Ungakwenza kuphi ukuhlunga okusebenzayo kwe-harmonic kwenza umehluko omkhulu namuhla?

Ngichitha iningi leviki lami ligxile emafektri lisebenzisa ama-frequency frequency drives, Supplies angenakuphidlanga kanye nemishini yokushaja okusheshayo, ngakho-ke nginakekela okuncane ngama-buzzwords futhi ngaphezulu ngezixazululo eziku-monday ekuseni. Ngokuhamba kwesikhathi ngakhula ngithembele kubalingani abanjengoGeyaNgegiya eliphansi elinokwethenjelwa, futhi ngiqhubeka ngifinyelela iIsihlungi esisebenzayo se-harmonicLapho okufushane kulula kodwa kunesihluku. Gcina ukukhiqizwa phezulu, gcina inkohliso yokuzola, gcina amakhebuli apholile. Nansi indlela engisondela ngayo enkingeni nalokho engikufunde ensimini.

Kungani ulandelela, izintambo ezishisayo, futhi ama-transformers athambisayo avela lapho kukhiqizwa esikalini?

• Ngibona okungeyona i-sinusoidal yamanje kusuka kuma-VFS, ama-pulse-pulse pulse, i-UPSS, kanye namashaja asheshayo acindezela i-thdi kahle ngenhla kwezinombolo ezintofontofo.
• Abaqhubi abangathathi hlangothi bagijima bafudumele ngenxa yama-triplen Harmonics, ikakhulukazi ezinhlelweni ezintathu ezinama-wire-wire adding eyodwa-Phase-It.
• Amabhange eCapacitor ahoxiselwe yi-resonance asajeziswa ngamanje, afe kusenesikhathi.
• Izilungiselelo zokuvikelwa zibukeka zilungile ephepheni, kepha uhambo lokuncipha luphikelela ngenxa yamagagasi ahlanekezelwe kanye nezici ze-crest.

Yiziphi izinkinga engilindele ukuzihlunga okusebenzayo ukuxazulula emhlabeni wangempela?

• Donsela i-thdi phansi ibheke kwelitshe elivumelanisa nenqubomgomo yesayithi kanye nemikhawulo yokusebenzisa ngenkathi igcina i-thdv izinzile.
• Nikeza ukwesekwa kwamandla okusebenzayo okuguqukayo ukuze uhlanze isici samandla ngesikhathi sokulayisha okuguquguqukayo.
• Bulala ama-oda athile avumelanayo aphatha kabi ama-generator noma ama-transformers kuma-micrograry.
• Yabelana ngokulayisha kuwo wonke amakhabethe amaningi ngaphandle kokulinganisa okwenziwe ngesandla.

Nginquma kanjani phakathi kwe-ahf, isihlungi esingenakuqhathaniswa, isiphetho sangaphambili esisebenzayo, noma i-multi-pulse rexifier?

Ngiqala ngokuhlanganiswa kwemithwalo, ukuhlukahluka komjikelezo womsebenzi, kanye nendawo enginakho ebhodini. Ngigcina lokhu kuqhathanisa kusondele lapho ngixoxa nababambiqhaza.

Kufanele ngibeke kuphi i-AHF futhi ngigwema kanjani amaphutha e-CT?

• Ngibeka i-AHF eduze kwebhasi ngifuna ukulihlanza ukusika ukungcola phakathi kokuhlunga nokulayisha.
• Ngibeka i-CTS ebhasini elifanayo i-AHF inxephezelo futhi ngigcina ubumbano luhambisana nale ncwadi. I ilebula s1 ne-S2 ngesikhathi sokufaka, azikho amanqamukisi.
• Ngiqinisekisa ukujikeleza kwesigaba kanye nokuqondiswa kwesinxephezelo ngesivivinyo somthwalo ohleliwe ngaphambi kokuthi ngiphume endaweni.

Ngilibekela kanjani usayizi wekhabethe ngaphandle kokuphonsa imali ngezinombolo zamagama?

• Ngilinganisa i-RMS yangempela kanye ne-harmonic spectrum emaphoyinti abasebenzi ambalwa, hhayi nje isifinyezo semizuzu emihlanu.
• Ngilingana nenani le-vector lama-oda aqondisiwe kanye ne-headroom factor yokukhula nokushisa.
• Ngilapha ukwesekwa kwamandla okusebenzayo njengebhonasi, hhayi esikhundleni sokuthola imali efanelekile ye-KVA.

Ngabe iKhabhinethi elilodwa eliphakathi lingaphatha lonke ibhodi noma kufanele ngihambe?

Ngihlukanisa isinxephezelo lapho izintambo zinde futhi lapho isinyathelo esikhulu sisebenza kuma-feeders akude. I-Central isebenza kahle lapho i-Main Bus ihlinzekwa kakhulu imithwalo yendawo kanye nokubukeka okubukeka okufanayo. Kusatshalaliswa kukhanye nge-sprawl nakumasayithi anobuntu obuningi be-hamonic.

Kuthiwani ngamazinga nezidingo zomsebenzi engidinga ukudlula kuzo?

