The invention discloses a submarine cable water-penetrating test system comprising: a temperature-measuring container equipped with a first stop valve, a pressurizing container equipped with a second stop valve, a pressurizing cylinder being communicated with the pressurizing container through a first electromagnetic valve, a loading unit which drives the pressurizing cylinder, and a water inlet pump of which a water outlet is communicated with the pressurizing container and a water inlet is communicated with a water source. A first one-way valve is disposed on a water outlet of the water inlet pump. The water source is communicated with the pressurizing cylinder through a second one-way valve. The pressurizing container is communicated with the temperature-measuring container through a second electromagnetic valve. In the invention, water fillings into the temperature-measuring container and the pressurizing container and pressurization in the pressurizing container are achieved through cooperation between the electromagnetic valves and the one-way valves, so that operations in conductor water-penetrating test and water-penetrating test under a metal sheath can be carried conveniently. The test system is simple in structure, is convenient to use and is suitable for detection of submarine cables.
Description
technical field [0001] The invention relates to a submarine cable test system, in particular to a submarine cable water penetration test system. Background technique [0002] At present, with the vigorous development of the global power and communication industries, the demand for submarine cables has increased dramatically, and the importance of submarine cable inspection has become increasingly prominent. Submarine cable inspection needs to detect various indicators of the submarine cable, one of which is the water permeability inspection of the submarine cable. The water permeability test of the submarine cable needs to carry out the water permeability test of the conductor and the water permeability test under the metal sheath. Among them, the conductor water penetration test is to simulate the cable fault in the deepest section of the cable, provide the conductor with the water or seawater pressure environment specified by the conductor product, and test the longitudin...
