First, the basic situation
Xin'an River is a mountainous and tourist city with mountains and rivers. It was built due to the completion of Xin'anjiang Hydropower Station. The terrain of the city is high in the north and low in the south. It has a strip-shaped distribution. There are many slopes in the old city. There are many mountain roads and many old streets. The street lamps are old and aging. With the acceleration of the urbanization process, the newly-built urban roads are wide, the street lights are bright, and the wires and cables in the sky are not seen in the air, and the city taste is also improved. The urban area of ​​the old city is very different. Most of the street lamps are cement pole-type street lamps installed in the 1970s and 1980s. The rectangular plexiglass lamp holders are commonly used. The built-in 150W high-pressure sodium lamps and street lamps for electrical appliances are installed. Although it will still be bright, it is already dilapidated, the light is low, and the maintenance rate is extremely high. In addition, the road is small, the concrete rails and various wires and cables are placed on the sidewalks on both sides of the road, and the old road lamps on the road are covered with rust, rusty old lamps, water accumulated in the lampshade, ballasts, etc. It is not safe for electrical appliances to hang on cement poles. The light at night is low and dark, which damages the image of the city and causes great inconvenience to vehicles and pedestrians. If you run into a peak of electricity, because the voltage is too low, some of the street lights will not start, like a star in the blink of an eye, and some will not light up until the middle of the night. The faults are frequently seen. The public has great opinions and complaints are also very much. The street lamp management department also tried its best to move the brain, such as washing the lampshade and replacing the light bulb, but the effect is not obvious, it is really expensive and laborious.
Second, analyze the reasons and find a way
So is there a way to save money and save money and quickly achieve good results? I have been engaged in street lamp maintenance management for many years, and summarized the status quo and existing problems of the old street lamps in the old city. The main problem lies in the lamp head. Part of the lampshade is yellow and opaque, and there is no reflector behind the bulb. The ballast and trigger are installed in the open air. It is easily aging due to the wind and sun, causing power loss, large power loss, and no compensation capacitor. The starting current is large, the temperature is high, the impact on the bulb and the electric appliance is strong, and the power factor is low (only about 0.4). Another reason is the bare aluminum stranded wire used in the power line, and the lead wire is made of copper core wire (戓 sheathed wire). There are two different metal materials at the wiring, which are caused by different hardness and strength. The oxidation of the aluminum wire often causes poor contact at the joint, and the street lamp also appears black when it is bright. In fact, the bottom line is the problem of the lamp head and the line. As long as it is replaced with waterproof, insect-proof and sealed, the electric appliance can be installed and the heat-dissipating lamp cap assembly (with compensation capacitor, the lamp cover is glass), and the copper-aluminum nose is installed on the copper-aluminum joint of the power line, that is, the lamp cap portion Focus on improvement, a slight improvement on the line part.
Third, there are ways to test
With the method, it is necessary to pay for the action. First, the pilot and the two old roads were retrofitted with lamps and lines. After the transformation, the 150w high-pressure sodium lamp with the same power has doubled the illuminance, and passed the trial for several months. And electricity costs, the failure rate is extremely low, and the electricity bill is also 20% less than the original. I will report on the improved situation and implementation plan to the street lighting management department at the next level, and strive to start in the city.
Fourth, recognition improvement, report approval
This transformation plan was quickly taken seriously by the higher-level leadership departments. Relevant leaders visited the site to check and compare, and approved the practice of retrofitting the street lamps in the old city. They believe that this streetlight reconstruction method is simple in operation, low in cost, and effective in effect. The promotion will be an important project for the upgrading of the municipal facilities in the old town of Xin'anjiang in 2009, and it is required to immediately conduct a comprehensive survey and statistics on the old street lamps in the old city of the city, and prepare the implementation plan and budget for the old street lamp improvement project, and report it to the city. Government approval.
V. The project was approved and carefully implemented
In October 2009, the implementation plan and budget of the old street lamp renovation project in Xin'anjiang District were approved. Through the reasonable arrangement of the construction unit, the construction unit carefully constructed, the supervision unit carefully checked, and I acted as the construction unit. Engineers entering the construction site will carefully and carefully check and test each step of the replacement of the lamp head, the installation of electrical appliances, and the winding of the wire joints. After a month of intense construction, the 483 old streetlights on 67 roads in the old town were improved (replaced waterproof, insect-proof, flood-lighted lamp head assembly, ballasts, triggers, capacitors, fuse boxes) Installed in the lamp cap assembly), the 1800-meter aluminum stranded wire with poor conductivity and poor electrical conductivity is replaced with a copper-core cable, and copper is installed at the junction of the copper lead wire of the 320-inch street lamp and the aluminum twisted main power cable. The aluminum nose, the rusting and brushing of the rusted poles, and the reinforcement of the screws, changed the old and aging old street.
summary
Through the improvement of the old street lamps in the old city, the problems that have been plagued by the government and the citizens for many years have been solved. It has not only changed the image of the roads in the old city, but also improved the city's taste, and more importantly, improved the environment for nighttime traffic. Increased the sense of security at night, the government has done a good thing for the people, and the citizens have really benefited. The other side also saves a lot of money, saving electricity and maintenance costs. This improved method is also worth promoting in other places.
Using a high thermal conductivity aluminum substrate as a circuit board,Pure light color, good heat dissipation, low heat generation and good heat dissipation.
Low light decay, can save you more than 90% of electricity costs.Long life, maintenance-free.
The surface installation is simple and convenient, and the illumination angle can be adjusted according to the installation environment.
High grade, aluminum alloy shell, anodized surface, beautiful appearance, high grade, specially designed for jewelry and other showcase lighting.
