What preparations need to be made before street lamp maintenance

2021-01-27

1.1 Check the electrical circuit diagram of the station yard before the street lamp maintenance, and find the street lamp circuit to be overhauled. 1.2 Street lamps Station street lamps can be roughly divided into two types according to their height. One is the 8m street lamp that needs to be lifted by the vehicle to lift the platform, and the other is the 3.5m street lamp. The bamboo ladder used for climbing should be prepared during maintenance. 1.3 The specific operation steps for the overhaul of the 8m high street lamp are as follows: 1.3.1 First listen to the description of the operating personnel about the street lamp is not on, and generally make a preliminary judgment on the street lamp is not on; 1.3.2 Go to the power distribution room and find the street lamp control switch, Close the street light switch to check which street lights are bad. Turn off the street light switch and turn on the street lights of each phase in turn to determine which line the faulty street light is on; 1.3.3 After finding the faulty line and the faulty street light, come to the job site; 1.3.4 Underground operation: After entering the job site, The person in charge of the scene must get off the vehicle to observe the situation on the scene, and then instruct the operating members to divide their jobs, and at the same time place warning signs, delineate the scope of work, and guard the operation of the guardian; 1.3.5 When the lower outriggers of the aerial work truck support the body, the site is responsible One must check the support of the outriggers. The support should be stable, firm, and free of sag. Check that the platform footboard is intact and undamaged; 1.3.6 The maintenance personnel should first check whether the light bulb is illuminated and whether the light is normal before repairing. The dazzling white light may cause the voltage to be too high; the dim light may cause the voltage to be too low. At this time, use a multimeter to measure whether the voltage of the junction box cable is normal; 1.3.7 For the street lamp with the rectifier at the bottom, first open the street lamp junction box to see if the trigger is cracked, see if the rectifier has insulating medium overflow, and see if the capacitor is cracked or burnt. If the above situation occurs, the power supply should be disconnected, and the prepared trigger, rectifier or capacitor should be replaced; 1.3.8 If the bulb of the street lamp does not light up, check whether the cable down-conductor, insurance, and neutral connector are well wired and whether there is Traces of electric discharge and burnt. Gently shake the wiring at all the connections below to see if there is any discharge; 1.3.9 Use a test pencil to test if both ends of the fuse are live, and it is normal. If there is no electricity, measure the cable voltage; change the fuse. If the fuse is burned at this time, it means there is a short circuit in the front part of the rectifier, and you can switch on the light wire; 1.3.10 Disconnect the neutral wire connector and measure whether the neutral wire is live. The power is normal, and the wiring is restored. No electricity or low voltage due to induction, indicating an open circuit in the middle, switch on the light wire; 1.3.11 The rectifier is 8 meters high on the street lamp, and the lamp holder needs to be climbed; 1.3.12 High-altitude part: the driver of the climber operates the folding arm of the aerial work vehicle Before, the person in charge of on-site work must check or inquire about the condition of the driver`s folding arms; check the surrounding overhead lines, structures and other high-altitude conditions; check and urge the climbers to correctly wear helmets, protective clothing, insulating gloves, fasten seat belts, and wear necessary repairs Lamp tools and materials. After the four climbing brackets of the vehicle are erected, perform the climbing operation; 1.3.13 After climbing, the maintenance personnel first observe whether the glass bulb mirror surface of the bulb is white, whether there is black precipitation, and whether the thread at the bottom of the bulb is cracked, look inside the lamp cap Whether the spring is in poor contact due to loss of elastic surface, and whether there is a discharge phenomenon, see whether the trigger is cracked. Check whether the rectifier has an overflow of insulating medium and whether it does not match the power of the bulb used. Check whether the capacitor is cracked or burnt 1.1 Check the electrical circuit diagram of the station yard before maintenance, and find the street light circuit to be repaired. 1.2 Station street lights are roughly divided into two types according to their heights.

The bamboo ladder used for climbing should be prepared during maintenance. 1.3 The specific operation steps for the overhaul of the 8m high street lamp are as follows: 1.3.1 The street lamp first listen to the description of the street lamp is not on by the operator, and generally make a preliminary judgment on the street lamp is not on; .3.2 Go to the power distribution room and find the street lamp control switch, Turn on the street light switch to see which street lights are bad. Turn off the street light switch and turn on the street lights of each phase in turn to determine which line the faulty street light is on; 1.3.3 After finding the faulty line and the faulty street light, come to the job site; 1.3.4 Underground operation: After entering the job site, The person in charge of the scene must get off the vehicle to observe the situation on the scene, and then instruct the operating members to divide their jobs, and at the same time place warning signs, delineate the scope of work, and guard the operation of the guardian; 1.3.5 When the lower outriggers of the aerial work truck support the body, the site is responsible One must check the support of the outriggers.

The power is normal, and the wiring is restored. If there is no electricity or the induction shows low voltage, it means that the middle is open, and the lamp wire should be switched on; 1.3.11 The rectifier is 8 meters high in the street lamp, and the lamp holder needs to be ascended; 1.3.12 The high-altitude part of the street lamp: the driver of the climber operates the aerial work vehicle to fold In front of the arm, the person in charge of on-site work must check or inquire the driver`s folding arm status; check the surrounding overhead lines, structures and other high-altitude conditions; check and urge the climbers to correctly wear helmets, labor insurance clothes, insulated gloves, fasten seat belts, and wear necessary Repair tools and materials. After the four ascending brackets of the vehicle are erected, perform the ascending operation; 1.3.13 After ascending, the maintenance personnel should first observe whether the bulb glass mirror is white, whether there are black deposits, and whether the thread at the bottom of the bulb is cracked. Whether the inner spring is in poor contact due to the loss of elastic surface, and whether there is a discharge phenomenon, see whether the trigger is cracked. Check whether the rectifier has an overflow of insulating medium and whether it does not match the power of the bulb used. See if the capacitor is cracked or burnt.
