The cable and a central processing unit are combined with a withstand voltage detection and display part to form the cable alternating current withstand voltage test system; the input end of the cable is connected with the test input voltage module through the voltage regulating module, the acquisition output end of the cable is connected with the central processing module through the information acquisition device, and the output end of the central processing module is provided with a display feedback device. A multi-point acquisition mode is adopted to perform information acquisition on voltage and temperature information at different positions of a cable, the precision degree during test detection can be effectively improved, the information state of a test can be monitored in real time, high-difficulty operation during manual test can be effectively avoided, the test efficiency is effectively improved, and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of cable AC withstand voltage test, and mainly relates to an online cable AC withstand voltage test system. Background technique [0002] With the rapid progress and development of our country's society, we pay more attention to the aspect of electricity consumption, especially for the use of cables. At this stage, cables are mainly used for medium and high voltage power transmission, so we need to pay attention to them when using them. The withstand voltage test of the cable is carried out in advance, but the traditional withstand voltage test basically manually increases and adjusts the input voltage to perform the withstand voltage test of the cable, the operation process is complicated, the technical difficulty is high, and The length of the cable is long, and the traditional test method is to judge the degree and effect of the withstand voltage of the cable as a whole by energizing for a long period of time, so i...

[0002] With the rapid progress and development of our country's society, we pay more attention to the aspect of electricity consumption, especially for the use of cables. At this stage, cables are mainly used for medium and high voltage power transmission, so we need to pay attention to them when using them. The withstand voltage test of the cable is carried out in advance, but the traditional withstand voltage test basically manually increases and adjusts the input voltage to perform the withstand voltage test of the cable, the operation process is complicated, the technical difficulty is high, and The length of the cable is long, and the traditional test method is to judge the degree and effect of the withstand voltage of the cable as a whole by energizing for a long period of time, so it is often difficult to carry out effective withstand voltage test detection on each node. Often only the withstand voltage at the lowest voltage can be monitored, and it is difficult to realize the actual withstand voltage upper limit of the cable. Therefore, the upper limit of the withstand voltage of the cable is too low to a large extent, which affects the withstand voltage test to a large extent. The accuracy and true effectiveness of the traditional manual test, and the traditional manual test, the work intensity is too large, it is difficult to test and detect in batches, which greatly increases the cost of test and test
