Iphutha lomhlabathi lingaba yingozi enkulu uma lingalungiswa ngokushesha. NgeReactance Ground System, kunengxenye eyengeziwe phakathi kokungathathi hlangothi nomhlaba ukukhawulela inani likagesi ogeleza ngalo uma kwenzeka kuqhuma ipayipi noma enye into evuza amanzi noma ichithe kuyo. Kepha lokhu akuhlali kuvikela ngokwanele kuwo wonke umuntu; ngakho-ke kwesinye isikhathi amadivayisi amaningi ayadingeka ukuvimbela noma yimuphi umonakalo ongenzeki njenge-Transient Voltage Surge Suppressors (TVSS) ecindezela ukuqhuma ngamandla ngokuvala amandla amaningi ngokweqile ngaphambi kokuba afinyelele kumishini ebucayi njengamakhompyutha axhumeke ezitolo asondele lapho amandla kagesi enzeka ngesikhathi seziphepho ngenxa ukushaya kombani eduze kwalapho uhlala khona!
Uyini umehluko phakathi kwe-reactance ne-resonant grounding system?
Ukwenza phansi kukhawulela okukhona manje ukuze kugcinwe kuphephile futhi kungaphakathi kwebanga elamukelekayo. Lokhu akufani nokugxila okusebenzayo noma okuqinile okungaholela emisinga engaphandle kwemingcele yokuphepha, kepha ayinciphisi imisinga yamaphutha omhlaba njengoba nje isisekelo se-resonant sizokwazi ukwenza kanjalo.
Ukuphinda usebenzise isisekelo uhlobo lokuvikelwa kwephutha lomhlabathi. Ilele phakathi kokusekelwa okusebenzayo noma okuqinile nezindawo zomhlaba ezinamakhemikhali, okubiza kakhulu ukufaka kepha kunezingozi eziphansi ngoba zingakwazi ukusingatha imisinga ephakeme ngaphambi kokukhubeka ngenhloso yokuphepha. Lapho ixhunywe ochungechungeni namanye amasistimu (njengohlelo lukagesi) kuyasiza ukugcina okwamanje kungaphakathi kwemikhawulo ephephile ngokusebenzisa ukuphendula lapho kunokumelana okuningi kakhulu kulayini wokuphakelwa kwamandla - lokhu kwenzeka kaningi phakathi kwama-surges lapho ama-voltage spikes aholela ekumelaneni okuphezulu izimo okufanele zilungiswe ngokushesha hleze kube nobungozi ekulimaleni okokushisa okweqile okufana namasekethe wekhompyutha noma ama-motors asebenza ngokugcwele ngaphansi komthwalo oweqile. Amaphutha asezingeni ancishisiwe kepha abeka ingozi ethile; Ubulukhuni babo buxhomeke kakhulu ekutheni amaphutha womhlaba anamandla akhona yini.
Uyini umehluko phakathi kokumelana nezisekelo nokumelana ne-earthing?
Umehluko phakathi kohlelo lokuvikela ukumelana nokwemba umhlaba, ukuthi owokuqala uhlinzeka ngokuvikelwa ezimeni ezingalingani ngokuthwala insalela yamanje uma kwenzeka amaphutha edlulela phansi. I-Earthing ngakolunye uhlangothi ingenziwa ngaphakathi kwemishini kagesi ngezinjongo zokuzihlukanisa noma njengengxenye yecebo lokuvimbela ubungozi.
Isisekelo, ukugxusha umhlaba nokumelana nakho konke kungamagama abonakala esetshenziswa ngokungafani lapho kukhulunywa ngogesi. Kodwa-ke, ngayinye inezinhloso zayo eziqondile zohlelo lukagesi lwesakhiwo noma lokwenza izinto zokusebenza kanye nezinzuzo ekwehliseni ukuphazanyiswa komsindo ngezinto ezifana namathelevishini. Isibonelo, ngenkathi zombili zibandakanya ukuxhumanisa into namandla omhlaba komunye umqhubi ogxilile noma ngenhloso ngokuxhumana noma ngokungahlosi ngokusebenzisa ukuvuza kwamanje; eyodwa iqinisekisa ukuphepha lapho kunephutha khona ngokunikeza ukuvikeleka ekushayweni ugesi ngenkathi enye inikeza ibhalansi yomhlaba eyehlisa ukuhlanekezela okubangelwa ukushintshana kwemisinga egeleza phakathi kwemithwalo emibili engalingani (yize inganciphisi i-current current).
Futhi funda: le yindlela ogcina ngayo umnyango wakho wegaraji uthanjisiwe ngaso sonke isikhathi
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
