Umgaqo kunye noYilo lweSurge Protector Circuit Breaker

Umkhuseli wesekethe okhuselayo yeyona nto sihlala siyibiza ngokuba sisixhobo sokhuselo lotyando, esikwabizwa ngokuba ngumkhuseli wokutyanda umbane.Luhlobo lwezixhobo okanye isekethe enika ukhuseleko lokhuseleko lwezixhobo ezahlukeneyo zombane, izixhobo, kunye neesekethe zonxibelelwano.Isetyenziselwa ukufunxa i-surge or peak voltage phakathi kwegridi ye-AC ukuqinisekisa ukuba izixhobo okanye isekethe eyikhuselayo ayiyi konakala.
Umkhuseli wesiphaluka somkhuseli wokutya unokumelana nokunyuka kwamandla ombane okanye ii-spikes zamawakawaka e-volts, ewe, oku kuxhomekeke kwiiparamitha kunye neenkcukacha zomkhuseli okhethiweyo wokutya.Kukwakho nabakhuseli be-spd surge abanikezelwe kumakhulu aliqela evolthi, kuxhomekeke kwimeko yokusetyenziswa komsebenzisi.Umkhuseli wokutyanda unokumelana ne-spikes yamandla aphezulu ngephanyazo, kodwa ixesha lombane we-spike alinakuba lide kakhulu, kungenjalo umkhuseli uya kutshisa kwaye atshise ngenxa yokufunxa ngamandla.

Yintoni iSurgery?

I-Surge luhlobo lokuphazamiseka kwexeshana.Ngaphantsi kweemeko ezithile, i-voltage ye-instantaneous kwigridi yamandla idlula uluhlu lwe-voltage elinganisiweyo eqhelekileyo.Ngokubanzi, eli xeshana aliyi kuhlala ixesha elide, kodwa linokuba ne-amplitude ephezulu kakhulu.Isenokuba phezulu ngequbuliso kwisigidi nje esinye somzuzwana.Ngokomzekelo, umzuzu wombane, ukukhupha imithwalo ye-inductive, okanye ukudibanisa imithwalo emikhulu kuya kuba nefuthe elikhulu kwigridi yamandla.Kwiimeko ezininzi, ukuba izixhobo okanye isekethe eqhagamshelwe kwigridi yamandla ayinayo imilinganiselo yokukhusela i-surge, kulula ukuba isixhobo sonakaliswe, kwaye iqondo lomonakalo liya kuhambelana nomgangatho wokumelana nombane wesixhobo.

Ngaphantsi kweemeko eziqhelekileyo zokusebenza, i-voltage kwindawo yokuvavanya igcinwa kwindawo ezinzileyo ye-500V.Nangona kunjalo, ukuba i-switch q inqanyulwe ngequbuliso, ukunyuka kwamandla ombane aphezulu kuya kwenzeka kwindawo yovavanyo ngenxa yempembelelo yamandla e-electromotive ebuyela umva ngenxa yotshintsho olukhawulezileyo lwe-inductive current.

IiSekethe ezimbini zoKhuseleko lweSurgery eziQhelekileyo

1. Umkhuseli wenqanaba lokuqala lotyando

Isixhobo sokukhusela inqanaba lokuqala sihlala sifakwe emnyango wendlu okanye isakhiwo.Iya kukhusela zonke izixhobo ukusuka kwindawo yokungena yokungena ekutshutshisweni ngamaqhuqhuva.Ngokwesiqhelo, umthamo kunye nomthamo womkhuseli wenqanaba lokuqala zombini Zinkulu kakhulu kwaye ziyabiza, kodwa zibalulekile.

2. Umkhuseli wenqanaba lesibini lotyando

Inqanaba lesibini lokukhusela umkhuseli alikho likhulu kumthamo njengenqanaba lokuqala kwaye lithatha amandla amancinci, kodwa liphathekayo kakhulu.Ngokuqhelekileyo ifakwe kwindawo yokufikelela kwisixhobo sombane, njenge-socket, okanye idityaniswe kwi-front end yebhodi yamandla yezixhobo zombane ukubonelela ngesakhono sokukhusela okwesibini kwisixhobo.

