Description

technical field [0001] The invention relates to the application field of pyrotechnics, in particular to a delayed ignition device. Background technique [0002] An electric detonator is an industrial detonator that explodes by converting electrical energy into heat energy. It is made of a fire detonator and an electric ignition element. It is generally used in blasting operations in places with gas, coal dust or other combustible dust explosion hazards, and is also widely used in various blasting projects such as general mining, digging tunnels, building roads and bridges, and building water conservancy. In the blasting network, multiple generator detonators are connected in series, receive the high-voltage pulse signal sent by the electric detonator detonator to ignite, and realize the delayed detonation according to the delay body inside the detonator. [0003] A magnetoelectric detonator is a detonator excited by electrical energy generated by electromagnetic induction. ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned detonators control the delay time through the length of the internal delay charge, the delay accuracy is poor, and the delay charge contains a large amount of lead, which will cause certain lead pollution during the use of the detonator

[0005] In addition, after the existing detonators are networked, as long as they receive the high-voltage detonation signal sent by the external detonator, they will start to start and then complete the detonation, which has low safety.

At the same time, in the existing detonator network, because it is impossible to detect the connection reliability of the detonator in the access network, there is a phenomenon of blind fire of the detonator caused by the unreliable connection of the detonator, which further reduces the safety of the use of the detonator
