31、 photovoltaic energy systems 1 General IEC 60269-1 applies with the following supplementary requirements. Fuse-links for the protection of solar photovoltaic (PV) energy systems shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the

32、supplementary requirements laid down below. NOTE The abbreviation “PV” (photovoltaic) is used in this document. 1.1 Scope and object These supplementary requirements apply to fuse-links for protecting PV strings and PV arrays in equipment for circuits of nominal voltages up to 1 500 V d.c. Their rat

33、ed voltage may be up to 1 500 V d.c. NOTE 1 Such fuse-Iinks are commonly referred to as “PV fuse-links”. NOTE 2 In most cases, a part of the associated equipment serves the purpose of a fuse-base. Owing to the great variety of equipment, no general rules can be given; the suitability of the associat

34、ed equipment to serve as a fuse-base should be subject to agreement between the manufacturer and the user. However, if separate fuse-bases or fuse-holders are used, they should comply with the appropriate requirements of IEC 60269 series. NOTE 3 PV fuse-links protect down stream inverter components

35、such as capacitors or the discharge of capacitors back into the arrays or array wiring up to the rated breaking capacity. The object of these supplementary requirements is to establish the characteristics of PV fuse-links in such a way that they can be replaced by other fuse-links having the same ch

36、aracteristics, provided that their dimensions are identical. For this purpose, this standard refers in particular to a) the following characteristics of fuses: 1) their rated values; 2) their utilisation category; 3) their temperature rises in normal service; 4) their power dissipation; 4) their tim

37、e-current characteristics; 6) their breaking capacity; 7) their dimensions or size (if applicable). b) type tests for verification of the characteristics of fuses; c) the markings on fuses. 1.2 Normative references The following referenced documents are indispensable for the application of this docu
