2, select the course of work of little load power down function:

The 1st fork shift switch 7-1 is disconnected, and the 2nd coaxial fork shift switch 7-2 is closed, has selected little load power down function this moment.

The course of work is: press pushbutton switch 13, battery E is by the control utmost point of positive pole, limit switch XK, dropping resistor R0, pushbutton switch 13, the 4th resistance R 4 to the 1st thyristor BT1, and the negative pole of getting back to battery E by the negative electrode of the 1st thyristor BT1 again consists of triggering passage.The conducting that is triggered of the 1st thyristor, motor D gets electric, drives the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 closes cutter, is powered to electrical equipment fR by electrical network.Pushbutton switch 13 is in parallel with the collector and emitter of the 1st triode BG1, and function is identical.When electrical equipment fR cut off or power little during to prior setting value, the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 just auto back cut off electrical network to original position, broaching tool outage with electrical equipment fR.

3, the course of work of control moving knife outage:

After electrical network is connected, arrived the other end of power supply by the 7th diode D7 of positive half cycle (setting just upper negative) through playing rectified action of line voltage, the LED that plays the work indicative function, the 10th resistance R 10, the 9th resistance R 9, the 8th resistance R 8, the 2nd diode D2, consist of the half-wave rectification path, on the 8th resistance R 8, the 9th resistance R 9, respectively tell a voltage, after the 8th resistance R 8 dividing potential drops the 3rd capacitor C 3 is charged.Owing to playing collector and the 3rd capacitor C 3 anodal in parallel of the 2nd triode BG2 of blockade effect, when electrical equipment fR connects, its working current is detected by the base stage of the 2nd triode BG2, the 2nd triode BG2 saturation conduction, this moment, the positive pole of the 3rd capacitor C 3 only had very low saturation voltage drop, motor D can't obtain voltage, and circuit keeps power supply state.After load cuts off, working current disappears, the 2nd triode BG2 loses base flow and transfers cut-off to, dividing potential drop on the 8th resistance R 8 is rapidly to 3 chargings of the 3rd capacitor C, the 3rd capacitor C 3 voltages rise until the 1st stabilivolt D1 punctures, electric current is just from the positive pole of the 3rd capacitor C 3, through the 1st stabilivolt D1, play the control utmost point of the 6th resistance R 6 to the 2nd thyristor BT2 of metering function, the negative pole of getting back to the 3rd capacitor C 3 by the negative electrode of the 2nd thyristor BT2 again forms and triggers the loop, the 2nd thyristor BT2 obtains the gate current conducting, the 3rd capacitor C 3 just by positive pole through motor D, the 2nd thyristor BT2 gets back to the negative pole of the 3rd capacitor C 3, the 3rd electric capacity is to motor D back discharge, motor D obtains an of short duration reverse power, promoting movable knife rack rotating shaft 27 rotates, drive the upper moving knife brace 28 of the 1st knife-like switch DK-1 and the lower moving knife brace 41 of the 2nd knife-like switch DK-2 and turn clockwise simultaneously 90 °, cut off simultaneously the normal opened contact C1 of the 1st knife-like switch DK-1, the normal opened contact C2 of intermediate contact A1 and the 2nd knife-like switch DK-2, intermediate contact A2, and connect simultaneously the normally closed contact B1 of the 1st knife-like switch DK-1, the normally closed contact B2 of intermediate contact A1 and the 2nd knife-like switch DK-2, intermediate contact A2, the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 broaching tool disconnects electrical network, and electrical network stops power supply to electrical equipment fR.

