High-voltage isulation, high conversion efficiency, high load, high-precision, low ripple are the research directions of high voltage power supply design.
Traditional DC high-voltage power supply uses metallic cabinet, due to being provided with circuit board and capacitor, coil in cabinet
Equal electronic circuits component needs to retain quite in order to avoid metallic cabinet is interfered with circuit board and electronic component
Space and distance, the size that this just inevitably causes power case it is larger, it is difficult to miniaturization and micromation.
Summary of the invention
In view of the deficiencies in the prior art and insufficient, the purpose of the present invention is to provide one kind for digitizing high pressure
The insulation cabinet of power supply.
Technical scheme is as follows:
It is a kind of for digitizing the insulation cabinet of high voltage power supply, it is characterised in that: each wooden partition of the cabinet be composite plate
Structure, including at least the layer of silica gel and the modified plastics layer on the outside of layer of silica gel for being located inside.
Further technical solution includes that the layer of silica gel and modified plastics layer pass through hot pressing being complex as a whole composite plate
Structure.
Further technical solution includes that the modified plastics is polycarbonate and polyacrylonitrile is major ingredient, is made in auxiliary material
It is heated to mix under.
Further technical solution includes, the polycarbonate and polyacrylonitrile be according to the weight ratio 50~65:15~
30。
