Road connects；Filling gas 3 is filled with shell 5.After shell 5 is stretched into described one end of first connection end 1, both junctions are done close
Envelope processing；After shell 5 is stretched into described one end of second connection end 6, both do encapsulation process in junction.
Consider that electric current has Kelvin effect in wire surface, can make it that the discharge-induced explosion process of wire is unstable, therefore
Wire battle array 2 is composed in parallel using wire of the more diameters less than 0.2 millimeter, and sheet metal is connected at the both ends of wire battle array 2,
As wire battle array elementary cell.
The electric explosive switch process elapsed-time standards of wire battle array 2 is less than 1 microsecond, and N number of wire battle array 2 can be in several gsecs
Realize that multiple switching acts.Because discharge-induced explosion process is very rapid, the voltage and current experience mutation in circuit can steepness electric current electricity
Press the forward position of pulse.
Public one connects a sheet metal 4 among two adjacent wire battle arrays 2, can reduce wire battle array volume of switch and again
Amount, makes its compact-sized.The insulating gas such as nitrogen or sulfur hexafluoride is filled in shell 5, is advantageous to improve when switching off
Open-circuit impedance, further steepness pulse front edge.
The wire battle array 2 includes some wires in parallel, and some wires are using the central axis of shell 5 in
The heart, the central axis parallel to shell 5 are uniformly distributed in a ring, and the wire length in same wire battle array 2 is identical, different

Flow through wire battle array switch when, energy is accumulated rapidly in wire battle array 2 with form of thermal energy, the wire in wire battle array 2 with
Heating；The first order wire battle array heating it is most fast, while earliest by solid-state heating, fusing, liquid heating, be vaporizated into it is gaseous
Physical change process, resistivity constantly increase, and wire portion evaporation of materials and close on air gas molecular ionization composition afterwards
It together form plasma and expand rapidly, wire resistance suddenly increases, and forms Electric Explosive Wires Opening phenomenon so that circuit
Disconnect for the first time；As the energy in wire battle array continues to build up, the first order wire battle array of vaporization is still heated, metal vapour
Body ionizes, and in the presence of electric arc and metallic plasma, rear class wire battle array is still not heated to the vaporization blast stage,
Whole wire battle array switch is in low resistance state, and circuit closes for the first time, and circuit turns on again；With in the wire battle array of the second level
Energy continue to build up, second level wire battle array also pass through solid-state heating, fusing, liquid heating, vaporize and discharge-induced explosion occur
Phenomenon, second of disconnection of circuit；As the energy in wire battle array continues to build up, the second level wire battle array of vaporization continues to add
Heat, metal gas ionize, and in the presence of electric arc and metallic plasma, it is quick-fried that rear class wire battle array is still not heated to vaporization
In the fried stage, whole wire battle array switch is in low resistance state, and circuit closes for the second time；By that analogy, it is a kind of to can be achieved repeatedly to open
Connected N number of wire battle array 2 in the wire battle array switch of pass action, you can produce the action of n times complete switchgear.Filling gas 3 ensures
It is dielectrically separated between wire, improves open-circuit impedance when wire battle array switches off, further steepness pulse front edge.Connect a metal
