Can the ground wire of the appliance be connected to the lightning rod?
Usually we will each such wire called phase (fire), power transmission is usually to three-phase four line, three head of three-phase power is called phase, three-phase three tail connected with said neutral line is also called "zero line". The reason for the zero line is that there is no current in the neutral line at the time of the three-phase equilibrium, or that it is directly or indirectly connected to the earth, and that the earth's voltage is near zero. The ground wire is a reliable circuit for connecting the earth with the outer shell of the equipment or the electric appliance, and is a good scheme for preventing the electric shock accident. The line of fire is also called the phase line, and the utility model is composed of a zero line and a power supply circuit. In the low-voltage network, the three-phase four wire system is used to transmit power, among which there are three phase lines and one zero line. In order to ensure the safe use of electricity in the users zone to the power supply system with three-phase five line, the fifth thread is wire, one end of which is in the user area near the metal conductor buried deep underground, ground contacts and the other end of each user is connected to the grounding protection.
The lightning rod and ground are leading to the earth, but the lightning is the lightning to earth, general requirements for embedding depth requirements below 3 meters, and the main function is to guide the earth ground static, electric appliance housing to ensure safety. If the grounding and lightning together, may lead to the lightning room or household appliances, to damage and even cause fire. Ground wire zero line, in order to make the AC have a very convenient power conversion function, usually industrial electricity, three sinusoidal alternating current. The current phase (which reflects the direction and magnitude of the current) varies 120 degrees from each other.
Lightning is lightning lightning once used, if you click the washing machine, brother. General washing machine can not grounding, as usual, as long as your environment is not particularly wet ground, is dedicated to a single line in underground is different from lightning line, use two completely different. If the ground wire and the lightning rod are connected together, then the lightning may be brought to the computer room or household appliances, then it is not safe
