3) After the indoor ground construction is completed, mark the ground leveling line on the well wall.
4) The strength of the base and structure to reach the permissible device.
5) The decoration work that may damage the installed busway has been completed.
6) Anti-theft measures should be adopted locally related to densely packed bus devices.
2. Personnel selection and training before installation
1) The device, operation and protection of densely packed busbars should be carried out by professionals.
2) Professional workers should be aware of the device, structure, operation and hazards of the equipment: they should also be subjected to systematic training on how to power the equipment and conduct tests.
3. On-site delivery and equipment preparation
1) Check whether the products and accessories have arrived at the capital verification site, and draw up the installation plan.
2) Equipment required for densely packed bus device: 1000V insulation tester (recommended): 10-12, 17-19, 21-24 open end wrench, socket and torque wrench; Flat gentle cruciform screwdriver: horizontal: tape measure, hanging wire; Scaffold; Calabash; herringbone ladder; percussion drills; cutting machines; electric welding machine; bench drills; Copper processing equipment and temporary power supply.
4. Disassembly of bus bar and device operation
1) According to the final information acknowledged by the manufacturer orderer. Such as original graphics, trend charts, shoveling of obstacles and reserved positions.
2) Generally, the size of the reserved hole should be 50mm -100mm larger than the overall size of the bus duct. For special data, please refer to the drawing requirements.
3) The distance from the dense busbar to the wall and the pattern board is necessary to ensure that there is enough horizontal and gentle straight space in the installation and protection process.
4) Take precautions to avoid leakage, dust and heat sources from corrosive busbars.
5) Manufacture of dense busbar device hanger: first recognize the position, draw a thin line to simulate the direction, and then fix the device bracket. Note that it is necessary to recognize whether the fixture bracket is firmly fixed and does not damage the structure of the building.
6) Conduct an insulation test on the bus unit to be installed, and the test value can be installed within the qualified range.
7) When hoisting, please pay attention to personal safety and equipment safety precautions. Avoid personal injury and damage to dense busbars.
8) When the straight device is straight, there is generally no special situation from the bottom to the top of the section-by-section device; It is necessary to take appropriate protective measures against the installed busbars to avoid the incursion of foreign objects.
9) It is advocated that in the process of installation, before the busway is not used, the packaging can be retained on the busway, and the protection can be increased at the joint.
10) When articulation is carried out between busbar units, it is necessary to keep the appearance of the articulation device clean and the busbar pipes in the same straight line. Then tighten the bolts. Once the adapter is tightened, mark it with a paint pen to acknowledge tightening.
11) When the bus unit is connected to other equipment, it is necessary to completely disconnect the power supply, and it is necessary for the equipment to be reliably grounded.
12) In the process of installation, all plug-in interfaces of densely packed bus bars must be in a dry closed state, and plug-in box switches must be in a dry disconnected state. It is forbidden to plug or unplug the plug box when the power is on.
