Izigaba zokuLawulwa kweziDivayisi zokuVikela
Esihlokweni esandulele, safaka esinye sezigaba zokuzivikela kokuvikela, okungukuthi, ngohlobo noma ekilasini. Thayipha i-1 / 2 / 3 isigaba esivamile kakhulu se-SPD noma sezingeni elijwayelekile le-UL noma i-IEC. Ungabuyekeza lesi sihloko ngalesi sixhumanisi:
Futhi kule ngqungquthela, sizokhuluma kabanzi ngezinye izigaba ezingafakwa esithombeni esingenhla.
I-AC SPD & DC / PV SPD
Ngokusobala, i-AC SPD ivame kakhulu kune-DC SPD njengoba sonke sihlala emphakathini lapho imikhiqizo eminingi kagesi inikwa amandla yi-AC ngenxa kaThomas Edison. Mhlawumbe yingakho izinga le-IEC 61643-11 lisebenza kuphela kudivayisi yokuvikela i-AC isikhathi eside impela ayikho indinganiso esebenzayo ye-IEC yedivayisi yokuvikela i-DC. I-DC SPD ithandwa njengokwanda kwemboni yamandla elanga futhi abantu bayaqaphela ukuthi ukufakwa kwe-PV kuyisisulu esivamile sombani njengoba kuvame ukutholakala endaweni evulekile noma ophahleni lwendlu. Ngakho-ke isidingo samadivayisi wokuvikela ukuqhuma kohlelo lokusebenza lwe-PV sikhula ngokushesha phakathi neminyaka eyi-10 edlule. Umkhakha we-PV uhlelo oluvame kakhulu futhi oludumile lwe-DC SPD.
Ochwepheshe bokuvikelwa kokuqubuka kanye nenhlangano bayabona ukuthi i-IEC 61643-11 etholakalayo ayiyona indinganiso ephelele ye-PV SPD njengoba isebenza kuphela ohlelweni lwamandla kagesi aphansi ngaphansi kwe-1000V. Kodwa amandla kagesi we-PV angafika ku-1500V. Ngakho-ke, kwethulwe izinga elisha elibizwa nge-EN 50539-11 ukubhekana nale nkinga. I-IEC nayo yasabela kulesi simo futhi yethula i-IEC 61643-31 ukuze kusetshenziswe i-PV SPD ngo-2018.
IEC 61643-11: 2011
Amadivayisi wokuvikela amandla aphansi - Ingxenye 11: Amadivayisi wokuvikela akhuphukile axhunywe kumasistimu amandla kagesi anamandla aphansi - Izidingo nezindlela zokuhlola
I-IEC 61643-11: I-2011 isebenza kumadivayisi okuvikela ukuqhuma ngokumelene nemiphumela engaqondakali kanye nemiphumela eqondile yombane noma ezinye izikhukhula ezingapheliyo. Lawa madivayisi ahlanganiswe ukuze axhumeke kuma-circuits e-50 / 60 Hz yamandla, nemishini elinganiselwe ku-1 000 V ama-rms Izici zomsebenzi, izindlela ezijwayelekile zokuhlolwa nokulinganisa zisungulwa. Lawa madivayisi aqukethe okungenani ingxenye eyodwa ye-nonlinear futhi ahloswe ukunciphisa imigoqo yokukhuphuka nokuguqula izimpande zokungena.
