Construction technology and acceptance standard of garden lights

Garden light construction technology
1 Process Flow
Luminaire inspection → Luminaire installation → power-on trial operation

2 Operation process
1) Garden light installation
The courtyard lighting source uses LED lights. The insulating resistance value of the conductive part of each set of lamps to the ground
The value must be greater than 2 Mω.
Garden lights should be installed vertically, pillar street lights, floor street lights, special garden lights and other lights
The tool should be securely fixed to the foundation, and the anchor bolt cap should be complete. Fuse box in each set of lamp
Complete silk, specifications and lamps fit. The junction box or fuse box of the luminaire, the lid of the box is waterproof and tight
The sealing pad shall be installed completely.

 

 

2) Grounding of garden lights
Strict attention should be paid to the grounding of garden lights. Metal posts and lamps can be approached with bare conductors
PEN cable connection is reliable. The ground line should be a single trunk line, and the trunk line should be arranged along the garden lights to form a ring network
The grounding trunk should be connected with the grounding device outlet trunk at no less than 2 places. From the ground trunk to
The lead out branch is connected with the ground terminal of the metal lamp post and the lamp, and is marked.
The grounding branch of the lamp can not be connected in series with the lamp to prevent the individual lamp from shifting or changing
Make other lamps lose ground protection.

 

3) Power trial operation
After the installation of the lamp, after passing the insulation test and inspection, it is allowed to power on trial operation.
After the power should be carefully inspected and toured, check whether the control of the lamp is flexible and accurate; Switch and
Whether the lighting control sequence corresponds, if the problem is found, power off immediately, find out the cause and repair.

3 Quality Standards
1 Main control Project

1. The installation of garden lights shall comply with the following provisions:

(1) The insulation resistance of the conductive part of each set of lamps to the ground is greater than 2MΩ.

(2) Pillar street lights, floor street lights, special garden lights and other lamps can be fixed with the foundation

Damn, anchor bolt caps are complete. Junction box or fuse for luminaire, waterproof gasket for box lid

Complete.

(3) Metal posts and lamps can be close to the bare conductor ground (PE) or zero (PEN)
The grounding line is provided with a single main line, and the main line is arranged into a ring network along the courtyard light, and there are not less than 2 and
Grounding device lead wire connection. The main line leads the branch line to the ground terminal of the metal lamp post and the lamp
Connected and identified.

 

 

2 General Items

1. The installation of garden lights shall comply with the following provisions:
(1) The fuse in the fuse box of each set of lamps is complete, and the specifications are suitable for the lamps.

 

4 Finished product protection

1. Storage should be strengthened during installation and transportation, and batches of lamps should be placed in the finished product warehouse
Neat and firm. Handling should be handled gently, so as not to damage the surface of the galvanized layer, paint and glass
A glass hood. Set up a special person to keep it, establish a responsibility system, and disclose the finished product protection technology to the operators.
You should not remove the wrapping paper too early.
2. Do not damage the doors, Windows and walls of the building when installing the lamps.
3. The lamp shall not be sprayed again after installation to prevent contamination of the appliance.
4. After the completion of the construction of the electrical lighting device, the buildings and structures caused by the construction
Partial damaged parts should be repaired completely.

5 Quality problems that should be paid attention to

The wiring and grounding of the yard lights and lawn lights of buildings are not reliable

(1) Phenomena

The metal shell of the garden light and lawn light has no special ground terminal; The ground cable is free and installed

Fixing screws are crimped on the same seat; Large garden lighting grounding without grounding trunk; luminaire

The junction box is not waterproof.

(2) Prevention and control measures

1) The metal shell of the garden lamp and lawn lamp requires a special ground terminal;
2) Specially designed grounding trunk, grounding trunk along the lighting arrangement to form a ring network, and many
At 2 places connected with the grounding device of the main line, the metal lamp post and each set of lamps special connection
The ground terminal is connected with the ground main line with a branch line, and the anti-loose washer at the connection is complete and tightly tightened.
And pay attention to waterproof, rust prevention, grounding mark;
3) Waterproof lamps and use waterproof junction boxes should be selected;
4) In the large garden should pay attention to laying repeated grounding poles, each set of lighting fuse (fuse)
Should be adapted to lamps.

6 Environmental, occupational health and safety management measures

1 Environmental management measures

1. Assemble the lamps and install the wires and insulation layers left over from the lamps and lamps shall not be disorderly anywhere
Discard, should be sorted and stored in the designated place.

2. The packaging tape of the lamp, the wrapping paper of the lamp and the lamp tube shall not be discarded anywhere, and should be classified collection and storage in designated place.

3. The building ash that falls during the installation of lamps should be cleaned up in time.
4. Burnt out light bulbs and lamp tubes shall not be discarded anywhere, and shall be collected and handed over to the designated responsibility
People unified processing.

2 Occupational health and safety management measures

1. The appropriate ladder should be selected according to the installation height of the lamp, and the top of the ladder should be connected firmly
Solid, from the bottom of the ladder 40cm ~ 60cm to set the strength of enough rope, do not stand on the top layer of the ladder work. Do not throw tools or tool belts from the high ladder.

2. The shell, handle, load line, plug, switch, etc. of handheld power tools must be finished. Good non-destructive, before use to do no-load test check, normal operation before use.

 

3. Before using handheld power tools, short circuit the isolation switch and switch box of power tools
Carefully inspect the protection, overload protection and leakage protector, and after the switch box is checked,
To use hand-held power tools.

4. In the construction of open air or humid environment, priority is given to Class II hands with isolation transformers
Holding power tools, if the use of class II handheld power tools, must be equipped with anti-splash leakage protection
Guard, the isolation transformer or leakage protector installed outside the narrow place, and set up special care.

5. The load line of hand-held power tools adopts climate-resistant rubber sheathed copper core flexible cable.
There must be no joint.
