Isishwankathelo
I-Arrester ngumkhuseli ogqithisayo, osetyenziselwa ukukhusela izixhobo zombane ezahlukeneyo (i-transformer, i-switch, i-capacitor, i- arrester, i-transformer, i-generator, i-motor, intambo yamandla, njl.njl.) iinkqubo ezifana nenkqubo yamandla, inkqubo yombane kaloliwe kunye nenkqubo yoqhagamshelwano I-atmospheric overvoltage, i-operation overvoltage kunye ne-frequency frequency overvoltage yamandla sisiseko solungelelwaniso lokufakelwa kwenkqubo yamandla.Izinto zayo eziphambili ziyi-zinc oxide.Umbambeli wombane udla ngokudityaniswa phakathi komqhubi wegridi kunye nocingo oluphantsi komhlaba, kwaye ngamanye amaxesha udityaniswe kufuphi nombane okanye phakathi kwabaqhubi.
Into engundoqo (i-resistor) ye-metal oxide arrester (MOA) ithatha ifomyula ephuculweyo esekwe kwi-zinc oxide, eneempawu ezigqwesileyo ezingezizo (volt ampere), oko kukuthi, phantsi kombane osebenzayo oqhelekileyo, ukudlula ngoku kukwinqanaba le-micro ampere kuphela. .Xa i-over-voltage ifunyenwe, i-current passing inokufikelela kumawaka e-ampere ngokukhawuleza, ngoko ke umntu obambayo ukwimeko yokuqhubela phambili kwaye akhuphe amandla angaphezulu kwe-voltage, ngaloo ndlela ethintela ngokufanelekileyo umonakalo wombane ogqithisiweyo kumbane wokuhambisa kunye nezixhobo zokuguqula.
Isibambisi seSiC esiqhelekileyo sinengxaki yombane wokukhupha amaza aphezulu ngenxa yokulibaziseka kokukhutshwa kwamaza, kunye nombane osebenza kakhulu wokukhupha amaza ngenxa yosasazo olukhulu lokukhutshwa kwamaza okusebenza.Isibambi seZinc oxide sineengenelo zokusabela kakuhle kwamaza amaza, akukho kulibaziseka kumandla ombane angamaza, umbane oshiyekileyo osezantsi, akukho kusasazwa kokuphuma, njl. njl.Ngokumalunga nolungelelwaniso lokugquma, imida yokhuselo lwamaza amaza, amaza ombane kunye namaza okusebenza angaphantse afane, ukuze abonelele ngolona khuseleko lubalaseleyo lwezixhobo zamandla.
Isibambisi sesinyithi esine-sheathed metal oxide sisebenzisa inkqubo yokubumba iyonke yokupakishwa kweziphelo ezimbini, enokusebenza kakuhle kokutywina, ukusebenza kakuhle kobungqina bokudubula, ukumelana nongcoliseko, akukho mfuneko yokuyicoca, inokunciphisa ukwenzeka kokukhanya okumanzi kwiintsuku ezinenkungu, kwaye ukuxhathisa kwi-corrosion yombane, ukuguga, ubungakanani obuncinci, ukukhanya kobunzima, kwaye kulula ukuyifaka kunye nokugcina.Ithatha indawo yesibambisi seporcelain bushing.
Iimbonakalo
1. Ubungakanani obuncinci, ubunzima bokukhanya, ukuchasana nokungqubana, akukho monakalo, ukufakwa okuguquguqukayo, okufanelekileyo kwi-switchgear
2. Isakhiwo esikhethekileyo, ukubumba ngokubanzi, akukho msantsa womoya, ukusebenza kakuhle kokutywinwa, ubungqina bokufuma kunye nokuqhuma
3. Umgama omkhulu we-creepage, i-repellency efanelekileyo yamanzi, isakhono esinamandla sokuchasa ungcoliseko, ukusebenza okuzinzileyo, kunye nokusebenza okucuthiweyo kunye nokugcinwa.
4. I-zinc oxide resistor, ifomyula ekhethekileyo, ukuvuza okuncinci okwangoku, ukuguga okucothayo, iimpawu zokuphendula ezilungileyo, akukho ngoku okuqhubekayo, umthamo wangoku omkhulu, i-voltage ephantsi eshiyekileyo, amandla anamandla okucinezela i-overvoltage, ukumelana nongcoliseko, ukulwa nokuguga, ukukhululeka kwimithintelo yokuphakama. , isakhiwo esilula, akukho sithuba, ukutywinwa okuqinileyo, ubomi obude kunye nezinye iimpawu.
5. Owona mbane wereferensi we-DC, amandla ombane akhoyo ngoku kunye nonyamezelo oluphezulu lwangoku luphezulu kunemigangatho yamazwe ngamazwe
6. Ngaphantsi kwe-voltage yesiqhelo yokusebenza kwenkqubo, lo mbambeli ubonisa imeko ephezulu yokumelana, kwaye kuphela i-microamp yangoku idlulayo.Ngaphantsi kwesenzo se-over-voltage kunye ne-current enkulu, ibonisa ukuchasana okuphantsi, ngaloo ndlela inciphisa i-voltage eseleyo kuzo zombini iziphelo zokubamba.
Imiqathango yokusetyenziswa
- Ubushushu be-Ambient: -40°C~+40°C
-Esona santya somoya: hayi ngaphezulu kwe-35m/s
-Ukuphakama: ukuya kuthi ga kwi-2000 yeemitha
- Ubunzulu benyikima: akukho ngaphezu kwe-8 degrees
- Ubukhulu bomkhenkce: hayi ngaphezulu kweemitha ezili-10.
- I-voltage esetyenzisiweyo yexesha elide ayigqithisi ubuninzi be-voltage eqhubekayo yokusebenza.
