Tianyi Electric introduces the overall working principle of trolley wires

The structure of the trolley line is various, but the general principle is as follows: Because the mobile device needs to change positions from time to time, the mobile device must be able to obtain the power supply at any time in different positions, otherwise it cannot continue to move.

At this time, the trolley line was born with several conductors laid in parallel along the running track of the mobile device, and the power was turned on. On the moving equipment, a current collector can be taken from the conductor.

In this way, when the device moves, the current collector operates synchronously with the device, and the power is obtained from the conductor at any time and provided to the device so that the device can continue to move. The device consisting of these conductors and current collectors is called a trolley wire.
