Impembelelo Ubude beChethri kwiNqanaba loKhuseleko lweDiskhi yokuKhusela
Isihloko sofakelo lwe-SPD asiqhelwanga ngokungaqhelekanga kwiingxoxo zethu. Kukho izizathu ezibini:
- Ukufakwa kwesixhobo esikhuselayo sokukhusela kufuneka kuqhutywa ngunombane ofanelekileyo. Asifuni ukulahlekisa ukuba oku kufuneka kwenziwe ngabasebenzisi. Kwaye ukuba i-SPD i-wiring engalunganga, inokubangela ingozi.
- Kukho iividiyo ezininzi kwi-Youtube ezibonisa indlela yokufaka ifowuni yokukhusela. Kulula kakhulu kwaye ilungile kunokuba ufunde imiyalelo yombhalo.
Sekunjalo, siyaqaphela iphutha eliqhelekileyo kwi-SPD yokufakela, kwanokwenziwa ngabafundi. Ngaloo nqaku, siza kuxoxa ngesikhokelo esibalulekileyo ekufakekeni kweso sixhobo sokukhusela: ukugcina ikhefu imfutshane nje ngangokunokwenzeka.
Kutheni kubalulekile ubude bekhebula?
Unokuzibuza lo mbuzo. Kwaye ngamanye amaxesha sibuzwa ngabathengi ukuba kutheni ungenzi ubude bekhebula le-SPD? Ukuba wenza ubude bekhebula, emva koko ndingafaka i-SPD kancinane kude nephaneli yesekethe. Ewe, ngokwahlukileyo kuyo nayiphi na into eyenziwe ngumenzi we-SPD ofuna ukuba uyenze.
Apha sazisa ipharamitha: VPR (Umlinganiselo woKhuseleko lweVoltage) okanye Phezulu (i-clamping voltage). Eyangaphambili kumgangatho we-UL kwaye yamva ikumgangatho we-IEC. Bengawuhoyi umahluko wabo wobugcisa, bavakalisa imbono efanayo: ingakanani i-voltage engaphaya kwe-SPD eya kuvumela ukuba idlule kwisixhobo esisezantsi. Ngolwimi oluqhelekileyo, ikwabizwa ngokuba yi-let-through voltage.
Ubude bentambo bunempembelelo kwi-voltage ye-let-through. Makhe sijonge ezi zimbini zingezantsi zombane.
Unokucinga ukuba iSPD yokuqala yenza kakubi kakhulu kuneyesibini. Kodwa kuthekani malunga nokukuxelela ukuba ezi zivumela umbane wesixhobo esifanayo sokukhusela? Ewe, oku kuyinyaniso. Le yidatha evela kuvavanyo olwenziwe yi-EATON. Ngokunyusa ubude bentambo nge-3ft, i-let through voltage iphantse iphindeke kabini ebonisa inqanaba elibi kakhulu lokhuseleko kwisixhobo esisezantsi.
Kukho umgaqo oqhelekileyo wokuba imitha ye-1 yentambo egqitywe ngumbane wangoku ivelisa i-overvoltage ye-1,000V.
isiphelo
Ubude bekhebula bunempembelelo enamandla kumgangatho wokukhusela wesixhobo sokukhusela sokunyuka. Ke hlala ukhumbula ukugcina intambo imfutshane kangangoko xa ufaka isixhobo sokhuselo lotyando. Ngaphandle koko, utyalo-mali lwakho kukhuseleko lokutyakala luchithiwe kwaye unemvakalelo yobuxoki yokhuseleko.
