Ukusetshenziswa kwamandla aphezulu kubalulekile ezimbonini ezahlukahlukene njengokukhiqiza ugesi, ukukhiqiza, kanye nokuxhumana ngocingo. Amasokhethi ekhebula ane-voltage ephezulu (HV) angenye yezingxenye ezibalulekile kulezi zinhlelo zokusebenza. Lawa masokhethi aklanyelwe ukuxhuma izintambo ezine-voltage ephezulu ngokuphephile nangokuphumelelayo, kodwa futhi abeka izingozi ezinkulu uma engaphathwanga kahle. Lesi sihloko sichaza amathiphu abalulekile okuphepha okuphatha amasokhethi ekhebula ane-voltage ephezulu ukuqinisekisa ukuphepha kwabasebenzi kanye nemishini.
1. Qonda imishini
Ngaphambi kokusebenza neamasokhethi ekhebula ane-voltage ephezulu, qiniseka ukuthi uyiqonda kahle imishini ehilelekile. Yazi kahle imininingwane, izilinganiso, kanye nezinqubo zokusebenza kwezintambo nama-socket ane-voltage ephezulu. Lolu lwazi luzokusiza ukuthi ubone izingozi ezingaba khona futhi uqonde izinyathelo zokuphepha ezidingekayo okufanele uzithathe.
2. Ukusetshenziswa Kwezinto Zokuzivikela Zomuntu Siqu (i-PPE)
Gqoka njalo imishini yokuzivikela yomuntu siqu (i-PPE) efanele uma usebenza ngezisekelo zekhebula ezinamandla aphezulu. Lokhu kuhlanganisa amagilavu, izibuko, isigqoko esiqinile, kanye nezingubo ezivimbela ilangabi. I-PPE efanele inganciphisa kakhulu ingozi yokushaqeka kukagesi kanye nokunye ukulimala okuhlobene nokusebenza ngamandla aphezulu.
3. Uhlelo lokucima ugesi
Ngaphambi kokuxhuma noma ukunqamula noma yiziphi izimbobo zekhebula ezinamandla aphezulu, qiniseka ukuthi uhlelo alusebenzi. Lokhu kusho ukuvala ugesi bese usebenzisa imishini yokuhlola efanele ukuqinisekisa ukuthi isekethe ayisebenzi. Ungalokothi ucabange ukuthi isekethe ayisebenzi; sebenzisa njalo umhloli we-voltage othembekile ukuqinisekisa lokhu.
4. Gcina ibanga eliphephile
Ukugcina ibanga eliphephile kubalulekile lapho usebenza ngemishini enamandla aphezulu. Amandla aphezulu adala amasimu kagesi adlula ububanzi bezingxenye ezibonakalayo. Ngesikhathi sokusebenza, qiniseka ukuthi wena nanoma yibaphi abantu ababukele nigcina ibanga eliphephile kusuka ezingosini zekhebula ezinamandla aphezulu. Landela imihlahlandlela yokuphepha emisiwe ukuze ugcine ibanga elincane lokusondela futhi ugweme ukuthintana ngengozi.
5. Hlola imishini yakho njalo
Ukuhlolwa njalo kwezisekelo zekhebula ezinamandla aphezulu kanye nemishini ehlobene nakho kubalulekile ukuqinisekisa ukuphepha. Hlola izimpawu zokuguguleka, umonakalo noma ukugqwala okungase kuthinte ubuqotho besokhethi. Noma yiziphi izingxenye ezonakele kufanele zishintshwe ngokushesha futhi imishini kufanele isuswe ekusetshenzisweni kuze kube yilapho ukulungiswa sekuqediwe.
6. Landela izinqubo zokukhiya/zokuthega
Uma usebenza ezingosini zekhebula ezinamandla aphezulu noma eduze kwazo, inqubo yokukhiya/ukuthega (i-LOTO) kumele ilandelwe. Le nqubo iqinisekisa ukuthi imishini ivaliwe kahle futhi ayikwazi ukuvuselelwa ngengozi ngesikhathi sokulungiswa noma ukulungiswa. Landela njalo izinqubo ze-LOTO zenhlangano yakho ukuze uthole ukuphepha okwengeziwe.
7. Sebenzisa amathuluzi namasu afanele
Uma uphatha amasokhethi ekhebula ane-voltage ephezulu, sebenzisa amathuluzi aklanyelwe ukusetshenziswa kwe-voltage ephezulu. Amathuluzi ane-insulation asiza ukuvimbela ukuthintana ngengozi nezingxenye eziphilayo. Futhi, landela amasu afanele okuxhumanisa ikhebula kanye nokunqamula ukuze unciphise ingozi yokugoba noma ukujikeleza okufushane.
8. Ukuqeqesha nokufundisa abasebenzi
Ukuqeqeshwa kuyisici esibalulekile sokuphepha ekusetshenzisweni kwamandla kagesi aphezulu. Qiniseka ukuthi bonke abasebenzi ababandakanyeka ekusebenzeni kweziteshi zekhebula ezinamandla aphezulu baqeqeshwe ngokugcwele ngezinqubo zokuphepha, ukusebenza kwemishini, kanye nezinqubo zokuphendula eziphuthumayo. Izifundo zokuvuselela njalo zingasiza ekuqinisekiseni imikhuba yokusebenza ephephile.
Ekuphetheni
Ukusebenza neamajekhi ekhebula ane-voltage ephezuluekusetshenzisweni kwamandla kagesi aphezulu kudinga ukuqonda okujulile kwezinqubo zokuphepha kanye nemikhuba emihle kakhulu. Ngokulandela lawa macebiso okuphepha, abasebenzi banganciphisa kakhulu izingozi zomsebenzi we-voltage ephezulu. Ukubeka ukuphepha kuqala akuvikeli nje kuphela ukuphepha komuntu siqu, kodwa futhi kuqinisekisa ukuthembeka nokusebenza kahle kwezinhlelo ze-voltage ephezulu. Khumbula njalo ukuthi ukuphepha kuwumthwalo wemfanelo ohlanganyelwe futhi kubalulekile ukuhlala uqaphile ezindaweni ze-voltage ephezulu.
