IEC 61643-31: 2018 Izixhobo zokukhusela amandla asezantsi-Icandelo 31: Izidingo kunye neendlela zovavanyo lwee-SPD zokufakwa kwe-photovoltaic

I-IEC 61643-31: I-2018 isebenza kwizixhobo ezikhuselekileyo zoKhuseleko (i-SPDs), ejolise ekukhuseleni ukukhuselwa kwiziphumo ezingathanga ngqo nezingqalileyo zombane okanye ezinye izinto ezihamba kancinci okwexeshana. Ezi zixhobo ziyilelwe ukuba ziqhagamshelwe kwicala le-DC lofakelo lwe-photovoltaic olulinganiswe ukuya kwi-1 500 V DC. Ezi zixhobo ziqulathe ubuncinci inqaku elinye elingelolayini kwaye zijolise ekunciphiseni ukunyuka kwe-voltages kunye nokuphambukisa imisinga yokunyuka. Iimpawu zokusebenza, iimfuno zokhuseleko, iindlela eziqhelekileyo zokuvavanya kunye nokulinganisa zisekiwe. 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. Ii-SPDs ezineegalelo ezahlukeneyo kunye neetheminali zokuphuma eziqulethe ukungqinelani okuthile phakathi kwezi zixhobo (ezibizwa ngokuba zii-SPDs ezibini ezibini ngokwe-IEC 61643-11: 2011) ezingagutyungelwanga. Ii-SPDs ezithobela lo mgangatho ziyilelwe ukuba zidityaniswe ngokusisigxina apho unxibelelwano kunye nokucinywa kwee-SPDs ezinokuthi zenziwe kuphela kusetyenziswa isixhobo. Lo mgangatho awusebenzi kwii-SPD eziphathekayo.
