Description

TECHNICAL FIELD

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

[0002] With the increasing rate of cable in urban distribution network lines, cable construction projects are also increasing. The cables of medium-voltage distribution lines often need to be repaired, connected, modified, and new cable distribution boxes and distribution rooms are added. Due to the loss, error, and delayed communication of cable phase sequence markers, and other reasons, it is easy to cause the phase sequence error between the new cable and the equipment after the completion of the cable construction. Therefore, after the completion of the cable operation, a phase checking test is needed to ensure that the three-phase sequence of the distribution equipment remains consistent before and after the construction, and the phase sequence error will cause serious problems such as user motor reverse rotation and two-way power supply unable to normally close the loop.

[0003] After the cable is cut in operation, the three-phase sequence of the cable at both ends of the breakpoint is usually marked with color bands. After the completion of the construction, the new equipment is started and power is supplied, and after the two-way power supply is supplied to the closing point, the phase sequence error caused by the construction can be found after the manual phase checking. Because of the limited planned power outage time arranged by the power grid dispatching, it cannot affect the timely restoration of power supply to users, and at this time, it is too late to find and adjust the cable phase sequence error, and it is usually necessary to re-arrange the power outage plan for phase sequence adjustment. Subsequent adjustment of the phase sequence will cause repeated power outages to users, and the cost of re-making the cable joint is high.

[0004] Therefore, how to check the phase of the cable without affecting the timely restoration of power supply to users is a problem to be solved in the prior art. SUMMARY

[0036] Embodiment one

[0037] Figure 1 A structural schematic diagram of a cable phase checking system provided by embodiment one of the present application, the system can be applied to the case of checking the phase of the cable after cutting or adding, and the system can execute a cable phase checking method.

[0038] As Figure 1 shown, the cable phase checking system provided by embodiment one of the present application comprises a signal sending device 10, a signal receiving device 20 and a controller 30, the controller 30 is connected with the signal sending device 10 and the signal receiving device 20 respectively;

[0039] The controller 30 is used for matching verification of the signal sending device 10 and the signal receiving device 20.

[0040] The signal sending device 10 is used for sending high frequency signals from the outgoing cable terminal head of the cable distribution box after matching verification.

[0041] The signal receiving device 20 is used for receiving the high frequency signals at different cable segment points of the construction cable, and the received high frequency signals are used for comparison with the sent high frequency signals to obtain the phase checking result.

[0042] Among them, the controller 30 and the signal sending device 10 and the signal receiving device 20 can be connected through wireless connection. The signal sending device 10 can be a terminal for sending high frequency signals, and the signal receiving device 20 can be a terminal for receiving high frequency signals. The terminal of the present embodiment can have the functions of sending and receiving signals at the same time, or can only have the functions of sending signals or receiving signals, and the present embodiment does not limit this.

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

[0044] The cable distribution box can be a device for implementing distribution, branching, splicing and circuit conversion of a cable line. The outgoing cable terminal head can be a position of the outgoing cable terminal head. The cable terminal head is a device assembled to the first and last end of the cable line to complete the connection with other electrical equipment. In the field of electrical engineering, the outgoing line refers to a wire or cable that distributes power from electrical equipment to various loads, and the incoming line refers to a cable or wire that transports power from a power source to a building or equipment. The high-frequency signal can be a signal with a relatively high frequency. The construction cable can be a cable that needs to be phase checked during construction. The cable segmentation point can be a 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 checking result can be in phase or out of phase.

[0045] In this embodiment, the high-frequency signal sent by the signal sending device 10 can include three high-frequency signals with different frequencies, and the ABC three phases of the cable can be simultaneously phase checked. The signal frequencies on different phases are different, and A phase (1 MHz), B phase (10 MHz), C phase (20 MHz), or A phase (square wave), B phase (sawtooth wave), C phase (sine wave) and other high-frequency signals with easy identification, anti-interference and non-decay characteristics can be used. Alternatively, the phase-by-phase phase checking mode can also be used, such as first checking A phase, then checking B phase, and then checking C phase. The simultaneous phase checking does not need to discharge and add signals every time the phase checking is completed, and the efficiency is higher.

