N’chifukwa chiyani pakati pa transformer pamafunika kukhazikika?

1.N’chifukwa chiyani pakati pa transformer pamafunika kukhazikika?

Pamene transformer ikugwira ntchito, pakati pa chitsulo, pakati pa chitsulo chokhazikika, ndi kapangidwe ka chitsulo cha kuzunguliza, zigawo, zigawo, ndi zina zotero zonse zimakhala mu gawo lamagetsi lamphamvu. Pansi pa mphamvu ya mphamvu yamagetsi, zimakhala ndi mphamvu yayikulu yapansi. Ngati pakati pa chitsulo sipakhazikika, padzakhala kusiyana pakati pa icho ndi chogwirira chokhazikika ndi thanki yamafuta. Pansi pa mphamvu ya mphamvu, kutulutsa kwadzidzidzi kungachitike.

Kuphatikiza apo, pamene transformer ikugwira ntchito, pamakhala mphamvu yamphamvu ya maginito yozungulira chozungulira. Pakati pa chitsulo, kapangidwe ka chitsulo, zigawo, zigawo, ndi zina zotero zonse zili mu mphamvu ya maginito yosagwirizana. Mtunda pakati pawo ndi chozungulira si wofanana. Chifukwa chake, chilichonse. Kukula kwa mphamvu yamagetsi yoyambitsidwa ndi mphamvu ya maginito ya zomangamanga zachitsulo, zigawo, zigawo, ndi zina zotero sikufanana, ndipo palinso kusiyana komwe kungachitike pakati pa wina ndi mnzake. Ngakhale kusiyana komwe kungachitike si kwakukulu, kumathanso kuswa kusiyana pang'ono kwa insulation, komwe kungayambitsenso kutulutsa kwa micro-discharge kosalekeza.

Kaya ndi kutuluka kwa mpweya kosalekeza komwe kungachitike chifukwa cha kusiyana kwa mphamvu, kapena kutuluka kwa mpweya kosalekeza komwe kumachitika chifukwa cha kusweka kwa malo osungira mpweya pang'ono, sikuloledwa, ndipo n'kovuta kwambiri kuyang'ana magawo a kutuluka kwa mpweya kosalekeza kumeneku.

Yankho lothandiza ndi kupukuta bwino pakati pa chitsulo, pakati pa chitsulo chokhazikika, ndi zitsulo zozungulira, zigawo, zigawo, ndi zina zotero, kuti zikhale pamtunda womwewo monga thanki yamafuta. Pakati pa transformer pali pansi pa malo amodzi, ndipo pakhoza kupukutidwa pa malo amodzi okha. Chifukwa mapepala achitsulo a silicon a pakati pa chitsulo amatetezedwa, izi ndi kuletsa kupanga mafunde akuluakulu a eddy. Chifukwa chake, mapepala onse achitsulo a silicon sayenera kupukutidwa kapena kupukutidwa pa malo angapo. Kupanda kutero, mafunde akuluakulu a eddy adzayambitsidwa. Pakati pawo pamakhala kutentha kwambiri.

Pakati pa chitsulo cha transformer pamakhala pansi, nthawi zambiri chidutswa chilichonse cha chitsulo cha silikoni cha pakati pa chitsulo chimakhala pansi. Ngakhale mapepala achitsulo a silikoni amakhala otetezedwa, mphamvu zawo zotetezera kutentha zimakhala zochepa kwambiri. Mphamvu yamagetsi yosagwirizana komanso mphamvu yamphamvu ya maginito zimatha kupangitsa kuti magetsi amphamvu omwe amapangidwa m'mapepala achitsulo a silikoni ayende kuchokera pansi kupita pansi kudzera m'mapepala achitsulo a silikoni, koma amatha kuletsa mafunde a eddy. Amayenda kuchokera ku chidutswa chimodzi kupita ku china. Chifukwa chake, bola ngati chidutswa chilichonse cha chitsulo cha silikoni cha pakati pa chitsulo chili pansi, ndizofanana ndi kuyika pansi chitsulo chonse.

Tiyenera kudziwa kuti pakati pa chitsulo cha transformer payenera kukhala pansi pa mfundo imodzi, osati pa mfundo ziwiri, komanso kuposa pa mfundo zingapo, chifukwa kukhazikika kwa mfundo zambiri ndi chimodzi mwa zolakwika zomwe zimachitika pa transformer.2. N’chifukwa chiyani pakati pa transformer sipangakhale maziko pa mfundo zingapo?

Chifukwa chomwe ma lamination a transformer core angakhazikitsidwe pamalo amodzi okha ndichakuti ngati pali malo opitilira awiri okhazikitsira, kuzungulira kungapangidwe pakati pa malo okhazikitsira. Pamene njanji yayikulu ikudutsa mu kuzungulira kotsekedwa kumeneku, mphamvu yozungulira idzapangidwa mmenemo, zomwe zimayambitsa ngozi chifukwa cha kutentha kwambiri mkati. Pakati pa chitsulo chosungunukacho chidzapanga vuto la short-circuit pakati pa chitsulo, zomwe zidzawonjezera kutayika kwa chitsulo, zomwe zidzakhudza kwambiri magwiridwe antchito ndi magwiridwe antchito abwinobwino a transformer. Pepala lachitsulo la silicon core lokha ndi lomwe lingasinthidwe kuti likonzedwe. Chifukwa chake, transformer siloledwa kukhazikika pamalo angapo. Pali nthaka imodzi yokha.

3. Kuyika pansi kwa mfundo zambiri ndikosavuta kupanga mphamvu yozungulira komanso kosavuta kupanga kutentha.

Pa nthawi yogwira ntchito ya transformer, zigawo zachitsulo monga chitsulo chapakati ndi ma clamps zonse zimakhala mu mphamvu yamagetsi yamphamvu, chifukwa electrostatic induction imapanga mphamvu yoyandama pa chitsulo chapakati ndi zitsulo, ndipo mphamvu imeneyi idzatuluka pansi, zomwe sizovomerezeka. Chifukwa chake, chitsulo chapakati ndi ma clips ake ziyenera kukhazikika bwino komanso modalirika (kupatula mabotolo apakati okha). Chitsulo chapakati chimaloledwa kukhazikika pamalo amodzi okha. Ngati mfundo ziwiri kapena zingapo zakhazikika, chitsulo chapakati chidzapanga kuzungulira kotsekedwa ndi malo okhazikika ndi nthaka. Transformer ikagwira ntchito, mphamvu ya maginito idzadutsa mu kuzungulira kotsekedwa kumeneku, komwe kudzapanga mphamvu yotchedwa circulating current, zomwe zimapangitsa kuti chitsulo chapakati chizitentha kwambiri, komanso kuyatsa zigawo zachitsulo ndi zigawo zoteteza.

Mwachidule: chitsulo chapakati cha transformer chingakhazikitsidwe pamalo amodzi okha, ndipo sichingakhazikitsidwe pamalo awiri kapena kuposerapo.
