Background technology
Along with the development of Pulse Power Techniques, pulse power system miniaturization, lightness become a new developing direction.Energy storage device is as energy storage component important in the pulse power system, and the raising of its energy storage density has significance.Adopt high-k (～180), (Eb＞50kV/mm) glass ceramics can reduce its volume as the energy-accumulating medium of energy storage device to high breakdown field strength effectively.Have high breakdown characteristics glass ceramics and shown good prospects for application, become the focus of researcher research in the Pulse Power Techniques field.Because glass ceramics has the breakdown field strength far above sintered ceramic, general puncture method of testing also is not suitable for the puncture test of glass ceramics.For common insulating medium, in order to prevent that sample punctures along face in the test process, the pulse breakdown test is carried out in liquid insulating medium (like silicone oil, transformer oil) usually.Yet; Glass ceramics is carried out find in the pulse breakdown performance test process at us; The silicone oil that adopts low-k (2～3) is as tested media, and tested media is prior to sample breakdown, and this just makes the measured value of glass ceramics pulse breakdown field intensity be lower than its actual value.
Therefore, a kind of liquid testing medium that can effectively improve glass ceramics pulse breakdown performance is provided, just becomes the technical barrier that this technical field urgent need will solve.

A kind of method of testing that improves glass ceramics pulse breakdown performance is characterized in that, this method step is following:
(1) preparation glass ceramics sample;
(2) at the gold-plated film of the glass ceramics sample two sides of step (1) gained difference, as the electrode of testing capacitor;
(3) capacitor of step (2) gained is put into tested media and measure its pulse breakdown field intensity, said tested media is glycerine (GE).
The glass ceramics samples using tradition cutting of step (1), wear down, finishing method preparation.
The glass ceramics sample thickness of step (1) preparation is 0.05～0.4mm.
The golden film thickness of step (2) glass ceramics sample two sides plating is 1～3 μ m.
Beneficial effect of the present invention is: through different-thickness glass ceramics capacitor at differing dielectric constant; Pulse breakdown performance measurement experiment in the liquid medium of different breakdown field strengths is selected and a kind ofly can effectively be improved glass ceramics pulse breakdown performance and make the liquid testing medium of the measured value of its impulse breakdown strength near its theoretical value.The impulse breakdown strength of the glass ceramics sample of different-thickness is 45～106kV/mm in the different liquid medium.Especially the glycerine of high-k (42.5) can improve the pulse breakdown performance of glass ceramics effectively, thereby makes the impulse breakdown strength of different-thickness glass ceramics sample can bring up to 70～106kV/mm, more near its theoretical value.Well satisfy the test request of high-k glass ceramics pulse breakdown performance, be suitable as very much the pulse breakdown tested media of solid high dielectric constant material.
