摘要
介绍了光伏系统由太阳能板、直流汇流箱、直流配电柜、逆变器、交流配电柜等组成。DC 1 000 V光伏系统中一般使用4P单断点断路器,其存在温升问题。DC1 500 V光伏系统加大了断路器开距和灭弧室容量。最后介绍了国内光伏标准制定情况。
This paper introduced that photovoltaic system consists of solar panel,DC junction box,DC distribution cabinet,inverter,AC distribution cabinet,etc.DC 1 000 V PV system is a commonly used system.It generally uses 4P circuit breaker of single breakpoint,and has a temperature rise problem in the series.DC 1 500 V PV system is a newly-developing system,it increases the opening distance and arc control device capacity.Finally,the paper introduced the domestic photovoltaic standard.
