469-P5-HI-A20-E 469 系列中的电机保护继电器

电机保护功能包括转矩保护、过热保护、定子差动保护以及欠压和过压保护。继电器能够在检测到继电器内的负面状态时进行干预，快速评估严重性并使系统跳闸或在必要时采用其他解决方案（快速电机重启等）。这些方法有助于减少电机系统的整体停机时间，并延长电机寿命。

数据记录功能允许用户选择要测量的参数以及测量的间隔。这些参数可以按一秒到一小时的间隔进行趋势分析和绘制。其中一些参数包括电机负载、功率因数、扭矩、最热 RTD 和峰值视在功率。数据记录可以更深入地了解用户，增加对整个电机系统的了解。从长远来看，这减少了故障排除时间，并使用户能够更好地调整设定值配置。

The motor protection functions include torque protection, overheating protection, stator differential protection, and undervoltage and overvoltage protection. The relay can intervene upon detecting a negative state within the relay, quickly assess the severity and trip the system, or adopt other solutions if necessary (such as fast motor restart). These methods help reduce the overall downtime of the motor system and extend the lifespan of the motor.

The data recording function allows users to select the parameters to be measured and the measurement intervals. These parameters can be trended and plotted at intervals of one second to one hour. Some of these parameters include motor load, power factor, torque, hottest RTD, and peak apparent power. Data recording can provide a deeper understanding of users and increase understanding of the entire motor system. In the long run, this reduces troubleshooting time and allows users to better adjust set point configurations.
