4.3.5. 1 The insulation resistance of the conductive part of each group of lamps to the ground is greater than 10 (2) mω.

4.3.5.2 vertical street lamps, floor-standing street lamps, special courtyard lamps and other lamps are fixed and reliable with the foundation, and all the anchor bolts are capped. The waterproof gaskets of junction box, fuse box and lamp box cover are complete.

The automatic on-off power supply control device of 4.3.5.3 lamps works accurately, and the fuses in the fuse box of each set of lamps are complete and the specifications are suitable for lamps.

4.3.5.4 metal columns and lamps can be reliably grounded (PE) or grounded (PEN) close to bare conductors. The grounding wire is a single trunk line, which forms a ring network along the layout position of the courtyard lamp and is connected with the lead-out wire of the grounding device at least twice. The branch lines led from the main line are connected with the grounding terminals of metal lamp poles and lamps, and marked.

The street lamps on overhead poles in 4.3.5.5 are fixed reliably, the fasteners are complete and fastened, and the lamp position is correct; Each group of lamps is equipped with fuse protection.

4.4 Power-on debugging:

Lamps and lanterns, distribution box (panel) are installed, and the insulation resistance of each branch is qualified before power-on trial operation is allowed. Check the patrol carefully after electrifying, and check whether the lamp control is flexible and accurate; Switches correspond to the control sequence of lamps. If you find any problems, you must turn off the power first, and then find the cause for maintenance.

5 quality control

5. 1 The deviation of the center line of lamps in rows is beyond the allowable range: when determining the position of lamps in rows, the crosshairs must be pulled.

5.2 The grounding (PE) or zero connection (PEN) of metal frames and lamps that can be close to bare conductors and metal hoses is reliable and marked.

5.3 The frame of lamps and lanterns should be fixed reliably, the anchor bolts should be fastened and the lamp holders should be complete; The bolts of lamps and lanterns are fastened without omission. Exposed wires or cables of lamps shall be protected by flexible metal conduits.

5.4 Connect the flexible cord buckle of lamps and lanterns with tin-lined pressing wire. When the screw cap is used, the phase wire is connected to the terminal in the middle of the screw cap.

5.5 The glass cover of large lamps installed in important places should prevent the glass cover from splashing after being broken.

5.6 The pedestal and bracket of floodlight shall be fixed firmly, and the pivot shall be screwed and fixed along the required optical axis.

5.7 The applicable places and installation methods of various lamps shall be installed with reference to the installation schematic diagram and instructions provided by the manufacturer.
