DMHP-4-95/270 Multipole Tube Sliding Contact Line Delivery Location

DMHP-4-95/270 Multipole Tube Sliding Contact Line Delivery LocationMulti pole tube sliding contact line collector, also known as receiver, conducts the current on the sliding contact line to the electrical equipment through the collector. The collector is installed on the collector bracket, which is installed on the moving equipment. As the device moves, the carbon brush on the collector moves within the sliding wire, achieving uninterrupted power supply. To facilitate the slip of the collector brush and reduce brush wear, a copper sleeve with a 45 degree chamfer is embedded at the root of the brush; At the same time, in order to make the current collector move flexibly and conveniently, bearings were installed in the guide wheel.

1. Sliding contact wire safety: The power supply safety sliding contact wire housing is made of high insulation performance engineering plastic. The protection level of the shell can reach IP13.IP55 as needed, which can protect against rain, snow, frost, freezing attacks, and foreign object contact. The sliding contact line has experienced various environmental conditions. Good insulation performance, no harm to maintenance personnel touching the outside of the transmission conduit.

2. Reliable sliding contact line: The transmission guide rail has good conductivity, fast heat dissipation, high allowable current density, low impedance value, and small line loss. Electric brushes are made of metal copper and carbon alloy materials with high conductivity and wear resistance. The conductor is flexible in movement and has good directional performance, effectively controlling contact arc and series arc phenomena.

3. Sliding contact line economy: The power supply safety sliding contact line device has a simple structure, high allowable current density, low resistivity, low voltage loss, and can save about 10% of electricity. It realizes the use of plastic instead of steel and copper, with a novel design that does not require other insulation structures or compensation lines. It is installed on the same side of the crane control room. Sliding contact lines save installation materials and costs.

4. Convenient sliding contact line: The power supply safety sliding contact line device integrates multiple pole busbars into one conduit, making assembly simple. The fixed bracket, connecting clip, and suspension device of the sliding contact line are all supplied as universal parts. Assembly, disassembly, adjustment, and maintenance are also very convenient.

The different types of alloy elements contained in copper bars are divided into two types: ordinary copper bars and special copper bars. There are two types of copper bars according to their organization: α and (α+β). Due to the harmful effects of lead, alpha copper bars have low high-temperature plasticity and can only undergo cold deformation or hot extrusion. (α+β) Purple copper has good plasticity at high temperatures and can be forged. Beryllium bronze is a beryllium copper based alloy (Be0.2-2.75% wt%), which is one of the most commonly used beryllium alloys and accounts for over 70% of the total beryllium consumption. Beryllium bronze is a precipitation hardening alloy with high strength, hardness, elastic limit, and fatigue limit after solution aging treatment. It has small elastic hysteresis and corrosion resistance (corrosion resistance rate of beryllium bronze alloy in seawater: (1.1-1.4) × 10-2mm/year). Corrosion depth: (10.9-13.8) × 10-3mm/year. ）After corrosion, the strength and elongation of beryllium bronze alloy remain unchanged, so it can be maintained in water for more than 40 years. Beryllium copper alloy is an irreplaceable material for submarine cable relay structures. In sulfuric acid medium: Beryllium bronze has an annual corrosion depth of 0.0012-0.1175mm in sulfuric acid with a concentration of less than 80% (room temperature), and corrosion accelerates slightly when the concentration is greater than 80%. Wear resistant, low temperature resistant, non-magnetic, high conductivity, impact spark free, and other characteristics. It also has good fluidity and the ability to reproduce fine patterns. Due to the various properties of beryllium copper alloy, it has been widely used in the manufacturing industry.
