Title:
COMPOSITE PROBE FOR MEASURING SPACE CHARGE DISTRIBUTION OF POLYMER, AND MEASUREMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/135510
Kind Code:
A1
Abstract:
A composite probe for measuring space charge distribution of a polymer, and a measurement method therefor. The composite probe comprises a housing, and a signal acquisition aluminium block (1), a quartz glass block (4), a piezoelectric ceramic piece (6), a voltage pulse transmission unit and a signal extraction unit which are fixed by the housing; a conductive material is adhered to the outer surface of the quartz glass block (4), the conductive material is in contact with the housing, the piezoelectric ceramic piece (6) has a positive electrode connected to the voltage pulse transmission unit and a negative electrode connected to the conductive material on the outer surface of the quartz glass block (4), and the signal acquisition aluminum block (1) is connected to the quartz glass block (4) and the signal extraction unit, respectively. The composite probe extracts a signal from a low-voltage end, and has the advantages of being safe and reliable, having high measurement accuracy, being small in design, convenient to carry, simple to operate, and easy to install, etc.
