[0055] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application and how the technical solutions in the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0056] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0057] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0058] A relay protector is a protective device used in an electric power system, and mainly includes components such as a measuring unit, a comparing unit, a logic unit, and an output unit. The logic unit presets the action logic of each protection action, and the action logic includes an electrical signal related to electrical parameters. Different action logics determine different electrical signals. The output unit includes a plurality of outlet pressure plates arranged on the relay protector, and each outlet pressure plate is electrically connected to the electrical signal. The relay protector triggers the corresponding electrical signal according to the set action logic, and causes the outlet pressure plate corresponding to the electrical signal to close after receiving the signal, thereby executing the corresponding protection action. Therefore, the correct action logic is the key to triggering the protection action.

[0059] In the related art, when verifying the action logic of different protection actions, the potential of each outlet pressure plate corresponding to the protection action is generally measured one by one by a handheld multimeter. If there is electricity, it means that the outlet pressure plates are all closed, that is, the protection action is effective, and the action logic verification is passed. However, when using a multimeter for verification, only one outlet pressure plate can be verified at a time, resulting in low verification efficiency.

[0060] Based on this, the present application provides a verification device for a relay protector. The verification device includes a box body, a control module and a plurality of display components; by setting a box body, a controller is set in the accommodating cavity of the box body, and a converter, a communication interface and a plurality of display components are set on the box body, and the converter and the display components are electrically connected to the controller. Among them, the communication interface is used to be electrically connected to the signal port of the relay protector to collect the protection action of the relay protector, and the communication interface is electrically connected to the converter, and the converter is used to convert the electrical signal of the protection action, and each display component is set in a one-to-one correspondence with each outlet pressure plate. In this way, the device establishes a communication connection with the relay protector, and by converting the electrical signal of the current protection action, if it is consistent with the preset electrical signal, the controller controls the display component corresponding to the electrical signal to turn on. Therefore, by observing the opening state of the display component set corresponding to the outlet pressure plate, it can be inferred whether the outlet pressure plate corresponding to the electrical signal is closed, thereby avoiding the need to manually measure the potential on the outlet pressure plate one by one, so as to improve the verification efficiency.

[0061] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0062] like Figures 1 to 5 As shown, an embodiment of the present application provides a verification device for a relay protector 900, including a box 100, a control module 800 and a plurality of display elements 200; the box 100 includes a box body 110, and the box body 110 has a receiving cavity.

[0063] The control module 800 includes a converter 810, a communication interface 820 and a controller 830. The controller 830 is arranged in the accommodating cavity, and the communication interface 820 is arranged on the box body 110. The communication interface 820 is used to be electrically connected to the signal port of the relay protector 900 to collect the protection action of the relay protector 900, and the communication interface 820 is electrically connected to the converter 810, and the converter 810 is used to convert the electrical signal of the protection action.

[0064] The display elements 200 are arranged at intervals on the box body 110 and are arranged one-to-one corresponding to the outlet pressure plates of the relay protection device. The display elements 200 and the converter 810 are electrically connected to the controller 830 .

[0065] The controller 830 is configured to control each display element 200 corresponding to the electrical signal to turn on to display the verification result when the electrical signal is consistent with the preset electrical signal.

[0066] The box body 110 can be processed by an integrated molding method, and the box body 110 can be made of materials such as aluminum alloy, so that the box body 110 has good strength, thereby better protecting the various components in the box body 110; it also has a lightweight effect, which is convenient for the calibration personnel to carry the device to the calibration site with less effort.

[0067] In this application, if Figures 1 to 3 As shown, exemplarily, the box body 110 has a accommodating cavity, in which a controller 830 and a converter 810 are arranged, the box body 110 has a front panel 111 and a rear panel 112, a plurality of display elements 200 are arranged at intervals on the front panel 111, and a communication interface 820 is provided on the rear panel 112; wherein each display element 200 is arranged in one-to-one correspondence with the outlet pressure plate of the relay protector 900, the converter 810 and each display element 200 are electrically connected to the controller 830, the communication interface 820 is electrically connected to the signal port of the relay protector, and the communication interface 820 is also electrically connected to the converter 810.

