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...
