The invention discloses a test device and a test method for a high-temperature and high-pressure steam-resistant cable, belonging to the technical field of processing and manufacturing of electric wires and cables. The test device for high-temperature and high-pressure steam-resistant cables of the present invention includes a test sample loop formed by passing a cable sample through a closed pressure vessel, a current transformer and a feed-through transformer. The closed pressure vessel is provided with a thermometer and a pressure gauge. The end of the cable sample is injected with a rated cable voltage, the test sample loop is connected with a cable rated current unit, and the test sample loop is equipped with a temperature monitoring unit. The present invention is mainly aimed at detecting and testing various electrical and mechanical properties of the high-temperature and high-pressure steam-resistant cable under the condition of 210°C and 2MPa water vapor for 2 hours, and can prove that the high-temperature and high-pressure steam-resistant cable can guarantee 2h in the water vapor of 210°C and 2MPa It does not leak inside, and still has electrical and mechanical properties that meet the requirements of use.
Description
technical field [0001] The invention relates to the technical field of wire and cable processing and manufacturing, in particular to a test device and a test method for a wire and cable. Background technique [0002] For high-temperature and high-pressure steam-resistant cables, under accident conditions, the cables need to be able to operate normally for a period of time in a saturated water vapor environment of 210°C and 2MPa, so as to win time for emergency rescue of equipment and ensure the safety of equipment to the greatest extent. At present, there is no special testing and testing equipment for high-temperature and high-pressure steam-resistant cables, and it is impossible to judge the performance of this type of cable, let alone prove the performance of this specific type of cable. Contents of the invention [0003] The purpose of the present invention is to provide a test device and test method for high-temperature and high-pressure steam cables for the above-men...