When selecting zero load power down function, the 2nd fork shift switch 7-2 disconnects, the base stage below-center offset resistance of the 2nd triode BG2 is that the shunting of 11 pairs of base flows of the 11st resistance R is less, the work of the 2nd triode BG2 is arranged on degree of depth state of saturation, so very little load can both stable power-supplying, just understand the broaching tool outage when only having the load of electrical equipment fR to approach zero.When selecting little load power down function, the 2nd fork shift switch 7-2 is closed, and the 1st adjustable resistance W1 is in parallel with the 11st resistance R 11, and total resistance reduces and base flow is shunted increasing, and this moment, the 2nd triode BG2 entered the amplification region.When load power significantly reduces (main frame enters standby), working current is corresponding reducing also, its variable quantity is detected by the base stage of the 2nd triode BG2, after amplifying, the conducting amount of the 2nd triode BG2 also significantly reduces thereupon, and the collector voltage of the 2nd triode BG2 rises rapidly, and the cathode voltage of the 3rd capacitor C 3 of joining with the 2nd triode BG2 also rises until the 1st stabilivolt D1 punctures thereupon, the 2nd thyristor BT2 obtains the gate current conducting, and motor D drives switch circuit breaking.Adjust the 1st adjustable resistance W1, can select to keep the minimum power of power supply.After the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 outage, connect normally closed contact B1, the intermediate contact A1 of the 1st knife-like switch DK-1 and normally closed contact B2, the intermediate contact A2 of the 2nd knife-like switch DK-2, because when selecting little load power down function, the interior resistance of electrical equipment fR is connected and is detected with battery control circuit all the time, battery control circuit will send electricity again, caused back and forth concussion between energising, the outage, therefore use and will follow the tracks of path with coaxial the 1st fork shift switch 7-1 of the 2nd fork shift switch 7-2 and cut off, employing button or remote control start during work.

4, keep the testing process of the testing circuit of power supply and cut-out power supply:

Keeping power supply and cutting off power supply is the working current of detection load.

When selecting without the lotus power down function, in the situation of bearing power less than 0.1W, its electric current is in microampere order.Because the detection shunt is the 5th diode D5 by two shunting actions that have been in series, the 6th diode D6 forms, its impedance is two knot electric fields, about 1.4V, with the 5th diode D5, in blockade the 2nd triode BG2 input circuit that the 6th diode D6 is in parallel, only has an emitter junction electric field, about 0.7V, resulting impedance is less than the shunt resulting impedance, when load current is very little, so that the i.e. pressure drop of the 12nd resistance R 12 of the base resistance of the 2nd triode BG2 is less than 0.7V, electric current all flows to the input circuit of the 2nd triode BG2, and the 2nd triode BG2 saturation conduction blocks the charging circuit of capacitor C 3.When constantly increase of load, when working current also increases thereupon, voltage drop on the 12nd resistance R 12 is risen thereupon, when being raised to 0.7V and have above trend, the 5th diode D5, the 6th diode D6 conducting, under the characteristic of diode forward constant voltage, the base voltage of the 2nd triode BG2 is by constant, and the later electric current that increases is shunted by the 5th diode D5, the 6th diode D6.When selecting little load power down function, because the 2nd triode BG2 is operated in the amplification region, load power significantly changes and causes the thereupon variation of working current, and the height that causes being blocked voltage is followed variation, select suitable working point, just can select to keep the minimum power of power supply.

Since line voltage in different regions, Various Seasonal, the fluctuation of different period be very large, in the situation that voltage is very low, may cause on the 8th resistance R 8 dividing potential drop excessively low, so that the utility model can not normal power down.When voltage became suddenly very high, because charging current changes by law of indices, initial velocity was very fast, and load current changes by direct proportion, and the potential dividing potential drop on the 8th resistance R 8 also rises very highly, and blockade may be overturned, and causes load to cut off the power supply because of malfunction at work midway.Therefore in circuit, added the mu balanced circuit that is consisted of by the 3rd stabilivolt D3.The course of work is: with the 3rd stabilivolt D3 the 8th resistance R 8, the 9th resistance R 9 are stabilized in the working range for when the 8th resistance R 8, the 9th resistance R 9 dividing potential drop enough voltage storage level, in the 8th resistance R 8 normal work dividing potential drop are arranged when very low with the assurance line voltage.When line voltage rises very highly, because the charging voltage on the 3rd capacitor C 3 is held, and load current increases in proportion, strengthen so that block the 2nd triode BG2 the 2nd triode BG2 conducting amount, the voltage follow decline that the collector voltage of its 2nd triode BG2 descends and causes the 3rd capacitor C 3, form like this a negative-feedback circuit, guaranteed reliably the steady operation of circuit.Because the 3rd stabilivolt D3 offset of sinusoidal ripple is cut the top effect, in order to improve effective charging voltage, the 4th capacitor C4 in parallel on the 3rd stabilivolt D3, power supply is filtered into direct current, to improve charge efficiency, after the mu balanced circuit access, can be adapted to voltage in the variation range of 100V-270V.

