What is a high-voltage bus duct? I have heard a lot about bus ducts, but I am not familiar with high-voltage bus ducts. High voltage bus duct, also known as high voltage common box bus duct. Generally used in large substations, power supply systems, and self owned power plants of large enterprises. It replaces the traditional bare wiring method, and not only has the characteristics of safety, aesthetics, and reliability, but also greatly reduces the number of power outages and maintenance due to the enclosed shell of the high-voltage bus duct. When transmitting large currents, it can eliminate faults caused by unbalanced current distribution caused by the use of double or triple high-voltage cables. Ensure the reliability of power supply. It can be widely used in transmission systems below 10KV and up to 2000A.

Purpose:

The purpose of high-voltage bus duct is to provide electrical connections between transformers and high-voltage distribution panels, power supply systems in large factories and mines, large substations, and self owned power plants of large enterprises, as well as electrical connections between generators and step-up transformers. It can be widely used in transmission systems below 10KV and up to 2000A.

Working Principle:

The high-voltage bus duct adopts a high-strength and high-performance DMC insulation support block clamping structure, which has good load performance and dynamic thermal stability; Strong overload capacity and low temperature rise. To strengthen the insulation type fully enclosed high-voltage bus duct, with a protection level of IP40, the conductor is fully encapsulated with high-voltage heat shrinkable tubing, and can be used in areas with an altitude of up to 2000m.

The high-voltage bus duct replaces the traditional bare wiring method and adopts enclosed packaging, which can greatly reduce the number of power outages and maintenance. When transporting large currents, it can eliminate faults caused by unbalanced current distribution caused by the use of double or triple high-voltage cables. Ensure the reliability of power supply.

   In addition to the above, the high-voltage common box bus duct also has the following characteristics:

1. The high-voltage common box busbar adopts weak magnetic metal material as the shell, which can effectively reduce the structural heating caused by eddy currents or circulating currents, lower the temperature of the common box busbar shell, reduce electrical energy loss, and reduce short-circuit electromotive force.

2. The high-voltage common box busbar has an excellent structure, and installation and maintenance holes can be freely set at the upper or lower part of the common box busbar. For high current indoor products, ventilation louvers can be set on both sides and the lower part of the shell to enhance heat dissipation and reduce busbar temperature rise.

3. In order to avoid the resonance frequency range of the busbar and reduce the electric force acting on the busbar, the type, specification, and strength level of insulators are selected, and the distance between insulators is reasonably set.

4. To prevent condensation caused by air convection inside and outside the enclosure, a partition device can be installed at the wall penetration point to completely isolate the outdoor and indoor shared busbar.

5. Temperature measuring devices for monitoring conductors, joints, or enclosures can be installed at the joints of high-voltage common box busbars or other locations that are prone to overheating, to facilitate the detection and maintenance work of personnel.
