Detailed Description
The embodiment of the application provides a method, a device, equipment and a storage medium for detecting a thyristor jumper, and solves the technical problem that whether the thyristor jumper is conducted or not during overvoltage protection and whether the thyristor jumper acts correctly or not can not be detected when the performance of the existing thyristor jumper is detected.
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
A first aspect of an embodiment of the present application provides an embodiment of a method for detecting a thyristor jumper.
Referring to fig. 2, a schematic flow chart of a first embodiment of a method for detecting a thyristor jumper in an embodiment of the present application includes:
step 201, applying a forward overvoltage to a thyristor trigger loop of the thyristor jumper, and collecting a first voltage value of a forward protection thyristor of the thyristor jumper.
It should be noted that, since the thyristor is triggered by the thyristor trigger circuit when the thyristor jumper is subjected to overvoltage protection, overvoltage is applied to the thyristor trigger circuit when the overvoltage is applied. A forward overvoltage is applied to the thyristor trigger loop of the thyristor jumper when detection of the forward overvoltage protection is performed.
The forward overvoltage is used for triggering the forward protection thyristor, so that when the forward overvoltage is applied to the thyristor trigger loop, a first voltage value of the forward protection thyristor is collected, and the first voltage value represents an action signal for executing action of the thyristor jumper during the forward overvoltage protection.
Step 202, applying a reverse overvoltage to the thyristor trigger loop, and collecting a second voltage value of a reverse protection thyristor of the thyristor jumper.
It should be noted that, since the thyristor is triggered by the thyristor trigger circuit when the thyristor jumper is subjected to overvoltage protection, overvoltage is applied to the thyristor trigger circuit when the overvoltage is applied. A reverse overvoltage is applied to the thyristor trigger loop of the thyristor jumper when the detection of the reverse overvoltage protection is performed.
The reverse overvoltage is used for triggering the reverse protection thyristor, so that when the reverse overvoltage is applied to the thyristor trigger loop, a second voltage value of the reverse protection thyristor is collected, and the second voltage value represents an action signal for executing action of the thyristor jumper during reverse overvoltage protection.
And step 203, comparing the first voltage value with the forward overvoltage protection voltage threshold to obtain a first detection result of the action executed by the thyristor jumper when the thyristor jumper performs forward overvoltage protection.
It should be noted that, by comparing the first voltage value with the forward overvoltage protection voltage threshold, a first detection result of the action executed by the thyristor jumper during forward overvoltage protection can be obtained. The specific comparison criteria are: when the difference value between the first voltage value and the forward overvoltage protection voltage threshold value is smaller than the first difference value threshold value, the action is accurately executed. The first difference threshold herein may be set as needed, and is not particularly limited herein.
It is understood that the setting of the forward overvoltage protection voltage threshold can be performed by those skilled in the art according to the needs and the specific application scenarios, and is not limited herein. For example, generators of different voltage classes may set the threshold differently.
And step 204, comparing the second voltage value with the reverse overvoltage protection voltage threshold value to obtain a second detection result of the action executed by the thyristor jumper when the thyristor jumper performs reverse overvoltage protection.
It should be noted that, by comparing the second voltage value with the reverse overvoltage protection voltage threshold, a second detection result of the action executed by the thyristor jumper during the reverse overvoltage protection can be obtained. The specific comparison criteria are: and when the difference value between the second voltage value and the reverse overvoltage protection voltage threshold value is smaller than the second difference value threshold value, the action is accurately executed. The second difference threshold herein may be set according to needs, and is not particularly limited herein.
It is understood that the setting of the reverse overvoltage protection voltage threshold can be performed by those skilled in the art according to the needs and the specific application scenario, and is not limited herein. For example, generators of different voltage classes may set the threshold differently.
When the thyristor jumper is used for overvoltage protection, after a forward overvoltage triggers a forward protection thyristor, a de-excitation loop is triggered, and after a reverse overvoltage triggers a reverse protection thyristor, the de-excitation loop is triggered, so that the forward overvoltage and the reverse overvoltage are respectively applied to the thyristor jumper in the application, then a first voltage value of the forward protection thyristor and a second voltage value of the reverse protection thyristor are correspondingly collected, the first voltage value represents an action signal of the thyristor jumper when the forward overvoltage protection is carried out, the second voltage value represents an action signal of the thyristor jumper when the reverse overvoltage protection is carried out, then the first voltage value and the second voltage value are respectively compared with corresponding overvoltage protection thresholds, namely the detection results of the execution actions of the thyristor jumper when the forward overvoltage protection and the reverse overvoltage protection are carried out are obtained, the technical problem that whether the thyristor jumper is correctly operated or not can not be detected only by detecting whether the thyristor jumper is conducted or not during overvoltage protection when the performance of the existing thyristor jumper is detected is solved.

And 302, conducting test is carried out on the reverse protection thyristor, and then a second conducting result corresponding to the reverse protection thyristor is obtained.
It should be noted that, in order to ensure that the detection result is correct, the conductivity of the reverse protection thyristor is tested in this embodiment.
It can be understood that, after conducting the conduction test on the reverse protection thyristor, obtaining the second conduction result corresponding to the reverse protection thyristor specifically includes:
when a forward trigger signal is applied between the positive circuit and the negative circuit of the reverse protection thyristor, a third breaking signal of a second indicator light connected to the reverse protection thyristor is collected;
when a reverse trigger signal is applied between the positive and negative loops of the reverse protection thyristor, a fourth interruption signal of the second indicator light is collected;
and determining a second conduction result corresponding to the reverse protection thyristor according to the third break signal and the fourth break signal.
Specifically, referring to fig. 4, a forward 6V battery lamp (a second indicator lamp with a power supply, not shown) is applied between the positive and negative loops (BC) of the reverse protection thyristor V2, a forward voltage of 3V is applied to the trigger loop (a02 terminal 2), and the forward 6V battery lamp is applied to the positive and negative primary loops of V2. The forward trigger voltage of 3V is removed and the positively connected 6V battery lamp is still on, indicating that the main circuit is still on. When a reverse voltage is given to the main loop and the same trigger signal is used, the V2 can not be conducted, which indicates that the conduction performance of the reverse protection thyristor V2 is normal.
