摘要： A plurality of electric blasting caps are fired through the ignition system which includes a transformer (19) having a primary winding (17) and a secondary winding (21). The secondary winding (21) of the transformer (19) is connected to the resistive elements (53) of the blasting caps (55) through a blasting circuit which is electromagnetically coupled to the resistive elements (53) of the blasting caps (55) via a small toroid transformer. A D.C. voltage is stored on a storage capacitor (3) which has one end connected to the center point (15) of the primary winding (17). The other ends of each half of the primary winding (17) are connected through a driver circuit (29) to ground. Each driver circuit (29) is enabled by a flip-flop (35) at predetermined intervals, whereby the storage capacitor (3) will discharge through the appropriate half of the primary, to thereby produce a pulse train at the output of the secondary. The pulse train provides the ignition power for igniting the electric blasting caps.
