Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of power supply test equipment, and in particular to a cable phase checking system, method, device, equipment and storage medium. Background Art

[0002] As the cableization rate of urban distribution network lines increases, there are more and more cable construction projects. The cables of medium-voltage distribution lines often need to be repaired, spliced, reconnected, and new cable distribution boxes and distribution rooms added. Due to the loss or error of the cable phase sequence marking, and the untimely communication of multi-section construction information, it is easy to cause the phase sequence of the newly added cables and equipment to be wrong after the cable construction is completed. Therefore, after the cable operation is completed, a phase check test is required to ensure that the three-phase phase sequence remains consistent with that before the construction after the distribution equipment is changed. The wrong phase sequence will cause serious problems such as the user's motor reversal and the inability of the two power supplies to close the loop normally.

[0003] After the running cable is cut, the construction personnel usually use color tape to mark the three-phase sequence of the cables at both ends of the breakpoint with A, B, and C. After the construction is completed, the new equipment is started to supply power. After the two power supplies are sent to the closing point, the phase sequence error caused by the construction can be discovered only after manual phase checking. Because the planned power outage time arranged by the grid dispatch is limited and cannot affect the timely restoration of power supply to users, it is too late to discover the cable phase sequence error and adjust the phase sequence at this time. It is usually necessary to rearrange the power outage plan and adjust the phase sequence later. Adjusting the phase sequence again afterwards will cause repeated power outages for users, and the cost of remaking the cable joints is high.

[0004] Therefore, how to perform phase checking on the cable without affecting the timely restoration of power supply to users is a problem that needs to be solved in the prior art. Summary of the invention

[0036] Embodiment 1

[0037] Figure 1 A schematic diagram of the structure of a cable phase checking system provided in Embodiment 1 of the present invention is provided. The system can be applied to the situation of performing phase checking on a cut or newly added cable during cable construction. The system can execute a cable phase checking method.

[0038] like Figure 1 As shown, a cable phase checking system provided by the first embodiment of the present invention includes: a signal sending device 10, a signal receiving device 20 and a controller 30, wherein the controller 30 is connected to the signal sending device 10 and the signal receiving device 20 respectively;

[0039] The controller 30 is used to perform matching verification on the signal sending device 10 and the signal receiving device 20;

[0040] The signal sending device 10 is used to send a high-frequency signal from the outgoing cable terminal head of the cable distribution box after matching verification;

[0041] The signal receiving device 20 is used to receive the high-frequency signal at different cable segmentation points of the construction cable, and the received high-frequency signal is used to compare with the transmitted high-frequency signal to obtain a phase verification result.

[0042] The controller 30 may be connected to the signal sending device 10 and the signal receiving device 20 by wireless. The signal sending device 10 may be a terminal for sending high-frequency signals, and the signal receiving device 20 may be a terminal for receiving high-frequency signals. The terminal of this embodiment may have the functions of sending and receiving signals at the same time, or may only have the functions of sending or receiving signals, which is not limited in this embodiment.

[0043] In this embodiment, one controller 30 can control one or more signal sending devices 10 and signal receiving devices 20. The controller 30 can perform a matching check on the signal sending device 10 and the signal receiving device 20 to ensure that signal sending and receiving are normal.

[0044] Among them, the cable junction box can be a device used to implement tapping, branching, connection and conversion circuits for cable lines. The outgoing cable terminal head can be the location where the cable terminal head is outgoing. The cable terminal head is a device assembled to the head and end of the cable line to complete the connection with other electrical equipment. In the field of electrical engineering, the outgoing line refers to the wire or cable that distributes power from the electrical equipment and transmits the electrical energy to various loads, and the incoming line refers to the cable or wire that transmits power from the power source to the building or equipment. High-frequency signals can be signals with higher frequencies. Construction cables can be cables that need to be phase-checked during the construction process. The cable segmentation point can be the place where the cable is cut or needs to be phase-checked. For example, if a cable is divided into two sections, the two ends of the cut cable need to be phase-checked. The phase-check result can be the same phase or different phases.

[0045] In this embodiment, the high-frequency signal sent by the signal sending device 10 may include three high-frequency signals of different frequencies. The three phases ABC of the cable can be phase-checked at the same time. The frequencies of the signals added to different phases are different. Phase A (1MHz), phase B (10MHz), phase C (20MHz), or phase A (square wave), phase B (sawtooth wave), phase C (sine wave) and other high-frequency signals with easy-to-identify, anti-interference, and non-easy-to-attenuate characteristics can be used. Alternatively, a phase-by-phase check method can be used, such as checking phase A first, then phase B, and then phase C. At the same time, compared with the phase-by-phase check method, the phase check does not need to discharge and add signals every time the phase check is completed, which is more efficient.

