Technical Field

[0001] The utility model relates to a detector, in particular to a detector for a wire and cable spark tester. Background Technique

[0002] A wire and cable spark tester is a device used to detect whether there are defects in the insulating layer of wire and cable. This device applies a high voltage to the cable to generate electric sparks, so as to discover and locate the defect points of the insulating layer. The spark tester loads the set voltage value onto the insulating wire periodically according to a certain rule, while the conductor part is grounded, so that a voltage difference is formed between the conductor and the insulating surface, thus the insulating layer can be detected for defects.

[0003] The stability of the tester is crucial. Before conducting the spark test, it is necessary to detect the tester, including detecting the voltage at the bead chain end of the spark machine. In the traditional detection method, the bead chain end is connected to the high-voltage end of the digital high-voltage meter of the calibration device through a high-voltage lead wire. However, the connection between the lead wire and the bead chain end is relatively complex, and rapid and convenient detection cannot be achieved.

[0004] Therefore, a detector for a wire and cable spark tester is needed to improve the above problems. Content of the Utility Model
