A high-voltage power supply lead casing for a magnetic deflection mass spectrometer for space

Abstract

The invention relates to a high-reliability leading-out mode of a high-voltage power supply lead machine case of a spatial magnetic deflection mass spectrograph. The mode comprises the steps that the machine case punching is carried out in a high-voltage lead leading-out position, an insulation lead board with a fixing clamp groove is processed, the punching is carried out for each leading-out wire on the insulation lead board according to requirements, and a high-voltage power supply cabin body is led out by a high-voltage lead through a hole formed in an insulation board. The leading-out mode has the advantages that the side wall in the leading-out position of the high-voltage lead of a high-voltage power supply is made of insulation materials, so the failure mode caused by the short circuit of the high-voltage lead on a metal casing after a high-voltage lead insulation layer is abraded or scraped by the metal casing under the cruel mechanical environment effect is radically avoided, and the reliability of the high-voltage power supply in the space application is powerfully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a high-voltage power lead casing of a magnetic deflection mass spectrometer for space. Background technique [0002] The high-voltage power supply is an important component of the magnetic deflection mass spectrometer. The high-voltage power supply provides seven outputs for the magnetic deflection mass spectrometer, including scanning high voltage, focusing pole high voltage, multiplier high voltage, filament voltage, bias pole, repeller pole, and collector pole. The voltage, bias pole, repeller pole, and collector pole are all floating on the scanning high voltage, so the above seven outputs are all high-voltage outputs, and there are 10 high-voltage leads. The high-voltage power supply of the magnetic deflection mass spectrometer used in space requires high safety, especially in mechanical environments such as high-level shocks, sinusoidal vibrations, and...