[0068] Exemplarily, the converter 810 and the controller 830 can be electrically connected through an integrated circuit, etc., each display element 200 and the controller 830, the communication interface 820 and the converter 810 can be electrically connected through wires, etc., and the communication interface 820 and the signal port of the relay protection device can be electrically connected through a signal line such as a network cable. It should be noted that the electrical connection method of each device is only given as an example, and the embodiment of the present application does not impose too many restrictions on this, and it is sufficient to ensure that each device can be electrically connected and started normally.

[0069] During specific use, the communication interface 820 of the controller 830 is electrically connected to the signal port of the relay protector. The signal port is used to output the protection action currently performed by the relay protector. The communication interface 820 is used to collect the protection action and feed it back to the converter 810.

[0070] The converter 810 may be a signal converter for converting the currently executed protection action into an electrical signal as the electrical signal to be verified. Meanwhile, the converter 810 feeds the electrical signal to be verified back to the controller 830 .

[0071] The controller 830 can be an editable logic controller, etc., that is, a preset electrical signal corresponding to the protection action is written into the controller 830, and the above preset electrical signal is used as the standard electrical signal. It can be understood that the standard electrical signal refers to the correct electrical signal that can trigger the protection action, that is, the correct electrical signal can close all the outlet pressure plates corresponding to the protection action.

[0072] In this way, the controller 830 compares the electrical signal to be verified with the standard electrical signal. If the comparison is consistent, it means that the correct protection action can be triggered. If it is inconsistent, it means that the correct protection action cannot be triggered.

[0073] It should be noted that the above-mentioned electrical signal refers to the setting conditions in the relay protector that the current protection action depends on, that is, specific parameters such as current, voltage or control time. Different protection actions have different action logics, that is, the specific electrical signal parameters are different. Because the electrical signal parameters correspond one-to-one to the functions of the outlet pressure plate, different action logics determine different outlet pressure plate combinations. In this application, the display element corresponds one-to-one to the outlet pressure plate, so different action logics determine different display element combinations.

[0074] For example, when a standard electrical signal is executed on the relay protection device 900, the outlet pressure plate a, the outlet pressure plate b and the outlet pressure plate c must be closed; in the present application, the display element and the outlet pressure plate are set one by one, and when the electrical signal to be verified is consistent with the standard electrical signal, the controller 830 controls the display element a, the display element b and the display element c to open normally, which indicates that the outlet pressure plate a, the outlet pressure plate b and the outlet pressure plate c can also be closed normally, thereby indicating that the electrical signal to be verified is correct and the protection action can take effect.

[0075] In this way, the device establishes a communication connection with the relay protection device, which not only simplifies the electrical connection method, but also makes it convenient for the inspection personnel to infer whether the outlet pressure plate corresponding to the electrical signal is closed by observing the open state of the display component set corresponding to the outlet pressure plate, thereby avoiding manual measurement of the potential on the outlet pressure plate one by one, thereby improving the inspection efficiency.

[0076] It should be noted that after the display unit 200 is turned on, the display form of the verification result can be characters or light indications, etc., which can be set according to actual usage requirements. The embodiment of the present application does not impose too many restrictions on this, as long as the verification results have distinguishing indications and are easy for the verification personnel to observe clearly.

[0077] In some embodiments, the display element 200 includes a connection channel 230 and a prompter 210 electrically connected to the connection channel 230 , and the connection channel 230 is electrically connected to the controller 830 .

[0078] In the present application, the display element 200 includes a connection channel 230 and a prompter 210, wherein the connection channel 230 can be a wire or a connector, etc., and the embodiment of the present application is not limited to this, as long as it can be ensured that the prompter 210 is electrically connected to the controller 830 through the connection channel 230.

