Problems solved by technology

However, the germicidal devices or electron beam emitters respectively known from the prior art are generally heavy, rather large and inconvenient to use
In particular, they are generally not suitable for compliance with the requirements of the packaging industry
[0003] For example oil as an insulating medium for insulating the power supply unit from the housing can cause problems with food industry applications or in the medical / biological field, since the oil can leak out and damage or contaminate the material to be sterilized
In addition, the use of oil increases the weight of the components

Embodiment Construction

[0068] Figure 1a A schematic side sectional view of a first preferred embodiment of a power supply unit is shown. The power supply unit comprises a housing 20 having an outer wall 23 and an inner wall 22 . The inner wall 22 divides the housing 20 into a first chamber 24 and a second chamber 25 . Both chambers 24, 25 are filled with an insulating gas 50, in particular nitrogen. Nitrogen was pressurized. The pressure is advantageously in the range of about 2 to 3 bar, which means 1-2 bar higher than the normal pressure of 1013 mbar. Housing 20 and chambers 24 and 25 extend along axis A. As shown in FIG. At the bottom end of the housing 20 , the power supply unit includes a high voltage output connector 85 . Within the first chamber 24, a voltage multiplier 80 is provided comprising a lower voltage region 82 (eg up to 70kV-90kV) and a higher voltage region 84 (eg 80kV-150kV). The lower voltage region 82 includes discrete or integrated components that operate at a lower volt...

Abstract

A power supply unit, especially for sterilization equipment, comprising a housing (20) and an electrical system (40), wherein the electrical system (40) is arranged inside the housing (20), characterized in that the housing ( 20) Filling with an insulating gas (50), in particular nitrogen, wherein the insulating gas (50) is suitable for electrically insulating the electrical system (40).

Description

technical field [0001] The invention relates to a power supply unit, in particular for a sterilizing device, to a sterilizing device, in particular for packaging material, and to a method of electrically insulating a power supply unit, in particular for a sterilizing device. Background technique [0002] Electron beam irradiation has been seen as a promising alternative for sterilization purposes for which wet chemical processes involving hydrogen peroxide have been the traditional technology platform. Electron beam irradiation provides sufficient sterilization of eg packaging material, thereby eliminating the negative consequences of wet chemical processes eg in packaging machines. However, the germicidal devices or electron beam emitters respectively known from the prior art are generally heavy, rather large and inconvenient to handle. In particular, they are generally not suitable to comply with the requirements of the packaging industry. [0003] For example oil as an ...
