Problems solved by technology

[0005] At present, there is no publicly published method and device for testing the detonation performance of explosives under pulsed high voltage, and the commonly used high voltage performance test is mainly completed by DC withstand voltage equipment such as voltage withstand instruments, but due to the high voltage pulse generated by related equipment The width is difficult to adjust accurately, and it is not easy to match with the test method of explosive detonation performance. Therefore, it is difficult to apply it to the test of explosive pulse power technology, and the accuracy is not high. It cannot meet the requirements of explosive detonation performance under pulse high voltage conditions. test requirements
