?Steel slide wire current collector? is an important component in the slide wire system. It is mainly used to directly conduct electric power to electrical appliances through the sliding contact between the carbon brush and the slide wire, so as to realize the mobile power supply function of the system.
Structure composition and working principle
The steel slide wire current collector is mainly composed of two parts: the tension device of the mechanical structure and the current collecting brush that directly slides and contacts the guide rail. The function of the tension device is to ensure that the sliding contact pressure between the current collecting brush and the guide rail is maintained at an appropriate level, and at the same time ensure the stability of the entire mechanism. The current collecting brush is the conductor that slides and contacts the guide rail to pick up electric energy. Its performance, conductive quality and the pros and cons of material structure and composition will directly affect the safe operation quality of the entire system equipment.
Types and characteristics
There are various types of steel slide wire current collectors, including single-brush and double-brush types, as well as front-mounted and side-mounted types. Different types of current collectors are suitable for different installation requirements and environmental conditions. For example, pure graphite current collectors have strong lubricating performance and are suitable for the situation where the contact surface of the slide wire copper rail is uneven, but the replacement frequency is relatively high; copper plate current collectors have a long service life, but sparks will be generated when encountering uneven conditions; alloy carbon brush current collectors combine the advantages of the first two, run smoothly and have a moderate service life, but the production cost is relatively high.
Application scenarios
Steel slide wire current collectors are widely used in mobile power supply for various cranes and electric hoists in industrial and mining enterprises, such as power plants, steel plants, petrochemical plants, automobile factories, ports and wharves, machinery manufacturing plants, shipyards, paper mills, textile mills, vehicle factories, railways, grain mills, wineries, chemical plants, home appliance manufacturing plants, warehouses and freight yards, etc. Its characteristics include strong adaptability, high reliability, good electrical conductivity, high temperature resistance, corrosion resistance, etc.
