Working Principle of C15 Type Sliding Contact Line
Darui Electric recommends
Mobile equipment needs to constantly change positions due to movement, and at each different position, the mobile equipment must be able to obtain power supply at any time, otherwise it cannot continue to move. At this point, the C15 type sliding contact line came into being. Several conductors are laid parallel along the running track of the mobile equipment to connect to the power supply. On the mobile equipment, a current collector that can draw power from the conductors is also installed.
The C15 type sliding contact line device consists of two main components: the conduit and the sliding contact line current collector, as well as some auxiliary components, as shown in the figure:
1、Sliding contact line conduit: It is a semi-enclosed special-shaped tubular component and is the main part of the safety sliding contact line. Inside it, 2-9 bare guide rails can be embedded as power supply conductors as needed. The guide rails are 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 Xinyang Yudong is 6m in length and can be connected to any required length. Generally, conduits are made in straight shapes, but can also be made in arc shapes according to special requirements.
2、The sliding contact line current collector is a set of brush housings that run inside the conduit. The sliding contact line is driven by a fork (or traction chain, etc.) installed on the power-consuming mechanism (such as traveling crane, trolley, electric hoist, etc.), making it run synchronously with the power-consuming mechanism. It transmits the electrical energy from the guide rails and the sliding contact line 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.
