Chifukwa chiyani ma transfoma amafunikira kuwongolera kutentha?

Zosinthazili ngatiZithunzi za MVPyamagetsi, kusamutsa magetsi kuchokera kudera lina kupita ku lina. Amabwera m'mawonekedwe ndi makulidwe onse, kuphatikiza ma frequency apamwamba opangidwa ndi zokongolaopanga ma thiransifoma. Chinthu chimodzi chachikulu chomwe chimakhudza momwe transformer imagwirira ntchito komanso kutalika kwake ndikukwera kwa kutentha. Zikafika pa nthawi ya moyo wa thiransifoma, choyambitsa chachikulu cha ukalamba wotsekereza ndi kutentha. Chifukwa kutentha sikufalikira mofanana mkati mwa thiransifoma, mbali zosiyanasiyana zimatha kutentha mosiyanasiyana. Chifukwa chake, thiransifoma iyenera kukhala pamtolo wovotera, kutentha kwa gawo lililonse kumatchulidwa-uku kumatchedwa kukwera kovomerezeka kwa kutentha.

Kuwongolera kutentha kwa transformer ndikofunikira kwambiri. Choyamba, kutentha kwambiri kungapangitse kuti kutchinjiriza kusakhale kothandiza ndikufupikitsa moyo wonse wa thiransifoma. Kuphatikiza apo, kutentha kwambiri kumatha kupangitsa kuti zinthu zichuluke komanso ziwonjezeke, kuyika kupsinjika pazigawo ndikuziwononga. Pamwamba pa izo, kutentha kwapamwamba kumapangitsanso kutaya mphamvu zambiri, zomwe zimapangitsa kuti transformer ikhale yochepa komanso yokwera mtengo kuyendetsa.

Nthawi zambiri, ma transfoma omizidwa ndi mafuta amagwiritsa ntchito kutchinjiriza kwa Gulu A, ndipo kutentha kovomerezeka ndi 105 ° C. Kutengera 40 ° C m'chilimwe monga muyezo, kutentha kovomerezeka kwa koyilo ndi 65 ° C. Popeza kutentha kwa thiransifoma nthawi zambiri kumakhala kotsika kwa 10 ° C kuposa momwe zimakhalira, kutentha kovomerezeka kwa thiransifoma ndi 55 ° C. Mwanjira iyi, ziribe kanthu momwe mpweya wozungulira umasintha, malinga ngati kutentha kwa kutentha sikudutsa mtengo wovomerezeka, transformer ikhoza kutsimikiziridwa kuti ikugwira ntchito motetezeka mkati mwa moyo wautumiki wotchulidwa.

Kuti athane ndi vutoli, opanga zamagetsi a XuanGe amagwiritsa ntchito njira zamitundumitundu. Kusuntha kwakukulu komwe amapanga ndikusankha zida zokhala ndi matenthedwe abwino kwambiri a zinthu monga pachimake ndi mapindikidwe a thiransifoma - izi zimathandiza kuchotsa kutentha kwambiri ndikuchepetsa kutentha. Ndipo palinso zinthu zina zomwe zimapangidwa m'mapangidwe a thiransifoma makamaka kuti aziziziritsa zinthu: ganizirani zipsepse zoziziritsa kapena mafuta kapena makina oziziritsira mpweya kuphatikiza masensa omwe amasunga nthawi kuti azikhala motetezeka.

Pamwamba pamalingaliro onsewa, opanga zamagetsi a XuanGe amatsatiransomiyezo ndi malamulo amakampaniZomwe zimawonetsa momwe kutentha kwa thiransifoma kumaloledwa kulowa m'malo ogwirira ntchito bwino - miyezo iyi imawonetsetsa kuti ma transfoma apangidwa m'njira zomwe zimawalola kuti azigwira ntchito motetezeka pakanthawi kochepa komanso amakhala kwautali momwe angathere popanda kusweka kapena kuyambitsa. mavuto.

Zikomo powerenga mpaka pano. Ndikufunirani bizinesi yopambana komanso moyo wabwino.
