Theory of the old city of old road reconstruction project solar lamp case

a, basic condition of the xin an river is a mountain scenic tourist city, built by the completion of the xin an river hydropower station, city terrain north south high low, strip type distribution, and the old city green hill, col road is much, much old street old alley, street lamp aging. With the speeding up of urbanization process, the new urban road spacious, street light and bright, the air also see executions, wire and cable, also raised the city grade. And old cities are very different, most street lamp is installed in the eighty s, concrete pole mounted lamp, rectangular organic glass lamp holder is widely accepted, the built-in 150 w high pressure sodium lamp, electric appliances of street lamp, although now also bright, but that is worn out, low light and dark, repair rate is extremely high. Coupled with the narrow road, the road on both sides of the sidewalk with concrete pole and all kinds of wire and cable, over the road driving the rags, rusty old street lamp, lamp shade inner product water, ballasts and other appliance on the concrete pole, nor safe, low dark night light, harm the image of the city, to vehicles and pedestrians caused great inconvenience. If meet with peak demand, because of the low voltage part of street lamp can't start, like the stars in the blink of an eye, some to light up until after midnight, the fault is frequent, public opinion is very big, the complaints are also much more special, street lamp management department also try, the way to move enough brains, such as 淸 washing chimney, replacing light bulbs, but the effect is not obvious, is costly and time-consuming.

2, analysis the reason, find out the way to the

so is there a convenient save save money, the idea that will soon be able to achieve good results? I have been dealing with street lights maintenance management for many years, to the situation of old street of old city and the analysis of existing problems are summarized, the main problem is that the chimney of lamp holder parts yellow not pervious to light, the light bulb behind no reflector, ballast, trigger installed in the open air, the wind or sunshine, it is easy to aging, cause the loss of power, the power loss, not compensation capacitor, causing large starting current, high temperature, the impact of the strong of light bulbs, electrical appliances, power factor is low (only 0. 4). Another reason is that the power supply circuit adopts the bare aluminum wire, and wire is copper wire (戓 sheathed wire), the connection is that two different kinds of metal materials, because of different hardness and strength, resulting in the oxidation of aluminium wire, often in tapping sparks will cause poor contact, street light will appear bright black phenomenon. In fact in the final analysis is the lamp holder issue, the line problem. Into insect good sealing, waterproof, should be replaced with good sex of electric equipment can be installed, and heat lamp holder assembly (a compensation capacitor, chimney is glass), the power circuit of copper aluminum joint installation copper nose, namely the lamp holder part focus on improvement, some methods to make a little improvement on lines.

3, a way,

have a way to test results show that grants the action, to pilot lamps and lanterns of two remote path and line, after modification, the same power of 150 w high pressure sodium lamp light than the original increased one times, through several months of trial and electricity measurement, failure rate is extremely low, electricity prices than the original a saving of 20%. After I will improve the situation and the implementation plan of the lamps in the higher management department made the report, in the city.

4, recognition improvement, report the approved

this retrofit scheme quickly got the leadership department seriously, the leading personnel performance examination, the practice of the transformation, accepted the old street lamp that lights transformation method is simple, low cost, obvious effect, worthy of promotion, will be 2009 in xin an river old city municipal facilities improve one of the important projects, and require immediate old street of old city in urban areas to conduct a comprehensive survey statistics, prepare the old street lamp improvement project implementation plan and budget, report to the municipal government for approval.

5, project approval, carefully implement the

in October 2009, xin an river city of old street reconstruction project implementation plan and budget approved, through the reasonable arrangement of construction units, construction units of careful construction, the supervising units carefully to check, as the construction unit to send into the construction site engineers, on the replacement of their a street lamp lamp holder, electrical installation and wire connection around, each procedure, seriously, carefully check and test. After a month of intensive work, 483 of the old road 67, the old street lamp was improved (replacing the waterproof, insect-resistant, floodlight strong sex of lamp holder assembly, ballast, trigger, capacitor, fuse box installed in the lamp holder assembly), the aging of the burns, severe, 1800 meters about the worse performance of conductive aluminum stranded wire change into copper core cable, copper of 320 streetlights lead wire and aluminum ground connection of the total power cord installed copper aluminum nose, light pole of rust cleaning brush paint, reinforcing the screw, changed the old street of the aging face. Nodule

through the improvements on the old old street lamp, solved the problems in the government and citizens the problem for many years, not only changed the image of the old road, improve the urban grade, more important is to improve the traffic environment at night, increased security in the night, is run by the local government has a good thing to the practical work, people really gained. The other side also save a lot of money, save the electricity and maintenance costs. This improved method, also is worth popularizing in other places.