Lo mzobo ulandelayo ngumzobo weskimu olula wofakelo lwesixhobo sokhuselo lokutya:

ISekethe yoKhuseleko lweSekondari yeSekondari eqhelekileyo

Kubantu abaninzi, incinci iyaziwa malunga nesekethe yokukhusela ukunyuka kwesibini, kuba uninzi lwazo ludityaniswe kwibhodi yamandla.Ibhodi ebizwa ngokuba yibhodi yamandla idla ngokuba yintloko yangaphambili yegalelo lezixhobo zombane ezininzi, ngokuqhelekileyo i-AC-AC, i-AC-DC yesiphaluka nayo isekethe efakwe ngqo kwi-socket.Indima ebaluleke kakhulu yesekethe yokukhusela umbane eyenzelwe kwibhodi yamandla kukubonelela ngokhuseleko lwangexesha xa kwenzeka utyando, njengokunqunyulwa kwesekethe okanye ukufunxa i-voltage ye-surge, yangoku.
Olunye uhlobo lwesekethe yokhuselo lotyando lwesibini, olunje nge-UPS (umbane ongaphazamisekiyo), unikezelo lwamandla ombane oluntsonkothileyo lwe-UPS luya kuba nolwakhiwo lwesekethe yokhuselo lwe-surge, enomsebenzi ofanayo nomkhuseli wokutyanda kwibhodi yonikezelo lwamandla eqhelekileyo.

Sisebenza njani isixhobo soKhuseleko lweSurgery?

Kukho umkhuseli wotyando, oya kuthi anqumle unikezelo lwamandla ngexesha xa umbane wokunyuka usenzeka.Olu hlobo lomkhuseli wotyando lukrelekrele kwaye luntsonkothile.kwaye ngokuqinisekileyo iyabiza kakhulu, kwaye ayifane isetyenziswe.Olu hlobo lwesikhuseli sotyando lubandakanya ngokubanzi inzwa yombane, isilawuli kunye ne-latch.Isivamvo sombane sijonga ikakhulu ukuba kukho ukuguquguquka kokunyuka kumbane wegridi yamandla.Umlawuli ufunda umqondiso we-voltage yokunyuka kwe-sensor ye-voltage kwaye ulawula kwangexesha i-latch njenge-on-off ye-actuator control circuit xa ijongwa njengomqondiso wokunyuka.
Kukho olunye uhlobo lwesekethe yomkhuseli wotyando, engasinqumliyo isekethe xa kukho utyando, kodwa ibamba i-voltage yokunyuka kwaye ifunxa amandla otyando.Oku kudla ngokwakhiwa kwibhodi yesekethe, njengokutshintsha iisekethe zokubonelela ngombane ziya kuba nolu hlobo lwesekethe yokukhusela ukutyhutyha.Isekethe ngokubanzi njengoko kubonisiwe kulo mfanekiso ungezantsi:

Umkhuseli we-Surge 1, ngaphesheya komda phakathi komgca ophilayo kunye nomgca ongathathi hlangothi, oko kukuthi, isiphaluka sokunciphisa imo yokwahlukana.Abakhuseli be-surge 2 kunye ne-3 ngokulandelanayo badityaniswe ngocingo oluphilayo emhlabeni kunye nocingo olungathathi hlangothi emhlabeni, oluqhelekileyo loxinzelelo lwemodi.Isixhobo sokuhlinza semowudi yokwahluka sisetyenziselwa ukucinezela kunye nokufunxa amandla ombane wokunyuka phakathi kocingo oluphilayo kunye nocingo olungathathi hlangothi.Ngendlela efanayo, isixhobo esiqhelekileyo sokunyuka kwemowudi sisetyenziselwa ukucinezela i-voltage yokunyuka kocingo lwesigaba emhlabeni.Ngokubanzi, kwanele ukufaka umkhuseli wokutyanda 1 kwimigangatho yotyando engabalulekanga kangako, kodwa ngamanye amaxesha anzima, ukhuseleko lwendlela eqhelekileyo kufuneka longezwe.

Imvelaphi ye-Voltage Surge

Kukho izinto ezininzi ezinokuvelisa i-voltage yokunyuka, ngokubanzi ngenxa yokubetha kombane, ukutshaja kwe-capacitor kunye nokukhupha, iisekethe ze-resonant, i-inductive switching circuits, ukuphazamiseka kwe-motor drive, njl.Ke ngoko, kuyimfuneko ukuyila umkhuseli wokutyanda kwisekethe.

