Described porcelain vase mask standardization test unit, its base is equipped with multiple leakage current tables, and the low-pressure side of reometer and shell all link together, and on base, can place multiple detection platform simultaneously.
Described external electrode and interior electrode, its shape is identical with porcelain vase mask profile.For can one-time detection the porcelain vase mask of different patterns, can have the external electrode of various shape and interior electrode with for subsequent use.
Described external electrode and interior electrode, its low 3cm of aspect ratio porcelain vase mask or lower, to reach the not internal electrode discharge of external electrode at the trial.
Described detection platform, comprise external electrode bracket and detection platform support bar, support bar adopts insulating material to make, external electrode bracket does not adopt and is fixedly connected with external electrode, so that change the external electrode of different patterns, but in order to ensure the reliability of its connection, external electrode bracket can adopt plain conductor to be connected with external electrode.
Adopt the present invention to there is following advantage:
1, on base, be fixed with multiple leakage current tables and can place multiple detection platform and can ensure once can detect multiple porcelain vase masks.
2, external electrode is identical with porcelain vase mask profile with interior electrode shape, can guarantee that external electrode reliably contacts with interior electrode; External electrode and interior electrode adopt variation can be used for detecting the porcelain vase mask of different patterns.
3, external electrode bracket does not adopt to be fixedly connected with to have facilitated from external electrode and changes external electrode to detect the porcelain vase mask of different patterns, adopts plain conductor to connect and has improved the reliability that external electrode bracket is connected with external electrode.
In sum: porcelain vase mask standardization test unit can the multiple same pattern of one-time detection or the porcelain vase mask of different patterns, have improved the efficiency that porcelain vase mask detects, and have reduced testing staff's labour intensity.
