This utility model discloses an aluminum shell structure for an electrolytic capacitor, including a capacitor core package. A shell is provided at the outer end of the core package, and a support strip is provided inside the shell. Multiple sets of support strips are arranged around the shell. A cover is provided on top of the shell, and the cover cooperates with the shell. A pressure-relief column is provided inside the cover. A protective strip is provided inside the support strip, and a protective pad is provided inside the pressure-relief column. A partition cavity is opened inside the shell, and a vent hole is opened inside the shell. A pressure relief pipe is provided at the outer end of the shell, and a movable piston is provided inside the pressure relief pipe. A pressure-applying spring is provided between the movable piston and the wall of the pressure relief pipe. A pressure relief hole is opened at one end of the pressure relief pipe. This aluminum shell structure provides better shock resistance, suppresses explosions, stabilizes rise, and improves protection capabilities.

This utility model discloses a high-voltage testing device for surge arresters. The device includes a testing instrument, an adsorption conductive module, and an insulating rod. The adsorption conductive module is detachably mounted on the top of the insulating rod, and the end of the monitoring harness furthest from the testing instrument is detachably connected to the adsorption conductive module. In this embodiment, the adsorption conductive module can be moved to the device under test and adsorbed via the insulating rod, enabling remote operation, ensuring operator safety, eliminating the need for an aerial work platform, saving costs and time, and improving efficiency. The detachable nature of the adsorption conductive module and the insulating rod facilitates storage and transport. The detachable nature of the monitoring harness and the adsorption conductive module facilitates harness replacement and maintenance. The overall structure can stably establish an electrical connection between the adsorption conductive module and the device under test, ensuring smooth testing.
