I don't know what happened recently. What should I do if the wires at home are short-circuited? How to do it well? Many people don't know how to check and solve the short circuit in their homes. Teach you a few tricks: First, how to check 1, first turn off all the electrical appliances in the house, and it is best to unplug the electrical appliances if they have plugs. 2. The live wire is short-circuited with the protection wire. Disconnect the master brake, disconnect the protection line of residents, and measure whether there is any connection between the live wire and the protection line of each socket with R* 100 meter. If so, it proves that the live wire and the protection wire are short-circuited. Open each socket and search one by one. Turn on your main switch again and see if it trips (see if your insurance burns first). 4. If you jump, the main line is short-circuited, then you can see if there is a short circuit at the joints of the main line or some turning places. There is a plug at home, which is also a place that is easy to short circuit. If you don't jump, turn on the household appliances one by one, turn on the lights one by one, and then plug in the appliances. When you open it, it will trip. That's a question of which line. Then check that line. 6. You can also turn on the power supply and then check the socket with an electric pen. Under normal circumstances, the fire wire will make the electric pen glow, and the zero wire will not glow. If both of them are found to glow, it means that the zero line here is broken. If both don't shine, it means that the fire line here is broken. 2. what should I do? 1. Disconnect the power. 2. Find the fault point. 3. Reconnect the wires and take insulation measures. 4. Measure whether there is a short circuit with a multimeter. 5. If there is no problem, you can send electricity normally. 6. First turn off the main power supply. If there is a three-phase short circuit, switch to the diode position with a multimeter to check whether there is a short circuit between items. If there is a short circuit, please check whether the wire sheath is burnt or fallen off. If it is a 220V short circuit! Check whether the three-phase items are short-circuited with the zero line, whether the cable insulation skin is aging or whether the insulation resistance is within the safety limit with a shaking table. If the motor is out of sync with other things, please repair the motor coil winding in time. If it is short-circuited in wet environment, please pay attention to using waterproof and insulation measures! Like a waterproof electrician. If the PCB circuit board is short-circuited, please cut off the power supply in time and hand it over to the technical department for handling. In another case, please distinguish between live wire and neutral wire. As if nothing happened, don't watch the sparks together. Dear, for the sake of safety, if you can't operate the above information, you'd better ask a professional expert, which is a good choice!
