Kubaluleke ngani ukuvikela ama-over-voltage kanye nama-under-voltage?
Ngolunye usuku, umphathi wemishini evela efektri eseduze wagijimela emnyangweni wethu wezobuchwepheshe, ejuluka kakhulu futhi ekhuluma ngezwi lokukhathazeka. Ifektri yakhe yezingxenye ze-elekthronikhi yayilungiswa ngegridi kagesi ngalolo suku lapho i-voltage ikhuphuka ngokuzumayo yaya ku-380V. Ngaphandle kokufakwa kwezivikelo ze-over-voltage kanye ne-under-voltage, imigqa emithathu yokukhiqiza yema ngokushesha. Amabhodi e-motherboard amathuluzi emishini amaningana angenisiwe alimala ngqo, kanti ukulahlekelwa kokuqala kulinganiselwa ukuthi kudlula ama-yuan angu-200,000.
Njengoba sibhekene nokushintshashintsha okufanayo kwamandla kagesi, izivikeli ze-over-voltage kanye ne-under-voltage endaweni yethu yokusebenzela zakhubeka ngokunembile zingakapheli imizuzwana engu-0.1, zanqamula ukunikezwa kwamandla kagesi okungavamile ngesikhathi esifanele futhi zashiya yonke imishini ingashintshi. Uma amandla kagesi esezinzile, izivikeli ziqala kabusha ngokuzenzakalelayo, okuvumela imigqa yokukhiqiza ukuthi iqale kabusha kalula ngaphandle kwesikhathi sokungasebenzi.
Yiziphi izici ezenza imisebenzi kanye nokuvikelwa kwabavikeli be-over-voltage kanye ne-under-voltage?
Ukushintshashintsha kwamandla kagesi kugridi yamandla kuvame kakhulu kunalokho esingakucabanga. Amahora okusetshenziswa kwamandla aphezulu, izifunda zokuguga, ukulungiswa okuphuthumayo, ngisho nezimvula ezinkulu kungabangela izinkinga zama-voltage aphezulu noma angaphansi kwamandla kagesi. Ama-voltage angaphansi kwamandla kagesi aphoqelela imishini eqhutshwa yinjini ukuthi isebenze ngaphansi kwezimo zokulayisha ngokweqile, okubangela ukuthi ama-coil ashise kakhulu futhi ashise. Ama-voltage aphezulu, ngakolunye uhlangothi, alimaza ngqo izingxenye zikagesi, okuholela ekuhlulekeni okungenakuguqulwa. Emafektri, ezindaweni zezentengiselwano, kanye nezakhiwo zamahhovisi, i-anomaly eyodwa yama-voltage ayigcini nje ngokubangela izindleko zokulungisa imishini, kodwa futhi ibangela ukulahlekelwa okukhulu njengokumiswa kokukhiqiza, ukubambezeleka kwama-oda, kanye nokonakala kwempahla.
Isivikelo esisebenza ngamandla aphezulu kanye nangaphansi kwamandla kagesi sisebenza njengomlindi wokuphepha ohlakaniphile wezifunda zikagesi. Siqapha amazinga kagesi amahora angu-24 ngosuku, izinsuku eziyi-7 ngesonto ngesikhathi sangempela. Lapho sibona amandla kagesi angaphezu komkhawulo ophephile, sinqamula amandla kagesi ngaphakathi kwama-millisecond, sisuse izingozi ezihlobene namandla kagesi emthonjeni. Lapho amandla kagesi ebuyela kumapharamitha ajwayelekile, singasetha kabusha ngokuzenzakalelayo noma ngesandla, siqinisekise ukuthi amandla kagesi awaphazamiseki. Ngokungafani nama-fuse endabuko kanye nokushintsha komoya, sigxile ekulweni "nosongo olungabonakali" lwezinkinga ze-voltage, sigcwalise izikhala kumadivayisi okuvikela avamile futhi sifinyelele ngempela ekuvimbeleni ngaphambi kokuba kwenzeke izehlakalo.
Imikhiqizo yethu ivelele njengokukhetha okuthandwayo kwamabhizinisi amaningi, isekelwa yizinzuzo ezintathu eziyinhloko:
1.Ukuqapha Okunembile: Inikeza ukunemba kokutholwa kwamandla kagesi okungu-±1V kanye nesivinini sokuphendula samasekhondi angu-0.1, ibamba ngisho nokungahambi kahle kwamandla kagesi amancane ngaphandle kokwehluleka.
2.Kuhlala isikhathi eside futhi kuphephile: Iqukethe i-casing evimbela ilangabi kanye nomklamo wokuvikela ukukhuphuka, imikhiqizo yethu inesitifiketi sikazwelonke se-3C, iqinisekisa ukusebenza okuthembekile ezindaweni zamandla eziyinkimbinkimbi kanye nokuphila isikhathi eside kwenkonzo.
3.Ukuhambisana Okungenziwa Ngokwezifiso: Kutholakala ngochungechunge oluthathu lwezinhlelo zokusebenza zasekhaya, zezentengiselwano, nezezimboni, sinikeza ukwenza ngokwezifiso amapharamitha ukuze kuhlangatshezwane nezidingo zokuvikela kuzo zonke izimo ezahlukahlukene.
Ngokufigqiwe
Ukuphepha kukagesi akuvumeli thuba lenhlanhla. Isivikelo esincane esisebenza ngamandla aphezulu kanye nangaphansi kwamandla kagesi sidinga ukutshalwa kwezimali okuncane, kodwa sivikela umzila wakho wokukhiqiza kanye nokuphepha kwempahla ngempumelelo.
KhethaABANTU, futhi uvumele ukuvikelwa kochwepheshe kuvikele ugesi wakho ngokuthula kwengqondo.
