[0025] Preferably: the shielding mechanism includes: a hinge 13, a baffle 14, a butterfly bolt 15 and a fixing hole 16, the bottom surfaces of the first protrusion 3 and the second protrusion 11 are both connected with the hinge 13, the movable end of the hinge 13 is connected with the baffle 14, one side surface of the baffle 14 is penetrated by the butterfly bolt 15, one end of the butterfly bolt 15 extends into the fixing hole 16, and the fixing hole 16 is opened on one side surface of the first protrusion 3 and the second protrusion 11.
[0026] During specific use, the baffle 14 is rotated by the hinge 13 so that one side of the baffle 14 contacts the surface of one side of the first protrusion 3 or the second protrusion 11, and then the butterfly bolt 15 is passed through the baffle 14 and screwed into the fixing hole 16, so that the baffle 14 can be fixed to one side of the first protrusion 3 and the second protrusion 11, thereby covering the opening on one side of the first protrusion 3 and the second protrusion 11. After the butterfly bolt 15 is unscrewed, the baffle 14 can be rotated by the hinge 13, so that the opening on one side of the first protrusion 3 and the second protrusion 11 is exposed again.
[0027] Preferably, the heat dissipation port 2 is connected to the positions of the inner spaces of the first bump 3 and the second bump 11 .
[0028] During specific use, the heat dissipation port 2 is connected to the positions of the internal spaces of the first bump 3 and the second bump 11 , so that the air in the first bump 3 and the second bump 11 can enter the heat dissipation port 2 .

[0030] During specific use, the dehumidification filter element 5 can slide in the slide groove 4 so that the dehumidification filter element 5 can be plugged in and out of the first protrusion 3 .
[0031] Preferably, the insert block 7 forms a sliding connection with the dehumidification filter element 5 through the slot 6 , and the insert block 7 forms an elastic structure with the stand block 8 through the movable groove 9 and the spring 10 .
[0032] During specific use, the plug block 7 can be elastically telescopically moved on the vertical block 8 through the movable groove 9 and the spring 10. When one end of the plug block 7 is slidably inserted into the slot 6, the position of the dehumidification filter element 5 can be fixed in the slide groove 4. The plug block 7 is pulled to separate one end of the plug block 7 from the slot 6, so that the dehumidification filter element 5 can be separated from the slide groove 4, allowing the operator to replace the dehumidification filter element 5.

[0035] Working principle: when using the cable withstand voltage detection device, the dehumidification filter element 5 is slidably placed into the slide groove 4. At this time, the dehumidification filter element 5 will contact one end of the plug block 7, allowing one end of the plug block 7 to slide on the vertical block 8 and squeeze the spring 10 at the same time. When the slot 6 on the dehumidification filter element 5 moves to the position of the plug block 7, the spring 10 will push the plug block 7 to move on the vertical block 8, so that one end of the plug block 7 is inserted into the slot 6. In this way, the position of the dehumidification filter element 5 will be fixed on the first protrusion 3, allowing the dehumidification filter element 5 to absorb the moisture inside the withstand voltage tester 1 through the heat dissipation port 2 to ensure the dryness of the internal environment of the withstand voltage tester 1. When the withstand voltage tester 1 runs for a long time and the fan 12 needs to be started for heat dissipation, the fan 12 will transport the hot air inside the withstand voltage tester 1 through a heat dissipation port 2. At this time, the outside air will pass The air passing through the pressure tester 1 enters the interior of the pressure tester 1 through another heat dissipation port 2, and the other heat dissipation port 2 is provided with a dehumidification filter element 5, so the air passing through the pressure tester 1 will be filtered and dried by the dehumidification filter element 5, so that the air entering the pressure tester 1 is dry, and moisture is prevented from affecting the operation of the internal components of the pressure tester 1. Secondly, when the pressure tester 1 is idle, the baffle 14 is rotated by the hinge 13, so that one side of the baffle 14 contacts the surface of one side of the first protrusion 3 or the second protrusion 11, and then the butterfly bolt 15 is passed through the baffle 14 and screwed into the fixing hole 16, so that the baffle 14 can be fixed on one side of the first protrusion 3 and the second protrusion 11, thereby covering the opening on one side of the first protrusion 3 and the second protrusion 11, thereby preventing the dehumidification filter element 5 from being in contact with the external air all the time, reducing the contact between moisture and the dehumidification filter element 5, and thus increasing the service life of the dehumidification filter element 5.
