The discharge phenomenon of the complete set of frequency conversion series resonance test equipment is a common concept, generally referring to the phenomenon of insulation materials transitioning from an insulating state to a conductive state under the action of an electric field. This phenomenon may occur in the form of an “open” between the electrodes, that is, a short circuit in the insulation material. Completely destroyed. At this point, the voltage between the electrodes rapidly drops to very low or close to zero, which is called destructive discharge; The local area between electrodes may also experience a jump phenomenon, causing a local short circuit in the insulation material. Other insulation materials have good insulation performance, and the voltage between electrodes can still maintain a certain value, which is called a local short circuit.
Destructive discharge and partial discharge can be used for all dielectrics and their combinations. However, discharge occurs in different dielectrics, and their combination has a special name. In gas or liquid media, destructive discharge between electrodes is called spark discharge, such as destructive discharge in air gaps and oil gaps, or more accurately, spark discharge. When destructive discharge occurs in a solid medium, it is called breakdown. When breakdown occurs, traces will be left in the solid dielectric, causing the solid dielectric to lose its insulation performance.
Precautions for use
1. Resonant power supply products are mostly high-voltage testing equipment, requiring the use of high-voltage testers. Before use, carefully read the user manual and undergo repeated operation training.
2. There should be no less than 2 operators, and they should strictly follow the safety operating procedures related to high-voltage testing of the unit when using it.
3. To ensure the safety and correctness of the test, in addition to being familiar with the product manual, it is also necessary to strictly follow the relevant national standards and regulations for the test operation.
4. The connecting wires should not be connected incorrectly, especially the ground wire, otherwise it may damage the testing device.
5. When using the equipment, if the output is high voltage or ultra-high voltage, it must be reliably grounded, and attention should be paid to the safe distance during operation.
