Darui Electric recommends for you
The shell of the single-pole sliding contact line power transmission device is made of wear-resistant and corrosion-resistant engineering plastic, which has strong insulation and a certain degree of protection. Its built-in conductor is made of copper or aluminum alloy, which can conduct electricity and serve as a guide rail. Multiple guide rails are integrated into one conduit, and a rolling trolley that maintains constant pressure contact with the guide rails supplies power. There is a convex groove behind the conduit, which ensures that the brush pressure of the sliding contact line conductor is not affected by the movement or rotation impact of the trolley. The brush of the sliding line conductor is a copper-graphite mixed product with high copper content and arc suppression function, and it has good self-lubricating performance. When the brush of the sliding line conductor moves and contacts within the single-pole sliding contact line guide rail, their friction does not produce electric arcs, and the structural design has strong safety.
The single-pole sliding contact line conductor is divided into single-rod single-head safety sliding line conductor and single-rod double-head sliding line conductor. When the rated current of the entire single-pole sliding contact line power transmission device is large, the single-rod double-head sliding line conductor can be used. Generally speaking, the single-rod double-head safety sliding line conductor can withstand twice the current of the single-rod single-head sliding contact line conductor. The maximum operating speed of the single-pole sliding contact line collector produced by Shanghai Yibao Company is generally 600 meters per minute, its contact pressure is about 27N, its lateral movement distance is about 100MM, and the movement distance in the contact direction is about 40MM. The main accessories of the sliding line conductor are carbon brushes, brackets, springs, etc. The carbon brush is installed on one end of the rotating arm of the collector through a fixing frame, and the other end is connected to the mobile equipment. Power is transmitted through movement. The collector produced by Shanghai Yibao has the advantages of no wire dropping, no electric erosion, low failure rate, long service life, safety and reliability, and is suitable for various types of mobile equipment.
1. Product Introduction
The HXPnP, R-H type protective safety sliding contact line has a conductive主体 of "H"-shaped aluminum profile, hence it is also called "H"-type energy-saving sliding line device. Energy saving is relative to the sliding contact line with angle steel as the main body, and the loss of electrical energy during transmission is greatly reduced. The resistivity of aluminum is much lower than that of steel, and its specific gravity is small. Rolling aluminum into an "H" shape is to improve overall rigidity and strength while ensuring a certain conductive cross-sectional area. However, the surface hardness of aluminum is low and it is not wear-resistant. In order to make the aluminum base material meet the practicality of being a conductive sliding contact line, the "H"-shaped middle beam is made into an upward arch shape, and wear-resistant stainless steel profiles are embedded here according to the specified process. This "H"-shaped stainless steel profile serves as the friction and transmission surface for the conductive block in the conductor. Its embedding process ensures the close combination of stainless steel and aluminum profile. The current introduced from the aluminum profile passes through the stainless steel body, and the conductive block in the conductor that maintains contact with it transmits the current out during friction contact, ensuring the continuity of current during the operation of the crane.
