保护放电器

The protective mode is fused with the gap units of distributed feeder protection easily, and does without disposing appropriative devices for the selection grounded feeders and its software.
该保护方式容易融于分布式馈线保护间隔单元中，不需配置监控系统选线模块或专用选线装置。
Based on the configuration analysis of neutral point for 110 kV graded insulation transformer, this paper suggested that protective gap should not be installed at neutral point of 110 kV transformer where no power plant is available at low voltage coils.
对110kV分级绝缘变压器中性点保护间隙配置进行了分析，认为低压侧无地方电源介入的110kV变电所内的主变压器中性点不应加装棒间隙。
Through the coordination test of discharge characteristics for protective gap and working gap, it is proved that adding protective gap can not only improve the safety for live line work and can reduce the tower size efficiently.
通过保护间隙与工作间隙放电特性的配合试验，证明加装保护间隙不仅可提高带电作业的安全性，而且能有效地减小塔头尺寸。
