Stop at the red light and go at the green light. This is what we have known since childhood. Any mode of travel needs to rely on traffic lights, that is, the traffic lights we often say
Traffic lights maintain traffic order, so its stable operation is very important. Power failure will not only lead to traffic chaos, but also lead to traffic accidents. Do you know where the power of traffic lights comes from? Who is paying the electricity bill for it?
Where does the traffic light come from?
Most of the traffic lights come from the power grid. The traffic lights powered by electricity meters installed by the power supply company are traffic lights with “identity”, which can find the household number of electricity meters, and the power supply company has a clear understanding of their operation. A small number of traffic lights are mobile solar traffic lights.
However, many traffic lights that meet the regulations are “black households”, and their electricity is “borrowed” from nearby sources: nearby street lights, enterprises, public substation areas, etc.. Usually, the power supply company does not know the operation of these traffic lights~
Who will pay the electricity bill for the traffic lights?
Of course, traffic lights need to pay electricity bills. For those traffic lights with “identity” on the roster of power supply companies, the traffic management department pays for each light, one meter and accurate measurement;
For the electricity charges of traffic lights connected to other places, the power supply company shall settle with the responsible unit of the access place, and then with relevant departments:
For access to street lamps, the power supply company is to find the municipal settlement, which shall be paid by the finance;
If it is connected to other enterprises and public transformer stations, the power supply company shall settle accounts with the connected enterprises and stations, and then settle accounts with the traffic management department or municipal government;
In addition, due to historical reasons, traffic lights in some areas are connected to the surrounding public transformer station area. By estimating the line loss of traffic lights in the station area, the traffic management department will pay the electricity charge. In some places, power supply enterprises silently pay for the electricity bills of traffic lights!
In short, the electricity charge for traffic lights is paid by the public finance and paid by the state and taxpayers.
Will the traffic lights power off?
Of course, traffic lights will be powered off, which is usually related to two situations:
First, planned maintenance. In this case, the power supply company will send a power outage notice in advance.
For traffic lights with “status”, the power supply company clearly understands whether the planned maintenance will affect the operation of traffic lights, and will notify the traffic management department in advance to make preparations;
For those “black door” traffic lights, although it is difficult for the power supply company to understand which traffic lights will be affected by the power failure, it will also inform the customer manager, municipal department or traffic management department of each special transformer in advance, and make judgment and preparation according to the information they have
In addition, when the traffic lights fail, the general traffic management department will use the emergency traffic lights or send traffic police to assist at the intersection, while the power supply company will step up its operation to restore the traffic lights as soon as possible.
Does the traffic light consume electricity?
Although the power consumption of traffic lights is small, there are high requirements for power supply stability and great differences.
In addition to being closely related to the light source intensity, the traffic lights with single function and simple structure have low power consumption, while the traffic lights including “accessories” such as surveillance cameras and sidewalk indicators have high power consumption.
Most traffic lights use LED light source, which is more energy-saving than traditional incandescent lamps. Usually only when there is a power failure or power supply is really unavailable, the traffic police uncle will take out the solar traffic lights for emergency use~
After reading this article, I believe you already know the answers to the above questions
But after understanding the traffic lights
We should also abide by traffic rules
Cherish life and travel safely~
