Before secondary circuit debugging, the debugging personnel needs to recheck the line of all secondary lines to improve the accuracy of secondary circuit debugging. But in the case that all secondary circuits have been connected, the normally closed node of the complete circuit (or the normally open node that has been operated) will make several wire cores conductive (the operation mode of many circuits of the substation secondary equipment is based on one common end with multiple circuits), and the current line checking method needs to disassemble the cable wire core from the terminal to realize the line checking work, thus greatly reducing the work efficiency, and repeatedly disassembling and connecting the line will affect the wiring process and the service life of the corresponding terminal row. In addition, in the running substation, the running circuit cannot be disassembled from the terminal for checking, for example, disassembling the current circuit will cause the CT to be open, which has the risk of damaging the equipment and causing electric shock.

[0025] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0026] Figure 1 is a schematic block diagram of the substation safety line checking instrument shown in an exemplary embodiment of the present application, referring to Figure 1 , a substation safety line checking instrument is provided, comprising:

[0027] a line checking master and a line checking slave;

[0028] The line checking master comprises a loop live detection module, a signal transmitting module, a display module, a communication module and a data processing module;

[0029] The line checking slave comprises a loop live detection module, a signal receiving module, a display module, a communication module and a data processing module;

[0030] The loop live detection module detects whether the to-be-checked line in contact with it is live, and displays the live condition on the display module;

[0031] The signal transmitting module transmits a detection signal in the live direction through the to-be-checked line in contact with it, and the signal receiving module receives the detection signal;

[0032] The data processing module of the master and the data processing module of the slave exchange data through the respective communication modules, compare the transmitted detection signal and the received detection signal, and determine whether the directions are consistent.

[0033] In specific practice, when the nuclear line personnel uses the substation safety nuclear line instrument to perform nuclear line, without disassembling the wire, the master and the slave are directly contacted with the to-be-tested wire, as shown in Figure 2 and Figure 3 When the nuclear line personnel wants to test the second wire, the master and the slave are only needed to be connected at the port where the wire should be correctly connected, at this time, the loop live detection module of the master and the loop live detection module of the slave both detect whether the wire is live, and display on the display module, if the to-be-tested wire is live, live is displayed on the display module, if the to-be-tested wire is not live, live is not displayed. The range that the live detection function can detect is generally 0-380V of the secondary loop alternating voltage and -110-+110V of the direct current voltage. The loop live detection module is equivalent to a multimeter.

[0034] After connection, the signal transmitting module transmits the direction detection signal along the test wire, the detection signal is a non-electric signal with direction, because the running loop is encountered in the substation operation, it is suggested to use a non-electric signal, but needs to have direction. The signal receiving module of the slave receives the detection signal, the communication module of the master and the communication module of the slave establish communication connection, the data processing module uses the established communication connection to exchange data, so that the master and the slave compare the transmitted detection signal and the received detection signal, analyze whether the directions of the transmitted detection signal and the received detection signal are consistent, if the transmitted detection signal is forward, if the received detection signal is consistent with the received detection signal, the direction of the received detection signal is also forward, indicating that the cable where the master and the slave are located is the same cable, then the same cable is displayed on the display module, so that the nuclear line personnel can view. If the received detection signal is not consistent with the received detection signal, the direction of the received detection signal is reverse, then no display is displayed on the display module.

[0035] Preferably, the display module can be a plurality of indicator lights set, when the loop live detection module detects that the to-be-tested wire is live, the corresponding indicator light is lit, when the data processing module judges that the directions of the transmitted detection signal and the received detection signal are both forward, the corresponding indicator light is lit. The display module can be a display screen, the display screen can display the voltage data measured by the loop live detection module and the judgment result of the data processing module.

[0036] It can be understood that the substation safety line checking instrument provided in the embodiment includes a line checking master and a line checking slave, the master and the slave detect whether the to-be-checked line in contact with the master and the slave is live through respective loop live detection modules, and display the live condition on a display module; the master sends a detection signal with a direction through a signal transmitting module, and a signal receiving module of the slave receives the detection signal; a data processing module of the master and a data processing module of the slave exchange data through respective communication modules, compare the sent detection signal and the received detection signal, determine whether the directions are consistent, and if so, display through the display module. It can be understood that the technical solution provided in the embodiment does not need to disconnect the line, but only needs to check the line by contacting the master and the slave with the to-be-checked line, thereby improving the working efficiency and safety of line checking.

[0037] It should be noted that in the substation safety line checking instrument, the line checking master further includes a power module, and the power module is configured to supply power to the line checking master; the line checking slave further includes a power module, and the power module is configured to supply power to the line checking slave.

[0038] In specific implementation, the power module can be a battery, and the power module can supply power to other modules of the line checking master or the line checking slave, so that the line checking master and the line checking slave do not need to be connected to other power sources when being used, which facilitates the line checking personnel to use and improves the line checking efficiency.

[0039] It should be noted that in the substation safety line checking instrument, the line checking master further includes an operation button, and when the operation button is pressed, the signal transmitting module sends a detection signal with a direction.

[0040] In specific implementation, after the line checking personnel connect the line checking master, a certain time is needed to set the line checking slave, and after the line checking master and the line checking slave are both connected to the to-be-checked line, the operation button on the line checking master can be pressed to make the line checking master send a detection signal with a direction. It can be understood that the operation button can make the line checking master reduce sending of invalid signals, improve the service life of the line checking master, and the timing of sending the signal is controlled by the line checking personnel, so that whether the line connected to the master and the slave is the same line can be more accurately determined.

[0041] It should be noted that in the substation safety line checking instrument, the communication module is a kilometer-level wireless communication module.

[0042] In the actual practice, when the substation is actually checked, the test device and the monitored equipment can be far away from each other, if the communication distance of the communication module is short, the communication connection can be disconnected, and the data interaction between the data processing modules can be affected, and the checking result can be affected. Therefore, the communication module needs to select a long-distance communication module, preferably a kilometer-level wireless communication module, to ensure that the communication connection between the checking host and the checking slave can be maintained effectively when the checking personnel are checking.

[0043] It should be noted that the substation safety checking instrument, the checking host further comprises a test port, the checking slave further comprises a test port, and the test port is used for contacting the to-be-checked.

[0044] In the actual practice, by arranging the test ports on the checking host and the checking slave, the host and the slave can be contacted with the to-be-checked, and the detection abnormality caused by the poor contact between the host or the slave and the to-be-checked due to the unskilled operation of the checking personnel can be reduced.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
