Daily maintenance and maintenance regulations of pole lights:
High-pole lighting refers to high-pole lighting facilities with a pole height equal to or greater than 20m, which are used as large-area lighting facilities such as urban roads and highways, squares, stadiums, airports, port terminals, etc.
High pole lights are divided into three types: fixed type (single column or multi-column), lift type (electric lift or manual lift), and hydraulic tilting type. At present, the more commonly used high-pole lights are electric lift-type high-pole lights - composed of light panels, light poles and foundations, lifting consoles, power distribution systems and lightning protection devices.
High-pole lighting is a special kind of lighting equipment in urban lighting facilities, so its safety and normal use requirements are particularly high. T3076-1998), this is the standard that all enterprises and users who manufacture and use high pole lights need to implement seriously. In particular, the maintenance of high pole lights should not be careless, and the products must be regularly maintained in accordance with the relevant provisions of the product instruction manual.
The main contents of daily maintenance of high pole lights include:
1. Check the hot-dip galvanized anti-corrosion condition of all ferrous metal components (including the inner wall of the lamp pole) of the high-pole lighting facilities, and whether the anti-loosening measures of the fasteners meet the requirements (the anti-corrosion quality should meet the requirements of GB/T9790, GBJ36011 and GB/T11373). related terms).
2. Check the verticality of the high pole lighting facilities (the theodolite must be used to measure and test regularly as required), and the allowable error of the pole should be less than 3‰ of the pole height. The straightness error of the pole axis shall not be greater than 2‰ of the pole length.
3. Check whether the outer surface of the lamp pole and the welding seam are corroded. For those who have experienced a long service period but cannot be replaced, if necessary, use ultrasonic inspection, magnetic particle inspection and other inspection methods to inspect and test the welding seam.
4. Check the mechanical strength of the lamp panel to ensure the safe use of the lamp panel, and check its heat dissipation for the closed lamp panel;
5. Check the fastening bolts of the lamp bracket and reasonably adjust the projection direction of the lamp;
6. Carefully check the use of the wires (flex cables or cords) in the lamp panel to see if the wires are subjected to excessive mechanical stress, aging, cracks, exposed wires, etc. If there is any unsafe phenomenon, it should be dealt with immediately;
7. Replace and repair damaged light source electrical components and other components
8. Focus on checking the lifting transmission system:
(1) Comprehensively check the manual and electric functions of the lifting transmission system, and require the mechanism to be flexible, stable, safe and reliable.
(2) The deceleration mechanism should be flexible and light, and the self-locking function is safe and reliable. The speed change ratio is reasonable, and the speed of the lamp panel should not exceed 6m/min when it is electrically raised and lowered (it can be measured with a stopwatch).
(3) Check the stainless steel wire rope for broken strands, if found, replace it firmly.
(4) Check the brake motor, the speed should meet the relevant design requirements and safety performance requirements;
(5) Check the overload safety clutch and other overload safety protection devices of the transmission system.
(6) Check the electrical and mechanical limit devices, limit devices and over-travel limit protection devices for the lifting and lowering of the lamp panel.
(7) When a single main wire rope is used, the reliability and safety of the braking or protective device to prevent accidental fall of the lamp panel should be checked. After the lamp panel of the wire rope is raised in place, check the automatic hooking and decoupling unloading device to ensure that the hooking and decoupling are free.
(8) Check the lines in the rod, which must be firmly fixed without being compressed, clamped or damaged.
9. Check power distribution and control equipment
(1) The distribution line and the lamp panel line should be fixedly connected.
(2) The wire connection should be firm and reliable, without loosening and falling off.
(3) Check the three-phase load balance and the control of the midnight light.
(4) Check the electrical connections. When there may be torsion, bending and vibration, they should be securely and reliably fixed without loosening.
10. Electrical safety performance inspection, check the insulation resistance between the power supply line and the ground: not less than 10M health?
11. Inspection of protective grounding and lightning protection devices
(1) Metal lamp poles and metal casings of electrical equipment should have good protective grounding (2) Check the lightning rod fixation;
12. Measure the plane of the foundation panel with a level ruler, and analyze the uneven settlement of the foundation based on the inspection results of the verticality of the light pole, and make corresponding treatments.
