Abstract

The invention provides a high-voltage power source fault excitation monitoring device. The monitoring device comprises the following parts: a high-voltage power source module, key nodes of which are divided into high-voltage nodes and low-voltage nodes; a random vibration test bench, which stimulates possible fault modes of the high-voltage power source module under the vibration stress; a low-voltage node switching and regulating module, which regulates voltage signals of the low-voltage nodes to be within an allowable voltage-measuring range; a low-voltage node data acquisition module, which acquires and measures low-voltage node signals that have been processed by the low-voltage node switching and regulating module; a high-voltage node switching and voltage dividing module, which enables voltage signals of the high-voltage nodes to be within the allowable voltage-measuring range through voltage dividing; a high-voltage node data acquisition module, which acquires and measures high-voltage node signals that have undergone voltage reduction by the high-voltage node switching and voltage dividing module; and a host computer system, which receives the low-voltage node signals and the high-voltage node signals, and emits control commands to control and switch corresponding node voltage signals.

Description

technical field [0001] The invention relates to the technical field of power supply monitoring, in particular to a high-voltage power supply failure excitation monitoring device and a testing method thereof. Background technique [0002] During the operation of the spacecraft, the reliable operation of the high-voltage power supply for aerospace is an important guarantee for the normal operation of the spacecraft. However, the space environment is extremely harsh and complex. In addition to the harsh launch environment, the high-voltage power supply for aerospace must withstand the comprehensive effects of space environmental stresses such as electricity, vibration, and high-temperature shock for a long time during the lift-off process and normal operation in orbit. This will cause the power supply to fail, causing major losses. [0003] Therefore, how to efficiently stimulate possible failure modes of the high-voltage power supply and accurately monitor and diagnose the fa...
