[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0015] See also Figure 1-2 The present invention provides a technical solution: a pneumatic grounding system for an impulse voltage generator, comprising more than two pulse capacitors 4. A set of slidable insulating transmission rods 2 extend through both ends of the pulse capacitors 4. The insulating transmission rods 2 are fixedly connected to a cylinder 1 fixed to the ground. The insulating transmission rods 2 are equipped with a number of conductive springs 3 equal to the number of pulse capacitors 4. The conductive springs 3 are positioned below the electrodes at both ends of the pulse capacitors 4. The expansion and contraction of the cylinder 1 drives the conductive springs 3 to short-circuit the electrodes at both ends of the pulse capacitors 4, releasing energy into the ground.
[0016] The distance between the conductive springs 3 is equal to the distance between the pulse capacitors 4, but is less than or equal to the stroke of the cylinder 1, so that the cylinder 1 can drive the conductive springs 3 and the two end electrodes of the pulse capacitor 4 to short-circuit.
[0017] Each cylinder 1 is equipped with a separate solenoid valve 7, connected in parallel with the air compressor 5. A shared air filter 6 is located between the solenoid valve 7 and the air compressor 5, and a separate pressure sensor 8 is located between the solenoid valve 7 and the cylinder 1. Compressed air from the air compressor 5 passes through the air filter 6 and is then delivered to the solenoid valve 7, which controls the air circuit. The solenoid valve 7 receives control commands to extend and retract the cylinder 1. An internal pressure sensor 8 monitors the internal pressure in real time and displays the current system operating status within the control system.
[0018] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
