Chifukwa ikulira thiransifoma: zimayambitsa ndi zotheka Kupha phokoso

Kamodzi mu United States m'zaka za m'ma makumi awiri anali malonda otchuka pa "atumiki chete". Funso nkhawa mphamvu, kapena kani, umatha mwakachetechete kuchita ntchito zosiyanasiyana. General Zamagetsi Company kufuna tcheru anthu ogula zipangizo banja. Koma ngati inu kukhudza ndondomeko yakuthupi kotheratu, magetsi ntchito, likukhalira, si chotero "chete." Chitsanzo ndi thiransifoma odziwika ndi chipangizo amene amatha kutulutsa ndithu phokoso mokweza. Choncho n'chifukwa chiyani ikulira thiransifoma?

Kodi ndi thiransifoma

Kuti timvetse zimenezi, sikusokoneza timakumbukira sukulu phunziro sayansi, limene limafotokoza mfundo ya ntchito thiransifoma lapansi. Thiransifoma akuthamanga pa maziko a lamulo la kupatsidwa ulemu mu atomu. Pamafunikanso koyilo bala waya wa diameters osiyana ndi manambala osiyanasiyana ankasinthana. coils Awa windings pulayimale ndi sekondale ya thiransifoma lapansi. Pakati windings pali kugwirizana. Iwo akuyendera ndi mtundu wa mphete wapadera wa ferromagnetic zitsulo. Mphete ankatchedwa pachimake ndipo lili mkati windings wa. Kamangidwe kwambiri pakati ali pamodzi ndi mbale woonda.

Pamene chachikulu kumulowetsa umaperekedwa alternating masiku ano amapangira maginito mu pakati. Pofunika komanso zimasiyanasiyana malinga ndi kusintha spawned panopa ake. Nawonso munda kupatsidwa ulemu induces electromotive mphamvu mu koyilo sekondale - ndi wotembenuka magetsi.

nkhani pachimake lagawidwa ndi kuchuluka kwa microregions. Aliyense gawo amenewa popanda pamaso pa voteji athandizira alipo munda wake maginito imatsogoleredwa zosiyana zambiri kwa wina ndi mzake. Komabe, mwapanikizika ulusi onse amayamba kuthamangira mbali imodzi, kupanga maginito amphamvu. Zonsezi limodzi ndi kusintha mu miyeso thupi la pakati. Tsopano inu mukhoza kuwona chifukwa ikulira thiransifoma.

magnetostriction

Kuyambira kumunda ndi alternating, pachimake mbale ndi kuyamba kuotcha ndi kutambasula mu nawo. Zimenezi amatchedwa magnetostriction. Yopangidwa magulu amenewa ndi pafupipafupi mkulu 100 Hz pa pafupipafupi panopa 50 Hz, danga abwera kugwedera amene ali mawu gulu ndi distinguishable ndi khutu la munthu. Kuwonjezera pa mlingo muyezo mu zikuchokera kwa AC ali zambiri harmonics mkulu pafupipafupi. Iwo anali kwambiri, m'pamenenso yodzaza thiransifoma, amene nawonso, zambiri lakuthwa ndi lomveka Phokoso. Ndicho chifukwa ikulira thiransifoma.

Zina mwa phokoso mu thiransifoma ndi

Koma si zifukwa za "talkativeness" thiransifoma zobisika magnetostriction lapansi. Chifukwa othodwa thiransifoma ikulira? Zimatulutsa phokoso:

• Thiransifoma windings. Ichi ndi chifukwa kamwazi maginito kuyesera aithamangitse wachibale pachimake kumulowetsa. Phokoso ndi nakweza pa nkhani ya bwino bala koyilo, ngati akutembenukira zoipa pafupi wina ndi mnzake.
• Kore mbale. Chifukwa chiyani? The thiransifoma zambiri mkamwamkamwa m'dziko pamene iwo sizikugwirizana ndi kukhala mipata pakati pa pamalo pomwepo. Kenako, kuwonjezera pa psinjika, phokoso amveka ku zitsulo akulira.

• Chilema kapena kuwonongeka kwa kutchinjiriza a mawaya mkuwa. Izi zikhoza kuchitika mu makulidwe a kumulowetsa, pamene pali kutentha. Pankhaniyi, pakati pa windings akhoza kuzembera kuthetheka, kenako kiliki. kumaliseche ndi wamphamvu kwambiri, khalidwe phokoso ndi mokweza.
• looseness onse mu thiransifoma chake? The thiransifoma ma buzz pa ntchito, monga iwo kulira.

Pofuna kupewa drawback ichi, Transformers, mitundu chete yapangidwa. chiwembu chawo inamangidwa m'njira imene panopa pafupipafupi kutembenuka mtima (kuchuluka) mlingo kumene kugwedera si m'zinthu zosiyanasiyana audio. Izi kHz 10 ndipo pamwamba. Wa bata tiransifoma pa kukula kwake ndi kulemera ndi zochepa wamba.

Pomaliza

Osati kudzifunsa funso la chifukwa ikulira thiransifoma, zitsanzo wamphamvu yonse ayenera kutenga apamwamba, wodziwika opanga. Low mphamvu si udzafunidwa pa olondola ntchito. Koma ngati ulipo pamene thiransifoma amapanga phokoso, mukhoza kuti muchotse izo ndi kutenga mbale ndi zomangira. kuyesa osati wotengeka osati delaminate zitsulo pachimake. Ngati akapichi palibe, ntchito misomali kapena zomatira, wodzala pachimake. Kuthetsa rattling windings n'chotheka mothandizidwa ndi rewinding awo.
