太阳辐射下的GIS断路器温度分布研究
Study on Temperature Distribution of GIS Circuit Breaker Under Solar Radiation
摘要
Abstract
Gas insulated switchgear(GIS)is an important electrical equipment in power transmission and distribu-tion system.Its working stability will directly affect safe and stable operation of power grid.Not only the internal flow and fault heating of the switchgear will lead to the temperature rise of the enclosure,but also the external solar radiation will affect the temperature distribution of the enclosure and cause interference to the fault detection sys-tem based on temperature.The temperature field distribution of GIS circuit breakers under solar radiation is particu-larly studied particularly by using the exploration method combining finite element simulation,prototype test and field test,and comprehensively considering such factors as skin effect,eddy current effect,gravity effect,convection heat dissipation and radiation heat dissipation.The results show that the solar radiation will greatly affect the tem-perature rise of GIS enclosure,and it will change with the change of direct sunlight angle and intensity.When study-ing the temperature rise of outdoor GIS equipment,the influence of solar radiation on the temperature field shall be considered.The setting of sensor position and temperature rise value criteria shall be corrected in accordance with the solar radiation level.The results can provide some reference for studying the temperature field distribution of outdoor GIS equipment under solar radiation.关键词
