The invention relates to a high-
voltage constant-current exploder for an industrial electronic
detonator series network, comprising a high-
voltage constant-current power supply arranged in an inner container and used for providing high-
voltage constant-current output, a high-voltage
electronic switch for controlling the high-voltage constant-current output, a CPU (
Central Processing Unit) circuit for controlling the operation of the exploder, a low-voltage direct-current power supply for providing exploder input, an
ignition switch for controlling the opening / closing of the exploder, an allowable region limiting circuit for limiting an operation region of the exploder and a self-destruction circuit for burning key electrical appliance elements and damaging all control programs when the inner container of the exploder is illegally opened, wherein the
ignition switch comprises two or more key switches which are sequentially connected in series and mutually independently controlled. By using the high-voltage constant-current exploder provided by the invention, management control for the exploder and explosion operation can be realized through a plurality of technical means such as double-key control, double-
cipher operation, allowable region limiting and illegal opening self-destruction, the exploder can be kept in a controlled state all the time, the safety and the reliability of the explosion operation can be improved.
