Ropa rehupenyu reTransformers: Kubva kuMafuta eMineral kusvika kuEsters dzechisikigo

Nhanganyaya

Oiri yetransformer inowanzonzi "ropa" retransformer. Inochengetedza, inotonhodza, inodzivirira, uye inotoongorora. Kwemakore anopfuura zana, mafuta emineral anobva mupetroleum ave ari sarudzo yakajairika. Asi kunetseka kuri kukura kwezvakatipoteredza uye zvinodiwa zvekuchengetedza moto zvakakonzera kugadzirwa kwemamwe mafuta - kunyanya, mafuta e ester echisikigo anobva muzvirimwa.

Chinyorwa chino chinotsvaga kushanduka kwe transformer insulating fluids uye chinotsanangura zvinorehwa nemusiyano uyu kune nyanzvi dzekutenga.

Kudzivirira kupisa.Basa guru nderekupa simba remagetsi pakati pezvinhu zvipenyu. Simba rayo guru re dielectric rinodzivirira ma short circuits uye kukuvara kwemagetsi.

Kutonhodza.Oiri inotenderera nepakati pemakonzo, ichitakura kupisa kuenda kuma radiator uko inonyangarika ichienda mumhepo.

Kudzima Arc.Kana paine zvikanganiso zvemukati, oiri inobatsira kudzima arc inobuda, ichidzivirira matambudziko madiki kuti asawedzere.

Dziviriro.Oiri inoita chipingamupinyi pakati pezvinhu zvesimbi neokisijeni, ichidzivirira ngura.

Kuongorora chirwere.Oiri inoshanda senzira yekutakura ruzivo. Kuongororwa kwegasi rakanyungudutswa kunoyera magasi anogadzirwa nemarudzi akasiyana ezvikanganiso, zvichipa yambiro yekutanga yematambudziko ari kuitika.

Chikamu Chechipiri: Oiri Yemigodhi—Mupimo Wekare wezana remakore

Yakanatswa kubva mupeturu isina kucheneswa, mafuta emineral ane zvakanakira zvitatu zvikuru: kuwanikwa pasi rose, mutengo wakaderera, uye simba rakanaka re dielectric.

Zvisinei, ine miganhu yayo. Nzvimbo yayo yekubatira moto yakaderera zvikuru—inenge 145°C kusvika 160°C—zvichikonzera njodzi yemoto munzvimbo dzine vanhu vakawanda. Inoora zvishoma nezvishoma, kazhinji 30 muzana chete, zvichireva kuti kudonha kwemvura kunogona kukonzera kukuvara kwezvakatipoteredza kwenguva refu. Uye sechigadzirwa chepetroleum, haidzokororwe.

Chikamu Chechitatu: Natural Esters—Nzira yeGreen Alternative

Zvichibva mumafuta e soya, mhodzi dzerape, nemamwe mafuta emuriwo, ma esters echisikigo ave ari emhando yepamusoro.

Kuchengetedzwa kweMoto.Maflash points anodarika 300°C—anopfuura kaviri mafuta emineral—zvichiita kuti akwanise kushandiswa mumaguta nemudzimba.

Kuenderana Kwezvakatipoteredza.Zvinoora nyore nyore, zvichisvika pakuora kwe97 muzana kana kupfuura mukati memavhiki.

Hupenyu Hwekudzivirira Hurefu.Bepa rakanyudzwa mu ester yechisikigo rinogona kugara kwenguva yakareba ka2.5 kusvika ka5 kupfuura mumafuta emaminerari kana paine kushushikana kwakafanana kwekupisa. Ma ester echisikigo anonwisa mvura yakawandisa iyo yaizokanganisa bepa uye kugadzira zvisungo zvinodzivirira nemamorekuru e cellulose.

Zvidzidzo zvinosimbisa zvakanakira izvi. Pa100°C kwenguva yakareba, ester yechisikigo yakaramba iine voltage yakakwira yekupwanyika kupfuura mafuta emaminerari uku ichiratidza simba rekudhonza uye resistivity yakasimba.

Chikamu Chechina: Kupfuura MaEsters Echisikigo—MaEsters Ekugadzira uye Matekinoroji Ari Kukura

Kune mamiriro ekunze anotonhora zvakanyanya uye makirasi emagetsi akanyanya, maester ekugadzira anopa kugadzikana kwakawedzerwa kweoxidation uye kushanda kwakaderera kwekushisa ukuwo achichengetedza zvakanakira nharaunda.

Muganho wekupedzisira unosanganisira nanotechnology. Titanium dioxide nanoparticles inogona kuderedza pour point kubva -5°C kusvika -32°C, zvichiita kuti kushandiswa kwemamiriro ekunze anotonhora kushandiswe. Hexagonal boron nitride nanosheets inovandudza thermal conductivity kusvika ku40 muzana. Iron-copper composite particles inowedzera breakdown voltage ne32 muzana. Kugadziriswa uku kunoratidza ramangwana apo maesters anoenderana kana kupfuura mineral oil muchikamu chega chega chekushanda.

Chikamu Cheshanu: Zvaunofanira Kufunga Nezvekusarudza Vatengi

Nzvimbo Yekushandisa.Kune nzvimbo dziri mukati, mumaguta, kana munzvimbo dzinonyanya kukanganiswa nezvakatipoteredza, ma esters echisikigo anotsigira kukosha kwawo kuburikidza nekuchengetedza moto uye kuderedza mutoro.

Mamiriro ekunze.Ma esters echisikigo ane viscosity yakakwira kupfuura mafuta emaminerari, izvo zvinogona kukanganisa kutonhora munzvimbo dzinotonhora. Matekinoroji ekuwedzera ari kuderedza musiyano uyu.

Mutengo uchienzaniswa neHupenyu Hwese.Pakutanga, maester echisikigo anodhura zvakanyanya, asi nguva yakareba yekudzivirira inogona kuderedza mari yese yekuva muridzi kwemakumi emakore.

Kutevedzera Mipimo.IEC 60296 inosanganisira mafuta emineral; IEC 62770 inosanganisira ma esters echisikigo. Vatengi vanofanira kuona kuti mvura inosangana nezvinodiwa.

Mhedziso

Oiri yetransformer yashanduka kubva pakugadzirwa kwepetroleum kuita mvura yakagadzirwa zvakanaka. Maester echisikigo ikozvino anopa kuchengetedzeka pamoto, kuenderana nezvakatipoteredza, uye hupenyu hwakareba hwekudzivirira husingakwanise kuenzana nemafuta emaminerari. Maester ekugadzira anosundira miganhu yekushanda zvakanyanya. Kune nyanzvi dzekutenga, kunzwisisa sarudzo idzi kwakakosha pakuita sarudzo dzine ruzivo.