[0046] In this embodiment, the construction personnel apply a high-frequency signal at one end of the disconnection point of the construction cable through the signal sending device 10. The high-frequency signal passes through the ABC three-phase of the cable core and the newly added equipment (equipment that has been changed during construction) to reach another cable segmentation point. The signal receiving device 20 receives the signal at another cable segmentation point, and obtains the phase verification result by comparing the signals at both ends, thereby obtaining the correct three-phase phase sequence.

[0047] For example, Figure 2 A schematic diagram of a construction cable before being cut provided by an embodiment of the present invention, Figure 3 A schematic diagram of a construction cable core phase provided by an embodiment of the present invention. Figure 2 and Figure 3 As shown, the construction content is to cut the cables between the #1 public cable distribution box and the #2 public cable distribution box, and connect them to the new #3 public cable distribution box. Figure 3 The terminal in the device has both sending and receiving functions. The receiver / transmitter includes a coupling capacitor C1, a connection filter L and a grounding switch G. When adding signals of different frequencies, three different signals can be added at the same time by adjusting the parameters of the coupling capacitor and the filter. The grounding switch is used to discharge after the signal is loaded to ensure personal safety.

[0048] Furthermore, the phase checking method can include full-section phase checking and segmented phase checking. Full-section phase checking refers to the process of performing phase detection and consistency confirmation on the entire power line or equipment from beginning to end. Segmented phase checking divides the power system into multiple parts, and each part performs phase detection and confirmation separately.

[0049] For example, Figure 4 A schematic diagram of a full-segment core phase provided by an embodiment of the present invention, such as Figure 4 As shown, the signal sending device and the signal receiving device are respectively arranged at both ends of all construction cables that need phase checking. Figure 5 A schematic diagram of a segmented core phase provided by an embodiment of the present invention, such as Figure 5 As shown, the signal receiving device can be set at the segmentation point of each construction cable that needs phase verification.

[0050] A cable phase checking system provided in the first embodiment of the present invention includes: a signal sending device, a signal receiving device and a controller, wherein the controller is connected to the signal sending device and the signal receiving device respectively; the controller is used to perform matching verification on the signal sending device and the signal receiving device; the signal sending device is used to send a high-frequency signal from the outgoing cable terminal head of the cable junction box after matching verification; the signal receiving device is used to receive the high-frequency signal at different cable segmentation points of the construction cable, and the received high-frequency signal is used to compare with the sent high-frequency signal to obtain a phase checking result. The system can obtain the phase checking result of the construction cable by sending and receiving high-frequency signals at both ends of the construction cable and comparing them, thereby ensuring that the phase sequence of the construction cable is correct, and solving the problem in the prior art that the cable phase cannot be checked without affecting the power supply to the user.

[0051] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0052] In one embodiment, the number of the signal sending device 10 and the signal receiving device 20 is one or more, and accordingly,

[0053] The controller 30 is specifically used to: receive the physical addresses sent by each signal sending device 10 and each signal receiving device 20, assign device numbers to each signal sending device 10 and each signal receiving device 20 according to each physical address, and send each device number to the corresponding signal sending device 10 or signal receiving device 20;

[0054] The signal sending device 10 is further used to receive a corresponding device number, update a local device number according to the corresponding device number, and complete a matching check of the signal sending device 10;

[0055] The signal receiving device 20 is further used to receive a corresponding device number, update a local device number according to the corresponding device number, and complete a matching check of the signal receiving device 20 .

[0056] The physical address may be the location of the device at the construction site. The device number may be a number assigned to the device by the controller, and the device number may be set according to the location of the device at the site.

[0057] In this embodiment, all signal sending devices 10 and signal receiving devices 20 can be connected to the local area network established by the controller 30, and their respective physical addresses can be sent to the controller 30. According to the physical address, the controller 30 sets the signal sending device number to FS#01, F#02, ..., F#0n according to the on-site construction requirements. The signal receiving device number is set to JS#01, JS#02, ..., JS#0n. A one-key matching button can be set on the controller 30. After the button is activated, the device number is automatically sent to different devices one by one. After the signal sending device 10 and the signal receiving device receive the device number, the previously saved device number is cleared and the new identity number is saved, thereby completing the matching verification.

[0058] In one embodiment, the signal sending device 10 and the signal receiving device 20 further include an indicator light, which is used to light up according to a preset indication rule after the signal sending device 10 or the signal receiving device 20 receives the device number.

[0059] The indicator light may be a light that can emit different colors. The preset indication rule may be a state in which the indicator light is lit correspondingly after receiving the device number.

