Overview

The 36V safety seamless power busbar should be inspected every 1-3 months based on the usage of mobile electrical equipment. Focus on checking the wear of the collector brush. If the wear amount is ≥ 5mm, it must be replaced. If loose or worn electric brushes are found during inspection, the cause should be identified and dealt with in a timely manner

Product Details

36V safe seamless power busbar

1、 Product Structure: The sliding contact line power busbar is composed of guide rails, sheaths, collectors, hangers, connectors, fixing clips, end caps, etc. It can also be configured with expansion sections (thermal compensation devices), maintenance sections (isolators), etc. according to user requirements.

2、 Guide rail and sheath: The guide rail is made of aluminum alloy profiles with good conductivity and strong environmental adaptability (grade 6063, status T5). The lower part of the guide rail is embedded with a "V '- shaped stainless steel groove to ensure wear resistance, stability, and good contact of the collector brush when sliding along the groove. The guide rail is generally fixed to a length of 6 meters. The sheath is composed of engineering plastics with toughness, abrasion resistance, anti-aging and flame retardancy, which has a good insulation protection effect on the guide rail and ensures personal safety.3、 Collector: The collector is a supporting structure and is the main component that supplies power to mobile devices. Composed of specially designed carbon brushes, terminal posts or terminals, plastic covers, support arms, etc. Apply appropriate contact pressure, slide smoothly along the guide rail, and supply power to the equipment. When the equipment needs maintenance, the carbon brush of the collector can be pulled away from the guide rail to cut off the power, ensuring safety and facilitating operation.4、 Connector (also serving as a power supply): The connector is the end connection between guide rails, reliably connected by pressure plates and bolts, and the housing is made of engineering plastic as a protective cover. A protective cover that also serves as a power supply, with a port for introducing power supply lines, and is fastened together with the connector pressure plate and bolts.

1. Sliding contact wire conduit: It is a semi enclosed shaped tubular component that is the main part of the safety sliding contact wire. It can be embedded with 2-9 guide rails as power supply wires as needed, and each guide rail is insulated from each other and from the outer shell to ensure the safety of power supply. And effectively prevent electric shock accidents for maintenance personnel during live maintenance. The length of each produced conduit is 6m, and it can be connected to any desired length. Generally, conduits are made in straight lines, but can also be made in circular arcs according to special requirements.

2. The sliding contact wire conductor is a set of brush housing frames that run inside the conduit. The sliding contact wire is driven by a fork (or traction chain, etc.) placed on the electrical mechanism (such as a crane, trolley, electric hoist, etc.) to synchronize with the motor, transmitting the electrical energy of the sliding contact wire brush through the guide rail to the motor or other control components. The number of poles of the conductive electric brush is 3-16, corresponding to the number of guide rails in the conduit.

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.

After determining the operating current of the system, the coefficient (K) is determined based on the ambient temperature (Ta) and the duty factor of the train. The actual allowable current of the guide rod is I=nominal current x K. It is necessary to choose a guide rod with a specification where I is greater than the actual operating current of the system.

Sliding contact busbarMaintenance and upkeep:

In order to ensure the normal operation of the sliding contact line and extend its service life, regular maintenance should be carried out after the sliding contact line is put into operation.

1. Electric brush: It should be checked every 1-3 months according to the usage of mobile electrical equipment. Focus on checking the wear of the collector brush. If the wear amount is ≥ 5mm, it must be replaced. If loose or worn electric brushes are found during inspection, the cause should be identified and dealt with in a timely manner.

2. Collector: Check at least once every quarter. Focus on checking whether the fasteners are loose, displaced, and whether the plastic and moving parts are worn. Check the spring tension (the contact pressure between the collector brush and the guide rail should be maintained at a certain pressure (see the table below). Discover problems and handle them promptly.

3. Connectors: Check at least once a year. Focus on checking whether the fastening bolts, welds, and supporting components are loose, corroded, or displaced. If any problems are found, they should be dealt with in a timely manner.

4. Daily inspection: Focus on checking the flatness of the track for any significant deviation (greater than 20mm), misalignment, insulation protection components for detachment, breakage, or damage, and stainless steel "v" grooves for any warping; Are there any foreign objects or conductive dust on the track. If necessary, the insulation resistance should be checked to ensure it meets the requirements (phase to phase insulation resistance should be ≥ 5M Ω).

Especially for environments with significant deviations in track alignment, gauge, inclination, frequent use, excessive workshop dust, high temperature, water, acid, alkali, fog, and outdoor use, it is necessary to strengthen daily inspection and maintenance.
