Description

technical field [0001] The invention relates to a high-frequency and high-voltage power supply, in particular to a high-frequency and high-voltage power supply for liquid leakage detection of a bottle mouth or a bottle body of a liquid container. Background technique [0002] At present, in the production industries such as medicine and beverages, plastic containers are often used to hold certain special liquids. Because the sealing performance of the container directly affects the quality of the liquid product inside the container, and then affects the health and life safety of consumers who use this type of liquid product. Therefore, on the production line of producing this type of plastic liquid, it is very important to carry out on-line detection of the sealing performance of the wall of this type of liquid container. [0003] There are some special methods for liquid container leakage detection. Chinese patent 03157083, Chinese patent 01142523 and Chinese patent 20041...

AI Technical Summary

Problems solved by technology

The problems existing in the methods of liquid leakage detection of these liquid containers are: the one, it is difficult to carry out comprehensive sealing performance detection to the wall of the container of large surface area at the same time, the 2nd, it is difficult to detect that the wall of the sealed container exists as little as micron. tiny pores and tiny defects

In the production line using this method to detect liquid containers, due to the different structures and sizes of the liquid containers to be detected, the differences in the conductivity of the liquid contained in the containers, and the differences in the structure and discharge gap of the discharge electrodes used, it is possible that The equivalent circuit parameters resulting in liquid containers in different operating states may be different
