Need further exist for explanation, high pressure detonation chain 100 provided in this embodiment, working principle are as follows: high pressure detonation
When circuit 100 works, first by driving peripheral circuit 40 that the grid of field-effect tube 32 is made to be maintained at low level, i.e. 0V.Then
Apply operating voltage U to high pressure detonation chain 100 by power supply 10.At this point, field-effect tube 32 is in an off state.Storage capacitor
21 are in charged state, and the voltage at 21 both ends of storage capacitor is U.Due to having the first equalizing resistance 22 and the second equalizing resistance 23
The voltage that effect, first gas discharge tube 24 and second gas discharge tube 25 are born is U/2, less than gas-discharge tube itself
Puncture pressure voltage, therefore first gas discharge tube 24, second gas discharge tube 25 are not turned on.
When triggering, high level is applied by the grid that driving peripheral circuit 40 is field-effect tube 32 first, makes field-effect tube
32 conductings, at this point, the voltage transient at 23 both ends of the second equalizing resistance is 0, so that the electricity at 24 both ends of first gas discharge tube

Pipe 32 is in an off state, and storage capacitor 21 is in charged state, and the voltage at 21 both ends of storage capacitor is U.Due to have first
The effect of piezoresistance 22 and the second equalizing resistance 23, first gas discharge tube 24 and the voltage that second gas discharge tube 25 is born are equal
For U/2, less than the breakdown pressure voltage of gas-discharge tube itself, therefore first gas discharge tube 24, second gas discharge tube 25 are equal
It is not turned on.
When triggering, high level is applied by the grid that driving peripheral circuit 40 is field-effect tube 32 first, makes field-effect tube
32 conductings, at this point, the voltage transient at 23 both ends of the second equalizing resistance is 0, so that the electricity at 24 both ends of first gas discharge tube
Pressure becomes U from original U/2, and greater than the breakdown pressure voltage of first gas discharge tube 24, therefore, first gas discharge tube 24 occurs
Breakdown conducting.Due to the conducting of first gas discharge tube 24, so that the current potential at 22 both ends of the first equalizing resistance becomes isopotential point,
That is the current potential at 22 both ends of the first equalizing resistance is 0, and potential difference is also 0, thus the electricity that 25 both ends of second gas discharge tube are born
Pressure is U by 0 transition, so that breakdown conducting occurs for second gas discharge tube 25.
Therefore, the conducting of first gas discharge tube 24 and second gas discharge tube 25, it is of short duration form by storage capacitor 21,
