Kuphulika kwa Transformer Tsopano Kungathe Kuletsedwa Kusanachitike - Njira Yoyamba Yotetezera Yogwira Ntchito ku China Yayamba Kugwira Ntchito

Chiyambi

Pa 27 June 2026, njira yoyamba yotetezera ku China yopewera zolakwika za transformer idakhazikitsidwa ku Tianjin South UHV substation.

Izi si kungokhala kusintha kwina kwa zida. Zimasintha mfundo yopewera kuphulika kwa transformer kuchokera pa "kuzimitsa moto ukayamba" kupita ku "kuwudula usanachitike."

Chifukwa Chake Chitetezo Chachikhalidwe Sichinathe Kuletsa Kuphulika kwa Mphepo

Transformer yaikulu imakhala ndi matani makumi mpaka mazana ambiri a mafuta oteteza kutentha. Pamene mphamvu zambiri zituluka mkati, kupanikizika mkati mwa thanki kumatha kukwera kwambiri, zomwe zimayambitsa kuphulika kapena moto.

Vuto ndi chitetezo chachikhalidwe ndi nthawi. Chitetezo chosiyana ndi ma Buchholz relay amagwira ntchito pokhapokha ngati chotenthetsera chawonongeka kale. Amatha kudula mphamvu, koma pofika nthawi yomwe achita izi, kuphulika kungakhale kuti kwayamba kale.

DGA ya pa intaneti imatha kuzindikira zolakwika zoyambirira, koma kufalikira kwa mpweya kumatenga nthawi. Singathe kugwira mtundu wa kutulutsa komwe kumachitika mu ma millisecond. Chitetezo chachikhalidwe nthawi zonse chimakhala ndi kusiyana kwa nthawi - ndipo kusiyana kumeneko nthawi zambiri kumakhala masekondi ochepa pakati pa "cholakwika chowongolera" ndi "kutayika konse."

Momwe Dongosololi Limagwirira Ntchito

Lingaliro lalikulu ndi losavuta:sunthani chingwe chotetezera patsogolo - chitanipo kanthu chisanawonongeke chotetezera.

Dongosololi limagwiritsa ntchito mitundu itatu ya masensa otulutsa mpweya pang'ono pa transformer ya ma frequency apamwamba, ma ultrasound, ndi ma ultra-high-frequency - kuti ayang'anire ma signal otulutsa mpweya nthawi yomweyo. Pambuyo pa zaka zisanu za chitukuko, gululi linazindikira ndikuchotsa mitundu 16 ya kusokoneza, kuphatikizapo kusintha kwa ntchito ndi korona wakunja, ndipo linapanga njira yowunikira yokhudza kuopsa kwa kutulutsa mpweya, kuchuluka kwa kukula, kupitirira, ndi kulumikizana kwa magetsi a acoustic.

Kutengera ndi gawo la chitukuko cha kutulutsa madzi, dongosololi limayambitsa alamu yonse, alamu yoopsa, kapena kutsika kwa chitetezo.

Mwachidule: chitetezo chachizolowezi ndi thumba la mpweya lomwe limagwira ntchito pambuyo pa ngozi. Dongosololi ndi braking yokha yomwe imazindikira zoopsa ndikuyimitsa galimoto isanagunde.

Zaka Zisanu Zachitukuko, Zaka Zitatu Zopanda Ulendo Wolakwika

Dongosololi silinapangidwe mu labotale. Gulu la mazana ochokera m'mabungwe 31, lotsogozedwa ndi State Grid North China Branch, linatha zaka zisanu pa kafukufuku ndi chitukuko.

Mu gawo loyesera, makinawo ankangotumiza ma alarm. Sanagwe. Kuti asinthe kuchoka pa alarm kupita ku ina, makinawo ankayenera kukwaniritsa miyezo yodalirika ya chitetezo. Gululo linasintha makinawo ndi mapangidwe awiri osasinthika ndikusintha ma algorithms oteteza.

Dongosololi linayesedwa pa ma transformer enieni m'mayesero 171 omwe adabwerezanso momwe zinthu zinalili zenizeni. Linagwira ntchito bwino nthawi iliyonse. Chofunika kwambiri, mayunitsi 33 omwe adayikidwa m'malo osinthira magetsi adayesedwa kwa zaka zitatu, atakumana ndi zochitika zopitilira 1.8 miliyoni zosokoneza, popanda kusokonekera kulikonse kolakwika.

Gulu la akatswiri owunikira linayang'ana ntchitoyi ndipo linatsimikizira kuti ukadaulo wonse wafika pamlingo wapamwamba padziko lonse lapansi.

Mapeto

Kuchokera pa “thumba la mpweya pambuyo pa ngozi” mpaka “kutseka mabuleki okha musanachite ngozi,” mfundo yopewera kuphulika kwa transformer yasinthidwa. Kufunika kwa dongosololi sikuti ndi luso lokha - ndi kusintha momwe timaganizira za chitetezo cha magetsi: kusuntha mzere woteteza patsogolo, ndikudula cholakwikacho chisanakhale tsoka. Ukadaulowu ukugwiritsidwa ntchito kale pa transformers pa 110 kV ndi kupitirira apo, ndipo ukukonzekera kuyambitsidwa ku Hebei, Shanxi, Anhui, ndi madera ena.
