Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a waterproof bus duct with excellent sealing performance. Background Technique

[0002] As a key component in modern power systems, bus ducts are widely used in industrial facilities, commercial buildings, data centers and other scenarios, and play an important role in efficiently and safely transmitting large currents. In harsh environments such as humidity, dust or chemical corrosion, the reliability of waterproof bus ducts is particularly important, and their protection level needs to reach IP66 (without tapping unit) or IP65 (with tapping unit) to ensure long-term stable operation.

[0003] Traditional waterproof bus ducts generally adopt a fully enclosed resin casting process, using highly insulating materials such as epoxy resin to completely wrap copper or aluminum bus conductors to achieve sealing and waterproofing. However, this technology has two significant defects:

[0004] 1. Insufficient heat dissipation performance: Although resin materials have excellent insulation and sealing properties, their thermal conductivity is extremely low, resulting in the Joule heat generated during the operation of the bus being difficult to effectively conduct to the external environment; the accumulation of heat is likely to cause a sudden rise in local temperature, accelerating the aging of the insulation layer and even posing a short-circuit risk;

[0005] 2. Poor sealing reliability at the connection: The connection part of the bus duct has a complex structure, and the existing sealing designs mostly rely on flat rubber gaskets or simple snap structures. Under conditions of frequent plugging and unplugging, temperature difference changes or mechanical vibrations, tiny gaps are likely to occur at the sealing interface, and moisture is likely to seep in along the gaps, threatening the insulation performance of the internal conductors;

[0006] Therefore, it is necessary to design a waterproof bus duct with excellent sealing performance to solve the above problems. Content of the Utility Model
