Dongosolo Lolamulira Ntchito Yofanana

Mafotokozedwe Akatundu

Choyamba, kodi zinthu zomwe zimayenera kuchitika kuti jenereta igwire ntchito nthawi imodzi ndi ziti?
Njira yonse yoyika jenereta mu ntchito yofanana imatchedwa ntchito yofanana. Seti yoyamba ya jenereta idzayenda, magetsi amatumizidwa ku basi, ndipo jenereta ina ikayamba, ndipo seti ya jenereta yapitayi, iyenera kukhala mu nthawi yotseka, seti ya jenereta sayenera kuwoneka ngati mphamvu yoipa ya impulse, shaft sidzakhudzidwa mwadzidzidzi. Pambuyo potseka, rotor iyenera kukokedwa mwachangu kuti igwirizane. (ndiko kuti, liwiro la rotor ndi lofanana ndi liwiro loyesedwa) Chifukwa chake, seti ya jenereta iyenera kukwaniritsa izi:
1. Mtengo wogwira ntchito ndi mawonekedwe a mafunde a magetsi a jenereta ziyenera kukhala zofanana.
2. Gawo la magetsi la majenereta awiriwa ndi lomwelo.
3. Kuchuluka kwa ma seti awiri a jenereta ndi komweko.
4. Mndandanda wa magawo a ma seti awiri a jenereta ndi wofanana.

Chachiwiri, kodi njira yolumikizirana ya quasi-synchronous ya jenereta ndi iti? Kodi mungapange bwanji ma juxtapositions nthawi imodzi?
Quasi-synchronous ndiye nthawi yeniyeni. Ndi njira ya quasi-synchronous yogwirira ntchito motsatizana, magetsi opangidwa ndi jenereta ayenera kukhala ofanana, ma frequency ndi ofanana ndipo gawo limakhala logwirizana, lomwe lingathe kuyang'aniridwa ndi ma voltmeter awiri, ma frequency meters awiri ndi zizindikiro zotsatizana komanso zosatsatizana zomwe zayikidwa pa diski yotsatizana, ndipo njira zotsatizana zogwirira ntchito ndi izi:
Chosinthira cha jenereta imodzi chimatsekedwa, ndipo magetsi amatumizidwa ku basi, pomwe gawo lina lili mu mkhalidwe woyimirira.
Tsekani chiyambi cha nthawi yomweyi, sinthani liwiro la jenereta yoyimirira, kuti ikhale yofanana kapena yoyandikira liwiro logwirizana (kusiyana kwa ma frequency ndi unit ina mkati mwa theka la kuzungulira), sinthani voltage ya seti ya jenereta yoyimirira, kuti ikhale pafupi ndi voltage ya seti ina ya jenereta, pamene ma frequency ndi voltage zili zofanana, liwiro lozungulira la tebulo logwirizana limakhala locheperako komanso locheperako, ndipo kuwala kowonetsa kumakhala kowala komanso kwamdima nthawi yomweyo; Pamene gawo la unit lomwe liyenera kugwirizanitsidwa ndi lofanana ndi la unit ina, cholozera cha mita yolumikizana chimasonyeza malo apakati a sikweya pamwamba, ndipo nyali yolumikizana ndi yochepa. Pamene kusiyana kwa gawo pakati pa unit yomwe ikuyenera kugwirizanitsidwa ndi unit ina kuli kwakukulu, mita yolumikizana imaloza pamalo apakati pansipa, ndipo nyali yolumikizana imayatsidwa panthawiyi. Pamene cholozera cha mita yolumikizana chizungulira mozungulira wotchi, zimasonyeza kuti ma frequency a jenereta yolumikizana ndi apamwamba kuposa a unit ina. Liwiro la seti ya jenereta yoyimirira liyenera kuchepetsedwa, ndipo liwiro la seti ya jenereta yoyimirira liyenera kuwonjezeredwa pamene cholozera cha wotchi chizunguliridwa mozungulira wotchi. Pamene cholozera cha wotchi chizungulira pang'onopang'ono motsatira njira yowongoka ndipo cholozera chikuyandikira mfundo yomweyo, choswera cha dera la chipangizo chomwe chiyenera kugwirizanitsidwa chimatsekedwa nthawi yomweyo, kotero kuti ma jenereta awiriwa azikhala ofanana. Ma switch a chronograph odulidwa mbali ndi mbali ndi ma chronoswitch ogwirizana nawo.

Chachitatu, kodi ndi chiyani chomwe chiyenera kuganiziridwa pochita kusakanikirana kwa jenereta ndi zinthu zina?
Kufanana kwa quasi-synchronous ndi ntchito yamanja, kaya ntchitoyo ndi yosalala komanso zomwe wogwiritsa ntchitoyo akuchita zili ndi ubale wabwino, kuti apewe kufanana kosiyanasiyana kwa synchronous, milandu itatu yotsatirayi siloledwa kutsekedwa.
1. Pamene cholozera cha tebulo logwirizana chikuwoneka ngati chochitika chodumphadumpha, sichiloledwa kutseka, chifukwa pakhoza kukhala chochitika cha kaseti mkati mwa tebulo logwirizana, chomwe sichikuwonetsa mikhalidwe yolondola yolumikizana.
2. Pamene tebulo logwirizana lizungulira mofulumira kwambiri, zimasonyeza kuti kusiyana kwa ma frequency pakati pa jenereta ndi jenereta ina ndi kwakukulu kwambiri, chifukwa nthawi yotseka ya circuit breaker imakhala yovuta kuyidziwa bwino, nthawi zambiri circuit breaker simatsekedwa nthawi imodzi, kotero siziloledwa kutseka panthawiyi.
3. Ngati cholozera cha wotchi chayima nthawi yomweyo, sichiloledwa kutseka. Izi zili choncho chifukwa ngati kuchuluka kwa jenereta imodzi kumasintha mwadzidzidzi panthawi yotseka, ndizotheka kupangitsa kuti chotsegula mawaya chitseke pamalo osalumikizana.

Chachinayi, momwe mungasinthire mphamvu yosinthira ya mayunitsi ofanana?
Pamene ma jenereta awiriwa sakugwira ntchito, padzakhala kusiyana kwa ma frequency ndi ma voltage pakati pa ma seti awiriwa. Ndipo pa chida chowunikira cha mayunitsi awiriwa (ammeter, power meter, power factor meter), mkhalidwe weniweni wa mphamvu yotsutsana umawonetsedwa, imodzi ndi mphamvu yotsutsana yomwe imayambitsidwa ndi liwiro losasinthasintha (frequency), inayo ndi mphamvu yotsutsana yomwe imayambitsidwa ndi voltage yosagwirizana, yomwe imasinthidwa motere:
