Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vacuum arc extinguishing chamber, and particularly relates to a vacuum arc extinguishing chamber shielding cylinder anti-deviation tool. BACKGROUND

[0002] The shielding cylinder and the porcelain shell are core components of the vacuum arc extinguishing chamber and play a crucial role. In the production process of the vacuum arc extinguishing chamber, the fixing mode of the shielding cylinder has undergone a change from spinning to welding, and this industry trend makes the welded shielding cylinder the most common and key fixing method. In the production process of the welded shielding cylinder arc extinguishing chamber, the existing assembly mode is as follows: the operator first accurately places the solder sheet on the metallized step inside the porcelain shell, and then places the shielding cylinder on the same metallized step. Subsequently, the entire assembly is sent into a vacuum brazing furnace, and through a high-temperature welding process, the metallized steps of the shielding cylinder and the porcelain shell are firmly connected.

[0003] However, this manual assembly method has a significant defect: due to human factors in the operation process, the shielding cylinder may not be completely aligned or may be deviated, and such deviation is often difficult to visually detect in subsequent visual inspection. The slight deviation of the shielding cylinder cannot be ignored, as it directly affects the electric field distribution inside the arc extinguishing chamber, thereby weakening the insulation performance. In subsequent electrical aging tests, the decline in insulation performance may cause a breakdown phenomenon inside the arc extinguishing chamber, which not only affects the performance of the product but also directly leads to product scrap in severe cases, increasing production costs and waste. SUMMARY

[0004] The utility model aims at overcoming the above problems, and provides a vacuum arc extinguishing chamber shielding cylinder anti-deviation tool, which can position the porcelain shell and the shielding cylinder during the assembly of the shielding cylinder, avoid the deviation of the shielding cylinder, and improve the quality of the vacuum arc extinguishing chamber product.