• Ngibhekisisa uphawu ngokulwa nemithetho yesayithi ekhombisa imikhawulo evamile ye-harmonic ye-PCC.
• Ngiqinisekisa ukuhambisana nokusebenza kwe-generator kumodi yesiqhingi yama-microgram.
• Ngibhala ngaphambi nangemva kwemiphumela nge-analyzer efanayo newindi lesikhathi ngakho-ke unjiniyela wokusebenzisa ubona ama-apula kuma-apula.

Yikuphi izingqinamba ezifihliwe amaphrojekthi anciphile ngaphezu kwesikhathi sokuhola kwe-Hardware?

• Umoya omncane nothuli. Ngifaka amazinga okushisa bese ngichaza izihlungi ezingabanjwa yizobuchwepheshe ngemizuzu.
• Ubuqotho. Ngiqinisekisa izihlangu zeBonding ne-Cable ngoba imisinga ejwayelekile yemvamisa idinga indlela yokubuya ehlanzekile.
• Ezokuxhumana. Nginquma ukuthi ngidalula idatha nge-modbus tcp, i-bacnet, noma isethi elula yokuxhumana eyomile yama-BMS Alarms.

Ngenza kanjani icala lebhizinisi ukuthi ezezimali zizokwamukela?

• Ngibala ukugwenywa isikhathi sokugwema kusuka kuhambo lwe-nuisance futhi ngishayele amaphutha.
• Ngingeza izinzuzo zokuphila empilweni ezibandayo ezipholile, impilo ye-capacitor ende, nomsindo we-transformer ophansi nokulahleka kwethusi.
• Ngifaka izinhlawulo zomsebenzi ezigwenyiwe kanye nokuncishiswa kwengozi ngesikhathi sokucwaningwa kwamabhuku.

Ngabe lubukeka kanjani uhlelo lokuqashwa oluhlanzekile ngaphandle kwedrama?

1. Capture eyisisekelo ngaphezulu kwewindi lokukhiqiza elimele.
2. Qinisekisa ukuqondiswa kwe-CT, ukujikeleza kwesigaba, kanye nemikhosi.
3. Nika amandla isinxephezelo ngezinyathelo ngenkathi ugawula ama-waveform.
4. Qinisekisa ukuqondiswa ngesikhathi somsebenzi osezingeni elibi kakhulu nezikrini zokuhlaziya izithombe zombiko.
5. Nikeza umhlahlandlela osheshayo wekhasi elilodwa lokusebenza nenqubo yokuhlola yekota.

Ngikwengeza kanjani umbono ongaphezulu kwamandla kagesi aphansi nasezindaweni ezinzima?

• KwaManzini kanye ne-OIL negesi ngithanda imiklamo ebiyelwe ngamabhodi ahlanganisiwe kanye nezilinganiso eziphakeme ze-ingress.
• Okomandla enzalo aphakathi ecabanga ukuthi izixazululo ezihlehlisiwe ezisebenzisa ama-LV affs kuma-feeder Second ukugwema ubunzima be-mv.
• Okomsindo we-IT I sebenzisa amakhabethe anamaphrofayili aphansi acoustic futhi agcine i-airflow ngaphambili kuya phezulu ukuze ilungele imithetho eshisayo ye-aisle nemithetho ebandayo.

Yini okufanele ngiyibuze umthengisi ngaphambi kokuba ngikhiphe i-po?

• Ngingabona imiphumela yesayithi efakiwe yephrofayili yokulayisha efana neyami
• Ngabe isebenzisa kanjani iKhabhinethi yokwabelana ngalo lapho ngifinyelela amayunithi afanayo
• Yini ijika lokuphothula le-thermal kanye nendlela yokubuyiselwa kwabalandeli
• Yimaphi ama-oda we-harmonic engingabeka phambili futhi wenza ngokushesha kanjani ukuthi izilungiselelo ziguquke ngaphansi komthwalo
• Ingabe iyunithi linganikeza ukuncishiswa kokubili okuvumelanayo nokusekelwa okusebenzayo okusebenzayo ngaphandle kwezingxabano

Ngingasebenzisa i-geya ahf nge-evgrade yami elandelayo yensundu

Yebo lapho isikhala sebhodi sifushane, umxube womthwalo ungcolile, futhi umgomo uhambisana ngokushesha nemininingwane ecacile. Ngiyathanda ukuthi ngingabeka iKhabhinethi eliseduze nebhasi lenkinga, isikali ngokufana, futhi ligcine izinketho zivulekile njengezinguquko zemishini ngokuhamba kwesikhathi.

Ngabe kufanele sikhulume ngesiza sakho namatshe okuhlosiwe

Uma ufuna ukubuyekezwa okusebenzayo kwe-spectrum yakho, usayizi, nokubekwa, ngiyajabula ukubheka imidwebo kanye neviki lezingodo. Uma uhlola umshayeli wendiza, finyelela futhi sikwazi ukumanga indlela ehlanzekile ukusuka ekulinganiseni ukuyobelwa. Xhumana nathiukuxoxa ngezilinganiso, ukulinganisa, kanye nezinyathelo zokukhokhisa.Thumela umbuzo wakhoFuthi ngizophendula ngesiphakamiso esihlelekile kanye nobubanzi obulindelekile bokuthuthuka kwesiza sakho.
