Ngaphandle kwawo, ubuchwepheshe obulula esibuthatha kalula bungaphela nje. Ukutadisha izinhlobo zamasekhethi kubalulekile hhayi kuphela konjiniyela kodwa nakumabhizinisi afuna izixazululo ze-elekthronikhi ezinokwethenjelwa neziphumelelayo. Ukuqonda ukuthi ukuhlelwa okuhlukile njenge-parallel circuit ne-series circuit kuthinta kanjani ukusebenza, ukuphepha, nezindleko kungahola izinqumo zokuthenga ezingcono. Noma ngabe wenza uhlelo lokukhanyisa lwekhaya noma inethiwekhi yokuzenzakalela enkulu, ukuqonda le miqondo yisinyathelo sokuqala esibalulekile. Lesi sihloko sizokuhambisa ezimisweni eziyisisekelo nasekusetshenzisweni okungokoqobo kwamasekhethi, kugcizelelwe nokuthi i-Shenzhen Huachuan Hi-Tech Electronics ingahlinzeka kanjani ngezingxenye ezisezingeni eliphezulu ozidingayo. Ekugcineni, uzoba nesisekelo esiqinile sokuxoxa ngezinhlobo zamasekhethi ngokuzethemba nobuchwepheshe.

Ngaphambi kokungena ezinhlotsheni eziqondile zamasekhethi, kubalulekile ukuqonda ukuthi iyini ngempela isekhethi kagesi nokuthi isebenza kanjani. Isekhethi kagesi iyiluphu evaliwe evumela ukuthi ugesi ageleze usuka emthonjeni wamandla udlule ezingxenyeni ezahlukene abuye emuva. Isekhethi ithathwa njengevaliwe lapho umzila ungaqamuki futhi ugesi ungageleza ngokukhululeka, kuyilapho isekhethi evulekile yenzeka lapho kunokuphazamiseka emzileni, okumisa ugesi ngokuphelele. Yonke isekhethi esebenzayo inezinto ezine eziyisisekelo: umthombo wamandla njengebhethri noma i-generator, izinto eziqhuba ugesi njengezintambo zethusi, umthwalo osebenzisa ugesi (isib., isibani noma i-motor), kanye nengxenye yokulawula njengeswishi. Iqhaza lengxenye ngayinye libalulekile ngoba noma ukungahambisani okuncane kungadala ukungasebenzi kahle noma ukwehluleka. Isibonelo, ukusebenzisa izintambo ezingancane kakhulu ohlelweni oluphethe amandla amakhulu kwandisa ukumelana nokugeleza kukagesi futhi kukhiqize ukushisa okuyingozi. Lezi zisekelo ziyisisekelo sazo zonke izingxoxo eziphathelene namasekhethi alandelanayo, ahambisanayo, kanye nezinhlanganisela ezilandelayo. Ukuzazi kahle kuyisihluthulelo sokuklama izinhlelo ezinokwethenjelwa kunoma yimuphi umkhakha.

Omunye umqondo obalulekile umehluko phakathi komsinga oqondile (DC) nomsinga oshintshanayo (AC), njengoba lokhu kunquma ukuthi izingxenye zisebenzisana kanjani ngaphakathi kwesekethe. Kumasekethe e-DC, ama-electron ageleza ngendlela eyodwa, okwenza kube yinto ekahle yemishini esebenza ngebhethri kanye nezinhlobo eziningi zamasekethe anengqondo ezinhlelweni zekhompyutha. Kumasekethe e-AC, indlela yokugeleza iyashintsha ngezikhathi ezithile, okuyindlela ejwayelekile yamandla asendlini ngoba ingadluliswa emabangeni amade ngempumelelo. Ukukhetha phakathi kwe-AC ne-DC kuthinta konke kusukela emazingeni kagesi kuya ekwakhiweni kwemishini yokuvikela njengama-vacuum circuit breaker. Ukwengeza, ubuchwepheshe besimanje buvame ukudinga ukuguqula phakathi kwalokhu okubili, okuletha indima ye-full wave rectifier. Lokhu kuqonda kwezincazelo eziyisisekelo nezingxenye kukulungiselela ukuhlola izindlela ezahlukene zokuhlela amasekethe. Futhi kubeka isisekelo sokwazisa izixazululo ezithuthukisiwe ezinikezwa abaholi bezimboni abafana ne-Huachuan Hi-Tech.

