The invention discloses a test device and test method for a cable resistant to high temperature and high pressure steam and belongs to the technical field of machining and manufacturing antennas and cables. The test device for the cable resistant to the high temperature and high pressure steam comprises a test sample circuit formed by the fact that a cable test sample penetrates through a sealed pressure container, a current transformer and a feed-through transformer. A thermometer and a pressure meter are arranged on the sealed pressure container, cable nominal voltage is injected in the end of the cable test sample, the test sample circuit is connected with a cable rated current unit, and a temperature monitoring unit is arranged on the test sample circuit in a matched mode. By means of the test device and the test method for the cable resistant to the high temperature and high pressure steam, detection and inspection are mainly carried out on various electrical performance and mechanical performance under the condition that the cable resistant to the high temperature and high pressure steam is arranged in the 210 DEG C and 2MPa steam for two hours, it can be proved that leakage does not happen to the cable resistant to the high temperature and high pressure steam in the 210 DEG C and 2MPa steam for two hours, and the cable still has the electrical performance and the chemical performance meeting the use requirement.
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...
