This invention discloses a waterproof testing device for
electrical control cabinets. The invention relates to the field of control cabinet testing technology and includes a base; a water tank filled with water is fixed to the left side of the top surface of the base; a frame with a concave structure is fixed to the top surface of the base, and a first
hydraulic cylinder is fixed to the top surface of the inner wall of the frame. A base block with a rectangular
block structure is fixed to the extended end of the first
hydraulic cylinder, and two spring rods are fixed to the bottom surface of the base block. Multiple testing methods are combined to ensure comprehensive testing: a first testing component performs basic sealing tests by observing air bubbles after immersing the control cabinet in the water tank; a second testing component increases the pressure inside the water tank by connecting an air inlet
pipe to an
air pump, allowing for more in-depth leakage testing. The two testing methods work together to test the sealing of the control cabinet under different pressure environments, ensuring accurate and reliable test results.
