The waterproof level of dense bus duct determines the usage environment

Release time:: 2022-05-23 Click count: 975

  Dense bus ducts are generally used indoors,and the humidity in the air does not affect the operation of the bus ducts.However,if water enters the bus ducts during use,it will inevitably cause insulation reduction,and long-term operation will cause short circuits and burn out the bus ducts.Therefore,necessary protective measures should be taken for installation methods that may cause water ingress into the bus duct.For example,when a dense bus duct passes through a floor,if water accumulates due to production or roof leakage,it will leak down the bus duct passing through the floor,causing water ingress into the dense bus duct and reducing its insulation.

  The installation of dense busbar trunking can be directly connected from the transformer to the low-voltage distribution cabinet,or directly connected from the low-voltage cabinet to the distribution system as a distribution main line.Dense busbar trunking has the advantages of small volume,compact structure,high transmission current,and easy maintenance,playing a role in power transmission for power supply and distribution equipment in industrial and mining,enterprises,and high-rise buildings.If there is water ingress in a dense busbar duct,it depends on the protection level of the busbar duct.If the protection level is high,a small amount of water may not cause much damage to it.If the protection level is low,the water must be cleaned before use,otherwise a short circuit may occur.

  What to do and solve if water enters the dense bus duct during use?Regular maintenance and inspection should be carried out during the use of bus ducts to ensure safe transmission of current.In the process of using dense bus ducts,it is common to encounter equipment water ingress,which can affect the use of bus ducts.Different methods of water ingress solutions are also different.Compared with traditional cables,dense bus ducts fully demonstrate their superiority in high current transmission.The contact resistance and temperature rise at the connection points at both ends of the bus duct and the junction of the distribution port are measured,and high-quality insulation materials are used in the bus duct.

  Dense busbar trunking is supported by a strong metal shell,which can withstand stability under large electric force impacts.Due to strong mechanical stress,it can be used to adopt busbars with a large aspect ratio and arranged vertically.The dense bus duct has a high current carrying capacity,resulting in an increase in current density and a significant reduction in product cost.The structure of the busbar connection and socket of the dense bus duct is more complex,the manufacturing difficulty is increased,and the production process cost is high.The dense bus duct adopts a bus with a large width to thickness ratio,which increases the heat dissipation surface of the bus itself and directly transfers it to the shell through insulation material,utilizing a strong convective heat dissipation method.
