Rural lightning protection knowledge, what are the basic measures of lightning protection

The reasons for the frequent lightning strikes of villagers' houses are: First, in the process of rural housing construction, there is a lack of supervision and audit by relevant departments, resulting in the construction of rural houses is not scientific enough, and lightning protection facilities are often ignored. In addition, many farmers install tin water tanks, solar water heaters, or buildings similar to small iron towers above the top floor, which often do not have grounding and lightning protection facilities, which pose a safety hazard. Now all kinds of household appliances in rural areas are popular, some farmers in order to increase the reception effect of TV programs, the TV receiving antenna is erected above the roof more than ten meters above the roof, and mostly supported by bamboo poles, once there is a thunderstorm, the lightning electrode is easy to flash with the metal receiving antenna, and then introduced into the room by the antenna, resulting in the damage to the TV and other indoor facilities and personnel.

Second, the lightning protection safety inspection system is not perfect, and there is almost no inspection on lightning protection safety in rural areas, which directly leads to the fact that lightning hazards cannot be discovered and eliminated immediately. Third, many of the rural power lines and lines are introduced by the overhead support of electric poles in the relatively empty farmland, and the thunderstorm will be introduced into the room through these overhead power lines and lines after the lightning strikes on the empty farmland, resulting in damage to indoor equipment and personnel.

Rural houses should not casually set up metal antennas, wires, and iron wires for drying clothes on the roof. Not to mention the drying of clothes into the room, or in the indoor power cord, ** line, TV antenna and other metal wires, usually, lightning always along these lines into the room, if there is no protective facilities will cause harm (such as the need to lead the line must be away from the human body meters away).

Don't watch TV when it's thundering anymore.

1. Erect lightning cables.

2. Improve the insulation level of the line itself.

3. Use the top line of the triangular arrangement as a lightning protection line.

4. Strengthen the protection of weak points of insulation.

5. Adopt automatic reclosing device.

6. The iron foot of the insulator is grounded.

7. Prevent direct lightning strikes, install lightning rods to protect the entire substation building from direct lightning.

8. Incoming lightning protection. Install lightning protection wires in the 1-2km section of the incoming line to protect the line from direct lightning strikes, so as to avoid damage to the equipment along the lightning voltage along the substation.

9. Lightning protection of power distribution device. In order to prevent lightning shock waves from invading the substation along the high-voltage line and causing harm to the power transformer, a group of valve-type lightning arresters should be installed on each section of the bus of the substation, and should be as close to the transformer as possible.

10. Lightning protection of high-voltage motor. Use a good FCD type magnetic blow valve type arrester with good performance dedicated to protecting the rotating motor or a metal oxide arrester with a series clearance, and install it as close to the motor as possible.

In thunderstorms, you should try to stay indoors and close the doors and windows, try not to play, watch TV, surf the Internet, and cut off all dangerous power sources at home, outdoors, should avoid trees, telephone poles, high-voltage lines, etc., stay away from metal devices, and find lightning protection buildings or cars as soon as possible to take refuge.

Do not stay and swim on the surface and near the water during thunderstorms or engage in other water sports or activities.

It is not suitable to drive motorcycles and bicycles in thunderstorms, because they are prone to lightning strikes when moving quickly in thunderstorms.

The relevant meteorological department will issue a lightning level warning signal in advance before the lightning phenomenon, and remind relevant departments and individuals to take relevant lightning protection measures.
