Intelligent Ring Main Unit Solution Overview

Within RolinkPower™ intelligent ring main unit system, Rolink adopts IoT technology and on-line/off-line service to realize smart power theory of ‘Unattended but manned’ for distribution power system. This kind of RMU is known for small structure and environmental protection, integrating control and data service, deeply combining primary equipment and secondary control. Through intelligent gateway, we carry out collection, analysis and treatment on data, implement data storage on our cloud platform, adopt edge computing and big data analysis to judge operation and status of equipment. Our users can get information of equipment operation in real-time through App on mobile phones and computers. Our data center does an all-round monitoring all day and all night. Meanwhile, a professional team can work together to provide installation, data access, data analysis and alarms on the terminal equipment, and offer one-stop after-sale service of operation and failure report. Rolink RMU series includes SF6 switchgear, solid switchgear, eco-friendly switchgear (gas). They are applied in the distribution power system of high reliability, like commercial centers, industrial areas, airpots, electric railways, super highways and so on. Get free solution

Industrial pain points The current refinement of production in the industry places higher demands on power supply and equipment control.

Poor integration of primary and secondary Complex structure. Demanding technology. High maintenance cost. Frequent failure.

Low protection level of system The equipment volume is too large and occupies too much space, but the urban layout is limited.

Lack of fault prediction It’s of high operation risk and short circuit danger. It needs additional protection.

Lack of health management Lack of intelligence. Unable to control remotely. Low management efficiency.

Application value

Safety and reliability Rolink fully-sealed insulated RMU adopts a new generation of integrated mechanism switch assembly with PCT international patent. The interlock is simple and reliable. The cable compartment door is of maze structure with arc resistance, which can avoid personal injury. The electrical components are front-loaded for easy maintenance.

Intelligence As for state grid, Rolink fully-sealed insulated RMUs conform to standards and requirements of State Grid of China and China Southern Power Grid, two national grid corporations in China. Rolinks RMUs adopt distributed DTU of primary and secondary integration. As for users, intelligent control unit, key parameter sensor and miniaturized intelligent gateway constitute intelligent RMU. We realize remote monitoring, operation and maintenance through ISE platform.

Smart power RISE+ intelligent RMU solution covers RMU itself, its network, and all-round monitoring on its environment (distribution rooms/box substations). This solution creates intelligent power use networks for railway stations, industrial parks and commercial centers to enjoy the experience of safety, efficiency, low-carbon and intelligence.

A digital way out to a green future.

The intelligent energy management system helps users improve management efficiency and achieve the energy-saving and emission reduction target.
