Preferably, described control circuit 15 also comprises: light emitting diode, connects with described starting switch.Described light emitting diode can be traction pilot lamp 8 and the brake indicator lamp 9 of described two positions switch test unit.Described traction pilot lamp 8 and brake indicator lamp 9 inlay assigned address in the chassis by described control circuit.By this, staff is by observing the luminous operation known two positions switch test unit and carry out two positions switch of which pilot lamp.
Wherein, described two positions switch test unit can provide experiment power supply for the multiple electrical equipment in two positions switch, electric control contactor, electromagnetic contactor, auxiliary reclay, the time relay and electric pneumatic valve.
Fig. 1 is the circuit diagram of the two positions switch test unit that the utility model provides.As shown in Figure 1, plate glass insurance pipe FU1 connects with power switch K1, and plate glass insurance pipe FU1 and power switch K1 is in parallel with A.C. voltmeter 1.When circuit ON 220V AC power, the reading on A.C. voltmeter 1 can be clear that.A.C. voltmeter 1 is in parallel with autotransformer 13, and rectifier bridge is in parallel with autotransformer 13.Wherein, rectifier bridge is composed in series by commutation diode D1, D2, D3, D4, for alternating current is transformed into direct current.Rectifier bridge is connected with plate glass insurance pipe FU2, and rectifier bridge and plate glass insurance pipe FU2 in parallel with D.C. voltmeter 2.The size of DC voltage can be regulated by the contact a between slip commutation diode D1 and commutation diode D3.Certainly, the reading of D.C. voltmeter 2 also can along with change.
Starting switch SK1, starting switch SK2 connect with time relay T1, and D.C. voltmeter 2 is in parallel with them.The Chang Kailian of time relay KT2 locks T2, the normally closed interlocking S2 of auxiliary reclay KM2 connects with auxiliary reclay KM1.Starting switch SK1, starting switch SK2 and time relay KT1 and the Chang Kailian of time relay KT2 lock T2, auxiliary reclay KM2 the normally closed S2 and auxiliary reclay KM1 that interlocks in parallel.The Chang Kailian of time relay KT1 locks T1, the normally closed interlocking S1 of auxiliary reclay KM1 connects with auxiliary reclay KM2.Time relay KT2 is in parallel with auxiliary reclay KM2.It is in parallel that starting switch SK3 and the Chang Kailian of auxiliary reclay KM1 lock M1, and they are connected with traction pilot lamp EL1.Lock between M1 and traction pilot lamp EL1 at the Chang Kailian of auxiliary reclay KM1 and draw traction signal line 11.It is in parallel that starting switch SK4 and the Chang Kailian of auxiliary reclay KM2 lock M2, and they are connected with brake indicator lamp EL2.Lock between M2 and traction pilot lamp EL2 at the Chang Kailian of auxiliary reclay KM2 and draw brake signal line 12.
When two positions switch needs to test, first staff will connect air source apparatus, by pressure regulator valve, blast is adjusted to required blast.Then, the attaching plug of two positions switch test unit is inserted on the power supply of alternating current 220V by staff, and on traction electric pneumatic valve traction signal line 11 being received two positions switch and brake signal line 12 receive on the braking electric pneumatic valve of two positions switch.
If staff will carry out independent manual operation according to the requirement provided to two positions switch, staff can press power switch 7, and whether the reading observing A.C. voltmeter 1 is normal, and needs adjustment adjusting pressuring knob 10 according to what test.Then, staff presses traction starting switch 5, just can carry out draw operations to two positions switch, or press man enable switch 6, just can carry out brake operating to two positions switch.
If staff will carry out automatic operation to two positions switch, staff can press and always stop starting switch 3, and two positions switch stops action, and presses automatic start switch 4.So auxiliary reclay KM1 and time relay KT1 obtains electric adhesive, then the Chang Kailian lock M1 by auxiliary reclay KM1 exports a traction signal, just can carry out draw operations to two positions switch.Automatic start switch 4 is reset starting switch, when starting switch is pressed, and closing of circuit.When not according to starting switch, circuit disconnects.After pressing automatic start switch 4, auxiliary reclay KM1 dead electricity discharges, and Chang Kailian locks M1 and disconnects, and time relay KT1 dead electricity time delay 3S discharges.The normally closed interlocking S1 that direct supply locks T1 and auxiliary reclay KM1 by the Chang Kailian of time relay KT1 time delay 3S makes auxiliary reclay KM2 and time relay KT2 obtain electric, Chang Kailian lock M2 then by auxiliary reclay KM2 exports a brake signal, just can carry out brake operating to two positions switch.Time delay is after 3 seconds, and the Chang Kailian of time relay KT1 locks T1 and disconnects, and auxiliary reclay KM2 dead electricity discharges, and Chang Kailian locks M2 and disconnects, and time relay KT2 dead electricity time delay 3S discharges.The normally closed interlocking S2 that direct supply locks T2 and auxiliary reclay KM2 by the time relay KT2 time delay Chang Kailian of 3 seconds makes auxiliary reclay KM1 and time relay KT1 obtain electric, lock M1 by the Chang Kailian of auxiliary reclay KM1 and export a traction signal, just can carry out draw operations to two positions switch.So form automatic reciprocating do action by the time delay of the time relay and the locking contact interlocking of auxiliary reclay.
In the process of test, by the rotation situation observing two positions switch, staff judges whether two positions switch exists the phenomenon of clamping stagnation.Whether there is clamping stagnation by two positions switch can draw, the electric pneumatic valve of two positions switch enter air draft situation.This is because the electric pneumatic valve of two positions switch promotes two positions switch by piston to carry out action.In addition, staff judges the sealing situation after the long-time air feed of transmission reservoir by giving transmission reservoir brush suds.
After off-test, staff answers powered-down switch 7, and the adjusting pressuring knob 10 of autotransformer is recalled to zero-bit, and can carry out the abrasion situation of fingertip and contact, osculatory and contact inspection to two positions switch after closing air source apparatus.
