FIELD: instrumentation. SUBSTANCE: proposed electric spark pulse continuity detector is related to electric measurement instruments, specifically to devices testing continuity of dielectric coats on metal base. Detector includes power supply unit of storage circuit 1, discharger unit 2, synchronization pulse generator 3, logic AND gate 4, output transformer 5, probing electrode 6, signal-to-noise discriminator 7, logic storage location 8, unit 9 of output actuators and delay element 10. EFFECT: decreased energy losses both for arc discharge and "short-circuit" discharge of probing electrode to "ground" with exclusion of power elements of detector from excessive current, provision for high noise immunity and reliability of detector during process of its usage. |
