Why does the leakage of street lights electrocute people after rain?

The main reason is the step voltage, the voltage of the grounding point should not be understood as 0, the landing point is the same as the potential of the live wire, the current will flow from the landing point of the wire to the earth, so the ground is centered on the wire landing point, forming a potential distribution area, the farther away from the landing point, the more dispersed the current, and the lower the ground potential. If people or livestock stand within 8 10 meters of the landing point of the power line. Electric shock may occur.

I think the question you asked is whether the voltage between the wire and the contact point is 0, but in fact, this electromotive force should be equal to the electromotive force of the wire, and it can only be understood as 0 until the depths of the earth. This is directly related to soil resistivity!

Soil resistivity is an important factor in determining the resistance of the grounding body, you can understand the earth as a large resistance, and the voltage can only be 0 when the resistance is large enough, so when the distance is very close, the voltage still exists, unless the soil resistivity is infinite.

Supplement: What is the voltage drop from the neutral line of the circuit to the ground or the distance of the test point, as long as the distance is greater than a certain distance, because the grounding point of the neutral line of the circuit is actually the neutral point of the low-voltage side of the transformer, so the voltage of the neutral line is generally 0 when you test on the road. If you test at the root of the neutral line, which is the neutral point of the transformer, the voltage will not be 0!

UWX Huaneng Sunshine is a manufacturer specializing in the production and development of instruments and meters, high-voltage experimental equipment, power equipment, power appliances, wires and cables, household appliances, electronic components, aluminum alloy boxes, high and low voltage complete sets of equipment, automation control equipment, and electronic components.

Specifically, you can take a look at Wuhan Huaneng Sunshine Electric to enter their ** to understand. ott

Specifically, it depends on the connection method in the street lamp pole, if the traditional way is used in the form of tape wrapping, it will be easy to age and fall off after a long time, coupled with rain, and extreme weather will be more prone to leakage, if it is installed with a well-sealed leakage-proof connector, it will be safer.

No, the protective measures are well done.

Legal Analysis: The Electricity Bureau and the Highway Administration Department should jointly bear the liability for compensation. Whoever owns the street lamp should be responsible.

That is to say, who is responsible for the management of the street lamp accident, who is responsible. Of course, this is subject to the determination of liability in accordance with the law. If it is because of the product quality of the lamppost, you can see whether the manufacturer is indicated on the lamppost, and you can use it to investigate the product quality responsibility of the manufacturer.

Legal basis: Article 1253 of the Civil Code of the People's Republic of China Where a building, structure or other facility and its shelving or hanging objects fall off or fall and cause damage to others, and the owner, manager or user cannot prove that he or she is not at fault, he shall bear tort liability. After the owner, manager or user makes compensation, if there are other responsible persons, they have the right to recover from the other responsible persons.

On a rainy day, if the road chong chain light falls, there will be a certain probability of leakage, and this is indeed a certain probability of leakage, so it is best to avoid a little bit of caution.

If you encounter this situation in the summer, you should not use your hands to contact the side answer, otherwise it will form a path with the earth, and you should take a wooden squire or find a professional to repair it.

Legal Analysis: Responsibilities of the Street Lighting Administration.

Legal basis: Construction Law of the People's Republic of China

Article 60 of the ninth article of the project supervision unit and the construction unit or construction enterprise collusion, fraud, reduce the quality of the project, ordered to correct, fine, reduce the qualification level or revoke the qualification certificate; where there are unlawful gains, they are to be confiscated; if the loss is caused, it shall be jointly and severally liable for compensation; where a crime is constituted, criminal responsibility is pursued in accordance with law. If the project supervision unit transfers the supervision business, it shall be ordered to make corrections, confiscate illegal gains, and may be ordered to suspend business for rectification and reduce the qualification level; where the circumstances are serious, the qualification certificate is revoked.

Article 72 Where a construction unit violates the provisions of this Law and requires an architectural design unit or a construction enterprise to violate the quality and safety standards of the construction project and reduce the quality of the project, it shall be ordered to make corrections and may be fined; where a crime is constituted, criminal responsibility is pursued in accordance with law.

Article 73 If the architectural design unit fails to design in accordance with the quality and safety standards of the construction project, it shall be ordered to make corrections and be fined; If the project quality accident is caused, it shall be ordered to suspend business for rectification, reduce the qualification level or revoke the qualification certificate, confiscate the illegal income, and impose a fine; if the loss is caused, it shall be liable for compensation; where a crime is constituted, criminal responsibility is to be pursued in accordance with law. Article 74 Where a construction enterprise cuts corners in construction, uses substandard building materials, building components and equipment, or has other acts of construction that are not in accordance with the engineering design drawings or construction technical standards, it shall be ordered to make corrections and imposed a fine; where the circumstances are serious, order a suspension of business for rectification, lower the qualification level, or revoke the qualification certificate; If the quality of the construction project does not meet the specified quality standards, it shall be responsible for rework and repair, and compensate for the losses caused thereby; If a crime is constituted, the criminal bridge shall be investigated for responsibility in accordance with law.
