Fais fab teeb meem yog tias muaj xob quaj nyob hauv thaj chaw nyob deb nroog? Tej zaum tus transformer tsis npaj rau xob laim tiv thaiv
Nyob rau hauv miao lub zos hauv Guizhou, thaum twg cov huab daj cua dub tau ploj mus rau lub qhov rooj nkag, tus xeb ntawm lub zos yuav nyob rau lub sijhawm "tawm tsam". Kev Kho Cov Kev Kho Mob Cov Ntaub Ntawv Qhia tias lub zos tau paub dhau 27 lub zog ntawm peb lub xyoos ntawm lub zog hluav taws xob, tsis muaj sijhawm tsis muaj 8 hnub. Qhov no tsis yog ib rooj plaub sib cais - Cov phiaj xwm National
I. Nraum: Tus Killer Tsis Pom Tus Kheej
Xob laim tawm tsam tam sim ntawd tsim kom muaj kev poob siab tawm rau cov cuaj luaj me me. 1 {0} ka xob laim windinged rau hauv transformer windinged hauv 0.1 vib nas this, lub kauj tig-rau-tig voltage mus txog 20 zaug ua haujlwm voltage. Qhov kev tiv thaiv no yog tam sim no tsunami, tuaj yeem tawg tam sim no los ntawm kev laus rwb thaiv tsev daim ntawv, ua rau muaj kev luv luv ntawm cov thib. Kev tawm lub roob hluav taws xob ntawm lub roob hloov pauv tau hais tias qhov tob thaiv hluav taws kub ntawm 3mm tom qab raug coj los ntawm xob laim, sib npaug rau cov khoom siv lub neej luv los ntawm 15 xyoos.
Qhov chaw hauv av tsis ua haujlwm yog lub suab nrov ntawm xob laim kev puas tsuaj. Kev pom tau pom tias muaj qee qhov chaw hloov hluav taws xob deb ntawm thaj chaw tiv thaiv kom ntau li 48ω, deb tshaj 10ω tus qauv kev nyab xeeb. Qhov no yog sib npaug rau kev tsim kho ntawm xob laim "txoj kev loj", tsis muaj kev tawm tsam rau hauv lub ntiaj teb no mus rau hauv "Hluav Taws Kub", ua rau cov saw hluav taws xob.
II.Qhov kev tiv thaiv xob laim ntawm lub "Triple Lowophole"
Xob Laim Arrester kev laus uas yog qhov tsis ua tiav ntawm "Xob Laim". Ib lub zos siv lub valve-hom xob laim tau txais kev pabcuam rau 12 xyoos, kev kuaj mob voltage txo los ntawm 35%, cov nqi hluav taws xob rov qab nce rau 4.8KV. Lub xeev no ntawm xob laim lub sij hawm teb kev teb ncua sij hawm ncua ntawm {5}}.
Rwb thaiv tsev haum cov teeb meem exacerbate khoom puas. Transformer casing cropage nrug yog tsawg dua 18mm / kV, los nag saum npoo av tam sim no yuav nce peb zaug. Kev sib tsoo xob laim, vim yog cov dab tsi ntawm lub rwb thaiv tsev sab nraud uas tsis muaj zog tam sim no, thiab thaum kawg}
Tsis muaj txoj kab tiv thaiv kab los ua "xob laim channel". Thaum cov neeg ua haujlwm tshaj tawm kev ncua deb tshaj 150 meters, induction overVoltage zog nce los ntawm 60%. Ib lub zos hauv Guangxi 10kV kab vim tsis muaj qhov tsis muaj kev teeb tsa ntawm overhead av kab, xob laim tus nqi yog 2.7 zaug ntawm kab txheem. Kev tawm tsam kev nyab xeeb yog tsawg dua 3 meters, ntoo flash yuav ua rau lub zog thib ob.
III.Qhov kev tsim kho ntawm xob laim tiv thaiv "Golden tswb"
Tshiab xob laim cov khoom tiv thaiv los coj kev tsim kho thev naus laus zis. Zinc oxide xob laim, siv ntau yam kev sib txawv, cov qauv hluav taws xob uas seem yuav raug tswj hwm hauv qab 2.3kv. Cov cuab yeej txawj ntse cuam tuaj yeem lees paub txog cov yam ntxwv ntawm kev tawm tsam yoj nrog nthwv dej thiab muab tso rau hauv cov tshuaj tiv thaiv tam sim no tsis pub dhau 16ms. Tom qab kev txhim kho cov xob tiv thaiv kev tiv thaiv sib xyaw ua ke hauv lub tuam tsev tsav tsheb hauv lub zos tsav, xob laim khiav tawm ntawm tus nqi 82%.
Kev sib txuas hauv av network yog lub hauv paus ntawm xob laim kev tiv thaiv. Kev siv tooj liab-coated steel grounding lub cev nrog kev tsis kam-txo tus neeg sawv cev, tuaj yeem ua rau lub hauv paus tsis kam ruaj ntawm 4ω lossis tsawg dua. Peb-seem av network tsim kev sib xyaw ua ke cov kab rov tav hluav taws xob thiab cov av nplaum av kom tsim kom muaj peb-sab nraud dej ntws channel. Tom qab kev hloov pauv ntawm lub roob hloov pauv, qhov kev cuam tshuam implyance ntawm cov av hauv av yog txo rau 7,ω, thiab cov xob laim tam sim no nce los ntawm 65%.
Kev saib xyuas cov kev tu cov kab kawg ntawm kev tiv thaiv. Kev kuaj cov koob yees duab hluav taws xob tsis tu ncua ntawm lub koob yees duab thermal no tuaj yeem ntes tau ib qho kis tau kub siab ntawm}. 5 Qib tuaj yeem ntes cov cim paug hauv 30PC. Lub chaw muab hluav taws xob muaj zog kho kom haum rau cov khoom siv hluav taws xob rau 85% ntawm cov khoom tshiab los ntawm kev ntxuav cov insulators ntawm kev sib tw av. Kev kho mob corrosion ntawm cov xov hlau hmoov av txuas ntxiv lub neej ntawm lub hauv paus av hauv lub cev mus rau 25 xyoo.
Nyob rau hauv ib lub zos kob nyob rau hauv Fujian, tus hloov pauv tom qab tsim kev tiv thaiv kev tiv thaiv tau muaj kev nyab xeeb rau 1400 hnub sib law liag. Thaum peb pom tus hloov pauv ntawm nag hmo xob laim pom kev yooj yim, tab sis kuj tseem niaj hnub tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv lub pob caus ntawd. Tus Suav Academy ntawm hluav taws xob hluav taws xob kwv yees tau hais tias nrog cov khoom lag luam hauv av graphene thiab cov hluav taws xob ruaj khov ntawm cov qib hauv nroog yuav poob rau qib hauv nroog tsis pub dhau tsib xyoos. Lwm zaus muaj lub tshuab cua daj cua dub hlob, cov hloov pauv no, lossis yuav hloov mus ua tus saib xyuas ntawm lub teeb ntawm tus tiv thaiv steel.
