Intelligent Terminal for Ring Cabinet

Product Overview

Intelligent terminal equipment of ring network cabinet, on the basis of not changing the structure and accessories of ring network cabinet, utilizing the existing space of ring network cabinet, through reasonable design and collocation, joining the sensor-type high-voltage energy measurement method, through the fusion of one and two devices, so as to make the ring network cabinet have the intelligent measurement, metering, transmission and control function of high-voltage electric power information, and to realize the real-time monitoring of the status of the ring network cabinet to meet the intelligent communication needs of "self-healing", "refined line loss management", "integration of marketing, operation and maintenance, and dispatching". It realizes real-time monitoring of the status of the ring main unit and meets the intelligent communication requirements of "self-healing", "fine line loss management" and "integration of marketing, operation and maintenance and dispatching". The device greatly improves metering accuracy, safety and reliability, and ease of installation, and is the preferred product for high-voltage power metering and lean line loss assessment.
