Background technology
At present to the equipment of electrothermal relay Characteristics Detection, lighted by single indicator lamp so as to show that test product moves
Make, completely by operator's eye recognition, but whether test product is qualified during action clearly to embody, 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
Technical problem present in present invention solution known technology and providing a kind of makes result of the test show automatically
Electrothermal relay Characteristics Detection test product acts display device and control method.
The present invention shows dress to solve electrothermal relay Characteristics Detection test product action in technical problem present in known technology
Put and adopted the technical scheme that：It includes 220 volts of AC voltage regulators and multiple electrothermal relay number identicals to be detected are more
Individual resistance and the same number of multipair red and green luminous diode of the multiple resistance, a time relay, a button and one
Individual 24 volts of dc sources；After the output end of described AC voltage regulator connects the multiple series connection by electrothermal relay to be detected respectively
Two end terminals；The both ends of 24 volts of dc sources connect the both ends after the button and time relay series connection respectively；Institute
The one end for stating each resistance in multiple resistance is connected with the positive pole of 24 volts of dc sources, and the other end and the time after
The one pair of which of electrical equipment normally opened contact in parallel is connected with one end of normally-closed contact, the pair of normally opened contact in parallel and
The other end of normally-closed contact respectively with the Red LED1 in the pair of red and green luminous diode and green light emitting diode
One end is connected.After the other end of the Red LED1 and green light emitting diode is connected with each other, then connect the multiple to be checked
After two leading-out terminals of normally opened contact of an electrothermal relay to be detected in calorimetric relay with 24 volts of dc sources
Negative pole is connected.
The present invention shows dress to solve electrothermal relay Characteristics Detection test product action in technical problem present in known technology
The control method put is adopted the technical scheme that：
Its rate-determining steps is：
1) presses start button SB1, performs step 2；；
2) time relays KT starts timing, performs step 3；
3) waits test product action, performs step 4；
If 4) acted in qualified times, the non-adhesives of KT, D2 is bright, as a result to be qualified；If acted outside qualified time, KT
Adhesive, D1 is bright, as a result to be unqualified.
The present invention has the advantages and positive effects of：As a result of automatic display testing result technical scheme, operation
For person by acting the color of display lamp, it is to act within qualified time or in addition that can clearly judge test product, is eliminated
More test products act simultaneously when, the mistake that artificially judges.Not only display device structure is simple, easy to use, also makes result of the test one
Mesh is clear.
Brief description of the drawings
Fig. 1 is the electrothermal relay Characteristics Detection test product main circuit diagram of the present invention；
Fig. 2 is the schematic diagram of device of the present invention；
Fig. 3 is the control flow chart of the present invention.
Embodiment
For present disclosure, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing detailed
It is described as follows：
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 sources connection button SB1 sides, button SB1 opposite side Connection Time relay KT one end, the time after
Electrical equipment KT other ends connection 24V power supplys.
24V power supplys connection resistance R1 sides, resistance R1 opposite sides connection time relay KT in parallel normally opened contact 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 also connects 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 time relay KT setting times requirement be test product qualified actuation time, press button SB1 and start to test, the time after
Electrical equipment 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 diode
