Description

Technical Field

[0001] The utility model relates to an intermediate joint assembly for a tubular busbar, belonging to the technical field of joints for tubular busbars. Background Art

[0002] The tubular busbar is one of the key equipment in the power transmission and transformation system, and plays an important role in the safe and reliable operation of the power transmission and transformation system and power equipment. It is mainly used in the conductor connection between the power transmission line and the transformer of the substation in my country's power construction projects, the jumper in the transmission line, the connecting conductor in the power equipment, and the overcurrent conductor in the large current DC ice melting device. It is a new conductor that replaces the traditional rectangular, trough, rod-shaped busbar and soft wire. It is one of the key equipment (materials) in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment.

[0003] In the prior art, for example, the Chinese patent number CN 213989239 U, “A kind of anti-dropping tubular busbar intermediate joint sleeve assembly”, comprises coaxially connected conductive A tube and B tube, a conductive ring, matched conductive semi-circular arc tube sleeves, and an open clamp; the A tube and the B tube are respectively provided with annular grooves on the inner outer walls of the joint ends; the conductive ring is cooperatively sleeved on the outer side of the annular groove; the semi-circular arc tube sleeves are in a semi-circular arc shape, and annular grooves are provided on the inner inner walls of both ends; the open clamp is provided with an axial opening seam, which is sleeved and clamped on the outer side of the semi-circular arc tube sleeve; by welding the opening seam, the open clamp clamps the two matched semi-circular arc tube sleeves, the conductive ring, the A tube, and the B tube. The beneficial effect is that the anti-detachment tubular busbar intermediate joint sleeve assembly of the utility model effectively utilizes the skin effect principle of current running on the surface, and uses an outer lining conductive semi-circular arc pipe sleeve with a larger cross-section and surface area than the conductive A and B pipes of the two intermediate joints butted against each other as the intermediate connection carrier, and the two conductive pipes and the two semi-circular arc pipe sleeves have annular grooves at corresponding positions, which are clamped with open clamps; due to the design of the material, the temperature rise at the connection of the intermediate joint is lower than the temperature rise of the two conductive pipes themselves, thereby effectively preventing the shrinkage and loosening of the A pipe and the B pipe due to thermal expansion and contraction, and enhancing the pulling force, thereby reducing the temperature rise of the conductor of the intermediate connection and eliminating the hidden danger of the joint falling off due to thermal expansion and contraction, and has the characteristics of easy installation, firm connection, good conductive effect, etc.

[0004] However, in the prior art, the existing tubular conductive busbars use internal or external connection technology when connecting the tubes. In actual applications, these two technologies are prone to causing the joints to fall off due to the contraction of the two conductive tubes due to thermal expansion and contraction. If they fall off, there are certain safety hazards. Therefore, a tubular busbar intermediate joint assembly that is not easy to fall off is designed. Utility Model Content
