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

Abstract

The invention relates to an explosive detonation property testing system under a pulse high voltage and a tested explosive loading part. The microseond-stage pulse high voltage of the required pulse width is generated by a capacitive energy storage and charging unit and a pulse width control unit, and applied to the tested explosive loading part; then, a tested explosive is ignited by an ignition and explosion propagation unit in time sequence; and finally the high voltage resistance, the time sequence ignition stability, the detonation output property and the like of the tested explosive are measured by utilizing a detonating velocity and detonation voltage testing unit and a high voltage resistant testing unit under the microseond-stage pulse high voltage condition of the required pulse width. The explosive detonation property testing system and the tested explosive loading part are applicable to the explosive detonation property testing under the pulse high voltage, and have the characteristics of low cost, simple structure, adjustable pulse width and the like.

Description

technical field [0001] The invention belongs to the field of pulse power technology and explosive detonation performance testing, in particular to an explosive detonation performance testing system under pulse high voltage and a charged part of the explosive to be tested, which is a device capable of generating microsecond pulse high voltage. Background technique [0002] In the field of pulse power technology, especially in the field of explosive pulse power technology, it is often necessary to use high-energy explosives and put them under the action of pulse high voltage. The detonation process and parameters such as detonation velocity and detonation pressure are not affected by the pulsed high voltage. Typical applications are explosive magnetic compression generators, high-voltage explosive switches, etc. [0003] Magnetic Explosion Compression Generator (MFCG) is a pulse current amplifying device designed according to the magnetic field freezing effect. It uses the c...
