Smart and Safe Electricity Use – Street Lamp Solution http://www.zjchen8602.cn/en/case3.html http://www.zjchen8602.cn/en/case3.html#respond Wed, 28 Aug 2024 12:15:09 +0000 https://www.qbkg.com/?p=804 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.

Electric protection street light solution

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.

Smart and Safe Electricity Use – Charging Pile Solution http://www.zjchen8602.cn/en/case2.html http://www.zjchen8602.cn/en/case2.html#respond Wed, 28 Aug 2024 12:14:32 +0000 https://www.qbkg.com/?p=803 With the increasing global emphasis on environmental protection, new energy vehicles have become the future development trend. As the core infrastructure of new energy vehicles, the intelligent solution of charging piles is crucial for promoting the popularization and development of new energy vehicles. Improving user experience and meeting the rapidly growing demand for electric vehicle charging through intelligent and efficient charging services has become a current industry development trend.

With the increasing global emphasis on environmental protection, new energy vehicles have become the future development trend. As the core infrastructure of new energy vehicles, the intelligent solution of charging piles is crucial for promoting the popularization and development of new energy vehicles. Improving user experience and meeting the rapidly growing demand for electric vehicle charging through intelligent and efficient charging services has become a current industry development trend.
Electric vehicle charging fires are frequent and frequent

With the increasing number of new energy vehicles and electric vehicles, related fire accidents are also constantly increasing, seriously threatening the safety of people’s lives and property.

According to the statistics of the fire department, more than 80% of electric vehicle fires occur during the charging process. There are over 2000 electric vehicle charging fires every year, resulting in more than 1000 casualties and economic losses exceeding 300 million yuan.
Overcharging is the leader of charging fires. Malfunctions and mismatches in batteries and chargers, aging wiring, charging at home, and pulling wires privately are all causes of charging safety hazards.

The lack of a unified comprehensive management platform, the absence of visual data and analysis tools, the repeated prohibition of unauthorized charging behavior, and insufficient efforts to identify and manage hidden dangers have become pain points in electric vehicle fire management.

The smart charging station solution has advantages such as automatic power-off when fully charged, monitoring of poor contact of charging lines, arc extinguishing charging short circuit protection, APP property supervision and 24-hour service center supervision, automatic identification of charging items, abnormal power-off monitoring of charging batteries, and a more user-friendly charging mode.

The smart charging pile solution adopts different data transmission schemes according to the different scenarios of charging piles/stations, meeting the application needs of different users and scenarios, making electric vehicle charging more intelligent, scientific, visual, and safe, and helping regulatory authorities to strengthen the entire safety responsibility chain.

 

The IoT smart cloud platform can achieve multiple security guarantees such as online monitoring, data collection, timed control, remote control, short circuit protection, leakage protection, fault warning and alarm, reducing the risk of insufficient maintenance of charging equipment and charging fire accidents, ensuring charging speed and efficiency, no longer worrying about accidents during charging, and enjoying the pleasure of driving with peace of mind.

Apartment smart and safe electricity transformation project http://www.zjchen8602.cn/en/case1.html http://www.zjchen8602.cn/en/case1.html#respond Wed, 28 Aug 2024 12:13:41 +0000 https://www.qbkg.com/?p=801 Hidden danger investigation:

1. If the power is not unplugged when people leave, the power is not turned off when people leave, and the electrical appliances are in a charging state for a long time, it will cause the electrical equipment to overheat or short-circuit and cause fire.

2. The wires are messy and privately pulled and connected. It is very easy to cause electric shock, leakage accidents, and even fire.

3. The use of high-power electrical appliances or homemade electrical equipment: water boiling rods, electric cups, rice cookers, electric heating mattresses, heaters, electric stoves and other electrical appliances are all high-power electrical appliances. The use of such electrical appliances is prone to fire, electric shock, mechanical injuries and other safety accidents.

Solving the problem:

After configuring the smart and safe electricity system, a unified management platform for smart and safe electricity is realized; an emergency, fire protection, and safety supervision linkage mechanism is realized; electrical safety data and fault alarm record traceability are managed; full coverage of the electrical fire system is achieved; a long-term electrical fire early warning mechanism is achieved; an electricity safety assessment and supervision system is implemented to provide data support for the investigation and rectification of electrical safety hazards; electrical fire accidents and electric shock casualties are prevented from occurring.