IEC 61643-31: 2018
Amadivayisi wokuvikela ama-low-voltage - Ingxenye 31: Izidingo nezindlela zokuhlola ze-SPDs zokufakwa kwe-photovoltaic
I-IEC 61643-31: I-2018 isebenza kumaSurge Protective Devices (SPDs), ahloselwe ukuvikela ukukhuphuka emiphumeleni engaqondile nengaqondile yombani noma okunye okweqisayo okungapheli. Lawa madivayisi aklanyelwe ukuxhumeka ohlangothini lwe-DC lokufakwa kwe-photovoltaic okulinganiselwe kufika ku-1 500 V DC. Lawa madivayisi aqukethe okungenani into eyodwa engekho emgqeni futhi enzelwe ukukhawulela ukuqhuma kwamagagasi nokuguqula imisinga yokuqhuma. Izici zokusebenza, izidingo zokuphepha, izindlela ezijwayelekile zokuhlola nezilinganiso ziyasungulwa. Ama-SPD ahambisana naleli zinga anikezelwe ngokukhethekile ukuthi afakwe ohlangothini lwe-DC lwama-generator we-photovoltaic nohlangothi lwe-DC lwama-inverters. Ama-SPD wezinhlelo ze-PV ezinesitoreji samandla (isb. Amabhethri, amabhange ama-capacitor) awahlanganiswa. Ama-SPD anezikhala ezihlukile zokufaka nezokukhipha eziqukethe i-impedance yochungechunge oluthile phakathi kwalezi zindawo (ezibizwa ngama-SPDs amachweba amabili ngokwe-IEC 61643-11: 2011) azimboziwe. Ama-SPD ahambisana naleli zinga aklanyelwe ukuxhunyaniswa unomphela lapho ukuxhumeka nokunqanyulwa kwama-SPD ahleliwe kungenziwa kuphela kusetshenziswa ithuluzi. Leli zinga alisebenzi kuma-SPD aphathekayo.
Lokhu kunguquko ejwayelekile ye-IEC. Ngo-standard standard ye-UL, uhlelo olusha lwe-UL 1449 4th lunikeze okuqukethwe kwe-PV SPD engekho emhlanganweni we-3rd. Ngakho ekugcineni, zonke izinhlangano ezijwayelekile ziqalise izindinganiso zazo zokuvikela i-DC / PV.
Ake sibheke ama-PV SPDs kaProsurge.
Ukuze uthole ukwaziswa okwengeziwe mayelana Idivayisi yedivayisi yokuvikela i-DC / PV, sicela uvakashele leli khasi:
UkuLawulwa kokuPhepha kokuPhezulu kwezicelo
Ngokwesiko, amadivaysi okuvikelwa kokukhuphuka angenziwa ngezigaba ezinjenge:
- I-SPD yokunikezwa kwamandla
- I-SPD yeSignal
- I-SPD yevidiyo
- I-SPD yeNethiwekhi
- i-ect
Lapha sibona ezinye zezithombe ze-SPD kulesi sigaba.
I-SPD ye-Power Supply
I-SPD yeSignal
I-SPD ye-Ethernet
I-SPD yevidiyo
Ukumiswa kwe-SPD ngokuKhanya / Ukubukeka
Ngokuvamile, ngaphandle kohlobo lwe-3 SPDs oluvame ukubhekisela emigqeni yamandla kanye nezindwangu futhi zamukele umgudu we-plug-in. Kunezintambo ezimbili ezijwayelekile: ukufakwa kwe-DIN-rail nokuphakanyiswa kwephaneli. Nazi izithombe ze-DD-rail railing SPD kanye ne-SPD eqhubekayo ye-Panel.
Singaqaphela ngokucacile ukuthi banezinkinga ezihlukile.
I-Panel iphakanyisiwe i-SPD
I-DIN-isitimela i-SPD ekhishwe
Ake sibheke ezinye zezithombe zabo zokufaka ukuze siqonde kangcono ukuthi la ma-SPD afakwa kanjani.
I-Panel iphakanyisiwe i-SPD
I-DIN-isitimela i-SPD ekhishwe
Isifinyezo
Kulesi sihloko, sithuthukisa ingxoxo yethu ekwenzeni idivayisi yokuzivikela. Sikhuluma ngokuhlukaniswa kwe-AC / DC, ngezicelo nangokufakwa. Yiqiniso, kunezinye izindinganiso okufanele zihlukaniswe futhi zizithoba. Sithemba ukuthi lesi sihloko singakusiza ukuthi uqonde idivayisi yokuvikelwa okungcono kakhulu.
