The utility model discloses a strong vibration sensor circuit and signal acquisition system for high voltage circuit breaker, circuit include electric charge voltage converting unit, second order lowpass filter unit and many grades of amplifying units, can receive the huge electric charge amount of high voltage sensor test high voltage circuit breaker's strong vibration signal production, even under the condition under electromagnetic environment is abominable, still can stably work. Electric charge voltage converting unit adopts the self discharge, has the integrating circuit who separates straight function, and many grades of amplifying units adopt the fixed resistances concatenation to shift, and the resistance value dispersibility is little, and the stepping is accurate, and designs the locator, offsets the dispersibility of sensor, solves under the high acceleration that the charge sensitivity is low, the poor defect of electromagnetic environment under the high voltage. The utility model discloses the electrical circuitry is simple, components and parts low cost, and design benefit is applicable to the occasion that the collection is vibrated by force, electromagnetic environment is abominable, is favorable to promoting.
