Kufanana ntchito tiransifoma - zokwaniritsa

Mphamvu - kalekale mbali ya chitukuko. Popanda kulingalira moyo zosatheka. N'chifukwa chake funso kupitiriza kwa magetsi ogula ndi kukhala kunadetsa pachimake. Ntchito yomweyi tiransifoma - imodzi mwa njira zimenezi. Komabe, ngati okha kubwerera ntchito njira, ndi zimene amafuna kwa zida?

N'chifukwa chiyani sitiyenera ntchito yomweyi tiransifoma?

Monga tanena ntchito poyamba anavomera zachititsidwa amafuna kusintha kudalirika kwa magetsi. Komabe, pali ena, n'kofunika, makamaka pamene ntchito yomweyi tiransifoma chofunika. mfundo zimenezi ndi izi:

• mofulumira kuwonjezeka katundu, amene posachedwapa adzakhala upambana (kapena kuposa) a ntchito mphamvu thiransifoma;
• kuchepa kwa malo (kutalika, m'lifupi) sangakwanitse kukhazikitsa lalikulu thiransifoma imodzi, koma inu mukhoza kuika tiwiri ndipo monga iwo mu kufanana;
• Mwachibadwa, kukhwimitsa chitetezo mbali yofunika, monga Mwina kulephera mwakamodzi tiransifoma onse ndi otsika, koma izo ziri, chotero kuwonjezera pa chochitika, ntchito yomweyi tiransifoma, ntchito njira zina kubwerera.

Kuika ntchito ya tiransifoma awiri

Kutembenuza tiransifoma ntchito yomweyi imapereka redundancy amalandira yofunika kwambiri pa mphamvu ya magetsi, zomwe zikusonyeza mosadodometsedwa mphamvu okwanira. Pa ambiri substations ntchito, tiransifoma ziwiri kapena zambiri (kuchotserapo ndi woonda kufala mtundu substation). Ntchito mu kufanana amaloledwa, ngati onse a thiransifoma chili ndi zina za zimene, ndipo amatchedwa "zinthu ntchito yomweyi tiransifoma":

• gulu la windings akhale ofanana ndi mnzake;
• kusinthika magawanidwe kukhala wofanana ndi mzake, kukhala insubstantial kupatuka mkati chovomerezeka malire yovomerezeka;
• voteji madera lalifupi ayenera kukhala wolingana ndi mzake, ndi insubstantial kupatuka mkati chovomerezeka malire yovomerezeka;
• kufanana tiransifoma zifunika kuti zoyendetsedwa kwa maukonde limodzi;
• zingwe sekondale wofunikila kulumikiza thiransifoma kufika ayenera kukhala ndi makhalidwe pafupifupi wofanana ndi kutalika;
• gawo kosangalatsa pakati pa voltages wa windings pulayimale ndi sekondale ayenera kukhala yemweyo.

Kufunika mawerengedwe kuyambirira

Mu nkhani ya kuwonongeka kwa mmodzi wa tiransifoma awiri Sizotheka kusankha chimodzimodzi, zomwe kwathunthu chikufanana ndi zinthu zowonongeka ndi modes opaleshoni. Mu milandu, kusankha ndi thiransifoma chinakhazikika pa kuwerengetsera zovuta kuyambirira kuti zimasonyeza kuti windings wa thiransifoma adzakhala yodzaza wogawana, ndipo palibe mmodzi wa iwo ati kutsegula kuposa mphamvu iliyonse thiransifoma payekha.

Short-dera voteji

Ntchito yomweyi tiransifoma kupezeka pa mfundo ndi wofanana voteji madera lalifupi mu windings wa. Ngati mfundo zosiyanasiyana RS, pamaso kusintha kwa ntchito olowa m'pofunika kale kusintha kusintha chiŵerengero wa tiransifoma ndi lophimba wapadera. Choncho n'zotheka kukwaniritsa chipukuta misozi cha mavuto adagawanso amene uka chifukwa kusiyana dera lalifupi voltages. Akuwuka chifukwa chotero mismatch zokwanira mafunde sadzakhala zimamuchulukira ndi thiransifoma ndi apansi vuto voteji.

Kumene, muyenera kuganizira mphamvu katundu - kaya payekhapayekha aliyense chipangizo chamagetsi, ndi pa zochitika monga ntchito yomweyi tiransifoma mphamvu. Pa chabe, Koma kusiyana ndi alibiretu mphamvu pa mfundo za yochepa dera voteji, chifukwa magawanidwe kusintha ali equalized ndi kukhala zofanana. Pansi pa katundu, ndi voteji sekondale adzakhala osiyana, chifukwa wosiyana voteji dontho zikhoza kutayikira akulipira mafunde chifukwa windings, ndi thiransifoma wina akulipira masiku ano mwachidule ndi maziko, ndipo chachiwiri subtracted. Analimbikitsa chiŵerengero cha mphamvu yamphamvu kwambiri otsika kwambiri mphamvu thiransifoma ayenera kukhala osapitirira atatu wani.

zinthu zilipo

Kufanana ntchito tiransifoma, atatu kumulowetsa awiri, kumulowetsa pa windings onse. Tiyenera kukumbukira kuti zipangizo zogwiritsidwa mu kufanana, katundu ndi anagawira mogwirizana osiyanitsidwa ndi yochepa dera voteji ndi mwachindunji njila kwa mphamvu iliyonse thiransifoma payekha. Ntchito yomweyi tiransifoma, ngati kumulowetsa magulu kugwirizana ndi osiyana, n'zotheka pa magulu onse wosamvetseka. Ngati kulolerana ndi si mgwirizano, ndiye chifukwa chosinthira ngodya pakati pa malo a windings yachiwiri pali voteji kamene kamayambitsa ndi osayenera uyenderere panopa.
