Description
Technical Field
The invention relates to the field of impact sheet detonator detonators, in particular to an adjustable universal pulse current generating device of an impact sheet detonator and a control method thereof.
Background
Principle of the impact sheet detonator: under the action of the pulse high current generated by the detonation circuit, the metal bridge foil generates electric explosion, and at the moment, the plastic flying sheet positioned under the bridge foil is exploded into particles and flies along the disc accelerating holes under the particles, and the particles strike the insensitive explosive column and detonate the insensitive explosive column.
Proper functioning of the metal bridge foil requires that the current pulse generated by the firing circuit has a very steep rising edge in order to be able to deliver a sufficiently large amount of energy to the bridge foil in a short time, if insufficient energy is available in a short time, the bridge foil can only melt like a normal fuse and the detonator cannot function. So the impact sheet detonator can work normally or not, which is mainly determined by the peak value and the period of the pulse current. In the development and production stage of the impact sheet detonator, a pulse current generating device is required to send out pulse current to detonate the impact sheet detonator, and the detonation current index of the impact sheet detonator is checked.
Disadvantages: at present, the pulse current generating device commonly used has fixed parameters and does not have an adjusting function, so that only pulse current with a certain fixed parameter can be output. For the same type of impact sheet detonator, the pulse current generating device with fixed output can only check a certain working point and cannot check the working range of the impact sheet detonator. For the impact sheet detonators with different types, the output current of the same pulse current generating device is possibly not in the working range, so that the universal use requirement of the impact sheet detonator cannot be met.