Uhlelo olulula kakhulu yisifunda esinomzila owodwa lapho zonke izingxenye zixhunywa ngokulandelana, okwaziwa ngokuthi isifunda esilula noma isifunda esixhunywe ngokulandelana (series circuit). Ekuhlelweni kwe-series, umsinga udlula kumthwalo ngamunye ngokulandelana, okusho ukuthi umsinga ofanayo ugeleza kuyo yonke ingxenye. Lo mklamo unezici ezihlukile: ukumelana okuphelele kulingana nesamba sokumelana ngakunye, futhi i-voltage kumthwalo ngamunye ihlanganisa ukuze ifinyelele ku-voltage yomthombo. Ububi obukhulu ukuthi uma ingxenye eyodwa yehluleka, isifunda sonke siyaphuka, futhi wonke amadivayisi ayeka ukusebenza. Yingakho izifunda ze-series zingavamile ukusetshenziselwa ukusabalalisa amandla emakhaya noma ezimbonini; zivame kakhulu ezinhlelweni ezinjengezibani ezinamacwecwe noma izinzwa ezilula. Nokho, ukuqonda umehluko phakathi kwesifunda esihambisanayo (parallel circuit) nesifunda esixhunywe ngokulandelana (series circuit) kubalulekile ngoba kuthinta ngqo ukuthembeka nezindleko zokulungisa. Emabhizinisini, ukukhetha ukuhlela okungalungile kungaholela ekwehleni okuvamile kanye nezindleko eziphakeme.

Ngokuphambene, isekethe elihambisanayo lihlukanisa umsinga ube yimiganga eminingi, ngamunye unikeza umthwalo ohlukile ngokuzimela. Lokhu kusho ukuthi ingxenye ngayinye ithola amandla aphelele omthombo, futhi umsinga ophelele uyisamba semisinga emgagweni ngamunye. Inzuzo enkulu ukuzimela: uma omunye umganga wehluleka, eminye iyaqhubeka isebenza ngokujwayelekile, okwenza amasekethe ahambisanayo abe ngumgogodla wezinhlelo eziningi zezindlu nezimboni. Isibonelo, ukufakwa kocingo ngokuhambisanayo kuqinisekisa ukuthi ukuvala isibani esisodwa akuthinti ezinye egumbini elilodwa. Inkinga ukuthi amasekethe ahambisanayo ngokuvamile adinga izintambo eziningi futhi anokumelana okuphansi okuphelele, okwandisa ukudonsa komsinga ophelele. Aphinde afune izinyathelo zokuvikela eziqaphelayo, njengokusebenzisa ama-fuse afanele noma ama-vacuum circuit breaker emgagweni obalulekile. Uma uhlanganisa izinto zochungechunge nezihambisanayo kunethiwekhi efanayo, udala amasekethe ayinkimbinkimbi noma ahlanganisiwe. Lezi zinhlelo eziyingxubevange zivumela onjiniyela ukuthi bafeze izidingo eziqondile zamandla kagesi nomsinga kuyilapho begcina ukungafani okwengxenye. Isibonelo, ishaja yeselula yesimanje isebenzisa isekethe elihlanganisiwe kanye ne-full wave rectifier ukuze ilawule ukulethwa kwamandla. Ukwazi kahle zonke lezi zinhlobo zamasekethe kunika amandla ochwepheshe ukuthi bakhe izinhlelo eziphumelelayo futhi eziqinile.

Izakhiwo zokuhlanganisa zivame kakhulu ekusebenzeni kwezimboni ngokuzenzakalelayo nasekubalweni, lapho izinhlelo ezingaphansi ezahlukene zidinga izimo zikagesi ezenziwe ngokwezidingo. Ukuklama isekethe elinjalo kuhilela ukuhlaziya ubudlelwano phakathi kwengxenye ngayinye yochungechunge kanye nengxenye ehambisanayo ukuze kubalwe ukumelana okuphelele, ukwehla kwamandla kagesi, nokugeleza kwamanje. Onjiniyela bathembela kusofthiwe yokulingisa isekethe kanye nezimpawu zomdwebo ukuze babikezele ukuziphatha ngaphambi kokuhlanganiswa ngokomzimba. Ubunzima buyanda uma ufaka izinhlobo eziningi zesango elinengqondo ukuze ulawule izindlela zesignali kanye nezinqubo zokwenza izinqumo. Emabhizinisini ancike ekusebenzeni okungaguquki, ukutshala imali ezingxenyeni zekhwalithi ephezulu ezivela kumthengisi othembekile njengoIkhaya kungenza umehluko phakathi kohlelo olusebenzayo noluhluleka njalo. Ukuqonda lezi zinhlobonhlobo akusikho nje ukufunda; kunomthelela wangempela ekuphepheni, ekusebenzeni kahle, nasezindlekweni eziphansi.

