239-RTD-AN 保护继电器概述

239-RTD-AN保护继电器是由通用电气Multilin生产的电机保护继电器，主要用于保护三相交流电机，为电机在某些恶劣条件下提供·面保护。

239-RTD-AN保护继电器的特点

239-RTD-AN 可编程功能

RTD类型可编程

有镍、铂或铜三种可编程RTD类型。

输出参数可编程

带有可编程输出参数，其mA模拟输出有0-1mA、0-20mA和4-20mA三种选择。

可调整RTD1、RTD2和RTD3的相电流温度、改变热容量以及改变满载的百分比等参数。

239-RTD-AN 多种保护功能

常见故障保护

提供断路器故障保护、过载警告保护、接地故障保护和转子锁定保护等多种保护功能。

还能防止欠流、短路等故障，例如可以检测关闭的排放阀或吸力损失等机械故障。

239-RTD-AN 启动保护相关

有启动保护功能，并且当不需要启动保护时可以在继电器上禁用。如果继电器上的设定值设置为“是”，则模型将直接进入过载曲线，并将采用运行条件来保护连接的负载模型。此特定设定点也可与开关输入一起使用，如果希望在连接开关输入闭合时启动保护失效，则·须将禁用启动设置为yes。

机械堵塞保护

机械堵塞功能主要用于保护连接的设备，如齿轮箱、锯、压缩机和泵等，通常建议在设备运行期间转子锁定的情况下立即跳闸。

239-RTD-AN 显示与指示功能

显示屏

前面板包括一个40个字符的LCD显示屏，用于查看状态消息、故障条件和设定值。

状态指示灯

装置有六个LED状态指示灯，可直观显示相关状态。

键盘

面板还包括一个防尘、防溅的键盘，并且当钥匙不使用时，可以使用保护门来盖住钥匙。

239-RTD-AN 保护继电器的模拟输出

输出类型

具有可选的单路可编程模拟输出，并且是单个隔离模拟输出。

输出范围

可在4-20、0-1或0-20三种不同的毫安范围内工作，用户可根据需求选择模拟输出范围。

239-RTD-AN-H 型号（239-RTD-AN的扩展型号）

恶劣环境涂层

239-RTD-AN-H是239-RTD-AN型号的扩展，添加了带有H订购代码的恶劣环境涂层。

相关软件

具有239PCWindows软件。

Overview of 239-RTD-AN protective relay

239-RTD-AN protection relay is a motor protection relay produced by General Electric Multilin. It is mainly used to protect three-phase AC motors and provide comprehensive protection for the motor under certain harsh conditions.

 Characteristics of 239-RTD-AN protective relay

239-RTD-AN Programmable functions

RTD type programmable

Programmable RTD types are available in nickel, platinum or copper.

Programmable output parameters

With programmable output parameters, its mA analog output has three options: 0-1mA, 0-20mA and 4-20mA.

Parameters such as the phase current temperature of RTD1, RTD2 and RTD3 can be adjusted, the heat capacity can be changed, and the percentage of full load can be changed.

239-RTD-AN  Multiple protection functions

239-RTD-AN Common fault protection

Provides multiple protection functions such as circuit breaker fault protection, overload warning protection, ground fault protection and rotor lock protection.

It also prevents faults such as undercurrent and short circuits, and can detect mechanical faults such as closed discharge valves or loss of suction, for example.

239-RTD-AN Startup protection related

There is a start-up protection function and can be disabled on the relay when start-up protection is not required. If the setpoint on the relay is set to "Yes", the model will go directly to the overload curve and the operating conditions will be applied to protect the connected load model. This specific setpoint can also be used with switch inputs, if you want the start protection to fail when the connected switch input is closed, disable start must be set to yes.

239-RTD-AN Mechanical jam protection

The mechanical blocking function is mainly used to protect connected equipment such as gearboxes, saws, compressors and pumps, etc. It is usually recommended to trip immediately in the event of rotor locking during equipment operation.

239-RTD-AN Display and indication functions

239-RTD-AN Display

The front panel includes a 40-character LCD display for viewing status messages, fault conditions and setpoints.

239-RTD-AN status light

The device has six LED status indicators to visually display relevant status.

keyboard

The panel also includes a dust- and splash-proof keypad, and a protective door can be used to cover the keys when they are not in use.

Analog output of 239-RTD-AN protective relay

239-RTD-AN Output type

Features an optional single programmable analog output and is a single isolated analog output.

239-RTD-AN Output range

It can work in three different mA ranges of 4-20, 0-1 or 0-20. Users can select the analog output range according to their needs.

239-RTD-AN-H model (extended model of 239-RTD-AN)

Harsh environment coating

239-RTD-AN-H is an extension of model 239-RTD-AN, adding a harsh environment coating with H ordering code.
