Description

technical field [0001] The invention relates to the field of insulating dielectric space charge measurement, in particular to an self-adaptive adjustment electrode clamp device. Background technique [0002] Space charge measurement technology is the basis for studying space charge characteristics of insulating dielectrics. At present, the space charge non-destructive measurement technology is based on the disturbance method, and the most representative methods include electroacoustic pulse method (PEA), pressure wave method (PWP) and thermal pulse method (TP). Although these three space charge measurement techniques have different measurement principles, they all basically require a pair of electrodes for sandwich support to fix the measured flat plate or thin film dielectric material. For the electroacoustic pulse method and the pressure wave method, when installing the electrode fixture, the two contact surfaces of the electrode fixture should be parallel and can be clos...

AI Technical Summary

Problems solved by technology

In practical applications, due to the existence of various factors, this electrode fixture may produce the following situations that cause the electrode contact surface to be non-parallel: 1. The contact surface of the processed electrode fixture device is not flat; 2. Install the electrode When clamping, the contact planes of the two electrodes are not completely parallel; 3. The inclination angle between the surface and the axial direction of the two contact electrodes of the electrode fixture due to wear or regrinding caused by long-term use

In the case that the electrodes are not parallel, the originally designed planar contact becomes a line contact or a point contact, resulting in additional inductance and capacitance value reduction, resulting in signal distortion. For thin film samples with a thickness of several microns, this line or point contact may also cause Sample damage, not conducive to the experiment
