Abstract

The invention relates to an ignition device with controllable energy, pulse width and frequency. The ignition device comprises an igniter and a control circuit thereof, wherein the igniter comprises wires, electrodes, an electrode fixing metal shell, a flange metal shell, a sealing ring and single-hole ceramic tubes, and the control circuit comprises a low-voltage unit, a transformer unit, a current-limiting resistor, a voltage measuring unit and a current measuring unit. The low-voltage unit comprises a direct-current power supply, a power switch and a high-speed switch, the power switch, thedirect-current power supply, the high-speed switch and the input end of the transformer unit form a series loop, the output end of the transformer unit, the current-limiting resistor, the igniter andthe current measuring unit form a series loop, and the overall two ends of the igniter and the current measuring unit are connected in parallel with the voltage measuring unit. Compared with the prior art, the ignition device has the advantages of adjustable ignition energy, pulse width and frequency, wide working range and the like.

Description

technical field [0001] The invention relates to the field of ignition devices, in particular to an ignition device with controllable energy, pulse width and frequency. Background technique [0002] Existing ignition experiment studies generally directly purchase existing igniters and corresponding control modules for experiments. The parameters such as ignition energy and pulse width of such igniters are relatively single, and cannot be adjusted within a certain range according to experimental needs, so they cannot be used. It is used to analyze the influence of ignition energy and pulse width on the ignition process. Contents of the invention [0003] The purpose of the present invention is to provide a controllable energy, pulse width and frequency in order to overcome the shortcomings of the above-mentioned prior art that the parameters such as ignition energy and pulse width are relatively single, and cannot be used to analyze the influence of ignition energy and pulse...
