Busway (referred to as busway) is a busbar system composed of metal plates (steel plates or aluminum plates) to protect the shell, conductive bars, insulating materials and related accessories. It can be made into a plug-in closed bus with plug-in junction boxes at intervals, or as a feed-in type without a junction box in the center ...

Busway is a conductive equipment used for current transmission, and now the higher the building is built, the more the application of busway is required, and in many large foremen, the use of busway is also very economical and reasonable. Any machine is made up of different parts, then the busway is made up of ...

(1) Single bus wiring. Single bus wiring has the advantages of simple and clear, less equipment, less investment, convenient operation and expansion, but its reliability and activity are poor. When the bus or bus divider is faulty or overhauled, it is necessary to disconnect all power to the bus. ...

Bar switches are different from regular switches. They are critical to ensuring effectiveness. For example, when the current exceeds a certain amount of time, they cause heat to be generated, allowing the fuse to switch the fuse to further assist in breaking the circuit. Therefore, as a kind of current protection device, they can achieve ...

Although the service life cost of the bus system is usually lower than that of the traditional wiring method, the bus system still bears a considerable cost compared with other structural elements of the water supply and drainage or HVAC system. In addition, customized busbar equipment allows the busbar system to be routed around obstacles ...

(1) Air-type busway Since the mid-50s of the last century, represented by Beijing Baizhifang Airport Electrical Appliance Factory, the conductive row has been supported in the shell with insulating liner and insulated by air medium. The phase-to-phase distance is 50mm. (2) Secret ...

The Wiener comb busbars and connection terminals are available with QUADRON®CrossLinkBreaker in size 000/00 Recommended installation: Wire entry at the lower end of the NH-fuse disconnector through the comb busbar. In the mounting position ...

1. It has a modern beauty; 2. Small dimensions; 3. Strong and light weight, simple operation; 4. The connection is very simple (just like connecting water pipes, connecting sections through tees, elbows and other joints to make them into a system; ...

1. The insulating medium is different: there is a certain open space between the copper bars of the air bus duct, that is to say, the insulation between the copper bars mainly depends on air, and the insulation medium between the copper bars of the dense bus duct (many people call it a closed bus duct) is an organic insulating material. 2. Copper bar placement ...

The bus system plays a very important role in the practice of construction, and for products such as the bus system, the relevant items can not be ignored, so that we can better use the practical value of this type of product. Generally speaking, when we are purchasing a bus system ...

1. Crevice corrosion When there is a gap between the surface of the tubular bus itself and other things, the corrosion in the gap will be accelerated due to the difference in the effect of the inflatable battery, but there is no effect on the outside of the gap. However, crevice corrosion has little to do with the type of alloy, because even very corrosion-resistant ...

1. For the charging of the spare bus, when there is a bus tie circuit breaker, the bus tie circuit breaker should be used to charge the spare bus. At this moment, the maintenance device of the bus tie circuit breaker should be fully invested, and the relevant maintenance value and time limit should be changed to a smaller one, so as to facilitate the bus tie circuit breaker when there is a problem, the bus tie circuit breaker can quickly trip, cut ...

The use of insulated tube bus in China has a history of nearly 20 years, and it has made a historic contribution to reducing the layout space of the distribution bus and improving the reliability of the bus operation. There are many manufacturers who supply this product, and their production processes are uneven, and the differences in processes are mainly reflected in the ...

1. Comprehensive correction of bearings The comprehensive correction of the bearing includes the comprehensive and strict correction process of the damaged bearing after cleaning, dismantling, inspection, roller table grinding or replacement of inner and outer rings, new rolling element manufacturing/original rolling element grinding, rolling element replacement, assembly, clearance adjustment and inspection and packaging.

1. Whether the maintenance scale of the bus differential is confirmed, and whether the maintenance target is unchanged Generally, differential maintenance includes bus differential maintenance, transformer differential maintenance, generator differential maintenance and line differential maintenance. The basic principle of completing differential maintenance is the same, that is, each side or each ...

Ambient air temperature: turn off the busbar system to benchmark the ambient air temperature; Unless otherwise ruled, the manufacturer should give an additional current to shut down the busbar system at a base ambient air temperature of 35°C; If applicable, the manufacturer should give an additional coefficient k: (K1=1 at 35°C) in order to determine the size of the package.

1. Before the bus duct installation, it should be ensured that the electrical shaft, substation and distribution room, the decoration project of the place through which the bus duct passes, and the heating and ventilation project are all completed to ensure that the bus duct is not polluted. The reserved holes and embedded parts of the floor and wall should be embedded and reserved according to the position required by the design. The functions of the busway are single ...

The bus system divides the bus into hard bus and soft bus. The 60mm bus system refers to the three-wire or four-wire bus with a distance of 60mm. 1. In the 60mm bus system, the different cross-sectional areas of rectangular copper bars or special-shaped copper busbars such as 2T and 3T can be used to achieve the best classification of current intensity grades.

In order to ensure the safe and economical operation of the power system and its power generation, supply and electrical equipment, power grid users require voltage separation to operate in three ways: forward voltage regulation, reverse voltage regulation and constant voltage regulation. However, in the actual operation of the power grid, due to the change of active and reactive power output, the increase or decrease of the electrical load, the system wiring party...
