引言

GB/T48012《光伏發(fā)電系統(tǒng)用功率轉(zhuǎn)換設(shè)備安全性》是光伏發(fā)電系統(tǒng)用功率轉(zhuǎn)換設(shè)備安全相關(guān)要

求的通用標(biāo)準(zhǔn)。GB/T48012擬由三個(gè)部分構(gòu)成。

——第1部分：通用要求。目的在于規(guī)定功率轉(zhuǎn)換設(shè)備應(yīng)符合的一般要求，包括但不限于產(chǎn)品的

環(huán)境要求、危險(xiǎn)防護(hù)、物理性能要求、零部件、安全功能的軟件和電路等方面的要求。

——第2部分：逆變器的特定要求。目的在于規(guī)定并網(wǎng)或獨(dú)立逆變器相關(guān)要求。

——第3部分：與光伏部件連接的電子器件特定要求。目的在于規(guī)定電子元件和光伏元件或光伏

組件組成的產(chǎn)品。

本文件是GB/T48012《光伏發(fā)電系統(tǒng)用功率轉(zhuǎn)換設(shè)備安全性》的第2部分，規(guī)定了光伏并網(wǎng)型、多

模式型和獨(dú)立型逆變器的安全要求。該設(shè)備具有潛在危險(xiǎn)的輸入電源和輸出電路、內(nèi)部部件以及特性

和功能，本文件對第1部分中給出的安全要求作出了不同或額外的規(guī)定。