5, the 1st triode BG1 is the output phase-reversing tube of infrared remote control receiver IRM because infrared remote control receiver IRM output is negative pulse, and the 1st thyristor BT1 to trigger what need be positive pulse, so must paraphase.

The course of work is: infrared remote control receiver IRM is when static state, be output as high level, its numerical value is near supply voltage, so that the 1st triode BG1(PNP type) base stage and emitter equipotential and be in zero state partially, the 1st triode BG1 cut-off, the 1st thyristor BT1 blocking-up, motor D does not work.After infrared ray receiver of remote-control sytem IRM receives signal, infrared remote control receiver IRM exports negative pulse, amplitude is several volts at zero point, the emitter current potential of the 1st triode BG1 is higher than base potential and forms base flow, the 1st triode BG1 conducting, the collector current after the amplification be by the 4th resistance R 4, for the control utmost point of the 1st thyristor BT1 provides gate current, the 1st triode BG1 conducting, motor D obtains voltage and drives the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 and close cutter power supply.

Because circuit triggers is a simple DC channel, the requirement of not free and electrical angle, more need not reading out data, therefore, utilize its carrier wave to trigger, carrier widths far surpasses the sincere firmly time of thyristor, reliably conducting is so can by the remote control transmitter of household electrical appliances self, press any one function key and can trigger, because the remote control transmitter of general household electrical appliances can both be received work, so need not join dedicated transmitter.

After the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 dropped into powered operation, limit switch XK cut out circuit to avoid unnecessary consumption with battery E.Distant control function is mainly used in watching TV, particularly watches before and after the sleep, and start, shutdown reach Full remote controlled, use ten parts of convenience.Computer need not to use remote control owing to operating before screen, therefore remote-controlled power switch 12 can be disconnected, and to reduce the static power consumption of Receiver, makes the utility model become fully zero consumption standby, adopts pushbutton switch 13 starts during work.

Behind the load place in circuit, if during 1 selection idling lotus power down function, keep for power detection circuit and will detect its internal resistance, so that battery E by battery control circuit automatically for mechanical actuating mechanism provides a power supply, motor D outputting power promotes the 1st knife-like switch DK-1, the 2nd knife-like switch DK-2 and is load power supply.After the load operation, detect blockade shutoff testing circuit thereby its working current is turned off testing circuit, keep the power supply to load.When 2, selecting little load power down function, after pushbutton switch 13 or infra-red remote control started, the load operation electric current was detected equally and keep power supply.When outer load was cut off or uses power significantly to be reduced to setting value, breaking circuit blocks to be removed, and control circuit provides an of short duration reverse voltage for motor, and motor is just exported an of short duration reverse power, promotes knife-like switch with dump.

No-load consumption during for fear of self standby of the present utility model and being struck by lightning, thereby the utility model thoroughly breaks away from electrical network take battery as power supply, because thyristor does not have electric current to flow through when blocking-up, only need add a voltage, so the utility model power consumption when standby is zero.Motor D is in when work and since the time compole short, electric current is little, battery E discharge rate is very low.Battery E once can use long time, calculates with average every day of ten starts, and motor D work T.T. less than ten seconds, electric current is: 80-100mA, year power consumption is less than 100mAh, and the capacity of No. 7 dry cells is generally more than 400 mAh.If connect infrared remote control receiver IRM, the utility model just has the static consumption of less standby.
