Ngena elabhorethri yethu, ngena ngaphakathi kwezibani zethu, wazi okwengeziwe, unesithakazelo esikhulu, uthanda kakhulu, yilokho okushiwo yibhrendi, ubuhle bomkhiqizo.
Ukuhlola ukuthi ukumelana komhlabathi kuyahlangabezana yini nezidingo zendinganiso futhi kuthembisa ukuphepha kwezibani kubantu.
Umsebenzi wokufaka isisekelo ukuthi lapho ukufudumala kwezibani kungasebenzi, ugesi ovuzayo uzongena ngqo emhlabeni ngentambo yomhlabathi futhi ngeke ulimaze umzimba womuntu. Ngakho-ke, ukumelana okuncane kokufaka isisekelo, kuphephile kakhulu.
Ungakuhlola kanjani ukumelana komhlabathi?
Sihlola ngaphansi kwezindinganiso zaseYurophu:i-input current engu-12A, isikhathi sokuhlola imizuzwana emi-5, uma ukumelana komhlabathi ≦ 500m, kuyafaneleka.
Masisebenzise isiqeshana esibomvu ukuxhuma ucingo oluphansi.
Isiqeshana esimnyama sixhumanisa umzimba wesibani esithola ugesi kalula, sivame ukukhetha isikulufu.
Bese uqala ukuhlola.
Manje, ake sihlole inani lokumelana komhlabathi elingu-23MΩ kuphela, ngokuqinisekile liphephile ngokuphelele.
Kunamaphuzu amathathu abalulekile ekumelaneni:
1. Izinto zocingo lwangaphandle, ucingo lwethusi, olune-conductivity eqinile kanye nokumelana okuphansi
2. Ingxenye enqamulayo yentambo, lapho inkulu, incipha, ngokwezinga le-IEC, ingxenye enqamulayo yentambo idinga ≥ 0.75 square millimeter，sihlangabezana ngokuphelele nezindinganiso futhi siphakeme kunemakethe.
3. Ibhodi le-chip, kunengxenye exhumanisa ucingo olusemhlabathini, okumele iqinise isikulufu, noma izolahlekelwa ukuhanjiswa kwamandla.
Ngiyabonga ngokufunda lesi sihloko, singabakhiqizi bezibani ze-LED, asigcini nje ngokwenza umhlaba wonge amandla kakhulu, kodwa futhi sigcina uphephile.
Sizobonana ngesikhathi esizayo.
