THLXD-PT-60A, THLXD-PT-30A, THLXD-PT-40A national road street lamp power-saving voltage stabilizers use voltage stabilizers to regulate the voltage of lighting facilities, which is an effective means. Currently, the lighting fixtures on the newly built expressways in Jiangxi Province all adopt the voltage stabilization scheme using voltage stabilizers, which has drawbacks such as over - reliance on the performance of voltage stabilizers, high construction costs, and insufficient self - robustness. The national road street lamp power - saving voltage stabilizer analyzes the voltage stabilization scheme for enhanced lighting according to the characteristics of enhanced lighting in the entrance section, transition section 1 and 2 of lighting. Through the analysis of the characteristics of enhanced lighting in lighting, using its own voltage stabilization function for voltage regulation can ensure the safety of the equipment, and make full use of its own voltage stabilization function during construction. This voltage stabilization scheme saves construction costs and meets the normal and safety requirements of lighting.

Analysis of the energy-saving effect of the national road lamp power-saving voltage stabilizer
According to the data of the trial operation of LED road lamp transformation in a certain city, the actual operating power of LED road lamps is 10% higher than the rated power of the lamps, and the actual operating power of high-pressure sodium lamps is 30% higher than the rated power of the lamps. Before the transformation, there were 10067 high-pressure sodium lamps with a total power of 2525.2kW. After the transformation, there were 9068 LED lamps with a total power of 979.08kW. The actual operating powers are as follows: High-pressure sodium lamps: 2525.2×1.3 = 3282.7kW, LED lamps: 979.08×1.1 = 1077kW. According to the current operating situation of the road lamps in this city, the average daily operating time of the road lamps is 11 hours and they operate 365 days a year. Then the electricity saved after the transformation is: (3282.7 - 1077.0)×11×365 = 8.8567 million kWh. The energy-saving effect after the transformation reaches 67.1%.
2. Economic benefit analysis
Through the implementation of the road lamp energy-saving transformation, the average electricity price is 0.844 yuan/kWh. The operating cost saved by the power-saving part is as follows: Before the transformation, the annual electricity cost to be paid is 3282.7×11×365×0.844/10000 = 11.12 million yuan. After the transformation, the annual electricity cost to be paid is 1077×11×365×0.844/10000 = 3.65 million yuan. The electricity cost saved before and after the transformation is 7.47 million yuan.
3. Emission reduction effect analysis
Carrying out the energy-saving transformation of road lamps can effectively save the electricity consumption of road lighting, thus saving the consumption of coal for power generation. It plays a positive demonstration role in the emissions of pollutants such as CO₂, SO₂, NO, soot, and ash slag. According to the relevant data of NREL (National Renewable Energy Laboratory in the United States), the current CO₂ emission index of thermal power plants is about 0.75kg/kW·h, and the emission indices of SO and NOₓ are about 0.006kg/kW·h and 0.0045kg/kW·h respectively. In addition, according to the data released by the Statistical Information Department of the China Electricity Council, the coal consumption for power supply is 350g/kW·h.
