The sliding contact line is mainly used for power supply. The sliding contact line device can be used for electric hoist, electric beam type and electric single beam bridge crane; stacker, automatic testing line for electromechanical products, automated production line, mobile power tools and other mobile power receiving Equipment, as well as the fixed laying of bus ducts in factories, mines, workshops and offices.
Sliding contact wires are becoming larger and larger in modern production. Now sliding contact wires are mainly used in power supply systems in life. They are a must-have product for power supply systems. However, the time of installing sliding contact wires must be strictly in accordance with Installation sequence, ensure the safety of installation to ensure the safe use, so the installation acceptance step is essential.
Acceptance criteria for sliding contact line installation:
First, the bracket
1. It should be treated as antiseptic.
2. It should be continuously welded.
3. The installation is firm, and the positions of the mounting holes are the same.
Stand spacing
Single-line "H" type below 300A ≤ 1.5M, above 400A ≤ 3M.
Multi-line no-slip sliding contact line type 1.0-1.5M.
Catheter type 1.0-1.5M.
Cable slip models 1.0-2.0M.
The distance between brackets of arc segments should be less than 1.0M according to the site conditions.
3. Suspension parts: correct position, firm installation, compound quantity requirements.
The main body of the sliding contact line
1. The gap between the protective shell and the conductor is ≤ 2mm.
2. Straightness: ± 15mm from the height of the track center.
3. Straightness: ± 15mm longitudinal tolerance from track center.
4. Distortion: 15mm / 10m.
Five, retractor:
1. The quantity meets the requirements.
2. The gap distance should meet the theoretical expansion and contraction caused by the large temperature difference at the installation site.
6. Current collector
1. The square steel frame is welded firmly, and the vertical tolerance between the center line and the sliding contact line is ± 3mm.
2. The dimensions of the square steel bracket and the sliding contact wire should ensure that the collector's movable arm is parallel to the main body of the sliding contact wire, with a tolerance of ± 3mm.
3. The plane of the current collector and the contact line slides smoothly and meets the prescribed pressure.
7. Fasteners: The torque for tightening the nut should meet the recommended value of the manufacturer.
Eight, power supply line: the end of the line is firm and must not bear the tensile force.
