A control panel can be simplified, reliability and anti-electromagnetic interference performance of the control panel can also be increased, high electromagnetic interference is overcome, reliable operation of a high-voltage pulse power supply is realized, 80kV / 70A output is realized, and an EAST device experiment is successfully participated.
Description
technical field [0001] The invention relates to the technical field of controllers, in particular to a comprehensive protection cabinet for a high-voltage pulse power supply. Background technique [0002] The 80Kv / 70A high-voltage pulse power supply is an important part of the national science project EAST neutral beam injection system. Comprehensive protection of the soul of the power supply of the chassis is the key to determine whether the power supply can operate reliably. At present, there is no similar high-power high-voltage pulse power supply in China, and the low-power pulse power supply is controlled by a microprocessor. However, the working stability of the microprocessor is low under high electromagnetic interference. Therefore, it is necessary to develop a special comprehensive protection and control cabinet for this high-voltage pulse power supply. Contents of the invention [0003] The purpose of the present invention is to provide a high-voltage pulse...
