269PLUS-DO-211-120N-120VAC 系统的目的是作为一层保护

【产品详情】

269PLUS-DO-211-120N-120VAC是GE Multilin 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一层保护，保护三相交流电动机免受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120vac。该系统使用电阻热检测器(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。

该保护系统使用EnerVista Launchpad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还提供了一个工具包，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能力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负载温度。此外，面板的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输入和屏幕的对比度刻度盘。

【英文介绍】

269PLUS-DO-211-120N-120VAC is a motor protection system in the 269 Plus Motor Management Relay Series by GE Multilin. The purpose of this system is to act as a layer of protection for 3-phase AC electric motors from damage due to temperature and electrical hazards. The operating voltage for the controller on this protection system is 120 VAC. The system uses resistance thermal detectors (RTD) to determine thermal conditions while current transformers (CTs) are used to determine electrical conditions. The system uses 120 Ohm nickel based RTDs.

The protection system uses the EnerVista Launchpad software package to run its internal needs, including setup and support. The software can communicate to external devices using a variety of methods including serial, ethernet, and modem. Configuration files can also be created externally and transmitted to the protection system. EnerVista also comes available with a toolkit, which includes GE Multilin Drivers as well as Automatic Event and Waveform Retrieval abilities.

The back of the system panel contains a variety of inputs and outputs that are needed to fully utilize the protection capabilities. There are 10 RTD inputs on the back of the panel which are divided into 3 sections. RTD 1-3 and 4-6 inputs are typically used for stator winding protection. RTD 7-10 are typically used for monitoring ambient temperature as well as motor and load bearing temperature. Additionally, the back of the panel contains the control power inputs and the four output relays. There are also the phase and ground CT inputs and a contrast dial for the screen.
