What is the relationship between the switch and the patch panel?
This is a physical about the conductive problem, the sparrow standing on the wire is two feet at the same time to seize the wire, if it is a single foot then it will because of the high voltage of the voltage to death, it is said to burst, because the sparrow feet standing wire On its feet as a pair of two electrodes through its body quickly and was everywhere, single-handed, then it is a conductor, the current nowhere to export
Because the bird is small, it only touches a wire, its body and the root of the wire that is standing in parallel can also think that the wire shorted the birds, the body without the current through, so they will not be electric shock. The following is a concrete calculation to illustrate the problem: the original, the birds of the two claws are standing on the same wire. Conveyor .000 volts of high-pressure LGJ-type ACSR with a cross-sectional area of ??95 mm2 and a permissible current of 325 amps. If the distance between the birds and the claws is 5 cm, this 5 cm long wire resistance is only 1.63 × 10-6 ohms, the voltage U = IR at both ends, no more than 5.3 × 10-3 volts. This is the voltage applied to the bird. If the resistance of the bird's body is ohm, then the current through the bird's body is only 0.53 microamps. The current is very weak, so the birds will not be electric shock. However, if the snake climbed the wire on the dangerous, and its body longer, when it climbed to the high voltage line will be the line of fire and the two lines together to cause electric shock death. Drilling into the power distribution room of the mice are often electrocuted. We also know that the electrical workers in the high voltage line live work, that is, as the birds standing on a wire on the truth is the same, so to safe operation. Magpies and crows and other birds like the pole in the bar on the base, which is also very dangerous, it is easy to form a short circuit, causing disasters. However, if the birds stand on the wire, trying to peck the transmission tower, it would be a disaster. Because the voltage between the wire and the tower is very high, so do not wait for birds to contact the tower, high-voltage arc will burn it, but also due to short circuit caused by power outages. Therefore, people often install obstacles on the tower, do not let the birds peck into the tower.
