Hit piece initiation system and generally use discrete high-voltage capacitor, high-voltage switch gear, high-voltage connector, Slapper detonator and connection cables
Deng composition.For reliable initiation, generally require the capacity of high-voltage capacitor sufficiently large, discharge switch has sufficiently fast closure speed
Degree, and discharge loop is as short as possible to reduce the energy loss on circuit.
Due to the Exploding Foil that the load in high pressure pulse discharge circuit is impedance very little（Impedance is milliohm level）Even if introduce micro-
Small impedance loop, will also result in and energy in CDU is redistributed, so as to being caused by the pulse current waveform of Exploding Foil
Large effect.To ensure the ability of the grafting reliability of high-tension connector and carrying pulse high current, high-tension connector has
Effect patches length and is generally not less than 3mm ~ 5mm, even if the material impedance of high-tension connector is smaller, is still inevitably discharging back
Certain inductance and resistance are introduced in road, result of the test shows, even if using the high-voltage connector with 7mm conducting wires in the loop,
Monitor the peak atenuation 20% of its discharge current in load, discharge cycle extension 25%.Connecting wire is longer, is lost on circuit
Energy it is bigger.
In existing impact piece initiation system, Slapper detonator is pressed off with the high-voltage capacitor in capacitance discharge cell, height
Close（Vacuum spark gap switchs or semiconductor switch NMCT）, the device such as high-voltage connector combination is simply welded using conducting wire, mainly
Have the following disadvantages：System bulk is big, limits the application in many occasions；Discharge loop is grown, and energy loss is larger；Discharge back
The parameter such as conducting wire parasitic parameter, connector contact resistance, which exists, in road spreads, and is unfavorable for performance boost；System welding usability is not
Good, assembly manipulation link easily impacts system reliability.
Li Jie of Beijing Institute of Technology et al. has applied for a kind of patent of Microminiature high-voltage discharge device in 2013, proposes
High-voltage capacitor is made as annular, in the priming device side of middle installation Slapper detonator, end face arrangement printed circuit board
Case, relative to general impact piece initiation system, more compact structure.But the device is substantially still the combination of discrete device, only
It is the optimization done in structure, can not fundamentally solves the deficiency that generally impact piece initiation system shares.
