ELSF Series Fuse Mtundu Wodzipatula Chosinthira

Ma switch a ELSF series fuse-type isolation amagwira ntchito ndi ma fuse amtundu wa NH00 ndi NH01. Ali ndi voltage yogwira ntchito ya 0-500V DC ndi 0-690V AC yokhala ndi current yokwanira 800A. Current yogwira ntchito imasiyana malinga ndi kukula kwa fuse yomwe yagwiritsidwa ntchito.

Kugwiritsa ntchito

Mikhalidwe yachizolowezi yogwirira ntchito ndi mikhalidwe yoyikira

Kutentha kwa mpweya wozungulira sikuyenera kupitirira +50°C ndipo sikuyenera kupitirira -5°C.

Chinyezi: Kutentha kwakukulu kukafika +50 °C, chinyezi cha mpweya sichidutsa 50%. Chinyezi chambiri chimaloledwa kutentha kotsika, monga 90% pa 20 °C. Njira zapadera ziyenera kutengedwa kuti zisawonongeke nthawi zina chifukwa cha kusintha kwa kutentha.

Kuchuluka kwa kuipitsa kwa chilengedwe chozungulira ndi gawo lachitatu.

Chosinthiracho chiyenera kuyikidwa pamalo opanda kugwedezeka kwakukulu kutali ndi zinthu zoopsa komanso zoyaka moto.

Ili ndi IP30 ikatsekedwa ndipo IP20 ikatsegulidwa.

Kapangidwe

Chosinthiracho chimapangidwa ndi maziko, chivundikiro ndi mlatho wolumikizirana. Fuse imayikidwa mkati mwa chivundikirocho. Chivundikirocho chimatha kuzungulira ngati fan motsatira chithandizo. Chili ngati mtunda wautali wodzipatula wamagetsi kuti chikwaniritse zofunikira za chosinthira chodzipatula. Chivundikirocho chimatha kuchotsedwa mosavuta kuchokera pansi. Chimachotsedwa, zomwe zimapangitsa kuti zikhale zosavuta kuyika ndikuyikanso ulalo wa fuse.

Pali mabowo awiri omangirira pansi, omwe angakwaniritse zofunikira pakuyika m'makabati osiyanasiyana osinthira komanso pamapanelo. M'mbali zonse ziwiri za switch, ma contact othandizira amatha kuyikidwa ngati pakufunika kutumiza zizindikiro zosonyeza momwe switch imatsegukira komanso momwe imatsekera.

Chithunzi cha ELSF-160 chakunja

Kufotokozera mwatsatanetsatane:

Mndandanda wa ELSF uli ndi ma switch olimba a fuse-type isolating omwe amaphatikiza ntchito za cholumikizira ndi maziko a fuse, kuonetsetsa kuti chitetezo cha ntchito ndi chitetezo cha dera. Zipangizozi zimapangidwa kuti zigwiritsidwe ntchito ndi ma NH00 wamba (monga, NT00 RT16-00, max 160A) ndi NH01 (monga, NT1 RT16-1, max 250A) ma fuse links, omwe amathandizira ma rating osiyanasiyana a fuse kuyambira 4A mpaka 250A kutengera mphamvu yamagetsi yogwirira ntchito (AC: mpaka 690V; DC: mpaka 500V).

Chopangidwa kuchokera ku maziko, chivundikiro, ndi mlatho wolumikizirana, switch iyi idapangidwa kuti ikhale yolimba komanso yotetezeka. Chivundikirocho chimazungulira kuti chipange mtunda waukulu, wowoneka bwino, wokwaniritsa miyezo yokhwima ya isolator, ndipo chimachotsedwa mosavuta kuti chisinthidwe ndi fuse. Mayunitsiwa ali ndi voltage yodziyimira payokha (Ui) ya 1000V, voltage yopirira impulse (Uimp) ya 8kV, ndi current short-circuit rating yapamwamba ya 50 kA. Magawo ofunikira aukadaulo akuphatikizapo gulu logwiritsa ntchito la AC-21B/AC-22B kapena DC-22B, kulimba kwamagetsi kwa ma cycle 200, ndi kupirira kwamakina kwa ma cycle 1400. Ma model monga ELSF-160 ndi ELSF-250 ali ndi thermal current (Ith) ya 160A ndi 250A, motsatana, ndi kutaya mphamvu kwa 3.5W (160A) ndi 7.5W (250A) pa gawo lililonse popanda fuse.

Ma switch awa apangidwa kuti aikidwe m'malo omwe ali ndi digiri ya kuipitsidwa kwa 3, kutentha kozungulira kuyambira -5°C mpaka +50°C, komanso ma rating a chitetezo a IP20 (kutsegula chivundikiro) ndi IP30 (kutseka chivundikiro). Ndi oyenera kugwiritsa ntchito monga machitidwe a UPS, magetsi olumikizirana, ma capacitor banks, ndi ma network ogawa magetsi ambiri, zomwe zimapereka yankho lodalirika komanso lotetezeka pakuwongolera ma circuit.
