Abstract

An igniter squib testing device comprises a first switch (Q1), a load interface (J2), an igniter squib interface (J1) and a controller (7), wherein, one end of the first switch (Q1) is connected with one end of the igniter squib interface (J1) in series by the load interface (J2), the other end of the first switch (Q1) and the other end of the igniter squib interface (J1) are respectively used for being connected with a positive pole and a negative pole of a power supply, and the controller (7) is connected with a control end of the first switch (Q1) and is used for receiving enabling signals, controlling the first switch (Q1) to close and controlling the first switch (Q1) to be cut off by preset time. The igniter squib testing device accurately controls the conduction time of an ignitionsquib, thus providing effective and safe protection for the test process of the ignition squib.

Description

technical field [0001] The invention relates to the field of current testing, in particular to a testing device for an ignition tube. Background technique [0002] The ignition tube is an ignition device that converts electrical energy into heat energy to cause an explosion. It has a minimum ignition current value and a maximum safety current value. It is triggered by introducing a current above the minimum ignition current value into the ignition tube and generating heat after a certain period of time. Explosion, and the current below the maximum safe current value into the ignition tube will not cause an explosion. The minimum firing current value and the maximum safe current value of the ignition tube are important parameters for correctly understanding the electrical characteristics of the ignition tube, and are also the main basis for designing the ignition tube and blasting network. Correctly mastering the test method of the minimum ignition current value and the maxi...
