Led street lamp installation process and construction method

I. Insulation test: Use the vibration meter to measure the insulation resistance between the wires and the ground. Check whether the cable is free or not. The test values should meet the requirements of the specification. After the telemetry is completed, the core wire should be discharged to the ground. The end of the cable is sealed with a rubber bag and wrapped with tape.

Second, street lighting equipment:

1. The height of the street lamp equipment in the same direction (from the light source to the ground), the elevation angle, and the direction of the lamp should be adhered together.

2. The longitudinal centerline of the luminaire and the longitudinal centerline of the lamp arm should be together. The horizontal horizontal line of the luminaire should be parallel to the ground. After tightening, the visual inspection should be free of skew.

3. The lamp holder is fixed and reliable. The adjustable lamp cap should be adjusted to the exact position according to the plan. The lamp head wiring should conform to the rules.

4, a variety of nuts fastening, should be added gaskets and spring pads.

Third, electrical equipment:

1. After the materials are inspected, they can be inspected by unpacking and checked.

2. The center line of the moving contact and the static contact should be together, and the contact should be in close contact.

3. The switching contact of the secondary circuit auxiliary switch should be accurate and reliable.

4. Mechanical locking and electrical locking action should be accurate and reliable.

5. The grounding system needs to be robust and reliable and meet the requirements of drawings and specifications.

IV. Test and pressure test: It is necessary to use the debugging equipment, surface and instrument to be qualified by the relevant units that have been qualified by the state, and be used and kept by special personnel.

1. The insulation test of the electrical circuit is necessary, the impedance matching is appropriate, the wiring is accurate, and the symbol is clear and complete.

2, the surface should be active, accurate measurement, accurate zero, indicating accuracy, variation, accuracy of recording in line with the requirements of the specification.

3. After the equipment is completed, check it and acknowledge that it is correct before proceeding with sub-programming.

4. After the debugging of each sub-item is completed, system debugging, linkage debugging and trial operation can be performed.