[0079] It can be understood that the outlet pressure plate, the connection channel 230 and the prompter 210 are set in a one-to-one correspondence. In actual use, when the communication interface 820 is electrically connected to the relay protection device, the controller 830 compares the electric signal to be checked with the standard electric signal, that is, after checking the current action logic, the control connection channel 230 is opened so that the prompter 210 displays the verification result of the corresponding electric signal. Exemplarily, the chip of the controller 830 is provided with a program language for displaying the verification result, which is converted into recognizable symbols or texts by the prompter to indicate the verification result of the electric signal. For example, when the electric signal to be checked is consistent with the standard electric signal, the verification is passed, and the prompter 210 corresponding to the electric signal has a prompt. For another example, when the electric signal to be checked is inconsistent with the standard electric signal, the verification fails, and the prompter 210 corresponding to the electric signal does not indicate, it means that the electric signal is wrong, and similarly, the outlet pressure plate cannot be closed. In this way, the verification result of the electrical signal is displayed in real time, so that the verification result can be output intuitively, so that the verification personnel can judge the closing status of the corresponding outlet pressure plate by judging the information on the prompter 210, thereby avoiding manual measurement of the potential on each outlet pressure plate one by one.

[0080] It should be noted that the display mode of the prompter is related to the signal output mode set in the controller 830. The embodiment of the present application does not impose too many restrictions on this, as long as it is ensured that the controller 830 has a differentiated display of the verification results of the action logic.

[0081] In some embodiments, the indicator 210 includes a display light 211 , and the display light 211 is disposed on the box body 110 .

[0082] In this application, if Figure 1 As shown, illustratively, a display light 211 is provided on the front panel 111 of the box body 110, and the display light 211 is used to display the verification result of the electric signal. Different colors of the display light 211 represent different verification results. For example, if the electric signal to be verified is consistent with the standard electric signal, that is, when the verification is passed, the display light 211 corresponding to the electric signal is green. For another example, if the electric signal to be verified is inconsistent with the standard electric signal, that is, when the verification fails, the display light 211 corresponding to the electric signal is off or red.

[0083] It should be noted that the display mode of the display light 211 is only given as an example and can be set according to actual usage requirements, as long as the verification result is displayed clearly and obviously.

[0084] In this way, by providing the display light 211, the verification result of the electrical signal is displayed by a striking light color, so that the verification personnel can quickly identify and obtain the verification result.

[0085] In some embodiments, the prompter 210 further includes a digital display 212 , which is disposed on the box body 110 and adjacent to the display light 211 .

[0086] In this application, if Figure 1 As shown, a digital display 212 is provided on the front panel 111 of the box body 110. The digital display 212 is arranged in a one-to-one correspondence with the display light 211, and the digital display 212 is adjacent to the display light 211. For example, each digital display 212 is adjacent to each display light 211 and is distributed vertically. In a specific implementation, corresponding subtitles can be written in the digital display 212 by a programming language, such as the function description of the outlet pressure plate corresponding to the display light 211 adjacent to it is preset in the digital display 212; in this way, each display light 211 has a subtitle of the function description corresponding to each outlet pressure plate, so that the inspection personnel can quickly locate the closing condition of the specific outlet pressure plate when judging the state of the display light 211, so as to facilitate further inspection and analysis, thereby improving the convenience of use of the device.

[0087] In some embodiments, the display element 200 further includes a voice announcer 220, which is electrically connected to the controller 830; the voice announcer 220 announces the verification result on the corresponding prompter.

[0088] In this application, if Figure 1 , Figure 2 and Figure 5 As shown, a voice announcer 220 is provided on one side of the box body 110 facing the front panel 111, and the voice announcer 220 is electrically connected to the controller 830. Exemplarily, the controller 830 controls the voice announcer 220 to convert the information on the digital display 212 into voice and play it out.

[0089] In this way, the verification result is prompted by voice, so that the verification personnel user does not need to read the verification information on the display 212, and can obtain the verification result by just listening to the voice prompt, thereby saving the verification personnel time and energy and improving the verification efficiency.

[0090] In some embodiments, the box 100 further includes an adjustable bracket 120 , which includes a support plate 121 and at least two telescopic legs 122 , and the box body 110 is disposed on a surface of the support plate 121 away from the telescopic legs 122 .

[0091] The telescopic leg 122 includes a first telescopic part 1221 and a second telescopic part 1222 , one of which is slidably disposed on the other so that the two are relatively extended or shortened, and one end of the first telescopic part 1221 away from the second telescopic part 1222 is connected to the support plate 121 .

