Abstract In this paper, the working instructions for standardized lamp repair are written for common faults of sodium lamps and possible danger points. Key words street lamp monitoring lighting energy saving In order to standardize the practice of conventional lamp repairing operation and improve work efficiency, Xiaogan Street Light Management Bureau combined with the actual situation, after analyzing the common faults of sodium lamps and possible dangerous points, prepared the operation instructions for standardized lamp repair. . The following is the analysis process and specific procedures of the conventional light repair operation, I hope that the peers will be axe. 1. Analysis of common fault conditions of high pressure sodium lamps 1. Burning of fuses. Cause: The fuse is of poor quality or has an end of life; there is a short circuit on the lead wire. 2. The bulb burned out. Cause: The lamp quality is poor or the life is due; the rectifier is not matched; the system voltage is too high; the rectifier is short-circuited between turns. 3. The trigger is faulty. Cause: The trigger is of poor quality or has reached the end of its life; after the lamp has burned out, the trigger is constantly triggered to damage the trigger. 4, the lamp head is faulty. Cause: The quality of the lamp head is poor or has reached the end of life. The spring loses its elasticity, and the contact is poor, causing an open circuit. The high-voltage pulse of the trigger causes the lamp cap to arc, causing the lamp cap to short-circuit. 5. The rectifier is faulty. Cause: The open circuit of the rectifier terminal is open due to poor contact or burnout; the rectifier is short-circuited by a short turn to burn the lamp; the insulation damage of the rectifier causes the case to be charged. 6. Inverted line fault (refers to the fault between the power supply and the rectifier). Cause: The external force is broken or the joint is blown to open the lead line; if the external force is broken or the current is too large, the line is short-circuited. 7. Lamp line failure (refers to the connection failure between the rectifier and the lamp head). Cause: The external force is broken or the joint is blown to open the lamp; the external force is broken or the trigger of the high-voltage pulse of the trigger causes the weakening of the insulation of the lamp wire to be short-circuited; the external force is broken or the trigger is caused by the high-voltage pulse of the trigger. Connect the lamp housing to cause the lamp housing to be charged. 8. Poor contact (time-breaking phenomenon). Cause: The direct contact area of ​​the copper-aluminum wire is poorly contacted due to long-term oxidation. 9, capacitor failure. Capacitor faults are generally rare, mainly open and short. Cause: The open circuit caused by the explosion of the capacitor due to quality or high voltage does not affect the lighting; the short circuit caused by the burning of the capacitor due to quality or high voltage, and the fuse is burned at this time. 10. Power failure. Cause: There is no power supply voltage or voltage shortage due to cable failure; the power supply radius is too large and the terminal voltage is insufficient; the system voltage is too low or too high. Second, the possible dangerous point analysis 1, the driver drunk driving, a traffic accident. 2. During nighttime maintenance, there is no warning sign after parking, causing rear-end collision of vehicles. 3. After the aerial work vehicle arrives at the maintenance site, the landing point is unstable, and the car body tilts during the work. 4. During the operation of the aerial work vehicle, accidentally touch the surrounding high and low voltage overhead lines or structures. 5. During the operation of the aerial work vehicle, the height of the rotating arm is not enough, causing the past super high-vehicle to collide with it. 6. During the operation of the aerial work vehicle, the work bucket is tilted due to the failure of the arm, causing the maintenance personnel to fall at a high altitude. 7. In the case of high-altitude maintenance, the following personnel are injured due to the upper and lower parabola or the falling object. 8. The electric shock caused by the maintenance personnel during the electrified maintenance. Maintenance of sodium lamp specification procedures I. Requirements and instructions: 1. Maintenance personnel are required to recognize relevant electrical materials and to complete the wiring independently and correctly. 2. Maintenance personnel should be familiar with the common fault point analysis and dangerous point analysis when repairing sodium lamps, and deeply understand the maintenance procedures. 3. When the maintenance personnel enters the work site, they must do “two wear and one wearâ€, and the climber must fasten the belt. 4, maintenance personnel must prepare the necessary tools and materials: test pencil, multimeter, trial trigger, trial bulb, sheath wire, etc., and ensure its reliability.
