Isishwankathelo
I-Surge arrester luhlobo lomkhuseli ogqithisayo, olusetyenziselwa ukukhusela izixhobo ezahlukeneyo zombane (iinguqu, iiswitshi, ii-capacitors, ukubamba, iziguquli, iijeneretha, iimoto, iintambo zombane, njl.njl.) kwiinkqubo zamandla, iinkqubo zombane zikaloliwe, kunye neenkqubo zonxibelelwano. ..) Ukukhuselwa kokugqithiswa kwe-atmospheric overvoltage, overvoltage esebenzayo kunye ne-frequency frequency transient overvoltage sisiseko solungelelwaniso logqume lwenkqubo yamandla.
Umgaqo wokusebenza wokuqhawula
Xa umbanjwa esebenza ngokuqhelekileyo, i-disconnector ayiyi kusebenza, ibonisa i-impedance ephantsi, engayi kuchaphazela iimpawu zokukhusela zombanjwa.Umbambisi one-disconnector ukhuselekile, ukugcinwa simahla, kulula kwaye kuthembekile.Kukho iindidi ezimbini zokuqhawula isibambisi sombane: uhlobo logqabhuko-dubulo olushushu kunye nohlobo lokunyibilika okushushu.Idizayini eshushu yokunyibilika eshushu ayinakukhutshwa ngokukhawuleza kwimeko yokusilela ngenxa yeziphene zayo zesakhiwo, ngoko ke isixhumi sohlobo logqabhuko-dubulo olushushu luqhele ukusetyenziswa namhlanje.Isixhumi sakwangoko sogqabhuko lwe-thermal sasetyenziswa yi-GE njengesibambisi sevalve ye-silicon carbide.Umgaqo wayo wokusebenza kukudibanisa i-capacitor ngokuhambelana kwi-gap yokukhupha, kwaye ityhubhu yokuqhuma kwe-thermal ifakwe kwi-electrode ephantsi ye-gap yokukhupha.Xa umbambeli esebenza ngokuqhelekileyo, ukuhla kwamandla ombane kunye nokusebenza kwe-impulse current kwi-capacitor akwanele ukwenza ukuchithwa kwe-gap yokukhupha, kwaye i-disconnector ayisebenzi.Xa umbambeli wonakele ngenxa yesiphoso, ukuhla kwamandla ombane we-voltage frequency fault current kwi-capacitor kwenza i-dicharge gap breakdown and discharge, kwaye i-arc iyaqhubeka nokutshisa ityhubhu yokuqhuma kwe-thermal de i-disconnector isebenze.Nangona kunjalo, kwiinkqubo ezingathathi hlangothi ezisekelwe ngokuthe ngqo ngaphezulu kwe-20A, olu hlobo lwe-disconnector alukwazi ukuqinisekisa ukuba lusebenza phantsi kombane omncinci wephutha langoku.Isixhobo esitsha sokukhupha isiqhushumbisi se-thermal sisebenzisa i-varistor (i-silicon carbide okanye i-zinc oxide resistor) edityaniswe ngokufanayo kwi-gap yokukhupha, kwaye ityhubhu yokuqhuma kwe-thermal ifakwe kwi-electrode esezantsi.Phantsi kwempazamo yangoku yamandla amancinci, i-varistor iyatshisa, iqhumisa ityhubhu yokuqhuma kwe-thermal, kunye nesixhobo sokukhulula sisebenza.
Iimbonakalo
1. Ilula ngobunzima, incinci ngomthamo, i-collision resistant, i-fall-proof kunye ne-flexible ekufakeni, kwaye ifanelekile kwi-switchgear, ikhabhinethi yenethiwekhi yendandatho kunye nezinye i-switchgear.
2. Yenziwe ngokudibeneyo, ngaphandle kwe-gap yomoya, kunye nokusebenza kakuhle kokutywinwa, ubungqina bomswakama kunye nokuqhuma, kunye nesakhiwo esikhethekileyo.
3. Umgama omkhulu we-creepage, i-repellency efanelekileyo yamanzi, isakhono esinamandla sokuchasa ungcoliseko, ukusebenza okuzinzileyo, kunye nokusebenza okucuthiweyo kunye nokugcinwa.
4. Ifomula eyahlukileyo, ukumelana ne-zinc oxide, ukuvuza okuphantsi kwangoku, isantya esicothayo sokuguga kunye nobomi benkonzo ende.
5. Awona mandla ombane ereferensi ye-DC, amandla ombane akhoyo ngoku kunye nonyamezelo oluphezulu lwangoku luphezulu kunemigangatho yesizwe kunye nemigangatho yamazwe ngamazwe.
