Choyamba, ndi zinthu ziti zomwe zimayenera kugwiritsidwa ntchito limodzi ndi ma seti a jenereta?
Njira yonse yoyika jenereta kuti igwire ntchito yofanana imatchedwa ntchito yofanana. Gulu loyamba la jenereta lidzathamanga, magetsi amatumizidwa ku basi, ndipo jenereta ina imayikidwa pambuyo poyambira, ndipo jenereta yapitayi iyenera kukhala panthawi yotseka, jenereta ya jenereta sayenera kuwoneka yovulaza panopa, shaft si. kukhudzidwa mwadzidzidzi. Pambuyo potseka, rotor iyenera kukokedwa mwamsanga kuti igwirizane. (ndiko kuti, liwiro la rotor ndi lofanana ndi liwiro lovotera) Chifukwa chake, jenereta ya seti iyenera kukwaniritsa izi:
1. Mtengo wogwira ntchito ndi mawonekedwe a mawonekedwe a magetsi a jenereta ayenera kukhala ofanana.
2. Gawo lamagetsi la ma jenereta awiri ndilofanana.
3. Mafupipafupi a seti awiri a jenereta ndi ofanana.
4. Gawo la magawo awiri a jenereta limagwirizana.

Chachiwiri, kodi njira ya quasi-synchronous juxtaposition yama seti a jenereta ndi iti? Momwe mungapangire majuxtapositions munthawi yomweyo?
Quasi-synchronous ndi nthawi yeniyeni. Ndi njira ya quasi-synchronous yogwirira ntchito limodzi, mphamvu yamagetsi ya jenereta iyenera kukhala yofanana, ma frequency ndi ofanana ndipo gawolo limakhala lokhazikika, lomwe limatha kuyang'aniridwa ndi ma voltmeter awiri, ma frequency metres awiri ndi ma synchronous and non-synchronous indicators synchronous disk, ndi masitepe ogwiritsira ntchito ofanana ndi awa:
Kusintha kwa katundu wa jenereta imodzi kumatsekedwa, ndipo magetsi amatumizidwa ku bar, pamene gawo lina liri mu standby state.
Tsekani chiyambi cha nthawi yomweyi, sinthani liwiro la jenereta yoyimilira, kuti ikhale yofanana kapena pafupi ndi liwiro la synchronous (kusiyana kwafupipafupi ndi gawo lina mkati mwa theka la kuzungulira), sinthani voteji ya jenereta yoyimilira, kotero kuti ili pafupi ndi magetsi a magetsi ena a jenereta, pamene mafupipafupi ndi voteji ali ofanana, kuthamanga kwa tebulo la synchronous kumakhala pang'onopang'ono komanso pang'onopang'ono, ndipo kuwala kowonetserako kumakhala kowala komanso mdima nthawi yomweyo; Pamene gawo la gawo loti liphatikizidwe liri lofanana ndi la gawo lina, cholozera cha mita ya synchronous chikuwonetsa malo okwera apakati apakati, ndipo nyali yolumikizana ndi mdima. Pamene kusiyana kwa gawo pakati pa chigawocho kuti chiphatikizidwe ndi gawo lina ndi lalikulu, mita ya synchronous imaloza kumalo apakati omwe ali pansipa, ndipo nyali ya synchronous imayatsidwa panthawiyi. Pamene synchronous mita pointer imayenda mozungulira, zikuwonetsa kuti ma frequency a synchronous generator ndi apamwamba kuposa a unit ena. Liwiro la seti ya jenereta yoyimilira liyenera kuchepetsedwa, ndipo liwiro la seti ya jenereta yoyimilira liyenera kuwonjezeka pamene cholozera cha wotchi chikuzunguliridwa motsata wotchi. Pamene cholozera cha wotchi chimayenda pang'onopang'ono munjira yowongoka ndipo cholozeracho chikuyandikira malo omwewo, chowotcha chamagetsi kuti chiphatikizidwe chimatsekedwa nthawi yomweyo, kuti ma seti awiri a jenereta agwirizane. Masiwichi a mbali ndi mbali osinthira ma chronograph ndi ma chronoswitches ogwirizana nawo.

Chachitatu, ndi chiyani chomwe chiyenera kutsatiridwa pochita quasi-synchronous juxtaposition ya seti ya jenereta?
Kufanana kwa Quasi-synchronous ndi ntchito yamanja, kaya ntchitoyo ndi yosalala komanso zochitika za wogwiritsa ntchito zimakhala ndi chiyanjano chachikulu, pofuna kupewa kufanana kofananako, milandu itatu yotsatirayi siloledwa kutseka.
1. Pamene cholozera cha tebulo la synchronous chikuwoneka chodumphira chodabwitsa, sichiloledwa kutseka, chifukwa pakhoza kukhala chochitika cha makaseti mkati mwa tebulo la synchronous, lomwe silimasonyeza mikhalidwe yoyenera ya juxtaposition.
2. Pamene tebulo la synchronous likuzungulira mofulumira kwambiri, limasonyeza kuti kusiyana kwafupipafupi pakati pa jenereta ya jenereta ndi seti ina ya jenereta ndi yaikulu kwambiri, chifukwa nthawi yotseka yodutsa dera imakhala yovuta kudziwa, nthawi zambiri wophwanya dera satsekedwa pa. nthawi yomweyo, kotero sikuloledwa kutseka nthawi ino.
3. Ngati cholozera cha wotchi chikuyima nthawi yomweyo, sichiloledwa kutseka. Izi zili choncho chifukwa ngati mafupipafupi a imodzi mwa jenereta amasintha mwadzidzidzi panthawi yotseka, n'zotheka kuti wodutsa dera atseke pafupi ndi malo osagwirizana.

Chachinayi, momwe mungasinthire zochitika zam'mbuyo zamayunitsi ofanana?
Pamene magulu awiri a jenereta ali opanda ntchito, padzakhala kusiyana kwafupipafupi ndi kusiyana kwa magetsi pakati pa magulu awiriwa. Ndipo pa chida chowunikira cha mayunitsi awiriwa (ammeter, mita yamagetsi, mita yamagetsi), mphamvu yeniyeni yosinthira ikuwonetsedwa, imodzi ndi mphamvu yosinthira yomwe imayamba chifukwa cha liwiro losagwirizana (ma frequency), inayo ndi mphamvu yosiyana chifukwa cha kusagwirizana. voltage, zomwe zimasinthidwa motere:
