GNI负载断开与故障中断开关设备

G&W Electric型号GNI垫板开关具备负载断开和故障中断功能，双向均可见断路和集成接地位置。这样就不需要处理任何高压连接来接地电缆。高压连接处位于开关操作员的另一侧，以进一步隔离操作员免受高压影响。故障断路器在完全密封、死前端的设备中提供电子控制、可复位的超流保护。这些开关设计用于电压最高38kV、900A负载断路和连续电流的三相系统，具有12.5kA、20kA和25kA对称故障中断额定值。GNI是较为多功能的配置之一，因为它可以订购前置可访问的开关操作员和套管，也可以选择前置操作员和后置套管。

GNI垫装开关设计符合IEEE C37.72、C37.74和C37.60标准，具备负载断开和故障中断能力，是我们先进 开关 设备解决方案的关键组成部分，确保安全可靠的电力分配。垫装外壳设计并测试符合IEEE C57.12.28和C57.12.29标准。

特色与优势

  • 建设 – 可提供前置开关操作器和衬套，或前置操作器和后置衬套。拱顶结构还可提供顶部或底部衬套，或顶部触及操作器和衬套。

  • 故障中断 三相故障中断，电流最高达25kA，可选择工业曲线，包括熔断器仿真曲线。

  • 电压感应 – 所有方式均配备集成电压感应功能，可配合电压指示面板测定同相状态，或与继电器配合使用，精度最高可达1%。

  • 可见断裂 – 所有航行都配备可见断裂，可查看开启、关闭和地面位置。

  • 地面位置 – 所有方向均集成接地位置，避免使用高压元件来接地电缆。

  • 自动化 – 适用于电动机自动化，配备便携式或永久安装的电机和控制装置。G&W Electric的编程和箱体制造提供了多种继电器，如SEL、ABB和GE。柜体可订购为低压外壳，用于安装垫、底座或IP68级潜水器，用于穹顶安装开关设备。提供自动源传输、保护或激光器定制解决方案的编程。
