Benefits of technology

In this new design for an inductive detonations systems (IDS), there's no harmful electrical components that come into play during operation due to insulation or other factors such as rainwater damage from precipitation). Instead, these devices use a simpler but more secure mechanism called a metal tower inside their housing instead of relying solely upon direct connections between parts like pins or terminals. By placing a wire around certain points within the metal tower, which generates enough magnetic force when exposed to strong radio waves, they create localized areas where tiny currents occur causing them to produce heat quickly. These hot spots help trigger the IDES without any danger if someone tries to explode nearby. Additionally, because the metal section used in the detection process remains cooler than usual, prevention against accidental ignition also improves its reliability over time.

Abstract

The invention discloses a sympathetic detonation system. The sympathetic detonation system comprises a detonator outer shell, an initiating explosive, an insulation base, a metal column, a coil, a high-frequency alternating current generator and the like. A high-frequency alternating current is introduced into the coil wound around the detonator outer shell, and the metal column contained in the detonator outer shell is sympathetically heated; as the surface temperature can be rapidly increased through the skin effect, the temperature-sensitive initiating explosive is rapidly detonated to achieve the aim of detonating a detonator; related circuits are not in contact with the initiating explosive at all, and the dangerous condition of a fault explosion caused when static electricity is generated in the transportation or use process is avoided; in addition, the sympathetic detonator system can be suitable for multiple environments; as the requirement of temperature increasing of the metal column for the frequency of the current is special and cannot be influenced by thunderstorm weather and static electricity environments, the influences of surrounding power frequency circuits on the temperature of the metal column are tiny, the application range is wide, the structure is simple, and the cost is low.
