Safety wire - for dust, moisture and other environments, can be equipped with dust seals and hand protection (When the trolley wire is close to people, it must be protected by hand, such as: akapp). The collector operates at a speed of less than 300 meters/minute.
Multi-pole sliding wire - easy to install, fast, simple and compact structure, safe and reliable, suitable for current below 100A commonly used
Rigid Body Sliding Line - for high current equipment, up to several thousand amperes, adaptable to harsh environments, high temperatures
Unipolar trolley wire - combined according to different number of poles, the current can reach 1000A. It is the most commonly used trolley wire at present.
Sliding line quality can be based on the following standard constants:
1, carbon brush life - is a consumable, travel distance affect the equipment maintenance cycle.
2, the quality of the slide wire shell - thickness, hardness, applicable temperature, environment and so on.
3, collector performance - mainly from the wheel life, turn wheel design and whether the collector meets a variety of environments.
4. Scaling line expansion problem - The expansion problem should be considered after the length exceeds 100 meters.
5, voltage drop problem - according to the length of a variety of copper strip voltage drop varies.
In order to ensure the normal operation of the trolley line and prolong its service life, after the trolley line is put into operation, it should be regularly inspected.
1. Brush: It should be checked every 1-3 months according to the use of mobile power equipment. Focus on checking the wear of the collector brush. If the wear is â‰¥ 5mm, it must be replaced. If the brush is found to be loose or if the wear deflection occurs during the inspection, the cause should be ascertained and dealt with promptly.
2. Collectors: Check at least once every quarter. Check the fasteners for looseness, displacement and wear of plastic parts and moving parts, check the spring tension (the contact pressure between the collector brushes and the guide rails should maintain a certain pressure (see the table below). Find problems and deal with them in time.
3, connectors: at least once a year inspection. Focus on checking whether the fastening bolts, welds, and supports are loose, rusted, or displaced. If any problems are found, handle them in time.
4. Daily inspection: Check whether the straightness of the track has obvious deviation (greater than 20mm), misalignment, whether the insulation protection parts are detached, broken or damaged, whether the stainless steel â€œvâ€ groove is tilted, and whether there is any foreign matter on the track. And conductive dust and so on. If necessary, check whether the insulation resistance meets the requirements (interphase insulation resistance should be â‰¥ 5MÎ©).
In particular, it is necessary to strengthen day-to-day inspections and maintenance for vehicles with large deviations in track alignment, track distance, and inclination, frequent use, excessive dust in workshops, high temperatures, and water, acid, alkali, fog, and outdoor use environments.
