Haikou streetlights have to pull in the rain

Haikou streetlights have to pull in the rain In summer in Haikou, there is a thunderstorm every afternoon. However, the people of Haikou can breathe a sigh of relief. They no longer have to worry about the leakage of rain from the streetlights, because the streetlights in Haikou have no electricity at all in the rain.

According to media reports, the person in charge of the street lamp management office of the Haikou Municipal Engineering Maintenance Company explained: “Because the street lamp cable is buried underground, there is a certain degree of difficulty in maintenance and inspection. In addition, the street lamp line has a cable inspection well, and most of the wells are located in street lamps. Near the green pond where the pedestal is located, once the accumulated water has flooded the green pond, it is prone to electric leakage and there is a large potential safety hazard. To avoid such accidents, in case of heavy rainfall, once the accumulated water has been found over 15cm above the road surface, it will Take measures to extinguish street lights."

Faced with the explanation of the streetlights, people secretly rejoiced. Fortunately, the street lights were only pipe lights. If they had all the power supply, wouldn’t the seaport have to be dark when it rained? If the traffic police also adopted such a precautionary measure, a heavy rain came and all the red lights were on. Fortunately, the traffic light is not the power source of the streetlights. Otherwise, the seaport is a little rainy.

The street light's cables are buried underground, which makes maintenance difficult. Nowadays, more cables are buried underground. Cable television, broadband cable, communication lines, gas pipelines, etc. Is the cable, probably more than streetlights? How can other lines withstand storms, except that the street lights have to be turned off? In addition to the brakes, there is no other way to prevent leakage in street lamps.

The street lights have an inspection well, which constitutes the reason for the street lamp leakage. However, all pipelines buried in the ground may have inspection wells. A few days ago, Haikou City Administration announced that there were 290,000 covers in the city, and it was not always a street lamp. Because there are inspection wells, but also because the inspection wells in the underground, the street lamp on the street lamp leakage is not sure, you have to switch off the power. In addition, is there no other way?

Once the accumulated water has flooded the green pool, it is prone to leakage. The people in the street lamp said that the people of the city had a cold sweat. In view of this, the leakage of street lights in Haikou is a stubborn disease that cannot be ruled even by street lamps. In addition to power cuts, they have nothing else to worry about. The fool looks at New Year next door. Can we send people out for a visit? Are other cities only having street lights in sunny days? Is it a rainy day that the street lights will be electrocuted?

In recent years, Hainan has been rectifying laissez-faire greed. People even think that this is only a matter for government agencies. Now that they have learned the explanations of the person in charge of the Haikou Street Lamp, it is understood that apart from the authorities, the service agencies have similar problems. . Let the street light wire do not leak electricity when it rains. I believe this is not the same high-tech technology as the space launch. As long as it is serious, it is completely avoidable. However, the Haikou streetlights do not manage their own one-and-a-half acres, or are too lazy to manage their own one-and-a-half-acre three-districts, and they will simply switch off and power off. Think about it, the best way to avoid a car accident is not to drive; the best way to prevent food poisoning is not to eat; the hospital prevents contradictions between doctors and patients and simply shuts the door off; the pool is flood-proof and it is not completely safe to drain. ?

In fact, if the people of Haikou are not going to rain on the road, the solution is very simple. This is an open recruitment. Who can solve the problem of rain and leakage of street lights? If you are big in the world, you don’t believe that you are not capable of being able. For those who are incapable of being able to do it, not the same as the personnel management system we have been pursuing, why not try the street lights?

A good laminate structure can control the characteristic impedance of the printed circuit board, and the traces can form an easily controllable and predictable transmission line structure called an impedance plate. The characteristic impedance of the conductor on the printed circuit board is an important indicator of the circuit design. Especially in the PCB design of the high frequency circuit, it must be considered whether the characteristic impedance of the wire and the characteristic impedance required by the device or signal are consistent and match.
