Indlela yokufaka i-power surge arrester
1. Faka isivikelo sombani wamandla ngesikhathi esifanayo. Indawo yokufaka umshini wamalahle ingemuva kwebhodi lokushintsha noma iswishi yommese (i-circuit breaker) ekilasini lendawo yokubuka yesathelayithi. Sebenzisa amasethi amane okwandiswa kwepulasitiki ye-M8 kanye nezikulufo zokuzithinta ezifanayo odongeni.
2. Usayizi wokufakwa (70×180) kanye nezimbobo zokufakwa ezifanele ku-power arrester kufanele zibholwe odongeni.
3. Xhuma ugesi. Intambo ephilayo yesibambisi-mandla ibomvu, intambo engathathi hlangothi iluhlaza okwesibhakabhaka, kanti indawo yesigaba esinqamulelayo yi-BVR6mm2. Intambo yethusi enezintambo eziningi, intambo yomhlabathi yomshini wamalahle iphuzi futhi iluhlaza okotshani, kanti indawo yesigaba esinqamulelayo yi-BVR10m m2. Intambo yethusi enqamulelayo, ubude bentambo bungaphansi noma bulingana no-500mm. Uma umkhawulo ungaphansi noma ulingana no-500mm, ungandiswa ngendlela efanele, kodwa isimiso sokugcina intambo imfushane ngangokunokwenzeka kufanele silandelwe, futhi ikona kufanele libe ngaphezu kwama-degrees angu-90 (umugqa kunokuba kwesokudla).
4. Xhuma ugesi kumqhubi wombani. Ukuphela kwekhebula lokuvimba ugesi kuboshwe ngqo futhi kuqinile esigungwini sokuvimbela ugesi. Intambo yokuvimba ixhunywe kugridi yokuvimba ugesi ezimele noma ucingo lokuvimba ugesi olunezigaba ezintathu olunikezwa yisikole.

Izinyathelo zokuphepha zokufaka i-power surge arrester
1. Isiqondiso sezintambo
Uma kufakwa isivikelo sombani, amatheminali okufaka nawokukhipha akumele axhunywe ngokubuyela emuva, ngaphandle kwalokho, umphumela wokuvikela umbani uzothinteka kakhulu, futhi ngisho nokusebenza okuvamile kwemishini kuzothinteka. Ukuphela kokufaka kwesivikelo sombani kuhlobene nesiqondiso sokusabalala kwegagasi lombani, okungukuthi, ukuphela kokufaka kwesiphakeli, futhi ukuphela kokukhipha kuwukuvikela imishini.
2. Indlela yokuxhuma
Kunezinhlobo ezimbili zezindlela zokuxhuma: uxhumano lochungechunge kanye noxhumano oluhambisanayo. Ngokuvamile, kusetshenziswa indlela yokuxhuma yesiphetho kuphela endleleni yokuxhuma yochungechunge, kanti enye indlela yokuxhuma isetshenziswa endleleni yokuxhumanisa ehambisanayo. Intambo engathathi hlangothi yekhebula likagesi ixhunywe emgodini wokuxhuma we-"N" we-SPD yamandla, futhi ekugcineni intambo yomhlabathi ethathwe emgodini wokuxhuma we-"PE" we-SPD yamandla ixhunywe kubha yebhasi yokuvikela umbani noma kubha yokuvikela umbani. Ngaphezu kwalokho, indawo encane enqamulayo yentambo yokuxhuma ye-lightning arrester kufanele ihambisane nezinhlinzeko ezifanele zephrojekthi yokuvikela umbani kazwelonke.

3. Ukuxhumeka kwentambo ephansi
Ubude bokumisa phansi kwentambo yokumisa phansi kufanele bube bufushane ngangokunokwenzeka, uhlangothi olulodwa kufanele luboshwe ngqo esigungwini sokubopha umbani, futhi ucingo lokumisa phansi kufanele luxhunywe kunethiwekhi yokumisa phansi ezimele (ehlukanisiwe nokumisa phansi kukagesi) noma luxhunywe kuntambo yokumisa phansi ekuhlinzekweni kwamandla kwezigaba ezintathu.
4. Indawo yokufaka
Isivikelo sombani esihlinzeka ngogesi ngokuvamile sisebenzisa indlela yokuvikela esezingeni eliphezulu. Faka idivayisi yokuvikela umbani eyinhloko ekhabetheni elikhulu lokusabalalisa ugesi lesakhiwo. Okwesibili, faka idivayisi yesibili yokuvikela umbani esivikelo sombani esingaphansi kwamandla esakhiwo lapho kukhona khona imishini kagesi. Ngaphambili kwemishini ebalulekile kagesi, faka isivikelo sombani esinamandla esinamazinga amathathu, futhi ngesikhathi esifanayo, uqinisekise ukuthi azikho izinto ezivuthayo neziqhumayo eduze kokufakwa ukuvimbela umlilo obangelwa yizinhlansi zikagesi.
5. Ukusebenza kokuvala ugesi
Ngesikhathi sokufakwa, ugesi kumele unqanyulwe, futhi ukusebenza bukhoma akuvunyelwe ngokuphelele. Ngaphambi kokusebenza, i-multimeter kumele isetshenziswe ukuhlola ukuthi amabha noma amatheminali esigaba ngasinye acinywe ngokuphelele.
6. Hlola izintambo
Hlola ukuthi izintambo zithintana yini. Uma kukhona ukuxhumana, bhekana nakho ngokushesha ukuze ugweme ukujikeleza okufushane kwemishini. Ngemva kokufakwa kwe-light arrester sekuqediwe, kufanele kuhlolwe njalo ukuze kuhlolwe ukuthi ukuxhumana kukhululekile yini. Uma kutholakala ukuthi idivayisi yokuvikela umbani ayisebenzi kahle noma yonakele, umphumela wokuvikela umbani wedivayisi yokuvikela umbani uzowohloka, futhi udinga ukushintshwa ngokushesha.