[0046] In this embodiment, the construction personnel applies a high-frequency signal to one end of the construction cable break point through the signal sending device 10. The high-frequency signal passes through the ABC three phases of the cable core and reaches the other cable segmentation point through the newly added device (the device changed by construction). The signal receiving device 20 receives the signal at the other cable segmentation point, obtains the phase checking result by comparing the signals at both ends, and obtains the correct three-phase sequence.

[0047] As shown in the examples, Figure 2 A schematic diagram of a construction cable before cutting provided by the embodiment of the present application, Figure 3 A schematic diagram of the construction cable phase checking provided by the embodiment of the present application. As shown in Figure 2 and Figure 3 The construction content is to cut the cable between the #1 public cable distribution box and the #2 public cable distribution box and connect a new #3 public cable distribution box. Figure 3 The terminal in the signal sending device 10 simultaneously has the functions of signal sending and signal receiving. The signal receiving / sending device includes a coupling capacitor C1, a filter L and a grounding switch G. When different frequency signals are added, 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] Further, the phase checking manner can include full-segment phase checking and segmented phase checking. The full-segment phase checking refers to a process of performing phase detection and consistency confirmation on the entire power line or device from head to tail. The segmented phase checking refers to dividing the power system into multiple segments, and performing phase detection and confirmation on each segment separately.

[0049] Exemplarily, Figure 4 A full-segment phase checking schematic diagram provided for an embodiment of the present application is shown in FIG. 1. Figure 4 As shown in FIG. 1, the signal sending device and the signal receiving device are respectively arranged at both ends of the construction cable that needs to be checked in phase. Figure 5 A segmented phase checking schematic diagram provided for an embodiment of the present application is shown in FIG. 2. Figure 5 As shown in FIG. 2, the signal receiving device can be arranged at the segmented point of each segment of the construction cable that needs to be checked in phase.

[0050] The cable phase checking system provided by the embodiment one comprises a signal sending device, a signal receiving device and a controller, the controller is connected with the signal sending device and the signal receiving device respectively, the controller is configured to perform matching verification on the signal sending device and the signal receiving device, the signal sending device is configured to send a high-frequency signal from the outgoing cable terminal head of the cable distribution box after the matching verification, and the signal receiving device is configured to receive the high-frequency signal at different cable segmented points of the construction cable, and the received high-frequency signal is configured to be compared 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 the high-frequency signal at both ends of the construction cable and comparing the high-frequency signals, and can ensure the correct phase sequence of the construction cable, thereby solving the problem that the cable phase checking cannot be performed without affecting the power supply of users in the prior art.

[0051] On the basis of the above-mentioned embodiments, variant embodiments of the above-mentioned embodiments are provided, and it should be noted that, in order to make the description brief, only the differences between the variant embodiments and the above-mentioned embodiments are described in the variant embodiments.

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

[0053] The controller 30 is specifically configured to receive the physical addresses sent by each signal sending device 10 and each signal receiving device 20, allocate a device number 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 configured to receive the corresponding device number, update the local device number according to the corresponding device number, and complete the matching verification of the signal sending device 10;

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

[0056] The physical address can be the position of the device on the construction site. The device number can be a number assigned to the device by the controller, and the device number can be set according to the position of the device on 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 the respective physical addresses can be uploaded 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, and the signal receiving device number to JS#01, JS#02,..., JS#0n according to the construction requirements on the site. The controller 30 can be provided with a one-key matching button. After the button is started, the device number is automatically issued 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 check.

[0058] In one embodiment, the signal sending device 10 and the signal receiving device 20 further include an indicator light. The indicator light is configured 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 can be a light that can emit different colors. The preset indication rule can be the state of the indicator light corresponding to the state of the indicator light after receiving the device number.

