Working Principle of C15 Trolley Wire
Darui Electric recommends
Mobile equipment needs to constantly change positions due to movement, and at each different position, it must be able to obtain power supply at any time, otherwise it cannot continue moving. At this point, the C15 trolley wire comes into being. Several conductors are laid parallel along the running track of the mobile equipment and connected to the power supply. On the mobile equipment, a current collector that can draw power from the conductors is installed.
The C15 trolley wire device consists of two main components: the conduit and the trolley wire current collector, as well as some auxiliary components, as shown in the figure:
1、Trolley wire conduit: It is a semi-enclosed special-shaped tubular component and is the main part of the safety trolley wire. Inside, 2-9 bare guide rails can be embedded as power supply conductors as needed. Each guide rail is insulated from each other and from the shell, ensuring the safety of power supply. It also effectively prevents electric shock accidents for maintenance personnel during live maintenance. Each conduit produced by Xinxiang Yudong is 6 meters in length and can be connected to any required length. Generally, conduits are made in straight lines, but they can also be made into arc shapes or other special shapes according to specific requirements.
2、The trolley wire current collector is a set of brush frames running inside the conduit. The trolley wire is driven by a fork (or traction chain, etc.) installed on the electrical mechanism (such as a traveling crane, trolley, electric hoist, etc.), making it run synchronously with the electrical mechanism. It transmits the electrical energy from the guide rails and trolley wire brushes to the motor or other control elements. The number of poles of the current collector brushes ranges from 3 to 16, corresponding to the number of guide rails in the conduit.
