The high-voltage center through rod 3 is supported in the cylinder 2 through a support block group, the support block group is made of insulating materials, and the support block group is hermetically connected with the high-voltage center through rod 3 and the cylinder 2.

The material of the cylinder 2 is 45 steel, and the 45 steel has high strength and is not easy to rust and can resist shock waves without deformation. The cylinder body 2 can be placed in a small circular hole to meet the requirements of field use, the high-pressure center through rod 3 is made of chromium-molybdenum alloy, and the chromium-molybdenum alloy has good conductivity and structural strength. The upper end threaded connection of transducer window 1 is in the lower extreme of barrel 2, and the stay block group adopts high molecular weight polyethylene, and high molecular weight polyethylene has good structural strength, can withstand the shock wave of huge pressure, still has good insulating nature simultaneously, and the stay block group is sealing connection with high-pressure center through-rod 3 and barrel 2, and consequently the device can carry out the shock wave test in aqueous. One end of a power supply is connected to the barrel body 2, the other end of the power supply is connected to the upper end of the high-voltage center through rod 3, then current flows to a metal wire between the load upper connecting end 5 and the load lower connecting end 4 to generate shock waves, and the shock waves act on a target through an opening in the side wall of the transducer window 1.

In this embodiment, the cylinder 2 includes an upper tightening ring 21, a central outer cylinder 22, a lower tightening ring 23, and a bottom connecting cylinder 24, which are connected in this order by a screw.

Sealing rings are arranged at the joints of the upper tightening ring 21, the central outer cylinder 22, the lower tightening ring 23 and the bottom connecting cylinder 24.

The outer walls of the upper tightening ring 21, the central outer cylinder 22, the lower tightening ring 23 and the bottom connecting cylinder 24 are all provided with blind holes 25, and the number of the blind holes 25 is more than one.

It should be noted that, the upper tightening ring 21, the central outer cylinder 22, the lower tightening ring 23 and the bottom connecting cylinder 24 are arranged in segments, which facilitates the installation of the support block set and well fixes the high-voltage central through rod 3.

In this embodiment, the support block set includes an upper insulator 6, an upper middle insulator 7, a lower middle insulator 8, and a bottom insulator 9, all mounted on the barrel 2.

The centers of the upper insulator 6, the upper middle insulator 7, the lower middle insulator 8 and the bottom insulator 9 are all provided with mounting holes, and the inner walls of the mounting holes are abutted to the side walls of the high-voltage center through rod 3.

It should be noted that, since the center of the cylinder 2, that is, the center outer cylinder 22, needs to be opened, the opened hole is a measurement position of the reserved voltage. The gap between the high-voltage central through rod 3 part at the central outer cylinder 22 and the voltage probe can be equivalent to a high-voltage end capacitor, and according to the principle of a capacitive voltage divider, the high-voltage end capacitor value is small, the capacitive reactance value is large, the low-voltage end capacitor value is large, the capacitive reactance value is small, and thus a proper low-voltage end signal can be measured at the low-voltage end. Therefore, the upper middle insulator 7 and the lower middle insulator 8 at the central outer cylinder 22 are not directly designed into an integral structure, but are divided into two parts, and a gap of 2cm is reserved, so that signals can be accurately measured.

If the gap at the central outer cylinder 22 is blocked by an insulator, the formula is followedIf the value of epsilon of the insulator is large, the capacitance value will be very large, the capacitance reactance value will become very small, and instead, a low-voltage end is formed, and the original low-voltage end becomes a high-voltage end, which is very unfavorable for signal measurement.

The bottom insulator 9 is used for separating the high-voltage center through rod 3 and the transducer window 1 so as to reduce the probability of direct discharge of the high-voltage center through rod 3 to the transducer window 1 as much as possible.

The device of the present invention achieves a completely rigid structure, substantially without concern for the possibility of internal discharge ablation when passing high currents. Simultaneously, the design of a plurality of insulators can isolate the high-voltage center through rod 3 from the cylinder 2, and the condition that the high-voltage center through rod 3 directly discharges the cylinder 2 during discharging is prevented.

The conventional high-pressure center through rod 3 can adopt a two-section type or three-section type structure, the high-pressure center through rod 3 with the two-section type or three-section type structure can be more convenient to mount and dismount, and the diameter of the high-pressure center through rod 3 can also be more conveniently controlled.

According to the invention, if the two-section or three-section high-voltage center through rod 3 is adopted, the huge charge quantity passing through the high-voltage center through rod 3 can quickly ablate the spring or threaded connection part, so that the high-voltage center through rod 3 directly discharges to the barrel 2, and the high-voltage center through rod 3 can drop off in serious conditions, and further the load device is scrapped in advance and other accidents are caused.
