Indlela yokufaka isixhobo sokuthintela ukwanda kwamandla
1. Faka isixhobo sokuthintela umbane ngamandla ngaxeshanye. Indawo yokufakela umatshini wamalahle ngasemva kwebhodi yokutshintsha okanye iswitshi yemela (i-circuit breaker) kwigumbi lokufundela lendawo yokubukela yesathelayithi. Sebenzisa iiseti ezine zeplastiki ye-M8 expansion kunye nezikrufu zokuzichukumisa ezihambelanayo eludongeni.
2. Ubungakanani bofakelo (70×180) kunye nemingxunya yofakelo ehambelanayo kwisithinteli sombane kufuneka igqojwe eludongeni.
3. Qhagamshela umbane. Intambo ephilayo yesixhobo sokuthintela umbane ibomvu, intambo engathathi cala iluhlaza okwesibhakabhaka, kwaye indawo enqamlezileyo yi-BVR6mm2. Intambo yobhedu enemicu emininzi, intambo yomhlaba yomatshini wamalahle ityheli kwaye iluhlaza, kwaye indawo enqamlezileyo yi-BVR10m m2. Intambo yobhedu enqamlezileyo, ubude bentambo bungaphantsi okanye bulingana ne-500mm. Ukuba umda ungaphantsi okanye ulingana ne-500mm, unokwandiswa ngokufanelekileyo, kodwa umgaqo wokugcina intambo imfutshane kangangoko kufuneka ulandelwe, kwaye ikona kufuneka ibe ngaphezu kwe-90 degrees (i-arc endaweni yasekunene).
4. Qhagamshela umbane kwi-lightning conductor. Isiphelo esinye sentambo yokuthintela umbane sibotshelelwe ngokuthe ngqo nangokuqinileyo kwisiphelo se-power arrester. Ucingo lokuthintela umbane luqhagamshelwe kwigridi yokuthintela umbane ezimeleyo okanye ucingo lokuthintela umbane olunezigaba ezintathu olunikezelwa sisikolo.

Amanyathelo okukhusela xa kufakelwa isixhobo sokuthintela ukusasazeka kwamandla
1. Isikhokelo socingo
Xa kufakwe isixhobo sokuvalela umbane, ii-terminals zokufaka kunye nezokukhupha akufuneki ziqhagamshelwe ngasemva, kungenjalo, isiphumo sokukhusela umbane siya kuchaphazeleka kakhulu, kwaye nokusebenza okuqhelekileyo kwesixhobo kuya kuchaphazeleka. Isiphelo sokufaka sesixhobo sokuvalela umbane sihambelana necala lokusasazeka kwegagasi lombane, oko kukuthi, isiphelo sokufaka sesixhobo sokutya, kwaye isiphelo sokukhupha kukukhusela isixhobo.
2. Indlela yoqhagamshelo
Kukho iintlobo ezimbini zeendlela zokuxhuma: uqhagamshelo lochungechunge kunye noqhagamshelo oluhambelanayo. Ngokubanzi, yindlela yoqhagamshelo lwesiphelo kuphela esetyenziswa kwindlela yoqhagamshelo lochungechunge, kwaye enye indlela yoqhagamshelo isetyenziswa kwindlela yoqhagamshelo oluhambelanayo. Intambo engathathi cala yentambo yamandla iqhagamshelwe kumngxuma wocingo "we-N" we-SPD yamandla, kwaye ekugqibeleni intambo yomhlaba ethathwe kumngxuma wocingo "we-PE" we-SPD yamandla iqhagamshelwe kwi-busbar yokukhusela umbane okanye kwi-grounding bar yokukhusela umbane. Ukongeza, indawo encinci ye-cross-sectional yentambo yokudibanisa ye-lightning arrester kufuneka ihambelane nemigaqo efanelekileyo yeprojekthi yokukhusela umbane yesizwe.

