When the housing 1 is subjected to external impact vibration, the current transformer 20 and the voltage transformer 21 are driven to move downward by sliding between the outer side of the movable plate 2 and the inside of the slide rail 25, and at the same time drive the two first axis supports 3 to move downward, and the two first axis supports 3 drive the first push plate 4 to push the sliding block 7 to move, and the insertion rod 6 is inserted and fixed inside the two first push plates 4 and the second push plates 5, so that the two first push plates 4 and the second push plates 5 both push the sliding block 7 to move inside the sliding rod 9, and the two sliding blocks 7 squeeze the buffer rubber column 8 inside the sliding rod 9. , which can effectively buffer the impact force of the movable plate 2 descending, and at the same time, multiple hydraulic rods 12 can slow down the vibration of the movable plate 2 descending. When the current transformer 20 and the voltage transformer 21 descend, the fourth axis support 22 drives the telescopic rod 17 to move inside the connecting rod 15 and squeeze the spring 16, and moves inside the third axis support 13 through the connecting block 14, which can effectively fix the current transformer 20 and the voltage transformer 21 to prevent the current transformer 20 and the voltage transformer 21 from shaking and falling off. When the operating temperature inside the shell 1 is too high, the two heat dissipation ports 19 of the support base 18 can effectively dissipate the surface temperature of the current transformer 20, and use two cooling fans 24 to convect the air inside the shell 1 with the external air, so as to quickly reduce the temperature inside the shell 1, which is conducive to ensuring the normal operation of the equipment inside the shell 1.
