Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1 to Figure 6 As shown, the present invention provides a high-voltage shielding structure for the power supply system of the electromagnetic separator, which is installed in the power supply cabinet of the electromagnetic separator, and is used to shield the high potential part of the power supply system of the electromagnetic separator. The power supply system includes several switching power supply (such as Figure 6 As shown, there are four in this embodiment), the low potential part of the switching power supply includes the mains input end, and the high potential part includes the output end. Among them, the high-potential part and the low-potential part of the switching power supply are isolated by high-voltage primary and secondary windings of a high-frequency transformer, and the (4) high-potential parts of the switching ...

Abstract

The invention belongs to the technical field of isotope production, and in particular relates to a high-voltage shielding structure for a power system of an electromagnetic separator. The high-voltage shielding structure for the power system of the electromagnetic separator is arranged in a power supply cabinet and used for shielding high potential parts of the power system of the electromagnetic separator. The power system comprises a plurality of switching power supplies, low potential parts of the switching power supplies comprise input ends of commercial power, and the high potential parts of the switching power supplies comprise output ends of the commercial power, wherein the high potential parts and the low potential parts of the switching power supplies are isolated, and the high potential parts of a plurality of the switching power supplies are integrally arranged in a zero-potential equipotential body protective cover to be integrally isolated; signal transmission between the high potential parts and the low potential parts is realized by using a way of insulation connection. By adopting the high-voltage shielding structure provided by the invention, the required shielding space of the power system of the electromagnetic separator can be reduced, and the size of the power supply cabinet is decreased.

Description

technical field [0001] The invention belongs to the technical field of isotope production, and in particular relates to a high-voltage shielding structure used in an electromagnetic separator power supply system. Background technique [0002] Electromagnetic separator is the key equipment for isotope production, and the separated isotopes play an important role in aerospace and other fields. The power supply system of the electromagnetic separator mainly includes several switching power supplies. The output end of each power supply is at a potential of 35kV, the power input adopts the mains, and the power supply cabinet is required to be grounded and shielded from high voltage. If the existing technology is adopted, the high-voltage end of each power supply needs to be shielded with high voltage, and the volume of the power supply will be greatly increased, resulting in an excessively large overall volume of the power supply cabinet.
