Smart City Electricity Management Platform

If prevention is possible, why ignore it?

The smart city electricity safety solution is based on the Internet of Things, big data, and cloud computing technologies. Through advanced cloud platforms (intelligent electricity management platform) and smart terminals (intelligent fault arc circuit breakers), it realizes big data analysis of multiple electrical safety hazards such as leakage, overload, short circuit, and abnormal fault arc, accurately locates the location of electrical fire hazards, and achieves safety warning. In addition, by detecting user power parameters through fault arc intelligent circuit breakers and visualizing user power consumption through an intelligent power management platform, decision support is provided for users to save electricity.

The solution has the following characteristics:

1.24-hour security of electricity usage

When there is an abnormal electricity usage (overload, short circuit, leakage, arc fault) on site, the platform issues an abnormal electricity usage alarm and actively pushes the alarm to the user. Different alarm notifications (email, SMS, phone) are provided to the user according to different dangerous situations, achieving 24-hour protection of user electricity safety.

2. Electrical Fire Detective

The main culprit causing electrical fires is fault arcs, and fault arc detection and fault data analysis can serve as a great detective for electrical fires. Based on the user's historical fault time and frequency data, it can analyze the fire hazards of the user's electricity consumption, provide reasonable solutions to eliminate and solve the hazards according to the hazard level, eliminate electrical fires in the bud, and ensure the personal and property safety of users.

3. Visualization of battery usage

The solution provides real-time electricity consumption monitoring charts, historical electricity consumption and cost statistics tables. Users can view their household electricity consumption like checking WeChat steps, and can view the ranking and proportion of their daily electricity consumption in the country. By horizontally comparing the electricity consumption expenses of various households, users can have a more intuitive and visible understanding of their own electricity consumption.

4. Effective energy-saving methods

Users can manage electricity uniformly based on the electricity safety management platform. By accurately and reliably measuring electricity data, they can allocate loads reasonably, achieve optimized operation, effectively save electricity, and have records of peak and off peak electricity consumption, providing data basis for reasonable electricity management.

Application Background

In recent years, electrical fires have occurred frequently in China, causing significant casualties and property damage. According to statistics, from 2011 to 2016, there were 524000 electrical fires in China, resulting in 3261 deaths and 2063 injuries, with a direct economic loss of over 9.2 billion yuan. Electrical fires accounted for more than 30% of the total number of fires and casualties in the country; Among them, there were 17 major electrical fires, accounting for 70% of the total number of major fires. These accidents have exposed prominent problems in the production quality, circulation and sales of electrical products, electrical design and construction of construction projects, as well as the use, maintenance and management of electrical products and their circuits.

After investigation, it was found that the main causes of electrical fires are as follows:

1.Short circuits of "series arc" or "parallel arc" caused by poor contact or insulation damage of electrical circuits (mostly due to carbonization caused by circuit aging);

2.Grounding (arc) faults caused by insulation damage to the ground in electrical circuits;

3.Abnormal temperature rise caused by poor electrical circuit contact, improper arrangement of electrical equipment, and overload. Among them, the concealment and difficulty in detecting arcing short circuits have become the primary issue in electrical fire prevention. When the temperature of the arc exceeds 5500 ℃, the heat particles emitted by the high-strength thermoelectric arc can accumulate over time and easily ignite the insulation layer materials around the circuit, causing electrical fires.

At present, traditional electrical protection devices such as circuit breakers, fuses, and residual current protectors can only provide protection against overload, short circuit, and ground fault currents; For fault arcs, due to the fact that the current value of series fault arcs is less than the rated current of the circuit, the current value of parallel fault arcs may also be less than the rated current in most cases. Therefore, traditional thermal magnetic systems cannot provide effective fault arc protection and cannot meet the requirements of preventing electrical fires, resulting in electrical protection loopholes.

The fault arc intelligent circuit breaker in the solution can replace the circuit breaker to achieve uninterrupted data tracking and statistical analysis of the main factors that cause electrical fires (leakage, overload, wire temperature, residual current, fault arc), and timely push various hidden danger information discovered to users, guiding them to conduct timely investigation and treatment, achieving the goal of eliminating potential electrical fire safety hazards and preventing them in advance.
