At combustion chamber.It is closed and filled with gas/gas mixture by (airtightly) in the combustion chamber.
Third electrode E3 and the 4th electrode E4 so arrange that is, they are not hindered between first electrode E1 and second electrode E2
The electric arc of generation passes through, and as shown in Figure 1 to Figure 3, there are channels by third electrode E3 and the 4th electrode E4.
Now, by means of electrode so arranged, other than being capable of providing from primary ignition, also it is capable of providing controlled point
Fire.
Visible a kind of illustrative manipulation in Fig. 4.There inflatable overvoltage arrester USE according to the present invention be in
In the parallel circuit of varistor VAR1.In addition, the parallel circuit can connect with optional safety device F.With current potential N
It is additionally provided with a kind of ignition circuit between (ground connection) and the electrode E1 and E2 that connect (major loop) with current potential L, can be realized outside
Triggering.
Real triggering from before primary ignition between electrode E1 and E2 can by different spatial designs come
It realizes.
In the example of the embodiment of Fig. 1, lower sound is provided by lesser spacing A1 between electrode E3 and E4
Answer voltage.The response voltage is less than the response voltage between first electrode E1 and second electrode E2 herein, it is characterised in that spacing
It is A2+A2+A1.But about mutual between first electrode E1 and third electrode and between second electrode E2 and the 4th electrode E4
Spacing A2, it is characterised in that corresponding spacing A2, response voltage are smaller.
That is, higher voltage is needed for from primary ignition, and for the igniting between electrode E3 and E4, it is lesser
Voltage is with regard to enough.That is, spacing A2 is consistently greater than spacing A1.The external point of approximate center can be carried out in this example embodiment
Fire.
In the embodiment of Fig. 2, electrode E1 and electrode E3 formed can external trigger igniting route, and electrode E4 and E2
Formation can be from the igniting route of primary ignition.
Lower response is being provided by lesser spacing A1 between electrode E1 and E3 in the example of the embodiment of Fig. 2
Voltage.The response voltage is less than the response voltage between electrode E4 and electrode E2 herein, it is characterised in that spacing is A2.

Two logic combustion chambers." logic " combustion chamber formed herein has different response voltage.
So, compared to another " logic " combustion chamber there is " logic " combustion chamber of smaller response voltage can use
Make can external trigger combustion chamber.If lighting " logic " combustion chamber leads to ionization in physics combustion chamber, another " to patrol
Volume " combustion chamber also lights.It should be noted that response voltage (that is the electrode E1 and electrode of single " logic " combustion chamber
Response voltage between E2) summation be in general significantly higher than be used as protection outer member (master) light a fire route response it is electric
Pressure.
It is that igniter chamber utilizes two electrode and other combustion chamber high-insulations in this particular advantage.In addition, point
Fiery combustion chamber is until it is itself high-insulation (insulation resistance) and the self-capacitance with very little that it, which responds voltage,.Due to high
Insulation resistance (G ohm of ranges) and small self-capacitance, need lesser energy that igniter chamber is made to light a fire.It is lighting a fire when igniting
The electronics discharged in combustion chamber provides the response voltage of raising to adjacent combustion chamber, so that the insulation in these rooms is cut
Subtract and the external voltage by applying also makes adjacent combustion chamber ignition.
In this igniter chamber in order to which the igniting of optimization can be symmetrically positioned between adjacent combustion chamber (Fig. 1).Symmetrically
Construction can provide the advantage that i.e. inflatable overvoltage arrester USE need not be marked to install about its direction.
