GE Multilin 369-HI-R-M-0-0-0-E | 369 Motor Management Relay电机管理继电器

369-HI-0-M-0-0-E is a motor management relay that is manufactured by GE Multilin. The control power is 50-300 VDC / 40-265 VAC. There are no optional RTD inputs on this relay. This unit includes an optional metering package. There is no optional fiber optic port. This relay provides protection and monitoring for 3-phase motors and their associated systems. The 369 can ‘learn’ individual motor parameters and adapt itself to individual applications. In order to improve the protective capabilities of the relay, the user may adjust the motor inrush current, the cooling rates, and/or the acceleration time. If you have any questions about this motor management relay or the associated series or manufacturer, please contact AX Control.

The setpoints key allows the user to navigate through the programmable parameters page headers. The actual values key allows the user to navigate through the measured parameters page headers. The page up and down keys can be used to scroll through page headers for both actual values and setpoints. The line up and down keys can be used to scroll through the subheadings. The value up and down keys allow the user to scroll through variables in the setpoint programming mode. The reset key allows the user to reset a trip or latched alarm. The enter key can enter the subgroups or store altered setpoint values. The clear key can exit the subgroups or return an altered setpoint to its original value. The help key may be pressed at any time for context sensitive help messages.

继电保护装置就是指能反应电力系统中电气元件发生故障或者不正常运行状态，并动作于断路器跳闸或发出信号的一种自动装置。

它保护的是各种故障（短路、电压大大降低、系统震荡等）和不正常运行状态（过负荷、频率降低、低电压等），因为这些故障和不正常运行状态，都可能在电力系统中引起事故。
各种原理的保护，通常可以由一个或者若干个继电器连接在一起组成保护装置来实现。就一般情况而言，整套继电保护装置是由测量部分、逻辑部分和执行部分组成的。因此你所说的保护装置也就是指各种继电器，例如：电流断路器、抗阻继电器、输电线纵联差动保护、变压器的纵差动保护等。

继电保护装置的作用

反应电气设备的不正常工作情况，并根据不正常工作情况和设备运行维护条件的不同发出信号，提示值班员迅速采取措施，使之尽快恢复正常，或由装置自动地进行调整，或将那些继续运行会引起事故的电气设备予以切除。反应不正常工作情况的继电保护装置允许带一定的延时动作。

实现电力系统的自动化和远程操作，以及工业生产的自动控制。如:自动重合闸、备用电源自动投入、遥控、遥测等。
