Abstract

The invention discloses a protection circuit suitable for an initiating explosive device on a two-stage ignition bomb. The protection circuit belongs to the technical field of safety protection of the initiating explosive device on the bomb, and solves problems of delayed explosion and poor direct protectiveness of the initiating explosive device caused by a safety protection mode of the conventional initiating explosive device on the bomb. The protection circuit comprises a protection control relay, a protection state detection circuit and a ground control circuit; one end of the protection control relay is connected with a negative power supply end Q of an ignition power supply; the other end of the protection control relay is connected with a negative activating end T of the initiating explosive device; a control signal input end of the protection control relay is connected with a control signal output end of the ground control circuit, and the control signal output end of the protection control relay is connected with the control signal input end of the protection state detection circuit. The protection circuit is suitable for safety protection of the initiating explosive device on the two-stage ignition bomb.

Description

technical field [0001] The invention relates to a protection circuit applicable to explosive devices on two-stage ignition bombs, and belongs to the technical field of safety protection of explosive devices on bombs. Background technique [0002] Whether the pyrotechnic product is fired normally is related to the success or failure of the test, and whether the safety protection measures for the pyrotechnic device are effective also relates to whether the test can be carried out normally. See image 3 shown. from image 3 It can be seen from the figure that the traditional protection method of pyrotechnics is to directly lead the active positive and negative terminals of pyrotechnics to the ground for short-circuit protection. The disadvantage of this protection method is that the protection line is long. Improper, there may be interference voltage, which may lead to wrong ignition of pyrotechnic devices, and poor direct protection; on the other hand, it cannot meet the timi...
