Today talk about the daily maintenance and maintenance of high pole lights

Daily maintenance and maintenance regulations of pole lights:

High-pole lights refer to high-pole lighting facilities that are equal to or greater than 20m in height and are used as large-area lighting facilities for urban roads and highways, squares, stadiums, airports, ports and docks.

High pole lights are divided into three types: fixed (single column or multi-pillar), lifting (electric lifting or manual lifting), and hydraulic tilting type. At present, the more commonly used high-pole lights are electric lifting high-pole lights-composed of lamp panels, light poles and foundations, lifting consoles, power distribution systems and lightning protection devices.

The high pole lamp is a special kind of lighting equipment in urban lighting facilities. Therefore, its safety and normal use requirements are particularly high. For this reason, the Ministry of Construction issued the "Technical Conditions for High Pole Lighting Facilities" in 1998 (CJ/ T3076-1998), this is a standard that all enterprises and users who manufacture and use high pole lights need to implement carefully. Especially the maintenance of high pole lights should not be careless, and the products must be maintained regularly in accordance with the relevant provisions of the product 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 light 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 The relevant provisions).

2. Check the verticality of the high-pole lighting facilities (theodolite must be used to measure and test regularly according to the requirements and regulations), and the allowable error of the pole should be less than 3‰ of the height of the pole. The straightness error of the axis of the pole shall not be greater than 2‰ of the pole length.

3. Check whether there is corrosion on the outer surface of the light pole and the welding seam. If it has been in service for a long time but cannot be replaced again, the welding seam shall be inspected and tested by ultrasonic, magnetic particle inspection and other inspection methods if necessary.

4. Check the mechanical strength of the lamp panel to ensure the safe use of the lamp panel. For a closed lamp panel, check its heat dissipation;

5. Check the fastening bolts of the lamp bracket, and adjust the projection direction of the lamp reasonably;

6. Carefully check the use of wires (flexible cables or cords) in the lamp panel to see if the wires are subjected to excessive mechanical stress, whether there are aging, cracks, or exposed wires. If unsafe phenomena occur, they should be dealt with immediately;

7. Replace and repair damaged light source appliances and other components

8. Focus on checking the lifting transmission system:

(1) Comprehensively check the manual and electric functions of the lifting transmission system, requiring flexible transmission of the mechanism, stable lifting, safety and reliability.

(2) The speed reduction mechanism should be flexible and light, and the self-locking function should be safe and reliable. The gear ratio is reasonable, and the speed of the lamp panel should not exceed 6m/min when it is raised and lowered electrically (it can be measured with a stopwatch).

(3) Check whether the stainless steel wire rope has 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 of the lamp panel lifting.

(7) When a single main wire rope is used, the reliability and safety of the braking or protective device to prevent the lamp panel from accidentally falling should be checked. After the lamp panel of the wire rope rises into place, check the automatic hanging and unhooking unloading device to ensure that the hanging and unloading are free.

(8) The line inside the inspection pole must be firmly fixed and free from compression, clamping, or damage.

9. Check power distribution and control equipment

(1) The power distribution circuit and the lamp panel circuit should be fixedly connected.

(2) The wire connection should be firm and reliable, without loosening or falling off.

(3) Check the three-phase load balance and the midnight light control.

(4) Check the electrical connections. When torsion, bending and vibration may occur, they should be securely and reliably fixed without looseness.

10. Electrical safety performance inspection, check the insulation resistance between the power supply line and the ground: not less than 10M?

11. Inspection of protective grounding and lightning protection devices

(1) Metal light poles and metal shells of electrical equipment should have good protective grounding (2) Check the fixing of the lightning rod;

12. Measure the plane of the foundation panel with a horizontal ruler, and combine the inspection results of the verticality of the light pole to analyze the uneven settlement of the foundation and make corresponding treatments.
