摘要
Abstract
Direct-buried cables are often used as collection lines in photovoltaic power plants to collect and transport electrical energy.Accurate assessment of cable ampacity is the basis for cable selection in the design of photovoltaic power plants.This paper analyses the effects of soil moisture content,cable burial depth and soil boundary temperature on the YJLV22-26/35-3×400 three-core cable's ampacity according to the IEC 60287 thermal circuit analysis model,and proposes an approximate estimation formula for ampacity calculations.The study shows that reduced soil moisture content,increased cable burial depths and increased soil surface temperatures all decrease cable ampacity.Based on the conclusions of the study,measures to improve the ampacity of cables are proposed.关键词
