1MRK008514-CB 间隔控制单元 能够发出装置异常信号

1MRK008514-CB间隔控制单元是电力系统中的一个重要设备，具有以下功能和特点：设置当地/远动转换开关，用于在这两种控制模式之间进行转换。信号/遥信功能：这包括本间隔的开关设备的位置信号、柜内设备运行的事故信号、预告信号、保护动作信号、操作信息、自检信息等。此外，该单元还可以接收外部输入接点信号，并在液晶显示器上显示这些信号内容，同时向通信控制器转发。测量表计/遥测功能：通过对电流、电压的交流采样，给出电流、电压、功率测量值。对电度量，既可以采用计算方式，也可以采用变送器方式测出。所有测量值都应在间隔控制单元显示，同时向通信控制器转发，所有测量精度不低于1级。在线自检功能：装置中的任一元件损坏不应造成保护误动。在装置故障的情况下，应能够发出装置异常信号，所有自检信号应向通信控制器转发。电源故障应对能力：在外部电源故障或失电时，装置的设定参数及状态数据、实时时钟信号及其它主要动作信号不应丢失。当外部电源恢复时，装置应能恢复其正常功能，重新正确显示并输出。总的来说，1MRK008514-CB间隔控制单元是电力系统中的重要组成部分，它负责监控和控制电力系统中的特定间隔（如一个断路器和一个相关的设备组合），以确保电力系统的安全和稳定运行。

REC650 1MRK008514-CB

The 1MRK008514-CB interval control unit is an important equipment in the power system, with the following functions and characteristics: setting local/remote conversion switches for switching between these two control modes. Signal/remote signaling function: This includes position signals of the switchgear in this interval, accident signals of equipment operation in the cabinet, warning signals, protection action signals, operation information, self inspection information, etc. In addition, the unit can also receive external input contact signals and display these signal contents on the LCD display, while forwarding them to the communication controller. Measurement meter/telemetry function: By sampling AC current and voltage, provide current, voltage, and power measurement values. For electrical measurement, both calculation and transmitter methods can be used to measure it. All measured values should be displayed on the interval control unit and forwarded to the communication controller, with a measurement accuracy of no less than level 1. Online self check function: Any damage to any component in the device should not cause protection misoperation. In the event of device failure, it should be possible to send out device abnormal signals, and all self check signals should be forwarded to the communication controller. Power failure response capability: In the event of an external power failure or loss of power, the device’s set parameters and status data, real-time clock signals, and other major action signals should not be lost. When the external power supply is restored, the device should be able to restore its normal function, correctly display and output again. Overall, the 1MRK008514-CB interval control unit is an important component of the power system, responsible for monitoring and controlling specific intervals in the power system (such as a circuit breaker and related equipment combination) to ensure the safe and stable operation of the power system.
