摘要
以UniGear type ZS3.2型铠装式金属封闭开关设备为例,详细阐述了普通35kV开关设备经过科学的工频耐压和雷电冲击耐压试验,通过绝缘加强及元器件的修改,使之安全可靠地在高原地区使用。并缜密筛选出一套先进的技术改造方案,同时展望了其市场应用前景。
Taken UniGcar type ZS3.2 type armour metal enclose switchgear as an example, it was elaborated in detail that the ordinary 35 kV switchgear can be used safely in highland area through the tests of power frequency withstand voltage and lightning impulse withstand voltage, and the modification of insulation strengthening and components. And a set of advanced scheme of technical reformation was selected, at the same time, its prospect of application market was looked ahead.
