Description

Technical Field

[0001] This invention relates to an auxiliary device for installing insulating tie rods on solid-sealed poles, and more specifically to an auxiliary connection device for insulating tie rods on solid-sealed poles and its tie rod support assembly. Background Technology

[0002] Solid-sealed terminals are formed by casting the conductive components of a vacuum interrupter into epoxy resin. For example... Figure 1 As shown, the bottom end of the vacuum interrupter is provided with the moving end 1 of the interrupter. During the process of assembling the solidified pole 1 into a circuit breaker after curing, an insulating tie rod 2 needs to be installed at the moving end 12 of the interrupter. The insulating tie rod 2 includes a casting section 5, and the two ends of the casting section 5 are respectively provided with an outer end screw 3 and an inner end screw 4. The insulating tie rod 2 is threadedly connected to the moving end 12 of the interrupter through the inner end screw 4. During installation, the solidified pole needs to be placed horizontally along its own axis and fixed. Then, the inner end screw 4 of the insulating tie rod 2 is inserted through the opening end 11 of the solidified pole and aligned with the opening of the threaded connection hole on the moving end 12 of the interrupter. Then, the sleeve is fitted onto the external hexagonal structure 6 at the outer end screw 3. The sleeve is then tightened with a torque wrench to complete the installation of the insulating tie rod 2. However, when operators apply torque to the sleeve using a torque wrench, they usually apply a downward force to the sleeve. Since the support point of the insulating rod 2 is at the connection between the inner end screw 4 and the moving end 1 of the arc-extinguishing chamber, and this support point is far away from the sleeve, the insulating rod 2 is prone to downward sway after being subjected to force. This causes the insulating rod 2 and the vacuum arc-extinguishing chamber to be unable to maintain coaxial assembly, resulting in product defects. In severe cases, it may even deform the insulating rod.

[0003] Since it is inconvenient to install supports on the screw section of the insulating tie rod, the existing technology involves setting support blocks inside the solidified pole to support the casting section of the insulating tie rod and prevent it from swaying downwards or even deforming. For example, this structure is provided in Chinese patent application CN111113295A. However, this method has two problems: first, because the internal space of the solidified pole is small and complex, it is very inconvenient to operate when the support blocks are placed inside the pole; second, different solidified poles have different sizes, and the installation height of the corresponding insulating tie rod also changes accordingly. This requires support blocks of different sizes, making support blocks specifically designed for one type of solidified pole unsuitable for other types. Summary of the Invention

[0004] The purpose of this invention is to provide a tie rod support assembly for an insulating tie rod auxiliary connection device, thereby solving the technical problems of difficult operation and poor versatility in the arrangement of support blocks in the prior art. Simultaneously, this invention also provides an insulating tie rod auxiliary connection device for a fixed-position pole, to solve the aforementioned problems.
