How are the street lights on the road connected, our one is broken, and there is a section of the st

Street lights on the road are usually connected together by cables. Each street light has a power connector that connects to the grid via a cable to get power**. When a street light is broken, it may cause a section of the street light to be lit up.

First of all, when a street light is broken, it may be due to a burned-out bulb or a faulty circuit. In this case, the power connector of the street light will disconnect the current**, causing the street light to not work properly.

Secondly, street lights on the road are usually connected in series. This means that the power interface of each street light is connected to the power interface of the previous street light, and so on until it is connected to the power grid. Therefore, when a street light is broken, its power interface is disconnected from the current**, which will affect the street lights behind it.

When a street light is broken, it may cause a section of the street light to be lit up. This is because the current between the street lights does not flow properly, resulting in the street lights behind them not working properly. In this case, it is necessary to repair the broken street light in time to restore the lighting of the entire road section.

The method of repairing street lights is usually carried out by professional maintenance personnel. They inspect broken street lights, determine the cause of the failure, and repair or replace them accordingly. After the repair, the streetlight's power connector reconnects to the grid, restoring current** and enabling the streetlight to work properly.

In order to avoid the situation that the street lights are not lit for a while, regular maintenance and inspection are necessary. In this way, broken street lights can be detected and repaired in a timely manner, ensuring the illumination effect of the entire road section. At the same time, if you find that the street light is broken, you can also report to the relevant departments for repair, so that it can be repaired as soon as possible.

In short, the street lights on the road are connected together by cables. When a street light is broken, it may cause a section of the street light to be lit up. The method of repairing street lights is usually carried out by professional maintenance personnel, who will check the cause of the failure and repair or replace it accordingly.

Regular maintenance and inspection is necessary to ensure the proper working of the street lights.

Mixed connection, a section of the road in series, and then a section in parallel.

1. On both sides of the road.

The street lamp embraced us with open arms like a mother.

2. A street lamp is like the light emitted by fireflies.

3. Street lamps are like guards in the dark, guarding a piece of light.

4. Street lamps are like the sun, spreading light and illuminating our way home.

5. The street lights on both sides of the bridge are shining, and in the dark night sky, it looks like a fire dragon passing through the sea.

6. The street lamps on both sides of the road are like old people guiding the way at night.

7. Street lamps are like tireless warriors, guarding the safety of passing vehicles and pedestrians without complaint.

8. The street lamps on both sides of the road are like wise men to help people find their way.

9. The street lamps on both sides of the road are like rows of athletes holding torches, ready to go.

10. The street lamps on both sides of the road are like lighthouses, guiding people forward.

Hello, the standard answer to this question is: the bright street lamps on the highway are like (a lighthouse in the dark sea, guiding us on the way home).

Just a broken street light on the road means: the street lights on the road are controlled in parallel, and a broken street light does not affect the work of other lights. strong>

Street lamp refers to the lamps and lanterns in the road lighting range in traffic lighting, which are composed of lamps, wires, light sources, lamp poles, lamp arms, flanges, and foundation embedded parts, and are widely used in various places that need lighting. Street lamps involve lighting technology, suitable for street street lights, the purpose is to design a long life, low power consumption, high power factor, small current harmonic content of high-efficiency electronic energy-saving street lamp.

Answer B Question Analysis: When one of the street lights on the road is damaged, the others are still glowing, so they are connected in parallel, and the reason why they are on together and dark together is that a trunk switch is used

Therefore, choose B test center: This question examines the identification of series and parallel circuits.

Comments: There are two basic connection forms of the circuit: one is in series, and the other is in parallel In the series circuit, there is only one path for the current, and the electrical appliances affect each other;

In the parallel circuit, there are multiple flow paths of current, and each electrical appliance works independently without affecting each other

When one of the street lights on the road is damaged, the others are still glowing, so they are connected in parallel, and the reason why they are on together and dark together is that a trunk switch is used

Therefore, choose B

Question B analysis: When one of the street lights on the road is damaged, the others are still glowing, so they are connected in parallel, and the reason why they are bright together and dark together is that a trunk switch is used

Therefore, choose b Comments: There are two basic connection forms of the circuit: one is in series, and the other is in parallel In the series circuit, there is only one path of current, and the electrical appliances affect each other;

In the parallel circuit, there are multiple flow paths of current, and each electrical appliance works independently without affecting each other

The street lights on the road are on and off at the same time, but when one light is broken, the other lights can be turned on, so the various electrical appliances in the parallel circuit do not affect each other: the street lights are connected in parallel

So the answer is: and

It's a parallel circuit! Copy.

1. If it is in series, as long as the filament of one lamp is burned.

The other lights won't shine! In parallel circuits, electrical appliances can work independently and do not affect each other, even if one lamp is broken, it will not affect the light of other bulbs!

2. Generally, the rated voltage of the bulb is 220V, and only parallel connection can meet the requirements; And if it is connected in series, it has a partial voltage effect, the more bulbs in series, the lower the voltage at both ends of the bulb, and the darker the bulb will be!

The simultaneous extinguishing of parallel connection is due to the time control switch of the street lamp.

In parallel, if one is broken in series, it will be lit, and a master switch in parallel.
