摘要
比较全面地分析了国内10 kV配电网中主流类型开关设备的20 kV升压改造情况,对移开式开关柜、固定式开关柜和环网柜提出了采用内部结构优化的升压改造方法,为将来10 kV配网逐渐升压至20 kV电压等级的过程,提出了经济、可靠的开关设备升压改造方案。研究表明,在确保柜体安全性和可靠性的前提下,通过采用内部结构优化改造的方法可以使目前国内大部分种类的开关设备达到20 kV运行要求。
The voltage-rise reforming of domestic switchgear from 10 kV to 20 kV is comprehensively analyzed and a reliable and economical solution of voltage-raise reforming is provided for the withdrawable switchgear,fixed switchgear and ring-net switchgear,which adopts the optimization of internal structure. Study shows that most of domestic 10 kV switchgears can be upgraded to 20 kV voltage level by means of internal structure optimization on the premise that the safety and reliability of cabinet are assured.
