Abstract

The invention provides an electronic detonator system and a use method thereof. An exploder is connected with a rectifier bridge and an electronic detonator chip; a fourth connecting end of the electronic detonator chip is connected with one end of the capacitor C1; a fifth connecting end of the electronic detonator chip is respectively connected with one end of a capacitor C2 and one end of an ignition head YT; a sixth connecting end of the electronic detonator chip is connected with a grid electrode of the field effect transistor Q1; the other end of the capacitor C1 is grounded; the other end of the capacitor C2 is grounded; the other end of the ignition head YT is connected with the drain electrode of the field effect transistor Q1; the source electrode of the field effect transistor Q1 is grounded; the capacitor C1 and the capacitor C2 are completely isolated; the electronic detonator chip comprises an isolating diode, a first current-limiting resistor, a power supply module, a charging switch, a second current-limiting circuit and digital circuit logic; the charging switch is a field effect transistor Q2. The safety of the electronic detonator is improved, and the cost of the electronic detonator used in a low-temperature environment is also greatly reduced.

Description

technical field [0001] The invention relates to the technical field of blasting equipment, in particular, to an electronic detonator system and a method of using the same, in particular to an electronic detonator that is suitable for low temperature applications by combining a ceramic capacitor and a tantalum capacitor. Background technique [0002] Most of the existing electronic detonators use two small-capacity tantalum capacitors or one large-capacity tantalum capacitor as the energy storage capacitor. The energy of the capacitor must meet the requirements of delay and detonation in a low temperature environment at the same time, which is not only high cost, but also low in safety. If two small-capacity tantalum capacitors are used, the voltage of the first tantalum capacitor is much higher than that of the second tantalum capacitor, and the higher the voltage of the tantalum capacitor, the higher the manufacturing difficulty and cost; if a single large-capacity tantalum ...
