Recently, relevant national departments jointly issued the "Action Plan for Green and Low - Carbon Development of the Information and Communication Industry (2022 - 2025)" (hereinafter referred to as the "Plan") to promote the green, low - carbon and high - quality development of the information and communication industry during the "14th Five - Year Plan" period and empower the whole society to save energy, reduce emissions and promote the peak of carbon emissions. As a new generation of urban information infrastructure, smart light poles have been widely applied in projects. With the development of society and the improvement of people's living standards, the lighting electricity consumption in China has accounted for 7% - 8% of the total electricity consumption. According to the "China Green Lighting Project" put forward by China, lighting electricity consumption has become an important aspect of energy conservation. Power saving means promoting energy - saving lighting appliances, improving the utilization rate of electric energy and reducing electricity consumption on the premise of ensuring illuminance. As night falls, people's electricity consumption increases, and the voltage fluctuates greatly, which not only wastes electric energy but also may cause damage to street lights. It is necessary to configure a special voltage stabilizer for lighting. The rated working current (A) of the smart street light lighting voltage - stabilizing and power - saving device: 20A, 30A, 40A, 45A, 50A, 60A, 63A, 80A, 100A, 120A, 125A, 150A, 160A, 170A, 180A, 190A, 200A, 250A, 300A, 315A, 400A;
Smart street light lighting voltage - stabilizing and power - saving device KTJSQ - 3/80A remote light control system. Reasons for short - circuit faults of street light controllers
The insufficient short - circuit resistance of the controller itself is the main reason for the short - circuit damage of the controller.
In addition, improper operation and management is also a non - negligible factor.
The insufficient short - circuit resistance of the controller is mainly manifested in that some controllers still experience winding deformation and even insulation breakdown after being impacted by a short - circuit current lower than the specified intensity and with fast - acting protection.
For example, in a controller at Binhe Station in Kaifeng, Henan, due to a three - phase short - circuit of the bus cable of the low - voltage side line, the main transformer heavy protection action tripped, resulting in a disconnection of phase A on the low - voltage side of the controller and a displacement of the iron core.
However, the short - circuit current was only 4.5 times the rated current, and the protection action time was 0.08s.
Technical indicators of the smart street light lighting voltage - stabilizing and power - saving device:

The lighting voltage stabilization and power-saving device adopts a manual and automatic dual-bypass system to ensure that the lighting equipment is continuously powered and operates normally and safely; the control part of the regulation device does not contain AC contactors, no contacts and moving components, ensuring high reliability and low power consumption. An optional GSM/GPRS real-time (mobile phone) monitoring system can be used to monitor the operation of the equipment through signals such as display and sound, alarm for faults, and take protective measures in time.
Instruction Manual for KTJSQ-3/80A Remote Light Control System of Intelligent Street Lighting Voltage Stabilization and Power-Saving Device Street Light Controller Precautions
1. The control of the input power supply and bypass of this equipment must be controlled by the control signal of this equipment. Otherwise, when the equipment detects overcurrent, overvoltage, and equipment faults, it cannot automatically cut off the input power supply and automatically bypass, which may cause damage to the equipment.
2. Do not touch any live parts after the product is powered on.
3. Be sure to cut off the power supply before implementing connections or related operations; otherwise, it may cause electric shock or product damage.
4. Be sure to set a circuit breaker at the input end of this product to ensure safety.
5. When installing the energy-saving controller le=300A, please ensure that the box is well grounded; do not disassemble and modify the product without permission, otherwise it may cause faults, electric leakage, and even fire.
6. Do not reverse the input/output, and do not reverse the phase line and neutral line;
7. Do not place any items on the top of this product;
What are the advantages of the street light energy-saving device?
It has an intelligent meter that can clearly display data such as voltage and current, with a very high resolution. The operation accuracy of the membrane buttons is also very high, with a very low error rate and high safety.
Second, its response speed is very fast. Even if the input voltage fluctuates greatly, the output voltage can always remain at the regulated voltage value set by the user, because its voltage regulation speed is 20 milliseconds.
In addition, it will not have any impact on the voltage changes of any production equipment and instruments, nor will it cause phenomena such as over - voltage and under - voltage bypass tripping of any equipment. Therefore, it does not have the function of automatically returning to the voltage regulation state after the voltage returns to normal.
Third, during the startup process, it does not have the compensation function of general power voltage regulation and stabilization devices. Instead, it makes corresponding compensation after detecting the output voltage value after startup. This ensures the stable operation of the equipment and also protects the performance of the equipment. On the other hand, it also correspondingly extends the service life of the equipment. This is a blessing for a wide range of equipment. Customers don't have to worry about the problems of frequent maintenance and replacement of the equipment. Moreover, this design also ensures that the equipment will not burn out the electrical equipment due to the phenomenon of too high or too low output voltage during startup on the other hand.
