Khoom nta thiab Scope ntawm kev siv

Lub capacitor yog tsim los ntawm lub plhaub plhaub thiab lub hauv paus.Lub thawv plhaub yog ua los ntawm nyias steel phaj los ntawm kev sib khi thiab vuam.Lub thawv plhaub yog welded nrog lub qhov hluav taws xob lub tes tsho porcelain.Ob sab ntawm lub thawv phab ntsa yog welded nrog hangers rau installation, thiab ib sab ntawm lub hangers yog nruab nrog grounding bolts.Lub capacitor core yog tsim los ntawm laminating ob peb yam khoom thiab insulating qhov chaw, thiab cov khoom yog tsim los ntawm dov thiab flattening ob nplooj ntawv ntawm txhuas ntawv ci sandwiched daim ntawv composite nruab nrab los yog tag nrho cov zaj duab xis nruab nrab raws li polar daim hlau.Cov khoom nyob rau hauv cov tub ntxhais yog kev cob cog rua nyob rau hauv ib tug tej yam series thiab parallel hom kom tau raws li qhov yuav tsum tau ntawm txawv voltages thiab muaj peev xwm.Capacitors nrog fuses sab hauv, txhua yam khoom muaj fuse hauv series.Thaum cov khoom tawg, cov khoom siv tsis zoo txuas nrog nws yuav tawm mus, kom lub fuse yuav nrawm nrawm hauv milliseconds, thiab cov khoom tsis raug yuav raug tshuab tawm.txiav tawm, cia lub capacitor txuas ntxiv mus.Peb-theem capacitor yog lub hnub qub txuas.Cov kua nruab nrab hauv lub capacitor yog siv los impregnate cov khoom nruab nrab thiab sau cov voids hauv lub capacitor.Nws muaj cov khoom siv hluav taws xob zoo thiab lub cev thiab muaj kev sib raug zoo nrog lwm cov ntaub ntawv hauv lub capacitor.

Cov xwm txheej ua haujlwm:

Qhov siab tshaj qhov siab tsis tshaj 1000m, qhov kub thiab txias yog -40 / B, thiab qhov siab tshaj plaws ntawm chav kawm B yog +45 ℃.Lub chaw teeb tsa tsis muaj kev vibration loj heev, tsis muaj pa phem thiab chav dej, tsis muaj hluav taws xob lossis cov plua plav tawg.Capacitors yuav tsum tau lav tias yuav tsum tau ua haujlwm nyob rau hauv qhov cua zoo, thiab tsis tso cai rau ua haujlwm nyob rau hauv kaw thiab unventilated tej yam kev mob.Kev xaim ntawm cov khoom siv hluav taws xob yuav tsum yog cov neeg hloov pauv hloov pauv, thiab tag nrho cov hluav taws xob yuav tsum muaj kev sib cuag zoo.

Ordering cov ntaub ntawv

Kev xaiv ntawm qhov ntsuas hluav taws xob ntawm lub capacitor yuav tsum yog raws li lub network voltage.Xav tias cov tswv yim ntawm lub capacitor yuav nce qhov voltage, yog li thaum xaiv qhov ntsuas hluav taws xob ntawm lub capacitor, nws yog qhov tsawg kawg yog 5% siab dua qhov hluav taws xob network;Thaum muaj ib lub reactor nyob rau hauv lub capacitor Circuit Court, lub davhlau ya nyob twg voltage ntawm lub capacitor Lub hauv av nce nrog cov reactance tus nqi ntawm lub reactor nyob rau hauv series, yog li thaum xaiv qhov ntsuas voltage ntawm lub capacitor, nws yuav tsum tau txiav txim siab tom qab xam raws li tus nqi reactance. ntawm lub reactor nyob rau hauv txoj hlua.Capacitor yog cov kab uas tsis tshua muaj impedance ntawm harmonics.Nyob rau hauv harmonics, ib tug loj npaum li cas ntawm harmonics yuav raug txhaj rau hauv lub capacitor kom lub capacitors overcurrent los yog overvoltage.Tsis tas li ntawd, cov capacitors yuav ua rau kom muaj kev sib haum xeeb thiab ua rau lub suab nrov thaum lawv tas sij hawm, ua rau muaj kev phom sij rau kev nyab xeeb ntawm daim phiaj hluav taws xob thiab ua rau cov capacitors lifespan.Yog li ntawd, capacitors nrog loj harmonics yuav tsum tau siv nyob rau hauv reactors uas suppress harmonics.Lub inrush tam sim no thaum lub capacitor kaw yuav siab li ntau pua zaus ntawm cov ntsuas tam sim no ntawm lub capacitor.Yog li ntawd, qhov hloov pauv rau kev hloov pauv lub capacitor yuav tsum xaiv qhov hloov pauv yam tsis muaj kev rov ua dua.Txhawm rau txhawm rau txhawm rau kaw qhov hluav taws xob tam sim no, lub reactor uas suppresses lub inrush tam sim no tuaj yeem txuas nrog hauv series.Tom qab lub capacitor nrog kev tso tawm sab hauv yog txiav tawm ntawm lub hwj huam mov, nws tuaj yeem poob los ntawm tus nqi siab tshaj ntawm qhov ntsuas hluav taws xob mus rau qis dua 75V hauv 10 feeb.yuav piav thaum twg.Capacitors siv rau kab them nyiaj yuav tsum tau nruab rau ntawm 150 ~ 200kvar nyob rau hauv ib qho chaw, thiab ceev faj tsis txhob nruab lub capacitors nyob rau tib theem li transformer, thiab tsis txhob siv tib pab pawg ntawm dropouts los tiv thaiv overshooting los ntawm ferromagnetic resonance thaum lub kab tsis khiav hauv txhua theem.Tam sim no overvoltage tuaj yeem ua puas lub capacitors thiab transformers.Zinc oxide surge arrester rau kev tiv thaiv kev khiav hauj lwm overvoltage yuav tsum raug xaiv rau zinc oxide surge arrester mob siab rau lub capacitor, thiab nws yog qhov zoo tshaj rau nruab nws ntawm lub capacitor ncej.Lub fuse tshwj xeeb uas siv rau lub capacitor raug xaiv rau kev nrawm nrawm, thiab qhov ntsuas tam sim no yuav tsum raug xaiv raws li 1.42 ~ 1.5 npaug ntawm qhov ntsuas tam sim no ntawm lub capacitor.Thaum lub capacitor txuas ncaj qha mus rau lub high-voltage motor nyob rau hauv parallel, txhawm rau tiv thaiv tus kheej-excitation thaum lub cev muaj zog disconnected los ntawm lub hwj chim mov, ua rau lub voltage ntawm lub capacitor davhlau ya nyob twg yuav nce siab tshaj tus nqi ntsuas, ntsuas tam sim no. ntawm lub capacitor yuav tsum tsawg dua 90% ntawm qhov tsis muaj load tam sim no ntawm lub cev muaj zog;Thaum siv Y / △ xaim, nws tsis raug tso cai los txuas lub capacitor ncaj qha rau lub cev muaj zog nyob rau hauv parallel, thiab yuav tsum tau txais yuav ib txoj kev tshwj xeeb.Thaum lub capacitor siv nyob rau ntawm qhov siab siab tshaj 1000 meters los yog lub capacitor yog siv nyob rau hauv lub cheeb tsam sov, nws yuav tsum tau hais thaum txiav txim.Cov ntawv pov thawj tshwj xeeb spe lossis cov cai tshwj xeeb rau cov capacitors yuav tsum tau teev thaum xaj.
