Current Transformer Secondary Overvoltage Protector
kuchuluka kwa ntchito
Chitetezo chamakono cha transvoltage chachiwiri ndichoyenera kupiringa mosiyanasiyana, kupindika mopitilira muyeso, kupindika, kupindika kwachitetezo chamabasi ndi mapindikidwe osungira a mbali yachiwiri ya CT.Izo ntchito ziletsa osakhalitsa overvoltage m'munsimu zimakhudza overvoltage wa zida ndi kutulutsa mphamvu mafunde, kuteteza dongosolo dera ndi zida.
Normal utumiki zinthu ndi unsembe mikhalidwe
1. Mikhalidwe yautumiki wamba
a.Voltage: Mphamvu yamagetsi yomwe ikugwiritsidwa ntchito mosalekeza pakati pa ma terminals oteteza voteji sayenera kupitilira kuchuluka kwake
Chachikulu mosalekeza voteji ntchito.
b. Kutentha kozungulira: -20 ℃ ~ 70 ℃.
c.Chinyezi chozungulira chomwe chimagwiritsidwa ntchito: <95%RH.
d. Mulingo wachitetezo cha nyumba: IP20.
e.Pollution level: Mulingo woyipitsidwa pamalo oyikapo ndi gawo 2.
2. Kuyika zinthu
Gulu la a.Installation: molingana ndi mlingo wa chitetezo chamagetsi a chipangizo chotetezera cha overvoltage chagawidwa m'magulu awiri;
b.installation site:

| njira kukhazikitsa | Mtundu wama track |
1. Yalangizidwa pamasamba omwe sanawonekere;
2. Idzakhazikitsidwa popanda kugwedezeka kwakukulu ndi kukhudzidwa.
3. Njira yoyika: gwiritsani ntchito njanji yamtundu wa TH35-7.5 pakuyika.
4. Wiring mode: screw kukanikiza mawaya.
Mawonekedwe ndi kukula kwa kukhazikitsa
Kukula konse: 115 * 90 * 40 (kutalika * m'lifupi * kuya) (CTB-6) unit: mm
Njira yoyika: kuyika njanji yowongolera
