Ukhuselo lweeNkcukacha zoKhuseleko

Kwinqaku elidlulileyo, sazisa esinye sesigaba sokukhusela isixhobo sokukhusela, oko kukuthi, ngohlobo okanye kwiklasi. Uhlobo lwe-1 / 2 / 3 uluhlu oluqhelekileyo lwe-SPD okanye kwi-standard standard ye-UL okanye i-IEC. Unokuyihlolisisa eli nqaku ngekhonkco:

Isixhobo sokuKhuselwa kwesiCwangciso: Isingeniso esona siqonde kakhulu

Kwaye kweli nqaku, siza kuthetha ngakumbi malunga nezinye izigaba ezingabonakalwanga kwinqaku elingentla.

I-AC SPD kunye neDC / PV SPD

Ngokucacileyo, i-AC SPD ixhaphake kakhulu kune-DC SPD njengoko sonke sihlala kuluntu apho uninzi lweemveliso zombane zixhotyiswa ngumbulelo wangoku we-AC kuThomas Edison. Mhlawumbi yiloo nto umgangatho we-IEC 61643-11 usebenza kuphela kwisixhobo sokukhusela i-AC ixesha elide akukho meko ifanelekileyo ye-IEC yesixhobo sokukhusela iDC. I-DC SPD iyathandwa njengokunyuka kweshishini lamandla elanga kwaye abantu bayaqaphela ukuba ufakelo lwe-PV lixhoba eliqhelekileyo lombane njengoko ihlala ibekwe kwindawo evulekileyo okanye eluphahleni. Ke isidingo sesixhobo sokukhusela izixhobo ze-PV sikhula ngokukhawuleza kule minyaka ili-10 idlulileyo. Icandelo le-PV sesona sixhobo siqhelekileyo nesithandwayo kwi-DC SPD.

Ukukhuselwa kwabaqeqeshi kunye nentlangano iyaqonda ukuba i-IEC 61643-11 yokuhamba ayisiyomgangatho ugqibeleleyo we-PV SPD njengoko isebenza kuphela kwinkqubo yamandla ombane aphantsi kwe-1000V. Okwangoku inkqubo yombane ye-PV inokufikelela kwi-1500V. Ke ngoko, umgangatho omtsha obizwa ngokuba yi-EN 50539-11 usungulwe ukujongana nale ngxaki. I-IEC iphinde yasabela kule meko kwaye yasungula i-IEC 61643-31 yokusetyenziswa kwe-PV SPD kwi-2018.

IEC 61643-11: 2011

Izixhobo zokukhusela izixhobo ezinamandla asezantsi-Icandelo le-11: Izixhobo zokukhusela izixhobo ezixhumeke kwiinkqubo zamandla ombane ophantsi -Iimfuneko kunye neendlela zovavanyo

IEC 61643-11: I-2011 isebenza kwizixhobo zokukhusela ngokukhawuleza ngokungathanga ngqo kunye nemiphumo ngqo yombane okanye ezinye izikhukhula ezingapheliyo. Ezi zixhobo zifakwe kwi-50 / 60 i-Hz zamandla zombane, kunye nezixhobo ezilinganiselwe kwi-1 000 V Iimpawu zendlela yokusebenza, iindlela eziqhelekileyo zokuvavanya kunye nokulinganisa kusekwe. Ezi zixhobo ziqulethe ubuncinane enye inxalenye engezantsi kwaye zijoliswe ekunciphiseni imilinganiselo yokunyuka kunye nokuguqula imirhupha.

IEC 61643-31: 2018 

Izixhobo zokukhusela izixhobo ezinamandla asezantsi-Icandelo 31: Iimfuno kunye neendlela zovavanyo lwee-SPD zokufakwa kwe-photovoltaic

I-IEC 61643-31: I-2018 isebenza kwii-Surge Protect Devices (SPDs), ejoliswe ekukhuseleni ukukhuselwa kwimiphumo engathanga ngqo kunye ngqo kunye nombane okanye ezinye izinto ezigqithiseleyo. Ezi zixhobo ziyilelwe ukuba zidityaniswe kwicala le-DC lofakelo lwe-photovoltaic elinganiselwe ukuya kwi-1 500 V DC. Ezi zixhobo ziqulathe ubuncinci inqaku elinye elingelolayini kwaye zijolise ekunciphiseni ukunyuka kwe-voltages kunye nokuphambukisa imisinga yokunyuka. Iimpawu zomsebenzi, iimfuno zokhuseleko, iindlela ezisemgangathweni zovavanyo kunye nokulinganiswa kumiselwe. Ii-SPDs ezithobela lo mgangatho zinikezelwe ngokukodwa ukuba zifakwe kwicala le-DC leefoto ze-photovoltaic kunye ne-DC ye-inverters. Ii-SPDs zeenkqubo ze-PV ezinokugcinwa kwamandla (umz. Iibhetri, iibhanki ze-capacitor) azikhutshiwe. Ii-SPDs ezinamagalelo ahlukeneyo kunye neziphumo eziqulethe ukungqinelana kothotho phakathi kwezi zixhobo (ezibizwa ngokuba zii-SPDs ezibini ngokwe-IEC 61643-11: 2011) ezingagutyungelwanga. Ii-SPDs ezithobela lo mgangatho ziyilelwe ukunxibelelana ngokusisigxina apho unxibelelwano kunye nokuqhawulwa kwe-SPDs ezinzileyo kunokwenziwa kuphela kusetyenziswa isixhobo. Lo mgangatho awusebenzi kwii-SPD eziphathekayo.

Olu tshintsho kumgangatho we-IEC. Ngomgangatho we-UL, i-UL 1449 4th yakamuva ipapashwe i-PV SPD engekho kwi-3rd edition. Ngoko ekugqibeleni, yonke imibutho ephantsi iqalise imigangatho yokukhusela i-DC / PV kwisixhobo sokukhusela.

Makhe sijonge kwi-Prosurge's PV SPDs.

UkuLawulwa koKhuselo lweeSicelo

Ngokwesiko, iifowuni zokukhusela ezikhuselweyo zingabalwa ngezicelo ezifana:

  • SPD yokunikezelwa kwamandla
  • SPD yeSignal
  • SPD kwiVidiyo
  • SPD yeNethiwekhi

Ukwahlulelwa kwe-SPD ngokuGcina / ukuBonakala

Ngokuqhelekileyo, ngaphandle kohlobo lwe-3 SPDs oluqhelekileyo lubhekisela kumagqabha kagesi kunye neendawo zokungenisa kunye nokwamkela i-plug-in moutning. Kukho iintambo ezimbini eziqhelekileyo: ukulungiswa kwe-DIN-rail kunye ne-panel panel. Nantsi imifanekiso ye-DIN-rail ye-SPD kunye ne-SPD yokubeka i-Panel.

Singaqaphela ngokucacileyo ukuba baneemvavanyo ezihlukeneyo.

isishwankathelo

Kule nqaku, siphendule ingxoxo yethu kwiklasi yecebo lokukhusela. Sithetha malunga nokuhlukanisa i-AC / DC, ngezicelo kunye nokufakela. Ewe, kukho enye imilinganiselo yokuhlenga kunye kwaye iyazimela. Siyathemba ukuba eli nqaku lingakunceda uqonde i-device yokukhusela.
