Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] like Figures 1-8 As shown, one embodiment of this utility model discloses an AC withstand voltage test device for a surge arrester, including an AC discharge detection system 100 and a sliding block assembly 200.

The base plate 133 has the upper baffle 132 at one end and the lower baffle 134 at the other end. The left slide rail 138 and the right slide rail 139 are located on the side of the base plate 133 away from the cabinet. One side of the lifting slider 140 is slidably connected to the left slide rail 138, and the other side is slidably connected to the right slide rail 139. One end of the lead screw 136 passes through the bearing seat 135 and is connected to the coupling 137, while the other end of the lead screw 136 passes through the lifting slider 140 and is connected to the lower baffle 134. The coupling 137 passes through the upper baffle 132 and is connected to the lifting motor 131.

[0031] It should be noted that the discharge insulating rod 121 is made of polymer insulating material to completely separate it from the high-voltage electric field, driving the metal contact disc to move and make contact. The vertical movement is controlled by a computer and can meet the height requirements of all metal oxide surge arresters of 35kV and below currently on the market. The upper metal contact post of the surge arrester 300 makes contact with the discharge disc to conduct the high-voltage electric field.

[0032] In one embodiment, the discharge disk is a discharge disk 123; the discharge disk 123 is used to detect AC discharge.

[0033] Furthermore, one end of the lifting rod mounting plate 110 is connected to the lifting slider 140, and the other end is connected to the discharge insulating rod 121.

[0035] It should be noted that the sleeve 220 is compatible with all cylindrical outer diameter sizes of 35kV and below metal oxide surge arresters 300 currently on the market; the surge arrester insulating base 210 provides good support and conductive insulation performance for the entire device structure, ensuring good contact conductivity at the lower part of the metal oxide surge arrester 300, and can be expanded to install various metal products on the market for discharge contact.

[0036] Furthermore, the four pulleys 240 are arranged in pairs, with each pair positioned on one side of the chain track.