IsiPhakathi esasasaza uTyala

Kuphela nge-propagation medium efanelekileyo, i-voltage yokunyuka inethuba lokutshabalalisa izixhobo zombane.

Intambo yamandla-Intambo yombane yeyona ndlela ibalulekileyo kunye neyona ndlela ichanekileyo yokusasaza ukunyuka, kuba phantse zonke izixhobo zombane zixhotyiswa ngentambo yombane, kwaye uthungelwano losasazo lweentambo zombane lukho kuyo yonke indawo.

Amaza onomathotholo-enyanisweni, eyona ndawo yokungena yi-eriyali, ekulula ukufumana i-wireless surges okanye ukubetha kombane, okunokwaphula izixhobo zombane ngephanyazo.Xa umbane ubetha i-eriyali, igqobhoza isamkeli samaza kanomathotholo.

I-Alternator-Kummandla wombane weemoto, ukunyuka kwamandla ombane kuya kuchazwa ngogxininiso.Rhoqo xa i-alternator ineenguqu ezintsonkothileyo, umbane omkhulu wokunyuka uya kwenziwa.

I-inductive circuit-xa i-voltage kwiziphelo zombini ze-inductor itshintsha ngokukhawuleza, i-voltage yokunyuka ihlala iveliswa.

Uyilwa njani iSekethi yoKhuseleko lweSurgery

Akunzima ukuyila isiphaluka sokukhusela i-surge.Enyanisweni, ukuyila isiphaluka sokukhusela esakhelwe ngaphakathi, eyona ndlela ilula ifuna kuphela icandelo elinye, oko kukuthi, i-MOV varistor okanye i-TVS ye-diode edlulayo.Njengoko kubonisiwe kumzobo ongezantsi, abakhuseli botyando 1-3 banokuba yi-varistors MOV okanye iTVS.

Ngamanye amaxesha, kuyimfuneko kuphela ukudibanisa i-varistor ye-MOV ngokuhambelana phakathi komgca ongathathi hlangothi wombane we-AC ukuhlangabezana nomgangatho we-IEC.Kwizicelo ezininzi, kuyimfuneko ukongeza isiphaluka sokukhusela i-surge phakathi kwe-zero yocingo oluphilayo kunye nomhlaba ngexesha elifanayo ukuhlangabezana neemfuno eziphezulu zokunyuka, umzekelo, imfuno iphezulu kune-4KV.

Surge uMkhuseli weVaristor MOV

Iimpawu eziphambili ze-MOV

1. I-MOV imele i-Metal oxide varistor, i-metal oxide resistor, ixabiso layo lokumelana liya kutshintsha ngokuhambelana nombane kwi-resistor.Idla ngokusetyenziswa phakathi kweegridi zamandla e-AC ukujongana nombane wokunyuka.
2. I-MOV sisixhobo esikhethekileyo esisekelwe kumbane.
3. Xa i-MOV isebenza, iimpawu zayo zifana ne-diode, ezingekho-linear kwaye azifanelekanga kumthetho we-Ohm, kodwa iimpawu zayo zombane kunye neempawu zangoku ziyi-bidirectional, ngelixa i-diode i-unidirectional.
4. Ifana kakhulu ne-TVS diode ye-bidirectional.
5. Xa i-voltage kwi-varistor ayifiki kwi-voltage ye-clamp, ikwimeko yesiphaluka evulekileyo.

Ukukhethwa kwendawo yeVaristor kwiSekethe yoKhuseleko lweSurgery

I-varistor yinto ebalulekileyo kumkhuseli wokutya.Xa uyila, qiniseka ukuba isondele ngokusemandleni kwi-fuse ekupheleni kwegalelo, njengoko kuboniswe kumzobo ongezantsi.Ngale ndlela, kunokuqinisekiswa ukuba i-fuse inokuvuthwa ngexesha xa i-surge current isenzeka, kwaye isiphaluka esilandelayo sikwimeko evulekileyo ukuphepha umonakalo omkhulu okanye nomlilo obangelwa yi-current current.
