And whether the relay coil is normal can be determined by detecting whether the coil test resistance of the relay coil in the loop is within a preset qualified range through the coil.
Fig. 3 is a block diagram illustrating another relay testing apparatus according to an exemplary embodiment, and as shown in fig. 3, the power module 12 includes an access component 121 and a transformation component 122, the access component 121 is connected with the transformation component 122,
the access component 121 is used for connecting an external power supply to access an external power supply;
and the converting component 122 is used for performing voltage conversion on the standby power output by the external power supply to output power of target power supply parameters, so as to form a test power supply, wherein the target power supply parameters comprise a first voltage range or a current range of direct current and a second voltage range of alternating current.
For example, an external power supply may be connected to the access component 121 for supplying power to the test module, and the external power supply may be a 220V or 380V ac power supply, which is not limited by the present disclosure.
The relay to be tested can be divided into a direct current voltage relay, a direct current relay, an alternating current voltage relay and a transformation component 122 according to the action parameter distinction, and the transformation component is used for carrying out voltage transformation on standby power supply output by an external power supply source so as to output power supply of target power supply parameters and supply power for the relay to be tested.

Illustratively, the relay to be tested is a direct current voltage relay, and the converting component is configured to convert the external power supply into an adjustable direct current, wherein the first voltage range of the direct current includes an operating voltage and a release voltage of the direct current voltage relay.

When the target power supply parameter of the relay is larger than or equal to the first target power supply parameter, the normally open contact of the relay to be tested can be changed from being opened to being closed, and the normally closed contact of the relay to be tested can be changed from being closed to being opened. For example, the relay may be a direct current voltage relay, and the normally open contact is changed from open to closed and the normally closed contact is changed from closed to open when the direct current voltage between the relay coils is greater than or equal to the first target power supply parameter. The normally open contact can be determined to be changed from open to closed by measuring the resistance change between the normally open contacts through the normally open contact detection circuit, and the normally closed contact can be determined to be changed from closed to open by measuring the resistance change between the normally closed contacts through the normally closed contact detection circuit. When the direct-current voltage between the relay coils is smaller than a second target power supply parameter, the normally open contact is changed from closed to open, and the open normally closed contact is changed from open to closed. The normally open contact can be determined to be changed to be opened from closed by measuring the resistance change between the normally open contacts through the normally open contact detection loop, the normally closed contact is determined to be changed to be closed from open by measuring the resistance change between the normally closed contacts through the normally closed contact detection loop, and the second target power supply parameter can be smaller than the first target power supply parameter, so that the disclosure does not limit the normally open contact.

and the transformation component 122 is used for supplying power to the coil interface according to the adjusted target power supply parameter.
For example, to measure and determine the first target power supply parameter and the second target power supply parameter, the adjusting component 112 may adjust the target power supply parameter in response to receiving an adjustment instruction of the target power supply parameter from a user, and may gradually adjust and increase the target power supply parameter from a preset initial power supply parameter until the first target power supply parameter is tested or the target power supply parameter is increased to a maximum target power supply parameter. For example, in the case of a dc voltage relay, the rated operating voltage is 6VDC, the initial power supply parameter may be 0VDC, the dc voltage between the coils is gradually increased from 0VDC in the coil detection circuit in response to receiving a user instruction to adjust the dc voltage, and the target operating parameter at the time when it is detected that the normally open contact is changed from open to closed and the normally closed contact is changed from closed to open may be the first target power supply parameter. And determining that the first target power supply parameter is not acquired under the condition that any one of the following conditions is met, wherein the first target power supply parameter can be a preset invalid value when the first target power supply parameter is not acquired.

and 2, only one of two events that the normally open contact is changed from open to closed and the normally closed contact is changed from closed to open is detected, or the time difference of the two events is greater than or equal to a preset time difference threshold value.
Under the condition that the first target working parameter is obtained, the target power supply parameter can be gradually adjusted and reduced until the first target power supply parameter is tested or the preset initial power supply parameter is reduced.
For example, for a dc voltage relay, the rated operating voltage of the dc voltage relay is 6VDC, the target operating parameter may be gradually decreased when the target operating parameter is a first target operating parameter, and when it is detected that the normally open contact is changed from closed to open and the normally closed contact that is opened is changed from open to closed, the target operating parameter at this time may be set as the second target power supply parameter.
And determining that the second target power supply parameter is not acquired under the condition that any one of the following conditions is met, wherein the second target power supply parameter can be a preset invalid value when the second target power supply parameter is not acquired.

the test module is used for determining that the test judgment result of the test parameter is a test pass under the condition that the test parameter is determined to belong to a preset qualified range, and determining that the test judgment result of the test parameter is a test exception under the condition that the test parameter is determined not to belong to the preset qualified range;
the prompt component is used for receiving the test judgment result and outputting preset prompt information according to the test judgment result;
and the numerical value display component is used for displaying the test parameters.
9. The apparatus of claim 8, wherein the prompt component comprises a test pass indicator light and a test exception indicator light;
the test passing indicator lamp is used for lighting under the condition that the test judgment result corresponding to each test parameter of the relay to be tested is pass;
and the test abnormity indicator light is used for lighting under the condition that the test judgment result corresponding to any one of the plurality of test parameters of the relay to be tested is abnormal.
10. The apparatus of claim 8, further comprising an input component;
the input assembly is connected with the test module and used for receiving a parameter setting instruction input by a user, and the parameter setting instruction comprises: at least one of the qualified range, the first preset adjustment granularity and the second preset adjustment granularity corresponding to the test parameter.