Ukusebenza kwanoma yisiphi isekethe kulawulwa izinto ezintathu eziyisisekelo: i-voltage, i-current, kanye ne-resistance. I-voltage, elinganiswa ngama-volts, umehluko wamandla kagesi ophusha ama-electron ukuba ahambe ngomqhubi. I-current, elinganiswa ngama-amperes, isilinganiso sokugeleza kwalawo ma-electron. I-resistance, elinganiswa ngama-ohms, iphikisana nalokho kugeleza futhi iguqule amandla kagesi abe ukushisa. Lezi zinto ezintathu zixhunyaniswa nguMthetho ka-Ohm, othi i-voltage ilingana ne-current iphindwe nge-resistance (V = I × R). Lobu budlelwano obulula buvumela onjiniyela ukuthi babikezele ukuthi ukushintsha ipharamitha eyodwa kuthinta kanjani ezinye. Isibonelo, kusekethe yochungechunge, i-resistance ephelele iphezulu, ngakho i-current iphansi uma kunikezwe i-voltage ethile, kuyilapho kusekethe ehambisanayo, ukuncipha kwe-resistance kuholela ekudonseni okukhulu kwe-current. Ukuqonda lezi zimiso kubalulekile lapho ukhetha izingxenye kanye nemishini yokuvikela.

Imidwebo yezifunda isebenzisa izimpawu ezijwayelekile ukumela izingxenye ezinjengama-resistor, ama-capacitor, ama-diode, nama-switch. Ukwazi ukufunda nokudala le midwebo kuyikhono eliyisisekelo kunoma yimuphi uchwepheshe noma unjiniyela. Izimpawu zisiza ukubona ukuthi izifunda ezahlukene, kuhlanganise nalezo ezisebenzisa i-full wave rectifier noma izinhlobo ezahlukene ze-logic gate, zixhunywe kanjani nokuthi amasignali ahamba kanjani. Isibonelo, uphawu lwe-diode lukhombisa indlela yokugeleza kukagesi, okubalulekile ezifundeni ze-rectifier eziguqula i-AC ibe yi-DC. Ngaphezu kwalokho, izimpawu zama-breaker nama-fuse zibekwa lapho kudingeka khona ukuvikelwa, ngokuvamile zilandelelana nemithwalo ebalulekile. Uma usebenza nezinhlelo zamandla aphezulu, ukuqonda lezi zimpawu kusiza ukuqinisekisa ukufakwa okufanele.Products njengama-fuse ezimboni nezibambi zawo. Ukuqonda kahle lezi zimiso kunika amabhizinisi amandla okuxhumana ngokucacile izimfuneko futhi agweme amaphutha abizayo.

Imifelandelela kagesi ingumgogodla wazo zonke izimboni, inika amandla imisebenzi ebalulekile kusukela ekukhanyeni okulula kuya kumakhompyutha ayinkimbinkimbi. Ekukhanyeni kwezindlu nezohwebo, imifelandelela ehambisanayo iqinisekisa ukuthi isibani ngasinye sisebenza ngokuzimela, ukuze ukungasebenzi kwesibani esisodwa kungafinyezi igumbi lonke. Izinhlelo zokufudumeza njengeziko likagesi nezifudumezi zasendlini zivame ukusebenzisa izinto ezilandelanayo ukuze zilawule izinga lokushisa ngokunembile, njengoba ukwengeza ukumelana nokugeleza kukagesi kukhulisa ukukhishwa kokushisa. Emhlabeni wamakhompyutha, ama-motherboard asebenzisa imifelandelela ehlanganisiwe nezinhlobo eziningi zamasango anengqondo ukuze acubungule idatha ngejubane elikhanyayo, kuyilapho ama-power supply ehlanganisa i-full wave rectifier ukuze anikeze i-voltage ye-DC ezinzile. Izinhlelo zokuxhumana, ezihlanganisa imibhoshongo yamaselula namathambo e-fiber-optic, zincike ekuhlelweni okuhleliwe okuhambisanayo nokulandelanayo ukuze kugcinwe ubuqotho besignali emabangeni amade.

