Problems solved by technology

The non-electric detonation method consumes a lot of materials and will fail to explode during the operation process. It is not suitable for detonating in areas with flammable gas. Traditional electric detonation uses resistance wire to generate heat to trigger the detonator, which has high environmental requirements and is not easy to operate in thunderstorm weather. Or detonation near the electrostatic field, and storage, transportation safety is low, for this reason, an induction detonation system is proposed

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.

Description

technical field [0001] The invention relates to the technical field of novel blasting, in particular to an induction detonation system. Background technique [0002] The detonating device is widely used in the field of civil blasting. It is responsible for detonating the detonator and then detonating the main explosive to realize remote control blasting. It plays an important role in the field of blasting. At present, the detonation methods can be divided into three categories: the first type of non-electric detonation method, which mainly detonates the detonator through the detonation index; the second type of electric detonation method, mainly ignites the gunpowder or the primer by heating the resistance wire to finally detonate the detonator; the third type Other methods of detonation. The non-electric detonation method consumes a lot of materials and will fail to explode during the operation process. It is not suitable for detonating in areas with flammable gas. Traditi...
