How to estimate the load of street lights in the common part of the stairway

There are many ways to estimate the load of street lights in the common part of the stairway, but I will introduce a common method below.

First of all, we need to understand the power and usage time of street lights in the common part of the corridor. Generally speaking, the power of street lights in the common part of the corridor is between 10 watts and 50 watts, and the use time is generally from 6 p.m. to 6 a.m. the next day, that is, 12 hours.

Secondly, we need to calculate the total power of the street lights in the common part of the stairway. Assuming that the power of the street lights in the common part of the corridor is 30 watts, then the total power can be calculated by the following formula:

Total Power = Power of a Single Street Light Number of Street Lights.

Assuming that there are 10 street lights in the common part of the stairway, then the total power is:

Total power = 30 watts 10 = 300 watts.

Next, we need to calculate the total power consumption of the street lights in the common part of the stairway. Electrical energy consumption can be calculated by the following formula:

Total power consumption = total power usage time.

Assuming that the use time of the street lights in the common part of the corridor is 12 hours, then the total electrical energy consumption is:

Total power consumption = 300 watts 12 hours = 3600 watt hours.

Finally, we can convert the total electrical energy consumption into electricity bills. The electricity bill can be calculated by the following formula:

Electricity cost = total electricity consumption and electricity price.

Assuming that the electricity price is 1 yuan kWh, then the electricity bill is:

Electricity = 3600 watt-hours 1 yuan kWh = yuan.

Through the above methods, we can estimate the load and electricity cost of the street lights in the common part of the corridor. Of course, this is only an estimation method, the actual situation may vary, and other factors need to be considered, such as the actual power of the street lights, changes in the time of use, etc.

Estimated according to the load when all the street lights in the common part of the corridor are turned on.

Foundation works (trenching, downpipe, concrete underlaying. There's the labor cost, the cost of the protective pipe, the amount of concrete cubes. The embedded parts generally come with the lamp.

Poles, threaded cables. Labor costs, cable costs.

Short-distance shipping costs.

Crane fee (more than 6 meters must be used).

Transformer costs.

1. Concrete excavation of street lamp pole foundation;

2. Street lamp pole foundation concrete;

3. Street lamp pole foundation concrete and embedded parts (lamp pole anchor screws);

4. Lamp pole and lamp installation;

5. Timing switch installation;

6. digging trenches for cables;

7. Cable laying;

8. Laying protective pipes;

9. backfilling;

10. a cover plate.

It should be emphasized that the main material cost of lamp pole and lamp installation, timing switch installation, cable laying is added, because the item is only the installation fee, excluding the main material cost, and then the fixed amount can be taken, and the street lamp project is generally so much.

Lamps, light poles, cables, cable protection tubes, light pole foundations, distribution boxes, etc.

Lamps, cables, poles, foundation parts, etc.

Please provide relevant information: pavement width, pavement material, bucket dust indicator street lamp height, street lamp spacing, whether there is power requirement, whether there is a brightness requirement, whether there is a budget requirement, and then I will calculate it for you according to the information provided by your brother, otherwise it will not be calculated. If no scenario is involved, provide the width and height of the pavement.

If you need help with your budget, you can contact me!

The voltage is high in the middle of the night, and it is easy to burn out the electric filament. Two old lamps with filament in the same wattage can be connected in series and then connected to a 220-volt power supply. I've been doing this for more than ten years, and it's not bad.

The kind of old-fashioned electric lights that are connected in series – either with welded wires or with two lamp heads. Pay attention to insulation, safety.

You ask, ask the street lights.

What is the budget for the project?

Answer: 1. Concrete excavation of street lamp pole foundation;

2. Street lamp pole foundation concrete;

3. Street lamp pole foundation concrete and embedded parts (lamp pole anchor screws);

4. Lamp pole and lamp installation;

5. Timing switch installation;

6. digging trenches for cables;

7. Cable laying;

8. Laying protective pipes;

9. backfilling;

10. a cover plate.

It should be emphasized that the main material cost of lamp pole and lamp installation, timing switch installation, and cable laying is added, because

The item is only the installation fee, excluding the main material fee, and then the fixed amount can be taken, and the street lamp project is generally so much.

Street lamps are municipal projects, and municipal quotas are applied.

Generally, the project content to be counted is:

1, chisel concrete pavement, 2, cable trench earthwork, 3, lay cable protection pipe, (if not casing directly buried this item is not changed to sand cover bricks). 5, street lamp foundation steel reinforcement, 4, street lamp concrete foundation pouring, 5, iron paint, 6, cable installation, 8, cable head security, 8, vertical lamp pole, 9, lamp installation, 10, complete set of distribution box installation, (including time controller, time controller does not need another set of quota, the timing switch on the first floor is the time controller). 11. Street lamp number (column as needed, if not numbered, do not count).

11. Earthwork backfill or external transportation, 12. System debugging. 13. Grounding electrode safety, 14. Grounding bus security, 15. Grounding device debugging. 16. pouring concrete pavement.

The above content is all in these municipal quotas, so let's learn it slowly. It's best to ask someone around you who has done a budget.

How much does it cost to install an 8-meter-high street lamp foundation, pay-off, dig trenches, and fill the soil.

Municipal street lamp** has a saying that it is directly buried. Now the installation works are all using the list**.

A dual-control lighting circuit is sufficient.

Note that you want to use a double-throw single-throw switch. You have to buy it specifically, otherwise it is easy to buy the wrong one.

Let this street lamp be x meters high from the ground.

x:(9+1)=:1

x=16 This street light is 16 meters above the ground.
