Adopt new LED street lamps
LED street lamps and refers to semiconductor lighting lamps, which are composed of yellow phosphors and GaN-based power blue LEDs, and are high-efficiency white light diodes powered by low-voltage DC. Because they are solid-state cold light sources, they have the advantages of less power consumption, no pollution, and environmental protection. . In recent years, although LED street lights have developed rapidly, there are still some shortcomings. It is easy to cause problems such as flare and so on. However, as a new light source, LED will be widely used with the advancement of technology.
Install a power saver
We all know that, affected by the load, the grid voltage is too high when the load is low, and the voltage is too low when the load is peak. The grid load is at a low point near midnight, and the grid voltage is low in the evening, but the grid voltage is too high. This kind of unreasonable phenomenon leads to the phenomenon of serious waste of funds and energy. The square of the voltage and the consumption of electric energy are proportional to the same load. After the electrical appliance is installed at the power supply point, the lighting voltage can be stabilized or reduced to around 220V, which can effectively prolong the service life of the bulb and reduce the active electricity bill.
Integrate existing transformers
Because when designing road lighting, the transformers all have partial loads, so in the process of use, there may be changes in the power supply lines, resulting in low efficiency and low load rate of some transformers. In the electricity bill, the reactive power loss of the transformer no-load accounts for a large proportion, which is obviously wasteful. Therefore, the load can be incorporated into the adjacent transformer to achieve the purpose of energy saving, reduce the reactive power loss, and improve the utilization rate of the transformer. According to the calculation of kVA/24 yuan, after a 250kVA transformer is deactivated, 72,000 yuan can be saved a year, which is a considerable amount.
Explore new energy street lights
New energy street lamps refer to the conversion of wind energy, solar energy and other energy sources into electrical energy for street lighting use. The most typical ones are wind-solar hybrid street lamps and solar street lamps. Wind-solar complementary street lights can make up for the shortcomings of independent application of photovoltaic and wind power, and can convert light energy and wind energy storage into electrical energy at the same time. However, due to the inconvenient maintenance of new energy street lamps, limited battery life, and high one-time investment and other unfavorable factors, they have not yet been widely used. Solar street lights refer to the collection of light energy through solar energy storage panels, and the conversion of solar energy into electrical energy at night, but the battery technology of solar street lights is not yet very mature, with high investment and short life.
