Brief Analysis of Related Applications of Safety Sliding Contact Line

    

　　Advantages, Disadvantages, and Improvements of Safety Sliding Contact Line in Application

　　Safety Sliding Contact Line  is a new type of mobile power supply device, which gradually replaces the old exposed angle iron and copper bar sliding contact lines with its superior performance such as insulation, safety, temperature resistance, vibration resistance, and energy saving. The safety sliding contact line uses smooth and flat T2 copper bars filled in engineering plastic tubes or trough plates, or aluminum profiles embedded with wear-resistant conductors as current-carrying conductors, combined into a power transmission conduit. There is an open slot under the conduit to facilitate the operation of the current collector, and the high wear-resistant copper-based graphite brush of the current collector guides the electric power to the working electrical equipment.

　　The use of the safety sliding contact line brings safety to the workshop, but it also has disadvantages. Bridge cranes are prone to power failure during use, and sometimes sparks are generated in the power transmission conduit. In severe cases, the sliding contact line may "explode" at a certain point, causing frequent replacement of the current collector and affecting production.

　　To this end, the following improvements have been made to the safety sliding contact line: increase the chamfer of the current collector brush and polish it smooth; increase the strength and elasticity of the springs between two opposite brushes of the current collector to ensure the springs recover freely; deepen and reinforce the spring seat in the current collector to ensure that the recovery spring of the brush is not easy to "displace" during work; the connecting block at the joint of two sections of the safety sliding contact line should have a chamfer to ensure smooth transition of the current collector. At the same time, to ensure the normal use of the safety sliding contact line, standardized operation by crane operators, regular maintenance by maintenance workers, and regular inspections are also essential.
