一种变压器中性点接地保护装置
摘要：
本实用新型公开了一种变压器中性点接地保护装置，中性点隔离开关的顶端通过连接母排连接避雷器的顶端，同时避雷器的顶端和间隙棒支架的顶端分别固定有放电间隙棒，中性点隔离开关的顶端通过接地线连接钢支架，间隙棒支架穿过互感器的内部空间。该装置能在变压器中性点出现雷电过电压、操作过电压和暂时过电压时起保护作用，具有占地面积更少，组装方式灵活、运行安全可靠的特点。
摘要（英）：

The utility model discloses a neutral point grounding protective device of a transformer. The top end of a neutral point disconnecting switch is connected to the top end of a lightning arrester through a connecting busbar; discharge gap rods are fixed at the top end of the lightning arrester and the top end of a gap rod bracket; the top end of the neutral point disconnecting switch is connected with a steel bracket through a grounding wire; and the gap rod bracket penetrates the interior space of a mutual inductor. The device can play a role of protection when lightning overvoltage, switching overvoltage or temporary overvoltage occurs, and has the characteristics of lesser occupied area, flexile assembly manner, and safe and reliable operation.
