Inductance LaUsing high-frequency inductor, inductance LaInductance be tens microhenrys.As reverse-blocking tetrode thyristor KbOr magnetic latching relay
Switch KcConducting moment, the impedance of electric capacity Ca is about 0, and due to inductance LaPresence, inductance LaIn conducting moment, its frequency becomes
Change very big, inductance LaImpedance it is also very big, it is suppressed that power supply turn on moment dash current；When normal circuit operation, due to
Supply frequency is 50Hz power frequencies, then inductance LaImpedance very little.
In inductance LaIn, inductance LaVoltage ULaAdvanced inductance LaElectric current I190 degree, i.e. inductance LaElectric current I1Fall behind electricity
Sense LaVoltage ULa90 degree.
In electric capacity C0In, electric capacity C0Electric current I2Advanced electric capacity C0Voltage UC090 degree, i.e. electric capacity C0Voltage UC0Fall behind electricity
Hold C0Electric current I290 degree.
Electric current I1By inductance La, electric capacity Ca formed closed-loop path, then have inductance LaOn voltage ULaAdvanced inductance LaOn
Electric current I190 degree.
As inductance LaVoltage ULaIn node M sometimeaPoint for just, node MbPoint for it is negative when, then electric current I2From node
MaPoint passes through diode D1, light emitting diode D5, diode D4With electric capacity C0Form branch road.
Ignore diode D1, light emitting diode D5With diode D4Pressure drop, it is clear that have i.e. ULa=UC0, i.e. inductance LaElectricity
Pressure ULaEqual to electric capacity C0Voltage UC0.Obviously there is inductance LaOn voltage ULaDelayed electric capacity C0On electric current I290 degree, so as to have
Electric capacity C0On electric current I2With inductance LaOn electric current I1Each other reversely, i.e. electric current I2With electric current I1It is reverse each other.UCNIt is on live wire C
Voltage.For sake of convenience, A phases, B phases are collectively referred to as into live wire with C phases.
As electric current I2It is positive and more than light emitting diode D5During luminous minimum current, the output signal U of photoelectrical couplerI0
It is changed into low level, reasonable selection electric capacity C from high level0, make electric capacity C0On electric current I2Positive going zeror crossing point and can be rapidly achieved send out
Optical diode D5Luminous minimum current.
As electric current I2After positive going zeror crossing point, the output signal U of photoelectrical couplerI0It is changed into low level from high level, due to
Electric current I2With electric current I1Reversely, then there is the output signal U when photoelectrical couplerI0When being changed into high level from low level, electric current I1Just
In positive going zeror crossing point.Therefore the output signal U of photoelectrical couplerI0When being changed into high level from low level, that is, obtain electric current I1
Zero crossing electric current.When obtaining electric current I1Zero crossing electric current when, controller can immediately give magnetic latching relay switch KcSend out
Go out to be opened or closed signal.Magnetic latching relay is allowed to switch K if desiredcDisconnect, then controller is just opened to magnetic latching relay
Close KcSend disconnection control signal, magnetic latching relay switch KcThen turn off；Magnetic latching relay is allowed to switch K if desiredcClose
Close, then controller just switchs K to magnetic latching relaycSend closure control signal, magnetic latching relay switch KcClose immediately.
From by obtaining correct time point during current zero-crossing point, K is switched to magnetic latching relay further according to the correct time pointcSend
The control signal being opened or closed make magnetic latching relay switch KcContact be opened or closed, then flow through magnetic keep relay
Device switchs KcElectric current it is little, be opened or closed in small current magnetic latching relay switch KcSo that magnetic latching relay switchs Kc
Contact be hardly damaged.So as to effectively extend magnetic latching relay switch KcLife-span, and then extend combination switch
Service life.
When combination switch is put into, because reverse-blocking tetrode thyristor KbThe moment of conducting, due to inductance LaElectric current inhibitory action,
Big dash current will not occur, and due to reverse-blocking tetrode thyristor KbConduction voltage drop very little, and inductance LaThe impedance under work frequency
Very little, node MaAnd node MbThe pressure drop of point-to-point transmission is less, now closes magnetic latching relay switch Kc, to magnetic latching relay
Switch KcContact infringement very little, so as to effectively extend control transwitch KbLife-span, and then extend the use of combination switch
Life-span.
In reverse-blocking tetrode thyristor KbIt is on and magnetic latching relay switch KcIn when closing, if to turn off controllable silicon
Switch Kb, then in electric current I1Just allow reverse-blocking tetrode thyristor K during zero crossingbDisconnect, so being capable of effective protection reverse-blocking tetrode thyristor KbMake
Use the life-span.
Only in the reverse-blocking tetrode thyristor K that combination switch is put into live wire CbWhen put into when just adopting voltage over zero, only
Want all to be put into or cut off using current over-zero in the case of having electric current on combination switch, substantially increase combination switch
Service life, reliability is higher, and safety is preferable.
As reverse-blocking tetrode thyristor KbDuring conducting, in magnetic latching relay K is switchedcIn the case of being also not turned off, magnetic now is protected
Hold relay switch KcIt is also conducting, you can control transwitch KbK is switched with magnetic latching relaycNow it is on shape simultaneously
State.Due to reverse-blocking tetrode thyristor KbBranch road has inductance LaConducting resistance, it is clear that magnetic latching relay switch KcThe impedance of branch road will
Far smaller than reverse-blocking tetrode thyristor KbThe impedance of branch road, therefore flow through magnetic latching relay switch KcElectric current more than flowing through controllable silicon
Switch KbThe electric current of branch road.If magnetic latching relay switchs KcNot in current zero-crossing point break contact, contact is easily damaged.From logical
Cross acquisition inductance LaThe electric current I of branch road1Correct time point during zero crossing, then allow controller to send control signal to disconnect magnetic guarantor
Hold relay switch KcContact, allow magnetic latching relay switch KcClosed when electric current is less or disconnection action, thus
Easy burn-out magnetic latching relay does not switch KcOn contact, effectively extend magnetic latching relay switch KcService life, enter
And the service life of combination switch is also extended, simple structure, reliability is high.
