SYSTEM FOR PROGRAMMED INITIATION OF ELECTRICA DETONATOR NETWORKS

摘要

System consists of the following: an initiating device (UI) as a machine for initiation of the electrical detonator network with programmable delay times. Delay times are set by hexadecimal switches and the set values of delays can be read out visually of each UI individually. Connection of the 16 UIs with the single control and supply device (UUP) is provided. Each UI is connected by five-wire connection for supplying electrical power from 12 V, 1.3 Ah battery in the UUP. The control and supply device has. a DC-DC converter for supplying electrical power for initiation having voltage Uc = 350 V to the condensers in the UI.
