产品描述

269PLUS-DO-211-120N-120VAC是GE Multilin的269 Plus电机管理继电器系列中的电机保护系统。 该系统的目的是作为三相交流电动机的保护层，防止因温度和电气危险而损坏。该保护系统上控制器的工作电压为 3 VAC。该系统使用电阻热探测器（RTD）来确定热条件，而电流互感器（CT）用于确定电气条件。该系统使用 120 欧姆镍基 RTD。

保护系统使用 EnerVista 快速启动板软件包来运行其内部需求，包括设置和支持。该软件可以使用多种方法与外部设备通信，包括串行、以太网和调制解调器。配置文件也可以在外部创建并传输到保护系统。EnerVista还附带一个工具包，其中包括GE Multilin驱动程序以及自动事件和波形检索功能。

系统面板的背面包含充分利用保护功能所需的各种输入和输出。面板背面有 10 个 RTD 输入，分为 3 个部分。RTD 1-3 和 4-6 输入通常用于定子绕组保护。RTD 7-10 通常用于监测环境温度以及电机和轴承温度。此外，面板背面包含控制电源输入和四个输出继电器。还有相位和接地CT输入以及屏幕的对比拨盘。

Product description

The 269PLUS-DO-211-120N-120VAC is a motor protection system in GE Multilin's 269 Plus motor management relay family. The purpose of the system is to act as a protective layer for three-phase AC motors against damage due to temperature and electrical hazards. The operating voltage of the controller on the protection system is 3 VAC. The system uses a resistance thermal detector (RTD) to determine thermal conditions, while a current transformer (CT) is used to determine electrical conditions. The system uses 120 ohm nickel-based RTD.

The protection system uses the EnerVista Quick-Launch Board package to run its internal requirements, including setup and support. The software can communicate with external devices using multiple methods, including serial, Ethernet, and modems. Configuration files can also be created externally and transferred to a protection system. EnerVista also comes with a toolkit that includes GE Multilin drivers and automatic event and waveform retrieval capabilities.

The back of the system panel contains the various inputs and outputs needed to take full advantage of the protection features. There are 10 RTD inputs on the back of the panel, divided into 3 sections. RTD 1-3 and 4-6 inputs are typically used for stator winding protection. RTD 7-10 is commonly used to monitor ambient temperatures as well as motor and bearing temperatures. In addition, the back of the panel contains control power inputs and four output relays. There are also phase and ground CT inputs and contrast dials for the screen.