[0060] In this embodiment, the signal sending device 10 and the signal receiving device 20 may also include an indicator light. When the signal sending device 10 or the signal receiving device 20 receives the device number, the indicator light may light up according to a preset indication rule. Exemplarily, after the signal sending device 10 or the signal receiving device 20 receives the device number, the indicator light may light up green and flash three times before going out to indicate that the signal sending device 10 or the signal receiving device 20 has received the device number. If a device does not respond or the response delay is large (more than 3s), the automatic device number issuance function is suspended, and the matching information of this device needs to be manually cleared or manually verified separately. Furthermore, the controller may also be provided with a separate verification button to facilitate subsequent targeted identity matching verification of a single device.

[0061] In one embodiment, the controller 30 is further configured to:

[0062] Sending the recovery signal to the signal sending device 10 and the signal receiving device 20, and receiving the identity information returned by the signal sending device 10 and the signal receiving device 20 according to the recovery signal;

[0063] When it is determined that the identity information is consistent with the locally stored information, a de-matching signal is sent to the signal sending device 10 and the signal receiving device 20 .

[0064] The recycling signal may be a signal for indicating the recycling device number. The identity information may include information such as the unique identification of the device and the assigned device number. The contact matching signal may be a signal for indicating that the device clears the matched information.

[0065] In this embodiment, the controller 30 can also recover the device number sent during the previous matching check. Specifically, it can send a recovery signal to the signal sending device 10 and the signal receiving device 20, receive the identity information returned by each device, and determine whether the corresponding device is consistent with the information stored locally based on the identity information. If so, a cancellation signal can be sent to the corresponding device.

[0066] Exemplarily, a one-key recycling button can also be set on the controller 30. After the button is activated, the signal sending device 10 and the signal receiving device 20 actively upload the saved identity information and light up the green indicator light (keep it on) in response. If the information saved by the controller 30 matches the identity information of each device, the corresponding mark of the terminal management interface of the controller 30 flashes, and the binding is manually untied after confirmation. After each device receives the unmatching signal, the green indicator light goes out and the saved device number is cleared. If there is a device that has not uploaded its identity information, the mark recycling fails, and the device needs to be retrieved and the button restarted.

[0067] In one embodiment, the signal sending device 10 is further used to: after receiving the unmatching signal, clear the device number stored locally;

[0068] The signal receiving device 20 is further configured to clear the locally stored device number after receiving the cancellation signal.

[0069] In this embodiment, after receiving the contact matching signal, the signal sending device 10 and the signal receiving device 20 can clear the device numbers stored locally.

[0070] In one embodiment, the signal sending device 10 is disposed at the outgoing cable terminal head of the cable junction box on the power supply side of the initial segmentation point of the construction cable, and the signal receiving device 20 is disposed at different segmentation points of the construction cable.

[0071] The initial segmentation point may be the first segmentation point of the phase to be checked in the direction from the incoming line to the outgoing line of the construction cable of the phase to be checked. Figure 3 As shown, the construction cable has two cutting points, where F1 is the incoming line direction and #1 is the cable junction box closest to the initial segmentation point.

[0072] In this embodiment, the signal sending device 10 can be set at the outgoing cable terminal head of the cable junction box on the power supply side of the initial segmentation of the construction cable, and the signal receiving device 20 can be set at different segmentation points of the construction cable. In the subsequent process of checking the phase of other segmentation points, the position of the signal sending device 10 can remain unchanged. If the position of the signal sending device 10 needs to be changed, it can only be changed to a position where the phase has been checked.

[0073] The embodiments of the present invention provide several specific implementation methods based on the technical solutions of the above embodiments.

[0074] As a specific implementation method of this embodiment, when the phase is cored by a segmented core phase, such as Figure 3 As shown, the construction personnel can use the signal sending device to inject a high-frequency signal from the outgoing cable terminal head of the #1 cable junction box; receive the signal at the first segmentation point of the cable to ensure the correct phase sequence, and then connect the first cable middle head; when checking the phase of the next segmentation point, the signal injection position remains unchanged, and receive the signal at the second segmentation point of the cable to ensure the correct phase sequence, and then connect the second cable middle head; check the phase section by section in turn to ensure the correct phase sequence of each newly connected device.

[0075] When the phase is checked by the whole section phase checking method, after the construction is completed and before the equipment starts to supply power, the signal injection position remains unchanged, and the signal is received at the incoming cable head of the #2 public cable junction box.

[0076] During the circuit startup process, active phase checking can be further performed on both sides of the closing point of the #2 public cable junction box, and compared with the phase checking results obtained through segmented phase checking or full-segment phase checking to ensure that the power phase sequence on both sides of the closing point is consistent.
