It is connected to general supply end through general supply control switch K, secondary is connected to current rectifying and wave filtering circuit, power supply indicator FD1Through current-limiting resistance R1Afterwards
It is connected across the output end of Transformer Rectifier filter circuit.
After closing general supply control switch K, transformer B is powered on, and the low AC voltage of B grade output is through diode
D1-D4 rectification, capacitor C6After filtering to the present invention provide DC supply, total loop general supply end without cross, under-voltage therefore
Voltage detector IC in the case where barrier, for low-voltage protection11st input pin voltage is higher than IC1Conversion voltage, IC12nd
Output pin is high level, NAND gate IC3b6th foot is also high level, the voltage detector IC for overvoltage protection21st input
Foot voltage is lower than IC2Conversion voltage, IC22nd output pin is low-voltage, and NAND gate IC3a the 8th, the 9th input pin are low level,
10th output pin is high level, IC3b5th input pin is also high level, and the 4th output pin is low level, NAND gate IC3c the 1st, the 2nd
Input pin is all low level, and the 3rd output pin is high level, this high level is through resistance R10To capacitor C3Charging, then through resistance R11It is right
Capacitor C4Charging, with C3、C4The rising of upper end voltage, triode V2 Delayed conducting, relay J1It is powered and is attracted, J1Two groups of touchings
Point J1-1And J1-2Conversion, J1-1Normally opened contact closure, capacitor C3Through resistance R12Repid discharge makes triode for charging next time
V2Delayed conducting is ready, J1-2Normally opened contact closure, the second relay J2Closure is converted to because adding positive arteries and veins charging voltage
State, J2Two groups of contact J2-1And J2-2Closed state is converted to by off-state, it will before J2 does not add negative pulse voltage
It is always maintained at this closed state, the general supply end of total loop and total load termination are logical, and the output of NAND gate IC3c the 3rd is high voltage
When, the 11st output pin of IC3d is low level, triode V1In off state.After closing general supply control switch K, first
Do not touching 1AN1Trigger controllable 1T1Before conducting, relay 1J1It is not turned on actuation, normally closed touching 1J1-1Keep magnetic
Relay 1J2In addition positive pulse voltage, 1J2Normally opened contact 1J2-1First branch load end and total load are terminated and are led to by closure,
After total load end and general supply termination are logical, first branch load is initially powered up operation, other each branches and the first branch
Working principle is identical.
Specific circuit operation principle is as follows:
The protection of overvoltage under-voltage self-recovering type: when closing general supply control switch K, if total loop existed, under-voltage
Failure, the present invention give refusal to total load end combined floodgate power transmission, and after total negative terminal connects the operation of general supply end, total loop occurred,
Under-voltage failure, the present invention will cut off the power supply at total load end immediately, to guarantee the electrical equipment at total load end not because of voltage mistake
Low or excessively high and damage, to keep away negative because of mistake, electrical safety accident and electrical fire accident caused by under-voltage failure are returned when total
After road voltage restores normal, the present invention, which automatically will terminate total load end and general supply in 15S, leads to, to ensure normal electricity consumption,
Its working principle is that: when general supply end brownout, transformer B secondary voltage is also too low therewith, through D1-D4.C6Rectifying and wave-filtering
Voltage afterwards is also and then too low, voltage detector IC1The voltage of 1st input pin is equally and then too low, works as IC11st input pin voltage
Lower than IC1Conversion voltage when, IC12nd output pin becomes low level from high level, and under-voltage fault indicator light FD2 energization brightens,
The 4th output pin of NAND gate IC3b becomes high level from low level, and the 3rd output pin of IC3c becomes low level, IC3d from high level
11 output pins become high level, first triode V from low level1Conducting, flashing diode FD6 energization flashing light alarm of alarming,
Buzzer Y, which is also powered, issues alarm, before the 3rd output pin of IC3c becomes low level, if second triode V2 is also not
Conducting, total load end also access failure general supply end, then make V2It is continually maintained in and cuts upper state, if V2 is in the conductive state,
Total load end has been turned on general supply end, then makes V2Become cutting upper state, the first relay J from state1Power-off release, J1's
Two groups of contact J1-1And J1-2Conversion, J1-1Normally-closed contact closure, by delay capacitor C3Pass through resistance R11Access V2Base report, J1-2's
Normally-closed contact closure, capacitor C5It discharges to the second relay J2, J2 is because adding negative pulse voltage due to transition status, J2Two groups of touchings
Point J2-1And J2-2Off-state is converted to by closed state, the present invention cuts off general supply end and total load end, according to practical need
It determines that under-voltage acts setting value, reasonably selects the resistance value of resistance R2, R4 further according to under-voltage movement setting value and voltage is examined
Survey device IC1Conversion voltage value, when general supply end, voltage rises to recovery value, the output valve of Transformer Rectifier filter circuit also with
