Reason figure（Fig. 2 to Fig. 4）Line is carried out, each electric elements is connected.
Equipment each several part operation principle and flow is described in detail in Fig. 2 to Fig. 5.
Circuit diagram is unidirectionally continuously run as shown in Fig. 2 the figure is motor, the circuit course of work is as follows：
Examinee carries out wiring according to circuit theory diagrams.Inching button 2SB3 is pressed after the completion of wiring, contactor KM3 coils are obtained
Electricity, motor Positive work unclamps 2SB3, and motor shuts down immediately.When there is electromotor overload, main circuit current increases
Greatly, the thermal element for the electrothermal relay 2KH being at this moment connected in main circuit will be jumped because the heat of the excessive generation of electric current is excessive
Lock, disconnects the 2KH in control circuit, contactor KM3 coil losing electricities, motor is out of service.Electrothermal relay 2KH is to overload
Protection, fuse 2FU1 is to make short-circuit protection, when short circuit occurs for circuit, will make fuse blows because electric current is excessive, from
And protect electric equipment.Stop button is 2SB2, and motor stops when pressing it, and scram button 2SB1 is in case of emergency pressed,
Circuitry is powered off, motor stall.
As shown in figure 3, the figure is motor positive/reverse rotation circuit figure, it is the motor using button and contactor double interlock
The control circuit of positive and negative two directions operation.Circuit operation principle is as follows：
First, it is positive to start：
1. examinee carries out wiring according to circuit theory diagrams, after the completion of wiring, air switch 1QF1 and 1QF2 are closed, electricity is connected
Source；
2. pressing positive start button 1SB3, KM1 energizations adhesive and self-locking, main contact closure connect motor, motor
At this moment phase sequence is 1L1,1L2,1L3, i.e., positive operation.
2nd, reverse starting：
1. examinee carries out wiring according to circuit theory diagrams, after the completion of wiring, air switch 1QF1 and 1QF2 are closed, electricity is connected
Source；
2. pressing reverse starting button 2SB4, KM2, which is powered, inhales merga pass auxiliary contact self-locking, normally opened main contact closure,
The changing-over power phase of motor three-phase, at this moment the phase sequence of motor is L3, L2, L1, i.e. inverted running.
3rd, link is interlocked：Play safeguard protection in the line with prohibiting function
1. contactor interlocking：KM1 wire loops seal in KM2 normally closed auxiliary contact, and KM2 wire loops seal in the normal of KM1
Closed contact.After positive contactor KM1 coil electricities are acted, KM1 auxiliary normally-closed contact is disconnected KM2 wire loops, if making
KM1 obtains electric adhesive, it is necessary to first make KM2 power-off releases, it aids in normally closed interlock to reset, This prevents KM1, KM2 adhesive simultaneously
Phase fault is caused, this line link is referred to as interlocking link；
2. press interlock：The positive and reverse rotation control circuit of control button operation is employed in circuit, and button SB2, SB3 have
There are a pair of normally opened contacts, a pair of normally-closed contacts, the two contacts are connected with KM1, KM2 wire loop respectively.Such as button SB2's
Normally opened contact is connected with contactor KM2 coils, and normally-closed contact is connected with contactor KM1 wire loops.The normally opened of button SB3 touches
Point is connected with contactor KM1 coils, and normally-closed contact pressure KM2 wire loop series connection.Can only so there is contactor when pressing SB2
KM2 coil can be powered and KM1 is powered off, and the coil that can only have contactor KM1 when pressing SB3 can be powered and KM2 is powered off, such as
Fruit presses SB2 and SB3 simultaneously, and then two contactor coils can not all be powered.Thus serve the effect of interlocking.
4th, motor is positive（Or reversely）Start after operating, it is not necessary to first stop motor by stop button, can be direct
By reverse（Or it is positive）Start button, makes motor be changed into reverse direction operation.
5th, the overload protection of motor is completed by electrothermal relay 1KH.
As shown in figure 4, the figure is single-phase watt-hour meter circuit diagram, circuit operation principle is as follows：
Examinee carries out wiring according to circuit theory diagrams, and rocker switch can be pressed after the completion of wiring and carries out energization test, such as
The correct fluorescent lamp of fruit wiring can be lighted, and otherwise will not be lighted.The operation principle of kilowatt-hour meter is as follows：When ammeter accesses circuit-under-test
Afterwards, circuit-under-test voltage is added on potential winding, after circuit-under-test electric current is by current coil, is produced two alternating fluxes and is passed through
Aluminium dish, the two magnetic fluxs are identical in time, produce vortex in aluminium dish respectively.Due to magnetic flux be vortexed interaction and produce
Raw rotating torque, rotates aluminium dish.The magnetic flux of brake magnet, also through aluminium dish, when aluminium dish is rotated, cuts this magnetic flux, in aluminium
Electric current is induced on disk, the magnetic flux of this electric current and brake magnet interacts and produces a system opposite with aluminium dish direction of rotation
Kinetic moment, makes the rotating speed of aluminium dish reach uniformly.
As shown in figure 5, the examination flow of this equipment is：The first step, examinee, which swipes the card, starts examination；Second step, examinee according to
Topic carries out wiring；Examinee's operation button checks whether indicator lamp is working properly after the completion of 3rd step, wiring, and such as motor is rotated forward and pressed
Button, sees whether rotating forward indicator lamp is lighted, and determines whether wiring is correct with this, and such as wiring is incorrect, it is necessary to rewiring.4th
Step, examinee clicks on submitting button before the test time is finished, and system proceeds by the wiring condition of automatic detection examinee, detection
Time is general within 10 seconds, to achieving the result after the completion of detection, passes back to examination management center.
