar abubuwa zai taimakawa wajen kontrola magnetic field da alamar stator suka haɗe, wanda yana da muhimmanci wajen kawo alamar da kuma gudanar daidaituwar turbinin induction.

A cikin tsarin kula na 50 - hertz, idan alamar stator suka haɗe da adadin alamar 4, za suka samun daidaituwar na synchronus 1500 wasu sa minuta (rpm).

Kamar yadda aka nuna a takarda, idan yanayin kula a kan koilu gruppen a - b ya jagoranci, akwai inganci a kan magnetic field da alamar stator suka haɗe. A kan wannan hali, duka waɗannan koilu a kan alamar zai haɗe da north (N) poles. Wannan inganci a kan alamar zai taimakawa wajen gudanar daidaituwar da manufakturin turbinin, wanda yana da muhimmanci a cikin yadda na gudanar daidaituwar rikicin turbinin induction.

Principles of Pole-Changing and PAM Technique

Don cin kula na magnetic circuit, flux na magnetic na alamar group ya fi shiga space daga alamar groups. Saboda haka, ana haɗe S - pole na opposite polarity. Waɗannan alamar da suka haɗe suka kiran a matsayin alamar consequent. Saboda haka, adadin alamar a kan machine ya zama dubu daga adadin da ke faru (misali, 4 to 8 poles), da kuma daidaituwar na synchronus ya zama nemi (misali, 1500 rpm to 750 rpm).

Wannan principle zai iya amfani a kan hukumar uku na turbinin induction. Ta haka, tare da kudin kungiyar series da parallel connections da kuma kudin star ko delta connections, zai iya samun gudanar daidaituwar, operation na constant torque, constant power, ko variable torque operation.

Pole Amplitude Modulation (PAM) Technique

Pole amplitude modulation yana ba da hanyoyi mai yiwuwa ga kawo alamar. Ba tare da hanyoyin tradishen da suka iya samun ratio na 2:1, PAM zai iya amfani a cikin yankunan da suka bukatar speed ratios daban-daban. Turbinin da ake kirkiro don gudanar daidaituwar da kula ta PAM suna kira PAM motors. Waɗannan turbinin sun ba da flexibility mai yiwuwa a cikin gudanar daidaituwar, tare da zai iya amfani a kan yankunan da suka bukatar gudanar daidaituwar mai yiwuwa da kula.
