On the one hand, the streetlight system has brought great convenience to pedestrians at night and improved the quality of the city, but on the other hand, it has also brought many safety hazards. Incidents such as live light poles, box seat leakage, and streetlight cable injuries have occurred from time to time, which has attracted widespread attention.

Analysis of the causes of electric shock in street lamps

The power supply voltage for street lamps is 380/220V low-voltage cable power supply system. The power supply is generally sourced from the nearest public transformer or street lamp dedicated transformer, and is distributed through the street lamp control box or box transformer using three-phase four (five) line low-voltage cables. The power supply radius of each street lamp control box is less than 500 meters. The main causes of electric shock accidents in the streetlight system are as follows:

(1) Failure to comply with operating procedures resulted in direct contact between the human body of the streetlight maintenance personnel and the live parts.

(2) In the maintenance of streetlight facilities, inadequate safety organizational and technical measures, incorrect wiring, and electric shock accidents have occurred.

(3) Due to improper management or aging of streetlight facilities, insulation damage may occur, resulting in electrical leakage. People may come into contact with the leaking streetlights and control boxes.

(4) Other accidental factors, such as lightning strikes on streetlights, can cause personal injury to those in contact or around the streetlights.

Smart and Safe Electricity Solution for Electric Protection Street Lights

The front-end of smart and safe electricity monitoring mainly consists of a monitoring controller, transmission module, residual current transformer, temperature sensor, and current transformer. It monitors the load current, voltage, temperature, residual current, overload, and phase loss of electrical circuits in real time. The feedback information from the electrical circuit is transmitted to the cloud platform through the transmission module network, and pushed to relevant management personnel through APP, SMS, and other methods.

According to the electricity consumption characteristics of street lamp posts, a smart electricity monitoring system is installed in the street lamp distribution control box to monitor the real-time status of the electrical circuit. Anti electric shock protectors are installed in the distribution lines of the lamp posts to ensure that electric shock does not harm people and that water immersion does not cause leakage.

The problem solved by the smart electricity solution for street lamps

1. Real time monitoring of the electrical status of street lamp distribution, the smart and safe electricity system can track and analyze data on current, voltage, leakage current, and wire temperature 24 hours a day without interruption. Real time monitoring of circuits, strict control and investigation of safety hazards such as abnormal cable temperature, short circuit, overload, overvoltage, undervoltage, and leakage in electrical circuits and equipment, timely warning, and timely handling of line hazards.

2. Provided a safe working environment for street lamp maintenance personnel.

3. Reduce personnel electric shock accidents caused by thunderstorm weather or aging power lines.

The Necessity of Installing Smart and Safe Electricity System for Street Lights

By installing a smart and safe electricity system on the electrical facilities of street lamps, the real-time status of the street lamp power distribution system can be well monitored, and electrical safety hazards can be detected and dealt with in a timely manner. In particular, the application of anti electric shock protectors can greatly prevent harm to people caused by electric shock accidents in the street lamp system, providing a reliable and safe lighting environment for cities and the general public.
