Abstract
Official abstract text for this publication.
A detonator installation (10) in which a detonator fire capacitor (36) which is connected in series with an inductor (18) is charged from a low voltage source (16) by repeatedly opening and closing a switch (20) thereby to cause a collapsing magnetic field in the inductor (18) which results in a charging current flow to the capacitor (36).
First claim
Opening claim text (preview).
The invention claimed is: 1. A detonator installation including control equipment, the control equipment comprising: a controller; a voltage source, an inductor and a switch connected in series with the voltage source; output terminals; and at least one detonator including a capacitor and at least one protective diode, the capacitor and the at least one protective diode being connected in series to the output terminals; wherein the controller is operable repeatedly to close the switch, thereby to direct current from the voltage source through the inductor which then establishes a magnetic field, and to open the switch so that the magnetic field collapses and generates a current which flows via the output terminals through the capacitor and the diode thereby to charge the capacitor. 2. A detonator installation according to claim 1 wherein the inductor is physically removable from the control equipment. 3. A detonator installation according to claim 1 including a voltage limiting protective device connected in parallel to the detonator, or in parallel to the output terminals.
