This utility model discloses a withstand voltage testing fixture for insulating bushings, comprising a frame, a support plate fitted to the frame, and multiple high-voltage discharge components. The support plate has multiple support holes and is made of conductive material. Each high-voltage discharge component is correspondingly arranged with respect to each support hole on the support plate. Each high-voltage discharge component includes a discharge base and at least one discharge column connected to the discharge base. Both the discharge base and the discharge column are made of conductive material. The discharge base is connected to the support plate via an insulating component and is located below the support plate. Adjacent discharge bases are movably connected via a conductive switch. Each discharge column of each high-voltage discharge component passes through a support hole corresponding to that component. This utility model can quickly perform withstand voltage tests on multiple insulating bushings and can screen out unqualified insulating bushings.

This invention discloses a method for recycling titanium alloy recycled materials based on hot isostatic pressing (HIP), belonging to the field of titanium metallurgy. The method includes the following steps: First, titanium alloy recycled materials with different oxygen contents are accurately calculated and mixed to obtain a homogeneous mixture. Second, a titanium alloy sheath of the same material as the product is manufactured using 3D printing technology. The pre-mixed powder is then filled into the sheath and compacted. Finally, after vacuuming and sealing, HIP sintering is performed to directly obtain a near-net-shape dense blank under high temperature and pressure. This method optimizes the process flow by combining the full densification capability of 3D-printed sheaths with HIP technology, eliminating the remelting, sheath removal, and numerous machining steps required in traditional recycling processes. It directly produces near-net-shape products from recycled materials, significantly reducing energy consumption, labor time, and raw material loss, achieving a high-value green recycling of titanium alloys.
