EDM is a kind of mold processing equipment, which is mainly suitable for testing equipment of various cables and sparks below 25mm. This equipment adopts high-voltage form, and the design is sufficiently advanced, compact and stable, but its output is stable, and the sensitivity is high enough. It is more convenient to install and use, so under what circumstances is the spark machine prone to failure?
In order to facilitate the installation and use, the DC spark machine has three structural forms: the integrated structure is compact, the sensor head, and the display controller support component as a whole, has the characteristics of compact structure and easy installation. Among them, the distributed control type is mainly used. Extrusion line, high frequency of the foam core, coaxial signal line, twisted pair line detection and other places. Split structure, where the bracket detection head is in the production line, and the display controller uses an industry standard 19-inch rack of the tray/dual desktop type, or directly to the standard configuration control cabinet to centrally control the production test line, or it can be placed on the table , But the detection head needs to be connected to the display with a dedicated cable.
Because during processing and production, the materials close to the wire products on the production line will gradually heat up. If we put the grounding cable in the electrode of high-frequency voltage for a while, the contact surface will heat up obviously, and this heat can help break down the wire. Where the insulation is thin, otherwise the wire will pass through the research electrode without being detected. The result analysis will cause the subsequent spark test and high voltage insulation performance test data to be invalid.
