Example 2

[0021] like Figure 1-5 As shown, the present embodiment discloses a user-to-user transformer relationship error troubleshooting device, which includes a troubleshooting device body 1, the troubleshooting device body 1 includes a wiring port 2 arranged at the upper end, a wiring post 8 is arranged inside the wiring port 2, and the wiring post 8 is connected to a voltage acquisition circuit 23 in the troubleshooting device body 1. The voltage acquisition circuit 23 is provided with a wire clamp through the wiring post 8, and the wire clamp clamps the user transformer harness of the user-to-user transformer relationship to be checked and collects its voltage data. The voltage acquisition circuit 23 is also connected to a collection module 22 in the troubleshooting device body 1, and the collection module 22 is connected to a CUS bus 18, and the CUS bus 18 is connected to a CPU processor 17, and the CPU The processor 17 and the CUS bus 18 are both connected to a control module 19, and the control module 19 is connected to a display 3 arranged at the upper end of the front surface of the troubleshooting device body 1 and a control panel 5 arranged at the lower end of the display 3.

[0022] In this embodiment, a terminal 8 is provided on the inner side of the wiring port 2, and a wire clamp is provided through the terminal 8, so that the wire clamp can be clamped on the transformer harness of the user whose household-to-transformer relationship needs to be checked, and the power consumption of the user to be checked is obtained, and at the same time, the voltage data corresponding to the power supply unit of the user to be checked is obtained, so that according to the correlation coefficients corresponding to each user to be checked, it is determined whether the voltage data corresponding to each user matches the voltage data corresponding to the power supply unit, and whether the household-to-transformer relationship of the user to be checked is wrong.

[0023] The specific steps are as follows: Step S1, obtaining voltage data corresponding to the target user and voltage data corresponding to the power supply unit.

[0024] In this step, obtaining the voltage data corresponding to each user in the household-to-household change relationship error troubleshooting may be obtaining the voltage curve corresponding to each user, wherein the users in the household-to-household change relationship error troubleshooting may include low-voltage users and public-to-household change relationship error troubleshooting; the voltage data corresponding to the power supply unit obtained may also be obtaining the voltage curve of the power supply unit. Under normal circumstances, the voltage curve of the user should be similar to the voltage curve of the target household-to-household change relationship error troubleshooting. Therefore, obtaining the voltage data of the user and the household-to-household change relationship error troubleshooting may be used for subsequent judgment as to whether there is an error in the user's household-to-household change relationship.

[0025] Step S2, comparing the voltage data corresponding to the target user and the voltage data corresponding to the power supply unit with the data under normal conditions, and determining whether they match.

[0026] In this step, under normal circumstances, the user's voltage data should match the voltage data corresponding to the power supply unit; if there is a situation where the user's voltage data does not match the voltage data corresponding to the power supply unit, it can be considered that the user may have an error in the household change relationship, and when the user is under power outage, it should be impossible to obtain the voltage data of the user in the household change relationship error investigation. Therefore, when the household change relationship error investigation is in a power outage, the corresponding voltage data of the user can still be obtained, it can be considered that the user may be a user with an incorrect household change relationship. Specifically, it can be judged by comparing the user's voltage data in the power outage state with a preset threshold. If the voltage data exceeds the preset threshold, it can be considered that the corresponding user may be a user with an incorrect household change relationship.

[0027] Step S3, judging whether the voltage data corresponding to the user matches the voltage data corresponding to the power supply unit according to step S2.

[0028] In this step, specifically, whether the voltage data matches can be determined by the correlation coefficient between the voltage data corresponding to the user and the voltage data corresponding to the power supply unit. For example, the Pearson correlation coefficient between the user voltage data and the voltage data of the power supply unit can be calculated. The higher the coefficient, the higher the similarity. Whether the voltage data matches is determined based on the correlation coefficient.

[0029] Step S4, based on the above steps S1-S4, it is determined whether the target in the household change relationship error troubleshooting is a user with a household change relationship error.

[0030] Through the above steps, the purpose of determining abnormal household-to-household change users according to user voltage data is achieved, thereby realizing the technical effect of improving the efficiency of detecting users with abnormal household-to-household change relationships, and further solving the technical problem of long time and low efficiency in detecting users with abnormal household-to-household change relationships in related technologies.
