Make, completely by operator's eye recognition, but whether qualification cannot clearly embody test product during action, and especially multiple test products are closing
When lattice actuation time nearby acts, whether operator can not take into account, it is impossible to clearly judge which test product within qualified actuation time
Action, causes result of the test mistake.
The content of the invention
The utility model provides one kind for technical problem present in solution known technology result of the test to be made to show automatically
The electrothermal relay Characteristics Detection test product action display device shown.
The utility model is adopted the technical scheme that solve technical problem present in known technology：It includes
It is 220 volts of AC voltage regulators, the multiple resistance identical with multiple electrothermal relay numbers to be detected, identical with the multiple resistance number
Multipair red and green luminous diode, a time relay, a button and 24 volts of DC power supplies；The AC voltage adjusting
The output terminal of device connects the two end terminals after the multiple electrothermal relay series connection to be detected respectively；The both ends of 24 volts of DC power supplies
The both ends after the button and time relay series connection are connect respectively；One end of each resistance in the multiple resistance and institute
The anode for stating 24 volts of DC power supplies is connected, and the other end normally opened contact in parallel with the one pair of which of the time relay and
One end of normally-closed contact is connected, the other end of the pair of normally opened contact in parallel and normally-closed contact respectively with it is described multipair red
The Red LED1 in the red and green luminous diode of a pair in green light emitting diode is connected with one end of green light emitting diode, institute
State Red LED1 and green light emitting diode the other end be connected with each other after, then in the multiple electrothermal relay to be detected of connecting
An electrothermal relay to be detected two leading-out terminals of normally opened contact after be connected with the cathode of 24 volts of DC power supplies.
The utility model has the advantages and positive effects of：Testing result technical solution is shown as a result of automatic,
For operator by acting the color of display lamp, it is to act within qualified time or in addition that can clearly judge test product, is arranged
When being acted simultaneously except more test products, the mistake that artificially judges.Not only display device structure is simple, easy to use, also ties experiment
Fruit is very clear.
Description of the drawings
Fig. 1 is the electrothermal relay Characteristics Detection test product main circuit diagram of the utility model；
Fig. 2 is the schematic diagram of device of the utility model；
Fig. 3 is the control flow chart of the utility model.
Specific embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing：
As shown in Figure 1,220V exchange electrical connection pressure regulator T1 input sides, the heat that the connection of pressure regulator T1 outlet sides is serially connected
Relay characteristic detects test product 1,2,3,4,1. 2. 3. 4. 5. 6. 7. 8. terminal is respectively that the normally opened contact of test product 1,2,3,4 is drawn
Terminal.
As shown in Fig. 2,
24V positive poles connection button SB1 one sides, one end of button SB1 opposite side Connection Time relay KT, the time after
Electric appliance KT other ends connection 24V power supplys.
24V power supplys connection resistance R1 one sides, the normally opened contact of resistance R1 opposite sides connection time relay KT in parallel and
Normally-closed contact, normally opened contact opposite side connecting luminous diode D1, normally-closed contact opposite side connecting luminous diode D2, luminous two
After the pole pipe D1 other end connecting luminous diode D2 other ends with terminal 1., 24V power supplys are connected after 2. terminal concatenates.Other are several
Road is also connected according to above-mentioned connection, and in Fig. 1 and 2,1. 2. 3. 4. 5. 6. 7. 8. terminal represents same terminal.This UV light-emitting diode
D1, D3, D5, D7 are red diode, and light emitting diode D2, D4, D6, D8 are green diode.
The requirement of time relay KT setting times is test product qualified actuation time, starts to test by lower button SB1, the time after
Electric appliance KT starts timing, by taking test product 1 as an example：When test product 1 acts within qualified actuation time, 1. 2. terminal is connected, time relay
Device KT contacts not yet act, and light emitting diode D2 is bright, and light emitting diode D1 goes out, and operator sees green instruction, represent that test product 1 closes
Lattice.When test product 1 acts outside qualified actuation time, 1. 2. terminal is connected, and time relay KT contacts have acted, light-emitting diodes
Pipe D1 is bright, and light emitting diode D2 goes out, and operator sees red instruction, represents that test product 1 is unqualified.
As shown in figure 3,
Specific workflow is as follows：
1. pressing start button SB1, step 2 is performed；
2. time relay KT starts timing, step 3 is performed；
3. waiting test product action, step 4 is performed；
4. if action, time relay KT are not attracted in qualified time, light emitting diode D2 is bright, and result is qualification；If
It is acted outside qualified time, then time relay KT is attracted, and light emitting diode D1 is bright, and result is unqualified.
