The short-circuit switch of the invention is composed of 4 parts such as a switch shell, a switch upper cover, a switch ejector rod, a switch spring and the like. The short-circuit switch is in a closed state at ordinary times, and is reliably opened when the switch ejector rod is subjected to upward axial pressure. The short-circuit switch is connected with the two leading-out wire ends of the electric ignition tube to form a short-circuit safety, so that the electric ignition tube can be ensured to be subjected to rear seat impact overload less than 10000g or the resistance between the two leading-out wire ends of the electric ignition tube is less than 0.5 omega under the condition of the rotating speed less than 10000r/min, and is in a safe state and no accidental explosion accident occurs. The magnetic core component is limited by the supporting lugs and the supporting rings, and can not move when being subjected to axial impact of less than 10000g, so that the magneto cannot generate electricity. Can ensure the safety of storage, transportation and service treatment processes.
When the invention is launched, the flame of primer 10 ignites the cartridge launch charge; the firing charge burns to generate high-temperature and high-pressure gas, so that initial speed of the projectile is endowed, meanwhile, the conduction band 12 is embedded into the gun rifling to guide the projectile to rotate at high speed, the conduction band 12 ensures that the projectile is embedded into the rifling during loading, the required rotating speed of the projectile is endowed during firing, the gunpowder gas is sealed, the predetermined muzzle speed and rotating speed are obtained at the moment when the projectile flies out of the muzzle, and after firing, the magneto generator generating circuit works, and meanwhile, the inertia pin acts to release the first-stage insurance; when the rotating speed is higher than 12000r/min, the centrifugal block is disconnected, the isolating rotor rotates under the action of torsion spring force, the isolating rotor is locked after rotating in place, the explosion isolation is released, the explosion propagation sequence is conducted, and the second-stage safety is released. After the two-stage safety is relieved, the electric energy isolation safety of the electric ignition tube is relieved, and the electric ignition tube is in a state to be exploded.

And after the electric energy output by one path is subjected to voltage limiting protection treatment, charging the ignition capacitor, releasing the electric energy when the electronic switch is opened, and detonating the electric ignitron. The other path of electric energy is charged to the energy storage capacitor after voltage limiting protection treatment, and the other path of electric energy is supplied to the control chip after voltage stabilizing treatment, so that timing is started, and an ignition instruction is output to the electronic switch at a set time point; and when the power is on for 5 seconds, a remote-unlocking instruction is sent to the control chip, and the control chip releases the locking safety of the output end. Only after the locking of the output end is released, the control chip can possibly output an ignition instruction, so that the safety of a muzzle during the launching can be ensured.
When the set time (10.5 s or 15 s) is reached, the control chip outputs an ignition instruction, the electronic switch is turned on, the ignition capacitor discharges, the electric ignition tube is detonated, the power tube is detonated, and then the elastomer charge in the elastomer is detonated to form an explosion effect, so that disastrous hail in a cloud layer is dispersed, and the high-efficiency catalyst contained in the elastomer has a remarkable effect on the drop of the cloud in the rain accumulation cloud.