Imingcele evamile ye-power lightning arrester
1. I-voltage ejwayelekile:
I-voltage elinganisiwe yesistimu evikelwe iyahambisana. Kuhlelo lobuchwepheshe bolwazi, le parameter ikhombisa uhlobo lwesivikelo okufanele sikhethwe. Ibonisa inani le-rms le-voltage ye-AC noma ye-DC.
2. I-voltage ekalwe nge-Uc:
Ingasetshenziswa ekugcineni okuqokiwe kwesivikelo isikhathi eside ngaphandle kokubangela izinguquko ezimfanelweni zesivikelo futhi kusebenze i-voltage ephezulu ye-RMS yento yokuvikela.
3. Isilinganiso samanje sokukhipha:
Uma igagasi lombani elijwayelekile elinesimo samagagasi esingu-8/20μs lisetshenziswa kumvikeli izikhathi eziyi-10, inani eliphakeme kakhulu lamandla okukhuphuka umvikeli angalimela.
4. Umkhawulo wamanje wokukhipha okuphezulu:
Uma igagasi lombani elijwayelekile elinesimo samagagasi esingu-8/20μs lisetshenziswa kumvikeli kanye, inani eliphakeme kakhulu lamandla okukhuphuka umvikeli angalimela.
5. Izinga lokuvikela i-voltage Liya phezulu:
Inani eliphezulu lesivikelo kulezi zivivinyo ezilandelayo: i-voltage ye-flashover enokwehla okungu-1KV/μs; i-voltage eseleyo yamanje okukhiphayo okulinganiselwe.
6. Isikhathi sokuphendula i-tA:
Ukuzwela kwesenzo kanye nesikhathi sokuqhekeka kwento ekhethekile yokuvikela ebonakala kakhulu kumvikeli kuyahlukahluka phakathi nesikhathi esithile kuye ngokuthi i-du/dt noma i-di/dt iguquguquka kanjani.
7. Izinga lokudluliswa kwedatha vs:
Ibonisa ukuthi zingaki izingcezu ezidluliselwa ngomzuzwana owodwa, iyunithi: ama-bps; iyinani elibhekisela ekukhetheni okulungile kwamadivayisi okuvikela umbani ohlelweni lokudlulisa idatha. Izinga lokudlulisa idatha yamadivayisi okuvikela umbani lincike kwimodi yokudlulisa uhlelo.
8. Ukulahlekelwa kokufakwa kwe-Ae:
Isilinganiso sama-voltage ngaphambi nangemva kokufakwa kwesivikelo ngemvamisa ethile.
9. Ukulahlekelwa kokubuyiselwa Ar:
Imelela ingxenye yegagasi langaphambili eliboniswa kudivayisi yokuvikela (indawo yokubonisa), futhi iyipharamitha elinganisa ngqo ukuthi idivayisi yokuvikela iyahambisana yini ne-impedance yesistimu.
10. Ukukhishwa kwamandla okukhipha isikhathi eside okuphezulu:
Kubhekisele enanini eliphakeme kakhulu lamanje lokucindezela elingase limelelwe yisivikelo lapho igagasi lombani elijwayelekile elinesimo samagagasi esingu-8/20μs lifakwa emhlabathini kanye.
11. Umkhawulo ophezulu wokukhipha ugesi ohlangothini:
Uma kusetshenziswa igagasi lombani elijwayelekile elinesimo samagagasi esingu-8/20μs phakathi komugqa womunwe nomugqa, inani eliphakeme kakhulu lamandla okukhuphuka angasetshenziswa ngumvikeli.
12. Ukuvimba kwe-inthanethi:
Kubhekiselwa kwisamba se-loop impedance kanye ne-inductive reactionance egeleza ngesivikelo ku-voltage ejwayelekile ye-Un. Ngokuvamile ibizwa ngokuthi “i-system impedance”.
13. Ukukhishwa kwamanje okuphezulu:
Kunezinhlobo ezimbili: i-Isn elinganisiwe kanye ne-Imax enikhulu yokukhipha amandla.
14. Ukuvuza kwamanje:
Kubhekisele kugesi we-DC ogeleza ngesivikelo ku-voltage ejwayelekile engu-Un engu-75 noma engu-80.
