Can I turn on the air conditioner in lightning weather?

Don't turn it on, it is best not to turn on the air conditioner in thunderstorm weather; At this time, if the air conditioner is in a power-off state, the possibility of the motherboard being burned by lightning and rain will be minimized. Lightning has both electrostatic dynamic damage and high voltage damage. The high voltage generated by strong atmospheric movement can be instantly and strongly discharged through the power line or antenna (mainly long line) of the electrical equipment, resulting in breakdown (high voltage damage) or melting (power damage) of the electronic components inside the electrical equipment, and finally causing permanent damage to the electrical equipment. Moreover, the strong magnetic field generated by this high-voltage strong discharge sometimes generates high voltage in the transformers of some electrical appliances, which burns electronic components. Good electrical appliance manufacturers will take corresponding lightning protection measures when designing circuits and printed circuit boards. Lightning rods must be installed in high-rise buildings. Don't use electrical appliances when it thunders. Air-conditioning is one of the most vulnerable household appliances to lightning, because air-conditioning and refrigeration compressors are often installed outdoors, so it is easy to be directly struck by lightning. At the same time, lightning is introduced indoors, which burns out the main engine and even endangers other items. In thunderstorm weather, try to keep curtains away from air conditioning or flame retardant fabric curtains. According to the past lessons, curtains are the main media for the fire spread of window air conditioning. When using electric air conditioner for heating, you must remember to cut off the power supply of the electric heating part when you turn it off. There are two other factors that need to be considered in lightning protection of air conditioning. First, the compressor installed outdoors should be welded with the down lead of the building or the structural column reinforcement used as the down lead to prevent direct lightning strike; The second is to shield the indoor air conditioning host to prevent lightning current from invading. When it thunders and rains, stop using the air conditioner and cut off the power. Lightning protection strategy of household appliances In addition, different types of household appliances should take different lightning protection measures. Industry experts give the following suggestions: 1. Computer: cut off the power supply and network cable. Don't surf the internet when it thunders and rains, unplug the power socket and network cable to prevent the computer from being damaged by lightning and its own danger. 2. TV: Unplug the socket signal line. Install a lightning rod on the outdoor antenna of the TV set. Once struck by lightning, hundreds of thousands of volts of lightning will be transmitted to the TV through the TV antenna. If the signal line of cable TV is broken, it will also cause TV to be struck by lightning. It is suggested that in thunderstorm weather, it is best to unplug the TV socket and cable signal. 3. Washing machine: Avoid connecting with water pipes. Many families like to connect washing machines with water pipes. Therefore, the public should pay attention to whether the metal pipes on the roof of the building are connected with the lightning protection belt on the roof. It's best to stop using the washing machine and unplug the power socket when it thunders and rains. When not in use, it is best not to connect the washing machine with water pipes. 4. Solar water heater: install lightning protection device. Do not use solar water heaters when lightning strikes; Solar water heaters must be equipped with lightning protection devices (including lightning rod, lightning belt, down conductor and grounding device); The whole power circuit of solar water heater should be shielded, and lightning protection devices should be installed at the power switch. When lightning strikes, it is best to unplug the household appliances. If you don't watch TV, turn on the air conditioner, don't make wired calls, and have an outdoor antenna, unplug the antenna before lightning strikes. In addition, household appliances should keep a certain distance from the external wall of the building.
