Accompanying drawing is block diagram of the present utility model.
The specific embodiment
As shown in drawings, the utility model is made up of voltage-stabilized power supply circuit, dc source, power display circuit, inverter circuit, charging display circuit, voltage-multiplying circuit, accumulator, cocking circuit.
Voltage-stabilized power supply circuit is to convert alternating current to direct current, is made up of transformer, rectifier bridge, filter capacitor, Voltage stabilizing module, is universal circuit, and wherein transformer is isolated for initiator provides primary power source.It and initiator are separately made, and partial installation can connect by socket.
Dc source (battery) provides dc source for initiator.
Power display circuit connects switch by dc source, and switch connects current-limiting resistance, and current-limiting resistance connects light emitting diode.When switch conduction, light emitting diode is bright, expression dc source operate as normal.
Inverter circuit is made up of two high-frequency triodes, electrochemical capacitor, resistance, contravariant transformers.Dc power anode connects E level and the electrochemical capacitor positive pole of high-frequency triode, the electrochemical capacitor negative pole connects the mid point of contravariant transformer feedback winding, contravariant transformer feedback winding mid point is connected to the mid point (also being the negative pole of dc source) of contravariant transformer inversion winding again by resistance, the two ends of inversion winding connect the C level of two high-frequency triodes respectively, and the B level of high-frequency triode is connected to the two ends of feedback winding.Two triodes take turns conducting and form the vibration inverter circuit behind power turn-on, and DC voltage is transformed into alternating voltage.Wherein contravariant transformer provides secondary isolation for initiator, has prevented the interference of high-frequency signal to tester effectively.
Voltage-multiplying circuit is made up of two diodes, and diode connects the two ends of contravariant transformer secondary windings in the inverter circuit respectively, in turn to two big electric capacity chargings of high pressure, thereby forms multiplication of voltage.
Accumulator is made up of electrochemical capacitor, connects two multiplication of voltage diodes respectively, the energy of storage multiplication of voltage.
Cocking circuit is initiator again, (be two moving switches of two secos of opening by playing voltage flame proof switch, can guarantee that when not detonating the percussion pin is not charged), the percussion pin forms, and plays positive pole, negative pole that the voltage flame proof switch front end connects electrochemical capacitor in the accumulator respectively, play a voltage flame proof switch rear end and connect the two poles of the earth of pulling the trigger pin respectively.When detonating switch conduction, the energy that is stored in the accumulator electrochemical capacitor will abrupt release, produces the electrical initiation detonator.
The charging display circuit is made up of diode, resistance, light emitting diode.Diode cathode connects an end of the low pressure winding of the contravariant transformer secondary windings in the inverter circuit, negative pole connects resistance, resistance connects light emitting diode, and the light emitting diode negative pole connects the other end of the low pressure winding of the contravariant transformer secondary windings in the inverter circuit.When inverter circuit was worked, voltage-multiplying circuit charged to accumulator, and light emitting diode has secretly and brightens, and the expression charging is finished and can be detonated.
