什么是光伏接线盒?光伏接线盒的分类和构成部分

幻启太阳能科技 10/13/2021

光伏接线盒是介于太阳能电池组件构成的太阳能电池方阵和太阳能充电控制装置之间的连接装置,其主要作用是连接和保护太阳能光伏组件,将太阳能电池产生的电力与外部线路连接,传导光伏组件所产生的电流。

一、光伏接线盒的分类

太阳能光伏接线盒分晶体硅接线盒、非晶硅接线盒、幕墙接线盒。

二、光伏接线盒的构成

太阳能光伏接线盒由盒体、线缆及连接器三部分构成。

盒体:包括盒底(含铜接线柱或塑料接线柱)、盒盖、二极管;

线缆:分为1.5MM2、2.5MM2、4MM2及6MM2等这几种常用的线缆;

连接器:分为MC3与MC4两种;

二极管型号:10A10、10SQ050、12SQ045、PV1545、PV1645、SR20200等

二极管封装有两种:R-6 SR 263;

作为光伏组件的配套产品,光伏接线盒所占成本不及电池成本十分之一,但却是决定光伏组件最终能否正常工作的重要部件。如果接线盒选取不当,可使电池板烧毁从而影响整个光伏系统性能。
