The invention provides an insulation stack capable of reducing the electric field intensity of three combination points of an anode and a preparation method of the insulation stack, which are used for solving the technical problem that flashover or breakdown of the insulation stack is easy to occur because the electric field intensity of the three combination points of the anode of the existing integrated high-voltage vacuum insulation stack is too large. An annular first shielding structure is coaxially and circumferentially arranged on the inner side of a metal grading ring in the insulating stack; the first shielding structure comprises a first annular protrusion higher than the upper end face of the metal grading ring and a second annular protrusion arranged on the lower end face of the first annular protrusion. And an included angle theta is formed between the bottom surface, extending out of the side wall of the second annular bulge, of the first annular bulge and the side wall, connected ...

Принадлежит:

The invention discloses a PE film wrinkle detection system, relates to the technical field of film detection, and solves the technical problems that a film wrinkle region is not analyzed, and the reason of the wrinkle is judged according to an analysis result, subsequently, according to the specific region of the wrinkle, the wrinkle is reanalyzed, whether corresponding film bubbles appear or not is analyzed firstly, and if yes, the film bubbles exist, and if not, the film bubbles exist. If the thickness is not uniform, the melt temperature is not uniform, if the thickness is not uniform, the included angle of a herringbone plate is too large, and if wrinkles are many, the tension of a wind-up roller is too large, different judgment reasons are obtained through different analysis and processing results, and the obtained judgment reasons are displayed for external personnel to check and take response measures in time. Therefore, the use effect of the whole system is improved, and corresponding ...