[0060] In this embodiment, the signal sending device 10 and the signal receiving device 20 can further include an indicator light. When the signal sending device 10 or the signal receiving device 20 receives the device number, the indicator light can light up according to a preset indication rule. For example, after the signal sending device 10 or the signal receiving device 20 receives the device number, the indicator light can light green and flash three times and then turn off, indicating 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 issuing function is suspended, and the matching information of this device needs to be manually cleared or manually checked individually. Further, the controller can also be provided with an individual check button to facilitate subsequent targeted identity matching check of individual devices.

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

[0062] The recycling signal is sent to the signal sending device 10 and the signal receiving device 20, and the signal receiving device 20 returns identity information according to the recycling signal;

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

[0064] The recycling signal can be a signal for indicating the recycling device number. The identity information can include the unique identification of the device and the allocated device number and the like. The contact matching signal can be a signal for indicating that the device clearly matches the information.

[0065] In the embodiment, the controller 30 can also recycle the device number sent during the previous matching verification. Specifically, the recycling signal can be sent to the signal sending device 10 and the signal receiving device 20, and the identity information returned by each device is received, and it is determined according to the identity information whether the corresponding device is consistent with the information stored locally. If so, the match release signal can be sent to the corresponding device.

[0066] For example, a one-key recycling button can also be provided on the controller 30. After the button is started, the signal sending device 10 and the signal receiving device 20 actively send the saved identity information, and a green indicator light (always on) is answered. If the identity information of each device matches the information saved by the controller 30, the corresponding identification of the terminal management interface of the controller 30 flashes, and after confirmation, the binding is manually released. After receiving the match release signal, each device extinguishes the green indicator light and clears the saved device number. If there is a device that does not send the identity information, it is marked as recycling failure, and the device needs to be collected and the button is restarted.

[0067] In one embodiment, the signal sending device 10 is also used to clear the locally saved device number after receiving the match release signal.

[0068] The signal receiving device 20 is also used to clear the locally saved device number after receiving the match release signal.

[0069] In the embodiment, the signal sending device 10 and the signal receiving device 20 can clearly save the device number locally after receiving the contact matching signal.

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

[0071] The initial segmentation point can be the first segmentation point to be phase checked in the direction from the incoming line to the outgoing line of the construction cable to be phase checked. For example,Figure 3 As shown in the figure, the construction cable has two cut-off points, and F1 direction is the incoming line direction, and #1 is the cable distribution box closest to the initial section point.

[0072] In this embodiment, the signal sending device 10 can be arranged at the outgoing cable terminal head of the cable distribution box on the power supply side of the initial section of the construction cable, and the signal receiving device 20 can be arranged at different section points of the construction cable. During the subsequent phase checking of other section points, the position of the signal sending device 10 can remain unchanged. If it is necessary to change the position of the signal sending device 10, it can only be changed to the position that has been checked.

[0073] The embodiments of the present application provide several specific implementation manners on the basis of the technical solutions of the above-mentioned embodiments.

[0074] As a specific implementation manner of the present application, when the phase checking is performed by the section-by-section phase checking manner, as shown in the figure, Figure 3 the construction personnel can inject a high-frequency signal from the outgoing cable terminal head of the #1 cable distribution box by using the signal sending device; the signal is received at the first section point of the cable to ensure that the phase sequence is correct, at which time the first cable intermediate head can be connected; when the next section point is checked, the signal injection position remains unchanged, and the signal is received at the second section point of the cable to ensure that the phase sequence is correct, at which time the second cable intermediate head can be connected; the section-by-section phase checking is sequentially performed to ensure that the phase sequence of each newly connected device is correct.

[0075] When the phase checking is performed by the full-section phase checking manner, after the construction is completed, before the device is started and power is supplied, the signal injection position remains unchanged, and the signal is received at the incoming cable head of the #2 public cable distribution box.

[0076] During the circuit starting process, active phase checking can be further performed, and the phase checking is performed on both sides of the closing point of the #2 public cable distribution box, and the phase checking result obtained by the section-by-section phase checking or the full-section phase checking is compared to ensure that the phase sequences of the power supplies on both sides of the closing point are consistent.
