2600A dense bus duct

2600A dense bus ductThe outer shell of the bus duct is made of high-strength aluminum alloy profiles pressed in a streamlined shape,secretIts appearance is beautiful and reduces the weight of the bus duct. At the same time, the outer shell of the bus duct is made of aluminum alloy material, which can serve as a good grounding body and resist natural environmental corrosion. Therefore, this bus duct has obtained multiple numbers: ZL962 04064.9). The dense busbar trunking is wrapped with flame-retardant cross-linked polyethylene heat shrink tubing, which has strong insulation performance and does not emit toxic gases when exposed to fire.

The internal conductors are insulated using a new type of integral coating process, stacked together to form a compact structure, without creating a "chimney effect" combustion pathway. The molded aluminum alloy enclosed shell has high strength, excellent corrosion resistance, heat dissipation, and can be used as a grounding wire to ensure sufficient safety, providing a reliable grounding path for grounding faults and the shortest path for ground wire short circuits. When a high-capacity grounding fault occurs, it can effectively ground and protect the entire system. This structure can effectively balance the impedance of each phase, thereby greatly reducing the voltage loss of the bus duct system. The environmental performance meets the requirements of the EU ROHS directive, and the main materials will not produce toxic or harmful gases in case of fire, ensuring safety and environmental protection.

Bus ducts are used for power transmission systems in high-rise and super high-rise buildings. They have a large capacity and are easy to branch, with a current of up to 5000A. In addition, bus ducts can reserve sockets at any position, making branching extremely convenient. Therefore, bus ducts have been rapidly promoted and applied in construction projects.

Bus duct has the advantages of small volume, compact structure, reliable operation, high transmission current, easy tap feeding, convenient maintenance, low energy consumption, good dynamic and thermal stability, and long service life.

Bus ducts are suitable for various power transmission main lines, including high-voltage bus ducts and low-voltage bus ducts. Power transmission from transformers to distribution cabinets in high-rise buildings, industrial plants, airports, docks, subways, and comprehensive construction projects, as well as from distribution cabinets to workshops and floors.

In general, a DC power supply system consists of an AC screen, a rectifier screen, and a DC screen. After adopting a closed bus duct, adjustments need to be made to the conventional DC power supply system:

1. Install one or two high-capacity DC split screens in the exchange room, and set up large circuit outputs inside the DC split screens;

2. Install a bus tie screen in the DC power supply system of the power room, which functions as a bus output and does not have an output circuit inside the cabinet;

3. Connect the DC split screen to the bus tie screen using a closed bus duct;

4. The power supply of the DC column head cabinet in the exchange room is all from the DC distribution screen in this room.

Notes:

(1) After the maintenance of the busbar trunking, before power transmission, it should be checked that all the busbar isolation switches that have been repaired on the busbar are in the disconnected position to prevent other equipment from mistakenly charging.

(2) When the busbar maintenance work is completed and the double busbar connection is restored to the fixed connection method, the dense busbar trunking should use busbar charging protection to charge the other busbar through the busbar coupling switch. After the high and low voltage dense busbar trunking is well charged, the charging protection connection piece should be removed, and then the busbar should be reversed to restore the fixed connection method.

Bus duct is made of high conductivity copper and aluminum materials for transmitting electrical energy. It is a product that collects and distributes electrical energy.

Live parts - Conductors or conductive components used to conduct electricity in normal use, including neutral conductors but excluding neutral protective conductors. Bare conductive component - a touchable conductive component of electrical equipment that is typically not charged, but may become charged in the event of a malfunction. Protective conductor - a conductor that is electrically connected to the following components to prevent the risk of electric shock. Special reminder: Cables are represented by section, and bus ducts are represented by rated working current (generally referred to as 400A bus ducts). Domestic products with the same 400A have a section of 240mm, while some are only 180mm. The difference is too large, so there are some products priced at 1.4 yuan/ampere x meter, 2.0 yuan/ampere x meter, and even higher. It is recommended to request the manufacturer to provide an explanation of the insulation method and label the bus specifications to avoid being deceived.. Composed of copper busbar, shell, insulation material, etc. The copper busbar has an insulation layer on its surface and is clamped inside the shell after being fastened, which is called a dense insulation type bus duct. For the three-phase five wire busbar trunking system, the phase row specification is 100-400A, and the PE row section is the same as the phase conductor section. When it is greater than or equal to 630A, the PE row section is half of the phase conductor section. The bus duct shell is made of cold-rolled steel plate, with sufficient mechanical strength, dense bus duct function, surface acid washing, phosphating, electroplating, spraying, good anti-corrosion performance, long service life, smooth surface, beautiful color, and protection level of IP45 or above. The shell grounding is convenient, reliable, safe, and the protection circuit connectivity test is qualified.

The special feature of this dense bus duct is that it can arrange two sockets within one meter of length, such as two sided sockets, which can reach four sockets without affecting the support strength of the bus. By inserting the current branch through the plug-in box, one can avoid the trouble of cable stripping and unsafe connection. If your product or equipment is replaced, reassemble and install the busbar, and ensure that the busbar socket branch always reaches the position you need. Therefore, using busbar wiring can satisfy you for life.

When the busbar maintenance work is completed and the double busbar connection is restored to the fixed connection method, the dense busbar trunking should use busbar charging protection to charge the other busbar through the busbar coupling switch. After the high and low voltage dense busbar trunking is well charged, the charging protection connection piece should be removed, and then the busbar should be reversed to restore the fixed connection method.
