Umthelela wobude bekhamera kuNombolo yokuVikela yeDivaysi yokuVikela
Isihloko sokufakwa kwe-SPD akukhulunywa ngokungajwayelekile ezinkulumweni zethu. Kunezizathu ezimbili:
- Ukufakwa kwensimbi yokuvikela yokuhlinzwa kumele kuqhutshwe ngugesi ofanelekayo. Asifuni ukudukisa ukuthi lokhu kufanele kwenziwe ngabasebenzisi. Futhi uma i-SPD inentambo engalungile, ingadala ingozi.
- Kunamavidiyo amaningi ku-Youtube abonisa indlela yokufaka idivayisi yokuzivikela yokukhuphuka. Kuyinto elula futhi eqondile kunokufunda imiyalelo yombhalo.
Noma kunjalo, sibona iphutha elivamile kakhulu ekufakweni kwe-SPD, ngisho nokwenziwa kochwepheshe. Ngakho-ke kule ngqungquthela, sizoxoxa ngeseluleko esibaluleke kakhulu ekufakeni idivayisi yokuvikela ukuqhuma: ukugcina ikhebula libe mfushane ngangokunokwenzeka.
Kungani ubude bekhebula bubalulekile?
Ungazibuza lo mbuzo. Futhi kwesinye isikhathi sibuzwa amakhasimende ukuthi kungani ungenzi ubude bekhebula le-SPD libe lide? Uma wenza ubude bekhebula bubekhona, lapho-ke ngingafaka i-SPD kude kakhulu nephaneli yesekethe. Yebo, lokho okuphambene nanoma yimuphi umenzi we-SPD afuna ukwenze.
Lapha sethula ipharamitha: VPR (Voltage Protection Rating) noma Up (clamping voltage). I-former yangaphakathi kwe-UL futhi okulandelayo ku-standard ye-IEC. Ukungahloniphi umehluko wabo wezobuchwepheshe, baveza umbono ofanayo: kungakanani ngaphezu kwephethini i-SPD eyoyivumela ukuba idlule kwimishini engezansi. Ngolimi olufanayo, kuthiwa yi-let-through voltage.
Ubude bekhebula bunomthelela kumandla we-let-through. Ake sibheke izintambo ezimbili ezingezansi zokudlula.
Ungase ucabange ukuthi i-SPD yokuqala yenza okubi kakhulu kuneyesibili. Kodwa kuthiwani ngathi sikutshele ukuthi lezi yizona ezivumelekile ngokusebenzisa i-voltage ye-device efanayo yokuvikelwa kokukhuphuka? Yebo, lokhu kuyiqiniso. Lona idatha evela kusivivinyo esenziwa yi-EATON. Ngokukhulisa ubude bekhebula nge-3ft, vumela ukuphuma kwephethini cishe okuphindwe kabili okubonisa izinga eliphansi kakhulu lokuvikelwa kwimishini engezansi.
Kunomthetho jikelele ukuthi imitha ye-1 yekhebula ewela ngaphansi kwamandla ombane idala ukuvuthwa kwe-1,000V.
Isiphetho
Ubude bekhebula bunomthelela oqinile ezingeni lokuvikelwa kwedivayisi yokuvikelwa. Ngakho khumbula njalo ukugcina ikhebula libe mfushane ngangokunokwenzeka lapho ufaka idivayisi yokuvikelwa kokuqhuma. Uma kungenjalo, imali yakho yokutshala izimali ekuvikelweni komzimba ilahlekile futhi unomqondo wokuphepha wamanga kuphela.
