Dc high-voltage source is for provide required high pressure along pulse shaping circuit by force soon.Dc high-voltage source is the set of equipments of ordering.Dc high-voltage source converts the 50Hz/220V alternating current into high direct voltage.Dc high-voltage source has voltage-operated device, digital voltage indicating device, interlocking (wait for, wait to send out) device and automatic protection (overcurrent protection) device.Voltage-operated device comprises " voltage amplitude " control handle and " enabling " button." voltage amplitude " control handle is used to regulate the amplitude of output high direct voltage, and the output ceiling voltage is 100kV (maximum current 2mA); " enable " button and whether be used to control high direct voltage through electrode output.When not pressing " enabling " button, electrode does not have high direct voltage output; When pressing " enabling " button, electrode output high direct voltage, dc high-voltage source is bipolarity output.The digital voltage indicating device is used to show that dc high-voltage source is provided with the size of output voltage.Interlock comprises waits for and waits to send out two states, and carries out the state indication through corresponding pilot lamp.Use " voltage amplitude " control handle to set the dc high-voltage source output voltage; Dc high-voltage source is not exported the voltage of setting numerical value at this moment, sets high pressure (a series of rectification and voltage multiplier treatment circuit realization finally is provided with voltage needs a period of time) but just export behind the about 30s of wait.Configure the dc high-voltage source output voltage through " voltage amplitude " control handle, this moment, state be " wait " state, and it is inoperative " to enable " button at this moment, promptly no matter whether presses " enabling " button, and the electrode of dc high-voltage source does not all have high direct voltage and exports.Have only about 30s of wait, after circuit completion voltage was provided with, state exchange " enabled " button at this moment and just acts on for " waiting to send out " state.Automatic safety device is used for overcurrent protection, and promptly when reasons such as external circuit short circuits, when causing the dc high-voltage source output current to arrive to a certain degree greatly, system protects---outage automatically, avoid accidents such as breaking out of fire.
Be used to produce the high-voltage transient highfield along pulse generating circuit soon by force.Like Fig. 2; The opposite end of air gap spark switch is provided with draft tube interface and escape pipe interface, and the other opposite end of air gap spark switch is connected with positive electrode E+ and negative electrode E-respectively, and positive electrode E+ is made up of electrode and positive external electrode in the sun; Negative electrode E-is made up of electrode in cloudy and cloudy external electrode; The opposite end of air gap spark switch K is provided with draft tube interface K1 and escape pipe interface K2, the positive electrode E of said air gap spark switch K and the noninductive capacitor C of first high-voltage pulse+be connected, and the negative electrode E-of said air gap spark switch K and the noninductive capacitor C of second high-voltage pulse-be connected; R-, R+ discharge and recharge current-limiting resistance; C-, C+ discharge and recharge the noninductive electric capacity of high-voltage pulse, and K is the air gap spark switch, and R0 is the equivalent d.c. resistance of electric field radiation device.When air gap spark switch K broke off, high direct voltage positive pole+U0 charged to C+ through R+, and negative pole-U0 charges to C-through R-and R0 simultaneously; The polarity of voltage is seen shown in Figure 2, and the size of voltage is U0, when trigger pip is connected K; C1 just becomes series connection, series voltage U with C2
RSize is 2U0, series voltage U
RCarry out effluve through R0.In effluve moment, the electric field radiation device produces by force soon along electromagnetic pulse.The electric field radiation device is made up of cable and power resistor, and effluve moment, the big electric current radiation of the transient state of passing through on cable strong-electromagnetic field constitutes the optimal discharge loop through power resistor, makes the undistorted transmission of signal, reduces reflection.
