When overvoltage occurs in the power grid for some reason, it may cause the dirty and cracked bushing to break down, resulting in single-phase grounding or phase-to-phase short circuit accident. The damage of the porcelain sleeve is easy to cause the moisture inside the transformer and the porcelain sleeve, which will reduce the internal insulation of the transformer and the porcelain sleeve, and cause the porcelain sleeve to break down and the transformer winding to be damaged. In rainy and humid weather, the dirty and cracked bushing may cause creepage, and in severe cases, it may cause single-phase grounding or phase-to-phase short circuit accident.

By arranging the external telescopic rod and the internal telescopic rod, the lifting of the extrusion device can be controlled. After the extrusion device is immersed in water, the extrusion device is controlled to move up and down, so that the test piece on the circular placement plate of the extrusion device is vibrated up and down, the air in the broken porcelain sleeve is discharged faster, and the detection efficiency is improved. By the up-and-down movement of the internal telescopic rod, the sawtooth structure arranged on the strip-shaped plate fixedly connected with the external telescopic rod is engaged with gear one to control the forward and reverse rotation of the gear one, and then the gear two engaged with the gear one is controlled to rotate forward and reverse by the gear one, so that the extrusion device fixedly connected with the gear two rotates forward and reverse, thereby the test piece on the circular placement plate of the extrusion device is rotated left and right, the air in the broken porcelain sleeve is discharged faster, and the detection efficiency is improved.
