Abstract
The invention provides a protection circuit of a slapper detonator high voltage discharge switch. External voltage sampling signals on both ends of a first high voltage capacitor and external voltage sampling signals on both ends of a second high voltage capacitor are correspondingly passed into negative input ends of a first comparator and a second comparator; respective output feedback signals are correspondingly input to positive input ends of the first comparator and the second comparator; output signals of the first comparator and the second comparator are passed into the positive input end of a third comparator after an OR operation and reference voltage is passed into the negative input end of the third comparator; and the output signals of the third comparator and external multi-channel fuze output signals output a burst control instruction after an AND operation. The protection circuit of the slapper detonator high voltage discharge switch has the advantage of judging sizes of the voltage sampling signals on the both ends of high voltage capacitors and the reference voltage UR by utilizing the comparators to achieve the high voltage discharge switch control, protect the high voltage discharge switch and increase the using times of the high voltage switch.

Summary of the invention
The technical problem that solves
The problem that exists for solving prior art the present invention proposes a kind of protective circuit of impacting sheet detonator high-voltage discharging switch.Its mentality of designing is closed control circuit of design, and specifically high-voltage capacitor both end voltage (H) → output → comparison circuit of sampling → follow → high-voltage switch gear discharge control signal (H) → high-voltage switch gear closure → high-voltage capacitor both end voltage (L) → output → comparison circuit of sampling → follow → high-voltage switch gear discharge control signal (L) → high-voltage switch gear disconnects.
Technical scheme
Technical scheme of the present invention is:
Described a kind of protective circuit of impacting sheet detonator high-voltage discharging switch is characterized in that: the both end voltage collection signal of outside the first high-voltage capacitor and the both end voltage collection signal of the second high-voltage capacitor be the corresponding negative input end that passes into the first comparator and the second comparator respectively; The corresponding input of the positive input terminal of the first comparator and the second comparator output feedback signal separately; The output signal of the first comparator and the second comparator is through passing into the positive input terminal of the 3rd comparator behind the exclusive disjunction, the negative input end of the 3rd comparator passes into reference voltage; The output signal of the 3rd comparator and outside multichannel fuse output signal through with computing after the instruction of output initiation control.
Beneficial effect
The protective circuit that the present invention proposes realizes the control to high-voltage discharging switch with the size of comparator judgement high-voltage capacitor two ends sampled signal and reference voltage UR, plays the protection high-voltage discharging switch, improves the effect of high-voltage switch gear access times.

Embodiment
Below in conjunction with specific embodiment the present invention is described:
With reference to accompanying drawing 1, the protective circuit of the impact sheet detonator high-voltage discharging switch in the present embodiment, its input signal is outside both end voltage collection signal from the first high-voltage capacitor and the second high-voltage capacitor.The both end voltage collection signal of outside the first high-voltage capacitor and the both end voltage collection signal of the second high-voltage capacitor be the corresponding negative input end that passes into the first comparator and the second comparator respectively.The corresponding input of the positive input terminal of the first comparator and the second comparator output feedback signal separately.The output of the first comparator and the second comparator is connected to follow circuit.The output signal of the first comparator and the second comparator is through passing into the positive input terminal of the 3rd comparator behind the exclusive disjunction, the negative input end of the 3rd comparator passes into reference voltage; The output signal of the 3rd comparator and outside multichannel fuse output signal through with computing after the instruction of output initiation control.
Judge like this size of high-voltage capacitor two ends sampled signal and reference voltage UR by comparator N2, if sample greater than reference voltage in the high-voltage capacitor two ends, comparator N2 exports high level, otherwise, comparator N2 output low level.With the output of this comparator N2 and outside multichannel fuse output signal through with computing after the instruction of output initiation control.
