Amadivayisi wokukhiyazingamathuluzi abalulekile okuqinisekisa ukuphepha kwabasebenzi lapho belungisa noma belungisa izinto zikagesi.Zivimbela ukwenziwa kusebenze ngengozi kwemishini noma okokusebenza okungase kubangele ukulimala kubasebenzi.Kunezinhlobo ezimbalwa zamadivayisi wokukhiya atholakalayo, ngayinye yakhelwe izinhlelo zokusebenza ezithile.Kulesi sihloko, sizohlola izinhlobo ezahlukene zamadivayisi wokukhiya, ngokugxila ekukhiyeni kwe-loto namadivayisi wokuvala ama-circuit breaker.
Izingidi ze-loto, ezaziwa nangokuthilockout/tagout locks, zingenye yezinhlobo ezivame kakhulu zamadivayisi wokuvala ngaphandle.Asetshenziselwa ukukhiya imithombo yamandla ngaphandle ngokuvikelekile, njengamaswishi kagesi, amavalvu, noma okokusebenza, ukuvimbela ukusebenza kwengozi noma okungagunyaziwe.Lezi zingidi ziza ngezitayela ezahlukene, okuhlanganisa izingidi, izingidi ezihlanganisiwe, nezikhiye zokhiye, futhi ngokuvamile zenziwe ngezinto ezihlala isikhathi eside njengensimbi noma i-aluminium ukuze zimelane nezindawo zezimboni ezinokhahlo.
Uma kufikaamadivaysi okuvala ama-circuit breaker, kunezinketho ezimbalwa ezitholakalayo.Olunye uhlobo oludumile i-circuit breaker lockout, eklanyelwe ngokuqondile ukungena phezu kokuguqula noma ukushintshwa kwe-breaker circuit ukuze kuvinjwe ukuthi ingavulwa.Lawa madivayisi wokukhiya atholakala ngebanga losayizi ukuze athwale izinhlobo ezahlukene zama-circuit breaker futhi avame ukuhlonyiswa nge-hasp noma i-clamp ukuze avikeleke endaweni.
Olunye uhloboidivayisi yokuvala ama-circuit breakerumaka wokuvala i-circuit breaker.Lolu cingo aluvimbeli ngokomzimba kuphela isiphazamisi sesifunda ukuthi sisebenze kodwa futhi luhlinzeka ngenkomba ebonakalayo yesimo semishini.Ithegi inganamathiselwa kudivayisi yokukhiya ukuze kuboniswe ulwazi olubalulekile, njengesizathu sokuvala ngaphandle, igama lezisebenzi ezigunyaziwe, nosuku nesikhathi sokuvala ngaphandle.
Ngaphezu kweizingidi ze-loto kanye namadivayisi wokukhiya ama-breaker circuit, kukhona ezinye izinhlobo zemishini yokukhiya eyakhelwe okokusebenza nemishini ethile.Isibonelo, ama-haps e-lockout asetshenziselwa ukukhiya ngokuphephile imithombo yamandla eminingi ngedivayisi eyodwa, okuyenza ifaneleke ezimweni zokukhiya iqembu.Khonamanjalo, izinto zokuvala ama-valve ebhola aklanyelwe ukuthi alingane phezu kwesibambo se-valve yebhola ukuze avinjwe ukuthi singaphenduki, futhi amathuluzi okuvala ikhebula asetshenziselwa ukukhiya impahla emikhulu nenomumo ongajwayelekile.
Lapho ukhetha aidivayisi yokukhiya, kubalulekile ukucabangela izidingo ezithile zemishini noma imishini ekhiyelwa ngaphandle.Izinto ezifana nohlobo lomthombo wamandla, usayizi nokuma kwemishini, kanye nezimo zemvelo kufanele zonke zibhekwe.Ukwengeza, kubalulekile ukuqinisekisa ukuthi izisetshenziswa zokukhiya zithobela izindinganiso zokuphepha ezifanele nemithetho ukuze kuqinisekiswe ukusebenza kwazo.
Sengiphetha, izingidi ze-loto kanyeamadivaysi okuvala ama-circuit breakerziyizibonelo ezimbili nje zezinhlobo ezahlukene zamadivayisi wokukhiya atholakalayo.Ngokukhetha idivayisi efanelekile yokuvala ngaphandle yohlelo lokusebenza olunikeziwe, abasebenzi bangazivikela ngempumelelo emithonjeni yamandla eyingozi futhi bavimbele izingozi endaweni yokusebenza.Kubalulekile kubaqashi nabasebenzi bezokuphepha ukuthi banikeze ukuqeqeshwa okufanele kanye nesiqondiso ekukhethweni nasekusetshenzisweni kwemishini yokuvala ukuze kuqinisekiswe ukuphepha kwabo bonke abasebenzi abathintekayo emisebenzini yokulungisa nokulungisa.
