Indlela yokufaka isibambisi sokwanda kwamandla
1. Faka isibambisi sombani wamandla ngokuhambisana. Indawo yokufaka umshini wamalahle ingemuva lebhodi lokushintsha noma isishishi sommese (i-circuit breaker) ekilasini lendawo yokubuka yokufundisa ngesathelayithi. Sebenzisa amasethi amane okunweba kwepulasitiki ye-M8 kanye nezikulufu ezizithephayo. odongeni.
2. Usayizi wokufaka (70×180) kanye nezimbobo zokufaka ezihambisanayo kumshini wokubopha amandla kufanele kubhojwe odongeni.
3. Xhuma ugesi. Intambo ebukhoma yesibambi samandla ibomvu, intambo emaphakathi iluhlaza okwesibhakabhaka, futhi indawo ephambanayo ingu-BVR6mm2. I-Multi-strand copper wire, intambo yaphansi yomshini wamalahle iphuzi futhi iluhlaza, kanti indawo ephambanayo yi-BVR10m m2. Intambo yethusi eboshiwe, ubude bezintambo bungaphansi noma bulingana no-500mm. Uma umkhawulo ungaphansi noma ulingana no-500mm, unganwetshwa ngendlela efanele, kodwa isimiso sokugcina izintambo zibe mfushane ngangokunokwenzeka kufanele silandelwe, futhi ikhoneni kufanele libe ngaphezu kwama-degree angu-90 (i-arc kunokuba kwesokudla).
4. Xhuma ukunikezwa kwamandla kumqhubi wombani. Uhlangothi olulodwa lwekhebuli yesibambi samandla luboshwe ngokuqondile futhi ngokuqinile kutheminali yesibambi samandla. Intambo yaphansi ixhunywe kugridi yaphansi ezimele noma intambo yaphansi yokuphakelwa kukagesi enezigaba ezintathu ehlinzekwa yisikole.

Izinyathelo zokuphepha zokufakwa kwesibambisi sokwanda kwamandla
1. Isiqondiso sezintambo
Lapho isibambisi sombani sifakiwe, amatheminali okokufaka nokuphumayo akufanele axhunywe ngokuphambene, ngaphandle kwalokho, umphumela wokuvikela umbani uzothinteka kakhulu, futhi ngisho nokusebenza okuvamile kwemishini kuzothinteka. Ukuphela kokufaka kwesibambisi sombani kuhlobene nesiqondiso sokusakazeka kwegagasi lombani, okungukuthi, ukuphela kokufaka kwesiphakeli, futhi ukuphela kokuphumayo ukuvikela imishini.
2. Indlela yokuxhuma
Kunezinhlobo ezimbili zezindlela zezintambo: uxhumano lwechungechunge noxhumano oluhambisanayo. Ngokuvamile, kuphela indlela yokuxhumana yetheminali esetshenziswa ochungechungeni lokuxhuma indlela, kanti enye indlela yokuxhuma isetshenziswa ngendlela yokuxhuma ehambisanayo. Intambo engathathi hlangothi yekhebula lamandla ixhunywe embotsheni yezintambo ethi “N” ye-SPD yamandla, futhi ekugcineni intambo yaphansi edonswe embotsheni yezintambo “PE” ye-SPD yamandla ixhunywe kubha ephansi yokuvikela umbani noma ibha yaphansi yokuvikela umbani. Ukwengeza, indawo encane ye-cross-sectional yocingo oluxhumayo lwesibophi sombani kufanele ihambisane nezinhlinzeko ezifanele zephrojekthi kazwelonke yokuvikela umbani.

3. Uxhumano lwezintambo eziphansi
Ubude besisekelo socingo oluphansi kufanele bube bufushane ngangokunokwenzeka, umkhawulo owodwa kufanele uboshwe ngokuqondile endaweni yokugcina yesivimbi sombani, futhi ucingo oluphansi kufanele luxhunywe kunethiwekhi ezimele yokumisa phansi (engahlukanisiwe nesisekelo sikagesi) noma ixhunywe ocingweni oluphansi endaweni yamandla ezigaba ezintathu.
4. Indawo yokufaka
Isibambisi sombani esinikezwa amandla ngokuvamile sisebenzisa indlela yokuvikela esezingeni. Faka isisetshenziswa esiyinhloko sokuvikela umbani ekhabetheni elikhulu lokusabalalisa amandla ebhilidini. Okwesibili, faka idivayisi yokuvikela umbani wesibili endaweni yamandla angaphansi kwesakhiwo lapho izinto zikagesi zitholakala khona. Ngaphambi kwemishini ebalulekile ye-elekthronikhi, faka isibambisi sombani samandla esinezinga ezintathu, futhi ngesikhathi esifanayo, qinisekisa ukuthi azikho izinto ezivuthayo neziqhumane eduze nokufakwa ukuvimbela umlilo obangelwa izinhlansi zikagesi.
5. Ukucisha ukusebenza
Ngesikhathi sokufakwa, ukunikezwa kwamandla kufanele kunqanyulwe, futhi ukusebenza bukhoma kunqatshelwe ngokuphelele. Ngaphambi kokusebenza, i-multimeter kufanele isetshenziselwe ukuhlola ukuthi amabhasi noma amatheminali esigaba ngasinye acishiwe ngokuphelele yini.
6. Hlola izintambo
Hlola ukuthi izintambo zixhumene yini. Uma kukhona othintana naye, bhekana nakho ngokushesha ukuze ugweme ukuhamba kancane kwemishini. Ngemuva kokuthi ukufakwa kwesibambisi sombani sekuqediwe, kufanele kuhlolwe njalo ukuze kubhekwe ukuthi uxhumano lukhululekile yini. Uma kutholakala ukuthi idivayisi yokuvikela umbani ayisebenzi kahle noma yonakele, umphumela wokuvikela umbani wedivayisi yokuvikela umbani uzowohloka, futhi udinga ukushintshwa ngokushesha.