Like Fig. 3, it is interconnected to adopt special-purpose brace to carry out core devices K, C+, C-, guarantees that the core devices rigging position is compact especially; Interconnected ten minutes is reliable, and interconnected impedance is very little, and equivalent series inductance is extremely low; Arrive thus and trigger moment, compole short (tens nanoseconds) during effluve.Because of capacitor appearance value is bigger, the duration of charging is longer, and it is also longer that the air gap spark switch bears the high-tension time, thus adopt special-purpose air gap spark switch (see figure 4) to guarantee that the probability of generation self discharge during bearing high voltage is extremely low, to guarantee the integrity of final load.Because of on discharge instantaneous power resistance, bearing tens thousand of volt high pressure, adopt specific series-parallel system to carry out dividing potential drop, guarantee the work of resistance reliable and stable.Core devices K, C+, C-are placed in the casing of insulating material making, soak full insulating oil in the casing, prevent that air gap spark switch electrode, capacitance electrode, special-purpose brace, dc high-voltage source wiring input are in point discharge each other when being full of high pressure.
Like Fig. 4; The air gap spark switch is an airtight cavity; Passing on left tracheae is connected with charging valve; The right side is connected with the venting valve through tracheae, and upper electrode is connected with the noninductive electric capacity of high-voltage pulse through special-purpose brace, and lower electrode is connected with the noninductive electric capacity of another high-voltage pulse through special-purpose brace; Be full of specific gas according to certain pressure for air gap spark switch inside, apply high voltage to two electrodes about the air gap spark switch simultaneously, because the insulativity of gas; Two not conductings of electrode up and down; High direct voltage is constant on the maintenance electrode, and the gaseous tension that reduces suddenly in the air gap spark switch arrives certain numerical value, and internal gas is by high voltage ionization; Produce electric arc, produce electric arc moment two electrode conductions.Electrode conduction moment, two inter-electrode voltages sharply reduce because of discharge, and because of voltage reduces, gas is ionization no longer, no longer conducting of air gap spark switch like this.Air gap spark ON time is short, bears the voltage height, and discharge current is big, is specially adapted to by force soon along the electromagnetic pulse circuit.
Trigger control device such as Fig. 5, the reduction valve input end is connected with gas cylinder, and output terminal is connected with charging valve through tracheae.Specific compression gas is housed in the gas cylinder, and pressure is higher, and pressure gas at first is adjusted to the suitable gas of pressure through reduction valve.When charging valve was closed, the gas of reduction valve output can not get into the air gap spark switch.When charging valve was opened, the gas of reduction valve output got into the air gap spark switch through charging valve.Mechanical switch one termination 220V/50Hz civil power, a termination charging valve control end.Mechanical switch is pressed, and civil power flows through the charging valve control end through mechanical switch, and charging valve is opened.Mechanical switch is not pressed, and the charging valve control end does not have electric current to pass through, and charging valve is closed.Telepilot is controlled unlatching, the closure state of venting valve through the signal response device.When current venting valve is closure state, click button on the telepilot, signal response device control venting valve opening; Click button on the telepilot again, signal response device control venting valve closes, so repeatedly.During the venting valve opening, the air gap spark switch is through the venting of venting valve, and the gaseous tension in the air gap spark switch can reduce suddenly.During the venting valve closes, gas can not be emitted in the air gap spark.
The signal response device receives the wireless trigger signal that telepilot sends, unlatching, the closure of control venting valve.Like Fig. 6, the signal response device is made up of power circuit, signal receiving circuit, signal conditioning circuit, level equalization circuit.Power circuit converts the 220V/50Hz civil power into low-voltage dc power supply.
Power circuit passes through the state of relay control venting valve simultaneously, the control signal of power circuit input signal responsor, the break-make of this control signal control power circuit internal relay.Unlatching, the closed action of this relay on-off control venting valve.Receiving circuit receives the wireless control signal that telepilot sends, and carries out small-signal and amplifies.Signal conditioning circuit receives that with receiving circuit trigger pip is adjusted to the signal of particular polarity, amplitude, pulsewidth.It is level signal that the level equalization circuit is exported pulse transition with signal conditioning circuit, pulse each, and electrical level polar overturns once.With this level signal control power circuit internal relay action.
