| Zusammenfassung: | An electromagnetic induction part of a current sensor for high energy-gathering electric detonation comprises an annular coil support frame formed by insulation material; a metal coil is formed by winding on the annular coil support frame at turn intervals; and two ends of the metal coil extends outwards to form output ends of the electromagnetic induction part of the current sensor. The structure can resist against the impact of 50 kilo-ampere pulse current, is sensitive in induction of electromagnetic pulse with pulse period under 50 microns, so signals can be timely captured. |
