Ukuzazi Okubalulekile Ngezisele Zelethi: Isilimi, Umsebenzi, Nobuchwepheshe Bokuhlanganisa

Yini Okuchaza Isisele Esinye SikaLeThi? Isibonelo, Umsebenzi Wokugcina Ngokwesikhundla, Nebizinesi Zokuhlanganisa

Isilayi esihlukene sisebenzisa isilayi noma izilayi ezisemthwakathini njengesibhakabhaka sakho—sizwa ngokuthi kuyasebenza kakhulu ekusenqoleni, okunika umkhondo wokugcina owodwa ngokuphelele uma kusetyenziswa. Lokhu kukhomba ukuthi kufakwe kahle, okunika ubuchwepheshe obubonakala ngokushesha: ukuzama ukususa kwenza ukuguqulwa kwesilinganiso, okwenza ukuthi ukungabonakali kahle. ISO/PAS 17712:2023 isibhalise lokhu, isibhekise amaphuzu okudesigna okungavunyelwa ukusebenzisa kabusha noma ukuthi kuthintwe ngaphandle kokubonakala. Nangona izilayi ezingenasilayi ziyagcina kakhulu, izilayi zesilayi zezinhlobo zezintsha zisaba izinkimbinkimbi zokusebenza lapho ukuthi kuzoba nokuthi kuzobonakala ngokushesha, ukuthi kuzoba nokuthi kuzoba nomthelela wokusebenza, nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nokuthi kuzoba nok......

Isimo sokubhekisana nesifunda: Lapha izilayi zesilayi zisivunyelwe kakhulu noma zisithintwa (EU RoHS, UK, US EPA, ISO/PAS 17712)

Amashele okuqondwa kwe-lead ayabhekana nezimboni zokuphatha ngokukhawuleza—kungakhathaliseki nge-UE RoHS Directive, imithetho yezinhlanhla zaseNingizimu Afrika, kanye ne-USA EPA’s Toxic Substances Control Act—lapho konke kubhekiswe ukuthi amashele okuqondwa kwe-lead akwazi ukufakwa emithethweni yezinto ezihlawulwa ngabantu kanye nezinto zokusebenza. Kepha, izivumelwano ezithile zikwamela ukuthi kuzosha kwezindawo zokugcina kwezindawo zokusebenza zeminyaka eyadlula futhi kwezindlela zokusebenza apho akukho isikhundla sokushintsha esifanayo ngokwesayensi esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha esinokuthi sibone isikhundla sokushintsha......

Amashele okuqondwa kwe-lead kuma-Meter wezinhlanhla: Ukubhekana nokuthi kufanele kubonakale ukuthi kwenziwe izinto ezithile, ukuthi kufanele kubhekiswe imithetho, kanye nokuthi kufanele kubhekiswe izinkinga zokusebenza kwezindawo zokuphatha ngokukhawuleza

Izindlela zokubhekana okuphambili: Ukuguqulwa kungathathiwa kabusha, ukubonakala kokuthi kwenziwe izinto ezithile, kanye nokuthi kufanele kubhekiswe ama-Meter ase-Automatic Meter Reading (AMI) noma amashele okuqondwa kwe-lead akwazi ukusebenza ngokuphelele

Kukusebenzisa ukubala kwezimali, ishili esikhanyayo kufanele siboneke ngokungathinti kusukela ekugcineni—kubhekisa ukuthi ukuthintela kuyabeka ubuchwepheshe obungafanani noma obuphawula ngokuvamile emhlabeni ngaphandle kokuthi kufuneka kususwakale ishili. Izinkumbu zokubona—njengokuthinteka kwesikhumba sesishili, ukuthinteka kwesihloko, noma ukuthinteka kwemilayezo yokuqinisa—kuyizindaba zokubhekisa phambili konke okungasithinti ngokungafanele. Njengoba izihlangu zisiza ku-Advanced Metering Infrastructure (AMI), izishili kufanele zibe ngekhaya ngokuphelele nezikhumba zokubona, izihlangu zokushaya izinkumbu, nezimboni zokuxhumana. Izishili zaselead nezishili zokuhlukanisa izinhlobo zaselead zisetha izindlela zokuthinteka ngokuphelele (ngokujwayelekile 25–45 N) nezindlela zokubeka ngokuphelele ukuze zingavikhi kusukela kuzinye izinto futhi zivumise ukubonwa kahle ngabasebenzi. Lokhu kukubhekisa kwezinto eziningi—ukuthinteka kwezinto ngokuphelele ngaphandle kokuthinteka kwezinhlobo zokusebenza—kuyakunzima ukuthi kungabhalwe ngokuphelele kuma-program ye-smart meter.

Ukubuyekeza Kwempilo: Izishili zokuhlukanisa izinhlobo zaselead nezishili zokuhlukanisa izinhlobo zaselead ezingenakho i-lead kwezishili zama-smart meter (isb. i-UK National Grid, 2021–2023)

Amasayensi aya kusukela kuzo kwezinye izinhlangano zokusebenza ngokwesibonelo kubhekisele ku-lead-composite ne-lead-free alloy seals ukuze zihambisane nezimfuneko zokulinda umhlaba ngaphandle kokuthi zithintele isikhungo. Phakathi kwe-2021 ne-2023, i-UK National Grid yasetha izikhumba eziningi kakhulu (ezingaphezu kwe-12) ze-composite-based seals kwezinkampani zayo zokubala okusheshayo. Zaveliswa ukuze zihambisane nokufana nokugcina ukuguqula okungavunyelwa phansi kwe-lead esheshayo, lezi seals zizama ukunciphisa ukuguqula kwe-lead nge-95% ngaphansi kwe-RoHS futhi zilindile ukuguqula kwesikhathi, ukubonwa kwe-UV, nokudlula kwezinhlobo zokudlula okuhambisana nezinkampani zokubala ezingaphandle kwendawo. Ukuchaza kwezindawo kubonisa ukuthi akukho kuthinta okuphakeme kakhulu kwezinkampani zokuthintela ngokungafanele ngaphansi kwe-legacy lead seals—kubonisa ukuthi ukufana kwezinkampani kungasekelwa. Lezi zisetha kubonisa indlela eyodwa yezinhlobo zokusebenza zokusha ziyahlinza ubukhulu bokubhala, ukuvikela ukuthintela, nokuhambisana kwe-AMI ngokufanayo.