Imingcele evamile yesibambisi sombani wamandla
1. I-voltage yegama Un:
I-voltage elinganiselwe yesistimu evikelwe iyahambisana. Kuhlelo lobuchwepheshe bolwazi, le parameter ibonisa uhlobo lwesivikeli okufanele sikhethwe. Ibonisa inani le-rms ye-voltage ye-AC noma ye-DC.
2. I-voltage elinganiselwe Uc:
Ingasetshenziswa ekupheleni okukhethiwe komvikeli isikhathi eside ngaphandle kokubangela izinguquko ezicini zomvikeli futhi isebenze i-voltage ye-RMS ephezulu yesici sokuvikela.
3. I-Isn yokukhipha elinganiselwe:
Uma igagasi lombani elijwayelekile elinesimo segagasi esingu-8/20μs sisetshenziswa kusivikeli izikhathi ezingu-10, inani eliphakeme lamanje lokukhuphuka elingamelana nomvikeli.
4. I-Imax enkulu yokukhishwa kwamanje:
Uma igagasi lombani elijwayelekile elinefomu legagasi elingu-8/20μs lisetshenziswa kusivikeli kanye, inani eliphakeme lamanje lokukhuphuka elingamelana nomvikeli.
5. Izinga lokuvikela i-voltage Up:
Inani eliphezulu lesivikeli ekuhlolweni okulandelayo: i-flashover voltage enomthamo ongu-1KV/μs; i-voltage eyinsalela yamanje okukhiphayo okulinganiselwe.
6. Isikhathi sokuphendula:
Ukuzwela kwesenzo nesikhathi sokuqhekeka sesici sokuvikela esikhethekile esiboniswa ngokuyinhloko kusivikeli siyahlukahluka phakathi nesikhathi esithile kuye ngomthambeka we-du/dt noma di/dt.
7. Izinga lokudluliswa kwedatha Vs:
Ibonisa ukuthi mangaki amabhithi adluliswayo ngomzuzwana owodwa, iyunithi: bps; yinani eliyireferensi lokukhethwa okulungile kwamadivayisi okuvikela umbani ohlelweni lokudlulisa idatha. Izinga lokudluliswa kwedatha lamadivayisi okuvikela umbani lincike kumodi yokudlulisela yesistimu.
8. Ukulahlekelwa kokufaka Ae:
Isilinganiso sama-voltage ngaphambi nangemuva kokufakwa kwesivikeli kufrikhwensi enikeziwe.
9. Buyisela ukulahlekelwa Ar:
Imele ingxenye yegagasi elingaphambili eliboniswa kudivayisi yokuvikela (iphoyinti lokubonisa), futhi iyipharamitha ekala ngokuqondile ukuthi idivayisi yokuvikela iyahambisana yini nokuthikamezeka kwesistimu.
10. Isilinganiso esiphezulu sokukhishwa kwe-longitudinal yamanje:
Ibhekisela enanini eliphakeme lamanje lomfutho ophakeme umvikeli angamelana nalo lapho igagasi lombani elijwayelekile elinefomu legagasi elingu-8/20μs lisetshenziswa phansi kanye.
11. Umkhawulo wamanje wokuphuma kohlangothi:
Uma igagasi lombani elijwayelekile elinesimo segagasi esingu-8/20μs sisetshenziswa phakathi komugqa womunwe nolayini, inani eliphakeme lamanje lokukhuphuka elingamelana nomvikeli.
12. I-impedance eku-inthanethi:
Isho isamba se-loop impedance kanye nokusabela kwe-inductive okugeleza kusivikeli ku-voltage ye-Un. Okuvame ukubizwa ngokuthi "i-impedance yesistimu".
13. Inani eliphakeme lokukhishwa kwamandla:
Kunezinhlobo ezimbili: ukukhishwa okulinganiselwe kwe-Isn yamanje kanye nokukhishwa okuphezulu kwe-Imax yamanje.
14. Ukuvuza kwamanje:
Isho i-DC yamanje egeleza kusivikeli ku-voltage yegama engu-Un engu-75 noma engu-80.
