According to the test requirements, the intelligent cable water tightness test device can evaluate the water tightness of the cable under different water pressure conditions. Its working principle is: when the cable is immersed in a certain water pressure for a period of time, its insulation resistance value will change. Through the precise monitoring and analysis of the insulation resistance change trend of the cable, the electrical isolation performance of the cable in a wet or underwater environment can be accurately judged, that is, whether the waterproof performance of the cable meets the standard can be judged.

[0022] The cylinder body 10 may be a cylinder, and may be made of a steel plate of a certain thickness, and is used to hold water and place the cable sample 200.

The cable sample 200 is sealed and connected to the cylinder body 10, and after the cylinder body 10 is filled with water, the pressurizing device 20 is used to make the water pressure in the cylinder body 10 reach the test requirements.

[0026] The controller 40 is electrically connected to the cylinder body 10 and the pressurizing device 20. The controller 40 is provided with an electronic control panel for setting and displaying the test operation parameters. For example, the water pressure of the test can be set through the electronic control panel, and the real-time water pressure and the test operation time can be displayed.

The controller 40 can also be equipped with a power indicator light and a test completion indicator light to facilitate the acquisition of whether the equipment is running and whether the test is completed.

[0027] The insulation resistance tester 50 is connected to the cable sample 200 that is exposed from the sealing port 11 at one end of the cylinder body 10 , and the insulation resistance of the cable sample 200 is measured when it is immersed in a certain water pressure for a certain period of time, so as to determine the water tightness of the cable sample 200 .

[0028] The data storage device 60 is connected to the insulation resistance tester 50 and is used to record the insulation resistance value of the cable sample 200 measured by the insulation resistance tester 50 in real time to form test data, and the watertight performance of the cable sample 200 can be analyzed according to the test data. The data storage device 60 can be a computer.
