How the trolley works: Using the trolley's power supply system, the vehicle uses the electricity stored in the capacitor when traveling between stations, without connecting to the catenary. After arriving at the station, the vehicle uses the time when passengers get on and off the bus to raise the bow and charge (the actual charging time is much longer than the time when passengers get on and off the bus).

In terms of power supply, the rectifier station has widely used electronic computer automatic monitoring; In terms of vehicle power, AC drive technology has gradually replaced DC drive technology. In terms of overhead contact line, the high-speed overhead contact line hub that can adapt to the high-speed driving of vehicles has gradually replaced the old electromagnetic dividing and merging device.

Trolleybuses do not need to lay track and transform the road surface, and do not need to build a signal system, so the initial investment is low. Compared with electric vehicles, it can greatly reduce the amount of expensive power batteries or fuel cells, and also reduce its own weight. In practice, the vehicle can be charged in real time through the contact line, and the driving distance is not limited by the battery power or fuel load.

Saves the bus vehicle due to charging or refueling empty driving distance; Not limited by the track, in the event of traffic congestion or sudden accidents, flexible scheduling can be carried out to a certain extent, and the double-acting trolley bus can even reach the degree of flexibility of the car.
The trolley bus has a divider on the overhead line before the turn divider. The principle of the splitter is that the energized coil generates an electromagnetic field to close the line. Pay attention to the driver, the trolleybus in the exercise to the line divider, the driver's operation is not the same, to divide the line, the driver will step on a switch, do not divide the line, the driver will not step on the switch, let the car slip over the line. When the driver steps on the switch, the coil in the spliter senses a changing current, and the changing current generates a changing electromagnetic field, triggering the electromagnet to work, closing the spliter line, and the trolley's braid will follow the closed line.
A Trolleybus is a type of road public transport that is usually powered by overhead contact lines, driven by electric motors, and does not rely on fixed tracks. In some countries or regions (such as Japan), trolleybuses belong to the category of rail transit.
In general, the trolley bus will lose power when the receiving pole is disconnected; Double-acting trolleybuses equipped with power batteries, supercapacitors or diesel generators can operate offline in sections without overhead catenary.

The trolley bus does get its power from the overhead catenary, so it needs two pantographs, one for the live wire and one for the neutral wire. The overhead contact line used by all trams is bare wire, otherwise how to get electricity.
