Won't the Tram's Overhead Wires Detach?
1 Answers
Tram's overhead wires won't detach. Below is the relevant introduction: 1. Principle: The tram maintains its route through the contact between its wheels and the tracks. Simultaneously, the pantograph (the visible current collector) on the tram's roof connects the tram to the overhead wire, forming a power-receiving circuit to ensure the tram can draw electricity. 2. Reason for non-detachment: Continuous contact between the pantograph and the overhead wire ensures the tram doesn't disconnect from the wire. Additionally, since the pantograph is mounted on a movable bracket, this bracket is key to preventing the tram from detaching from the wire and also serves as the tram's power switch. When the bracket is raised, the tram's pantograph receives power; when lowered, the tram loses power.
