Littelfuse AF0100弧闪继电器

Littelfuse AF0100弧闪继电器通过使用光传感器快速检测断路器中的电弧和跳闸来限制弧闪破坏。 Littelfuse AF0100可监控传感器、输入和跳闸线圈电压，以确保在运行过程中提供故障保护。 这些基于微处理器的保护继电器设有二次侧固态电路，可在分流跳闸模式下提供冗余跳闸路径。AF0100不直接连接到系统，因此可用于在任何电压（交流或直流）下工作的电气系统。 AF0100的尺寸极小，可安装在任何开关柜、变压器室、发电机控制面板或电机控制中心中。 AF0100可接受PGA-LS10（点）、PGA-LS20（光纤）和PGA-LS30（光纤）光学传感器。 这些传感器被设计为具有较宽的检测角度，并为弧闪提供恰当的灵敏度。

The small size of the AF0100 allows installation in any switchgear cubicle, transformer compartment, generator control panel, or motor control center bucket. AF0100 accepts PGA-LS10 (point), PGA-LS20 (fiber), and PGA-LS30 (fiber) optical sensors. These sensors have been designed to have a wide detection angle and provide the correct sensitivity for an arc flash.

特性

  • Compact: Fits into a wide range of arc-flash applications
  • Two optical sensor types: Point sensors or fiberoptic sensors can be used in any combination for coverage flexibility
  • Dual sensor inputs: One relay can monitor two arc-flash sensors
  • Adjustable light sensitivity: Allows for operation in bright environments and maximum sensitivity in dark environments
  • Discrete wire networking: User can interconnect multiple AF0100 or AF0500 units to form a system
  • Fail-safe system: Continuous monitoring of optical sensors and inputs ensures protection
  • USB interface: Easy-to-use configuration software with no drivers or software installation
  • Unit health: Ensures continuous protection with self-diagnostic and remote unit-healthy indication
  • LED Indication: Trip and sensor status indication both on relay and sensors