[0092] The support plate 121 and the telescopic legs 122 may be made of stainless steel or aluminum alloy, so that the adjustable bracket 120 has good strength and durability, thereby having good load-bearing capacity for the box body 110. Furthermore, the box body 110 may be fixed to the support plate 121 by fasteners, bonding or clamping.

[0093] In the embodiment of the present application, a clamping piece 1211 is provided at each vertex of the support plate 121 , and when the box body 110 is placed on the support plate 121 , the clamping piece 1211 can be used to limit its horizontal position.

[0094] In this application, if Figure 4 As shown, illustratively, the support plate 121 is a quadrilateral structure, the number of the telescopic legs 122 is four, and each telescopic leg 122 is respectively arranged at each vertex of the support plate 121, so that the support plate 121 is stably placed on the support surface.

[0095] It is understandable that the support surface can be a workbench, a desktop or the ground, etc., which is adaptively set according to the actual usage scenario. The support plate 121 can also be other shapes such as a circle. The embodiment of the present application does not limit this, as long as the box body 110 can be firmly connected to the support plate 121.

[0096] In an embodiment of the present application, an adjustable bracket 120 is provided on the box body 110 for adjusting the height of the box body 110 so that the display element 200 on the box body 110 matches the line of sight of the verification personnel. In this way, when the verification result is displayed on the display element 200, it is convenient for the verification personnel to obtain the verification result clearly and quickly.

[0097] Furthermore, the telescopic leg 122 includes a telescopic first telescopic part 1221 and a second telescopic part 1222, and the end of the first telescopic part 1221 away from the second telescopic part 1222 is connected to the support plate 121 by welding or fasteners, and the end of the second telescopic part 1222 away from the first telescopic part 1221 is used to abut against the support surface.

[0098] In some embodiments, a hinge is provided at one end of the first telescopic portion 1221 away from the second telescopic portion 1222. The hinge is provided to enable the first telescopic portion 1221 to rotate relative to the support plate 121. When the telescopic leg 122 is not needed, the telescopic leg 122 can be folded and retracted by rotating the first telescopic portion 1221, thereby increasing the applicability of the adjustable bracket 120.

[0099] In the specific setting, the first telescopic part 1221 is a columnar structure with an external thread, and the second telescopic part 1222 is a hollow columnar structure with an internal thread, and the internal thread matches the external thread. When the first telescopic part 1221 is sleeved in the second telescopic part 1222, and through the connection of the internal and external threads, the second telescopic part 1222 can be extended or shortened relative to the first telescopic part 1221.

[0100] It should be noted that the structures of the first telescopic portion 1221 and the second telescopic portion 1222 are only given for example, and it is sufficient as long as the first telescopic portion 1221 and the second telescopic portion 1222 can be connected to each other.

[0101] In actual use, the second telescopic part 1222 is rotated along the first direction to slide in the direction away from the first telescopic part 1221, or the second telescopic part 1222 is rotated along the second direction to slide in the direction close to the first telescopic part 1221; it should be noted that the first direction and the second direction are opposite directions.

[0102] In this way, the telescopic legs 122 can be extended or shortened, so that the height of the box body 110 can be raised or lowered according to the visual range of the inspector, thereby improving the convenience for the inspector to read the inspection results.

[0103] In some embodiments, the present application also includes a dustproof net 300 and a heat dissipation channel 400 disposed on the box body 110, the heat dissipation channel 400 is connected to the interior of the box body 110, and the dustproof net 300 is disposed on the box body 110 and is located at the connection point between the heat dissipation channel 400 and the box body 110.

[0104] In this application, if Figure 1 and Figure 2 As shown, a heat dissipation channel 400 is provided on the box body 110. Exemplarily, the heat dissipation channel 400 is arranged on a side of the box body 110 facing away from the support plate 121 and is connected to the box body 110 so that the heat generated when each device in the box body 110 is turned on can be dissipated through the heat dissipation channel 400.

[0105] Furthermore, a dustproof net 300 is provided at the connection point between the heat dissipation channel 400 and the box body 110. Specifically, the dustproof net 300 is fixed to the box body 110 by fasteners or the like. By providing the dustproof net 300, it is difficult for external foreign matter or pollutants to enter the box body 110 through the heat dissipation channel 400, thereby ensuring the normal operation of various components in the box body 110.