3. Uqhagamshelo lwentambo esezantsi
Ubude bomhlaba ophantsi kocingo lokumisa umhlaba kufuneka bube bufutshane kangangoko, elinye icala lifanele livalwe ngqo kwisiphelo sesixhobo sokumisa umbane, kwaye ucingo lokumisa umhlaba kufuneka luqhagamshelwe kwinethiwekhi yokumisa umhlaba ezimeleyo (eyahlulwe kwisiseko sombane) okanye iqhagamshelwe kwintambo yokumisa umhlaba kumbane wamanqanaba amathathu.
4. Indawo yokufakelwa
Isithinteli sombane esibonelela ngombane ngokubanzi sisebenzisa indlela yokukhusela elinganisiweyo. Faka isixhobo sokukhusela umbane esiphambili kwikhabhathi ephambili yokusasaza umbane yesakhiwo. Okwesibini, faka isixhobo sokukhusela umbane esibonelela ngombane esisezantsi kwisibonelelo sombane sesakhiwo apho kukho izixhobo ze-elektroniki. Ngaphambili kwezixhobo ze-elektroniki ezibalulekileyo, faka isithinteli sombane esinamanqanaba amathathu, kwaye kwangaxeshanye, qinisekisa ukuba akukho zinto zitshayo neziqhumayo kufutshane nofakelo ukuthintela umlilo obangelwa ziintlantsi zombane.
5. Ukusebenza kokucima umbane
Ngexesha lokufakelwa, umbane kufuneka ucinywe, kwaye ukusebenza kwawo ngqo akuvumelekanga. Ngaphambi kokusebenza, kufuneka kusetyenziswe i-multimeter ukuvavanya ukuba iibhasi okanye iiterminal zecandelo ngalinye zicinywe ngokupheleleyo.
6. Jonga iingcingo
Jonga ukuba iingcingo zidibene na. Ukuba kukho unxibelelwano, yijongane nayo ngokukhawuleza ukuze kuthintelwe ukujikeleza okufutshane kwezixhobo. Emva kokuba kugqityiwe ukufakwa kwesixhobo sokuthintela umbane, kufuneka sihlolwe rhoqo ukuze kuhlolwe ukuba unxibelelwano lukhululekile na. Ukuba kufunyenwe ukuba isixhobo sokukhusela umbane asisebenzi kakuhle okanye sonakele, isiphumo sokukhusela umbane sesixhobo sokukhusela umbane siya kuba sibi, kwaye kufuneka sitshintshwe ngoko nangoko.

7. Izinga lokudluliselwa kwedatha vs:
Ibonisa ukuba zingaphi iibhithi ezithunyelwayo kwisekhondi enye, iyunithi: i-bps; lixabiso lesalathiso sokukhetha ngokuchanekileyo izixhobo zokukhusela umbane kwinkqubo yokudlulisa idatha. Izinga lokudlulisela idatha yezixhobo zokukhusela umbane lixhomekeke kwindlela yokudlulisela inkqubo.
8. Ukulahleka kokufakwa kwe-Ae:
Umlinganiselo wee-voltages ngaphambi nasemva kokufakwa kwesikhuseli kwi-frequency ethile.
9. Ukulahleka kokubuyisela Ar:
Imele umlinganiselo wegagasi langaphambili elibonakaliswa kwisixhobo sokukhusela (indawo yokubonakalisa), kwaye yiparameter elinganisa ngokuthe ngqo ukuba isixhobo sokukhusela siyahambelana na ne-system impedance.
10. Ubuninzi bokukhupha umbane obude:
Ibhekisa kwixabiso eliphezulu le-intrust current peak elinokumelana nomkhuseli xa igagasi lombane eliqhelekileyo eline-waveform ye-8/20μs lifakwa emhlabeni kanye.
11. Umbane ophezulu wokukhupha ecaleni:
Xa kusetyenziswa igagasi lombane eliqhelekileyo eline-waveform ye-8/20μs phakathi komgca womnwe kunye nomgca, ixabiso eliphezulu le-surge current current elinokumelana nalo umkhuseli.
12. Ukuthintela kwi-intanethi:
Ibhekisa kwinani le-loop impedance kunye ne-inductive reactance edlula kwi-protector kwi-nominal voltage Un. Idla ngokubizwa ngokuba yi-"system impedance".