Like Fig. 7, whole telepilot is through a joint dry cell power supply, and telepilot is in off-mode at ordinary times, and do not produce any signal this moment, do not have power consumption yet.Have only when remote controller buttons S1 presses, circuit powers on, and just understands the radiation trigger pip, and trigger pip is a frequency signal.Transistor Q1 is used for " triggering frequency signal " starting of oscillation, and transistor Q2, Q3 amplify oscillator signal and feed back to transistor Q1, make the oscillator signal amplitude-frequency stable.Transistor Q1, Q2, Q3 are NPN type triode, and all as common-emitter amplifier.After switch S 1 closure, battery provides Dc bias through resistance R 1, inductance L 1 for transistor Q1 collector, is that transistor Q1 base stage provides Dc bias through LED 1, resistance R 2, R6, guarantees that transistor Q1 is operated in magnifying state.Battery provides Dc bias through LED 1, resistance R 2 for transistor Q2 collector, for transistor Q2 base stage Dc bias is provided through resistance R 3, guarantees that transistor Q2 is operated in magnifying state.Battery provides Dc bias through resistance R 4 for transistor Q3 collector, for transistor Q3 base stage Dc bias is provided through resistance R 5, guarantees that transistor Q3 is operated in magnifying state.Capacitor C 1, C2, inductance L 1 and transistor Q1 junction capacity are formed oscillatory circuit.This oscillatory circuit output waveform is poor, amplitude unstable (this oscillatory circuit output millivolt level oscillator signal, and a large amount of burrs of stack on the oscillator signal, this oscillator signal needs further rectification to amplify).This oscillator signal gets into transistor Q3 base stage through resistance R 6 with coupling capacitance C4;, transistor Q3 gets into transistor Q2 base stage after amplifying through coupling capacitance C3; After transistor Q2 amplifies; Give off the trigger pip (output 2.9kHz, 9V oscillator signal) of fixed-frequency, amplitude stabilization from transistor Q2 collector pin.Oscillator signal from the output of transistor Q2 collector pin feeds back to transistor Q1 base stage through resistance R 6 simultaneously.
Like Fig. 8, signal response device power circuit input 220V/50Hz civil power, output low-voltage dc power supply VCC2, VCC2 give the signal response device other functional circuit power supply after the further filtering of coupling capacitance C6.The PWR-CNT of power circuit input simultaneously signal (level equalization circuit output PWR-CNT signal), pilot relay K1 adhesive, disconnection.OUT-L and OUT-N connect the control end of venting valve.When PWR-CNT is high level, the Q7 conducting, the DC voltage of bridge rectifier circuit output arrives ground through relay K 1 control end, LED 2, Q7.This moment, LED 2 was bright, and relay K 1 adhesive has the alternating current of 220V/50Hz between OUT-L and OUT-N.When PWR-CNT was low level, Q7 ended.This moment, LED 2 went out, and relay K 1 is broken off no-voltage between OUT-L and OUT-N.The 220V/50Hz civil power is introduced the signal response device through IN_L and two nodes of IN_N; Diode D1, D2, D3, D4 constitute bridge rectifier circuit, at the positive half cycle of u1, because the current potential that IN_L is ordered is higher than the current potential that IN_N is ordered; So diode D1, D3 conducting, D2, D4 end; At the negative half period of u1, because the IN_N current potential of ordering is higher than the current potential that IN_L is ordered, so diode D2, D4 conducting, D1, D3 end.Between bridge rectifier circuit output terminal and ground, meet a high capacity electrochemical capacitor C5, the ripple in the output of filtering bridge rectifier circuit makes the direct current of pulsation become level and smooth direct current.Capacitor C 5 has the effect of store electrical energy, and when the voltage of power supply supply raise, the capacitor C 5 of parallel connection can store portion of energy; And when supply voltage reduces; Capacitor C 5 discharges energy stored again, make load voltage smoother, thereby AC ripple reduces greatly.The output of bridge rectifier circuit is after capacitor C 5 filtering, and DC voltage is higher, meets a high-power resistance R7, utilizes the direct supply voltage VCC2 of the dividing potential drop effect adjustment commutating voltage of resistance R 7 for actual needs.