I-automation yezimboni ingomunye umkhakha lapho ulwazi lwezifunda zikagesi lubalulekile. Izimboni zisebenzisa izifunda eziyinkimbinkimbi ezihlanganisiwe ukuze zilawule ama-motor, izinzwa, kanye nezilawuli ezinengqondo ezihlelekayo (ama-PLC) ngokuthembeka okuphezulu. Ukusetshenziswa kwezinhlelo zokuvikela ezithuthukisiwe, okuhlanganisa ama-vacuum circuit breaker, kuqinisekisa ukuthi imishini ivikelekile ekugcwalisweni ngokweqile nasezifundeni ezimfushane ngaphandle kokuphazamisa ukukhiqiza ngokungadingekile. Emishinini yezokwelapha, njengemishini ye-MRI kanye nezihloli zeziguli, izifunda ezinembile kumele zisebenze ngaphandle kwephutha, ngokuvamile zinokuphindaphinda okwakhelwe ngaphakathi ngezindlela ezihambisanayo. Kuyo yonke le misebenzi, ikhwalithi yezingxenye ithinta ngqo ukusebenza nokuphepha. Yingakho onjiniyela bephendukela ku-Mayelana Nathi ukufunda indlela i-Shenzhen Huachuan Hi-Tech Electronics ehlinzeka ngayo ngezingxenye eziqinisekisiwe, ezihloliwe ezihlangabezana namazinga omhlaba. Ukukhetha uhlobo olufanele lwesekethe kanye nomhlinzeki ofanele ekugcineni kunquma impumelelo yanoma yimuphi umsebenzi.

Akukho ukuxoxwa ngezinhlobo zamasekhethi okuphelele ngaphandle kokukhuluma ngokuphepha nokunakekela, ngoba ukuklama okungafanele noma ukunganakwa kungaholela emililweni, ukulimala kwemishini, noma ukulimala komuntu. Ukuvimbela ukugcwala ngokweqile kuqala ngokukala kahle izintambo nezinto zokuvikela ngokusho kwamandla kagesi alindelekile. Emseketheni ohambisanayo, lapho amandla kagesi esewonke engaba makhulu, igatsha ngalinye kufanele libe ne-fuse yalo noma i-breaker ukuze lihlukanise amaphutha. Ukuvikelwa kwezifinyezo ezimfushane kubalulekile ngokufanayo: indlela engezansi enokumelana okuphansi kakhulu ingabangela ukugcwala kwamandla kagesi okukhulu, ngakho-ke izinto ezifana nama-vacuum circuit breaker ziklanyelwe ukuphazamisa ukugeleza ngemizuzwana. Izinto ze-Residual current (ama-RCD) zengeza ungqimba olunye ngokuthola ukungalingani phakathi kwezintambo eziphilayo nezingathathi hlangothi, zinqamule amandla uma kukhona ukuvuza. Izinhlelo zokufaka phansi zinikeza indlela ephephile yamandla kagesi amaphutha, zinciphise ubungozi bokushaqeka kukagesi.

Ukuhlola okuvamile kokulungisa kubalulekile ukuze kuqinisekiswe ukuthi amasekhethi ahlala ephephile ngokuhamba kwesikhathi. Ukuxhumana okungaxhunyiwe, izintambo ezigqwalile, noma ukulimala kwe-insulation kungafaka ukumelana okungalindelekile noma kudale ukushisa okuyingozi. Ochwepheshe kufanele bahlole izingxenye ezinjengama-breaker, ama-relay, nezintambo ngezikhathi ezithile, ikakhulukazi ezindaweni ezinzima. Ukuqonda umehluko phakathi kwe-parallel circuit ne-series circuit kusiza amaqembu okulungisa ukubikezela izindlela zokwehluleka: i-series string izocisha ngokuphelele uma kukhona iphutha elilodwa, kuyilapho i-parallel system ingase iqhubeke nokusebenza kodwa ibe nomthwalo owengeziwe emagatsheni asele.
