Quality of bus bar fabrication equipment

With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, and the traditional cables as power transmission conductors can no longer meet the requirements in high current transmission systems. The busbar emerged as a new type of distribution wire. It fully demonstrates the superiority and safety and reliability of the busbar during high current transmission. While bus bars are popular in the market, people also attach great importance to the quality of bus bar manufacturing equipment. Because high-quality bus bar fabrication equipment is the guarantee of busbar quality. This article will tell you how to judge the quality of bus bar fabrication equipment .

This article contains the following:

1. The bus bar fabrication equipment must be strong enough to support its own weight

2. The bus bar fabrication equipment can be supported on the insulator or completely surround the insulator

3. Connection of switchboard and bus bar fabrication equipment

4. Various shapes allow a larger span between the bus bar fabrication equipment supports in outdoor electrical switch stations.

1. The bus bar fabrication equipment must be strong enough to support its own weight

The bus bar fabrication equipment must be rigid enough to support its own weight, the force exerted by mechanical vibration and possible earthquakes, and the accumulated precipitation under outdoor exposure conditions. In addition, thermal expansion caused by ohmic heating and temperature changes caused by environmental temperature changes, and magnetic force caused by large currents must be considered. To solve these problems, flexible bus bar fabrication equipment was developed, usually a sandwich of thin conductor layers. These need to be installed using structural frames or cabinets.

2. The bus bar fabrication equipment can be supported on the insulator or completely surround the insulator

The bus bar fabrication equipment can be supported on the insulator or can completely surround the insulator. The bus bar fabrication equipment can prevent accidental contact by means of a metal grounded enclosure or an elevation beyond the normal range. [2] The power supply neutral bus bar fabrication equipment can also be insulated, because there is no guarantee that the potential between the power neutral line and the safety ground will always be zero. The grounding (safety grounding) bus bar fabrication equipment is usually bare and bolted directly to any metal chassis of its shell. The bus bar fabrication equipment may be encapsulated in a metal casing in the form of a busbar or a busbar, an isolated phase busbar or an isolated phase busbar.

3. Connection of switchboard and bus bar fabrication equipment

The distribution board divides the power supply into individual circuits in one location. Bus duct or bus duct is a long bus bar manufacturing equipment with a protective cover. bus bar fabrication equipment can be connected to each other by bolting, clamping or welding, and can also be connected to electrical equipment. Instead of branching from the main power source at one location, new circuits are allowed to branch anywhere along the bus line. Generally, the joints between high-current busbar sections have precisely machined matching surfaces, and these matching surfaces are silver-plated to reduce contact resistance. When using ultra-high voltages (over 300 kV) on the outdoor bus, corona discharge around the connection can become a source of radio frequency interference and power loss, so special connection accessories designed for these voltages are used.

4. Various shapes allow a larger span between the bus bar fabrication equipment supports in outdoor electrical switch stations.

The bus bar fabrication equipment can be made into various shapes, such as flat bars, solid bars or rods, and solid or hollow tubes usually made of copper, brass or aluminum. Some of these shapes dissipate heat more efficiently because of their high surface area to cross-sectional area ratio. The skin effect makes the thickness of the 50-60 Hz AC bus manufacturing equipment less than about 8 mm, so hollow or flat shapes are common in higher current applications. The hollow part also has a higher stiffness than a solid rod of equivalent current-carrying capacity, which allows a larger span between the bus bar fabrication equipment supports in the outdoor electrical switch station.