Signal receiving circuit such as Fig. 9, after RPB S1 (see figure 7) was pressed, sensing chip ANT received the wireless control signal that telepilot sends, and carried out small-signal through Technitron Q4 and amplified, and produced the S-CNT signal.Direct supply VCC2 provides Dc bias through resistance R 8, sensing chip ANT, resistance R 9 for transistor Q4 collector, is that transistor Q4 base stage provides Dc bias through resistance R 10, R11, guarantees that transistor Q4 is operated in magnifying state.The filtering of 11 pairs of Q4 base stages of capacitor C Dc bias.Capacitor C 7, C8 and sensing chip ANT select wireless control signal, and capacitor C 9 provides feedback network, guarantee that signal amplification factor is stable.Capacitor C 10 bypass high-frequency interferencing signals avoid interference signal and get into triode, improve signal quality.
Signal conditioning circuit such as Figure 10, S_CNT get into integrated circuit U1 and carry out signal condition.U1 inside comprises two operational amplifier U1A and U1B.U1A carries out voltage amplification, and U1B carries out voltage ratio.Resistance R 12, capacitor C 12, C13, resistance R 13 are formed inverting amplifier, amplify the S_CNT signal.Wherein resistance R 13 is a feedback resistance, and resistance R 12 decay undesired signals utilize capacitor C 12 at a distance from straight effect, stops direct supply VCC2 to get into integrated circuit U1 through resistance R 8 (see figure 9)s, resistance R 12, and capacitor C 13 filterings are superimposed upon the high frequency clutter on the S_CNT signal.Because the average weight of S_CNT signal charges to C13, C13 is gone up produce pressure drop, on 3 pin of U1, can apply Dc bias like this.Resistance R 14, R15 are to the direct supply VCC2 dividing potential drop of connecting; The last DC voltage of R15 is introduced 2 pin of U1; The Dc bias on 3 pin of U1 is offset in linear superposition effect through integrated transporting discharging U1A, makes to put U1A through transporting something containerized and the S_CNT signal is not had direct current biasing amplify (in fact U1A voltage amplification output pin can be exported a small direct current biasing).Utilize capacitor C 14 separated straight effects, stop the last 1 pin output of amplifier U1A flip-flop to be passed through, " amplified signal of S_CNT " exported for last 1 pin of amplifier U1A provides path." amplified signal of S_CNT " that resistance R 16, R17 transmit C14 carried out the amplitude adjustment; Obtain suitable amplitude at R17, utilize the charging effect of capacitor C 15, take out the signal averaging component on the R17; This average weight gets into integrated transporting discharging U1B; Compare with reference voltage, obtain criteria triggers level (pulsed quantity), reference voltage obtains the direct supply VCC2 dividing potential drop of connecting through resistance R 18, R19.When remote controller buttons S1 (see figure 7) was not also pressed, the 6 pin level of U1 were lower than in reference voltage, 7 pin output high level.After RPB S1 pressed, the 6 pin level of U1 were higher than reference voltage, 7 pin output low levels.The duration that staff is pressed remote controller buttons is 0.2～0.9s, and remote controller buttons is upspring automatically afterwards, therefore in fact whenever clicks remote controller buttons, and 7 pin of U1 can be exported a spike pulse signal T-CNT (negative pulse).
Like Figure 11, level equalization circuit input T-CNT signal, output PWR-CNT signal, the level equalization circuit is received a T-CNT signal, output low level PWR-CNT signal; Receive a T-CNT signal again, output high level PWR-CNT signal.So repeatedly.Everyly come a T-CNT signal (negative spike pulse signal), trigger the bistable circuit of forming by Q5, Q6, make its upset (suppose Q6 previous status end) through isolating diode D5, D6; The Q5 conducting; The PWR-CNT output low level is pressed until telepilot once more, and Q6 becomes conducting again; Q5 ends, and PWR-CNT exports high level.Whenever telepilot is pressed once more, sensing chip is received signal one time later on, and the PWR-CNT signal level is overturn once.
