Surge arrester ndi mtundu wa overvoltage mtetezi, amene makamaka ntchito kuteteza zipangizo zosiyanasiyana magetsi (transformers, zosinthira, capacitors, zomangira, thiransifoma, jenereta, motors, zingwe mphamvu, etc.) mu kachitidwe mphamvu, njanji magetsi kachitidwe, ndi machitidwe kulankhulana. ... Chitetezo cha overvoltage mumlengalenga, ntchito overvoltage ndi mphamvu pafupipafupi chosakhalitsa overvoltage ndi maziko a mphamvu dongosolo kutchinjiriza mgwirizano.
Mfundo yogwiritsira ntchito disconnector
Pamene womangidwayo akugwira ntchito bwino, wotsegulayo sadzachitapo kanthu, kusonyeza kuperewera kwapansi, zomwe sizidzakhudza makhalidwe a chitetezo cha womangidwayo.Womangidwa ndi cholumikizira ndi otetezeka, osasamalira, osavuta komanso odalirika.Pali mitundu iwiri ya zolumikizira zomangira mphezi: mtundu wa kuphulika kotentha ndi mtundu wosungunuka wotentha.Cholumikizira chamtundu wotentha sichingathetsedwe mwachangu ngati chalephereka chifukwa cha zolakwika zake, kotero cholumikizira chamtundu wa kuphulika kotentha chimagwiritsidwa ntchito masiku ano.Chotsitsa choyambirira cha kuphulika kwa kutentha chinagwiritsidwa ntchito ndi GE monga chomangira valavu ya silicon carbide.Mfundo yake yogwirira ntchito ndikugwirizanitsa capacitor mofanana pa kusiyana kwa kutulutsa, ndipo chubu chophulika chamafuta chimayikidwa mu electrode yapansi ya kusiyana kwa kutulutsa.Pamene womangayo amagwira ntchito bwino, kutsika kwa mphezi ndi kugwiritsira ntchito mphamvu zamakono pa capacitor sikokwanira kuti kuwonongeke kwapakati, ndipo cholumikizira sichichita.Pamene womangayo awonongeka chifukwa cha vuto, kutsika kwamagetsi kwa mphamvu yafupipafupi yamagetsi pa capacitor kumapangitsa kuti kusiyana kwapakati kuwonongeke ndi kutulutsa, ndipo arc ikupitiriza kutentha chubu chophulika chamoto mpaka cholumikizira chikugwira ntchito.Komabe, pamakina osalowerera ndale omwe ali pamwamba pa 20A, cholumikizira chamtunduwu sichingatsimikizire kuti chimagwira ntchito pansi pamagetsi ang'onoang'ono.Chipangizo chatsopano chotulutsa ziboliboli chimagwiritsa ntchito varistor (silicon carbide kapena zinc oxide resistor) cholumikizidwa mofananira pagawo lotulutsa, ndipo chubu chophulika chamafuta chimayikidwa mu electrode yapansi.Pansi pa mphamvu yamagetsi yaying'ono, ma varistor amawotcha, amaphulitsa chubu chophulika, ndipo chipangizo chotulutsa chimagwira ntchito.
Mawonekedwe
1. Ndiopepuka kulemera, voliyumu yaying'ono, yosagwirizana ndi kugunda, umboni wa kugwa komanso kusinthasintha pakuyika, ndipo ndi yoyenera switchgear, ring network cabinet ndi zina zosinthira.
2. Zimapangidwa mophatikizana, popanda kusiyana kwa mpweya, ndi ntchito yabwino yosindikiza, chinyezi-chinyezi ndi kuphulika-kuphulika, ndi mawonekedwe apadera.
3. Mtunda waukulu wa creepage, kuthamangitsa madzi bwino, mphamvu zotsutsana ndi kuipitsidwa, kugwira ntchito mokhazikika, ndi kuchepa kwa ntchito ndi kukonza.
4. Fomula yapadera, kukana kwa zinc oxide, kutsika pang'ono, kuthamanga kwapang'onopang'ono komanso moyo wautali wautumiki
5. Mphamvu yeniyeni ya DC, mphamvu zamakono zamakono komanso kulolerana kwamakono ndizokwera kwambiri kuposa zomwe mayiko ndi mayiko ena amayendera.
Nthawi zambiri mphamvu: 48Hz ~ 60Hz
Kagwiritsidwe Ntchito
- Kutentha kozungulira: -40°C~+40°C
- Kuthamanga kwa mphepo: osapitirira 35m / s
- Kutalika: mpaka 2000 metres
- Kuchuluka kwa chivomerezi: osapitilira 8 madigiri
- Makulidwe a ayezi: osapitilira 10 metres.
- Magetsi ogwiritsidwa ntchito kwa nthawi yayitali sapitilira mphamvu yayikulu yopitilira ntchito
