The volt-ampere meter has a low degree of intelligence and low operating efficiency. In addition, since most electrical equipment has a meter box seal that cannot be opened at will, the existing inspection devices cannot quickly and accurately perform wiring acceptance or inspection on the electrical equipment.

[0019] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention 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 data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] Figure 1 A schematic diagram of a power consumption inspection device provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the power inspection device includes a detection module 10 and a host module 20 which are electrically connected in sequence; the detection module 10 is used to obtain the working parameters of the power equipment and send the working parameters to the host module 20; the host module 20 is used to check whether there is any abnormality in the power equipment according to the working parameters.

[0022] Among them, the electrical equipment includes but is not limited to electricity meters, electricity metering equipment or other electrical equipment. It can be understood that the electrical equipment and the detection module 10 can be electrically connected or communication connected so that the detection module 10 can collect the working parameters of the electrical equipment. The working parameters include but are not limited to three-phase voltage, three-phase current, electric energy, phase sequence of three-phase voltage and the angle between each phase voltage and the corresponding phase current in the three-phase voltage, etc. Depending on the actual needs, the working parameters obtained by the detection module 10 will also be different, and the embodiment of the present invention is not limited to this.

[0023] Specifically, the detection module 10 can obtain the working parameters of the electrical equipment by communicating with the electrical equipment, and can adopt wired communication or wireless communication, including but not limited to adopting infrared serial port communication to obtain the working parameters, which is not limited in the embodiment of the present invention. In this way, for different electrical equipment, the working parameters of the electrical equipment can be quickly and accurately obtained and sent to the host module without opening the lead seal to disassemble the electrical equipment. At the same time, after receiving the working parameters of the electrical equipment collected by the detection module 10, the host module 20 can perform further processing and analysis according to the working parameters, for example, according to the obtained working parameters, calculate whether the phase sequence of the three-phase voltage is in line with the actual situation, or whether there is a line connection error, or whether there is leakage, electricity theft, etc., or whether the electricity rate is correct, etc., so as to determine whether the electrical equipment is normal. Therefore, compared with the existing device for inspecting electrical equipment, this embodiment can quickly and accurately inspect the electrical equipment without opening the lead seal of the electrical equipment through the detection module 10, which is simple and easy to operate, highly safe, more practical and has a wide range of applications, thereby improving the work efficiency of technicians in inspecting electrical equipment.

[0024] In the embodiment of the present invention, the working parameters of the electrical equipment are obtained by the detection module, and the working parameters are sent to the host module. The host module checks whether there is any abnormality in the electrical equipment according to the working parameters. In this way, when the technician inspects the electrical equipment, there is no need to open the lead seal of the electrical equipment. While ensuring safety, it has a wider application range, can quickly and accurately inspect the electrical equipment, is simple and easy to operate, has high safety, is more practical and has a wide range of applications, thereby improving the work efficiency of the technician in inspecting the electrical equipment.

[0025] Optionally, the detection module 10 includes an infrared detection module; the infrared detection module is used to communicate with the electrical device to obtain the working parameters of the electrical device.

[0026] Specifically, the infrared detection module usually includes an infrared photoelectric head, which can communicate with the electrical equipment and collect various parameters and data in the electrical equipment. In addition, the infrared detection module can also include a suction cup, which is attached to the outer shell of the electrical equipment through the suction cup, so that the technician can avoid direct contact with the electrical equipment when inspecting the electrical equipment, thereby ensuring safety.

[0027] Optionally, the electrical equipment includes an electric energy meter.

[0028] It is understandable that an electric energy meter is generally an instrument used to measure electric energy, also known as an electric meter, a fire meter, a kilowatt-hour meter, etc. The specific types of electric energy meters vary according to their uses, structures, and wiring methods, including but not limited to three-phase single-phase electric energy meters or three-phase four-wire electric energy meters, etc., which are not limited in the embodiments of the present invention.

[0029] Optional, Figure 2 A schematic diagram of the structure of another power inspection device provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the host module 20 includes an electrically connected control unit 21 and a display unit 22; the working parameters of the electrical equipment 20 include the phase sequence of the three-phase voltage and the angle between each phase voltage in the three-phase voltage and the corresponding phase current; the control unit 21 is used to generate a hexagonal diagram according to the phase sequence of the three-phase voltage and the angle between each phase voltage in the three-phase voltage and the corresponding phase current; the display unit 22 is used to display the hexagonal diagram.

[0030] Among them, the phase sequence of the three-phase voltage includes a positive phase sequence and a negative phase sequence (also called a reverse phase sequence).

[0031] Specifically, the detection module 10 can obtain the phase sequence of the three-phase voltage by obtaining the internal status word in the electrical device. It can be understood that the definition of the internal status word in different electrical devices will also be different. For example, Table 1 is a schematic diagram of an electric meter operation status word provided in an embodiment of the present invention. As shown in Table 1, the electric meter operation status word is 16-bit data, wherein Bit0 is a voltage reverse phase sequence flag, and the status word is usually identified by a binary number. For example, when Bit0=1, it indicates that the three-phase voltage is in reverse phase sequence, that is, the wiring of the three-phase voltage is in reverse phase sequence. At this time, the status word of the corresponding electric meter is 00000001. Similarly, when Bit0=0, it indicates that the three-phase voltage is in positive phase sequence, that is, the wiring of the three-phase voltage is in positive phase sequence. At this time, the status word of the corresponding electric meter is 0000 0000.

[0032] Table 1: Schematic diagram of an electric meter operation status word

[0033]

[0034] Furthermore, the detection module 10 can also directly obtain the angle between each phase voltage and the corresponding phase current in the three-phase voltage, that is, the angle JA between the A phase voltage Ua and the A phase current Ia, the angle JB between the B phase voltage Ua and the B phase current Ia, and the angle JC between the C phase voltage Ua and the C phase current Ia. Taking into account the different loads applied by the electrical equipment, the angle size and the lead-lag relationship between each phase voltage and the corresponding phase current are also different, so the hexagonal diagram generated by the control unit 21 will also be different.

[0035] For example, taking the load of the electrical equipment as an inductive load, Figure 3 A hexagonal diagram of a three-phase voltage positive phase sequence provided by an embodiment of the present invention, such as Figure 3As shown, since the three-phase voltage is in positive phase sequence and the phase angle difference between every two phases of the three-phase voltage is 120 degrees, the phase angle of Ua leads the phase angle of Ub by 120 degrees, the phase angle of Ub leads the phase angle of Uc by 120 degrees, and the phase angle of Uc leads the phase angle of Ua by 120 degrees. Since the load of the electrical equipment is an inductive load, the phase angle of the current corresponding to the same phase lags behind the phase angle of the voltage. Figure 3 A hexagonal diagram with JA, JB and JC of 30 degrees is shown as an example.

[0036] Based on the same principle, Figure 4 A hexagonal diagram of a three-phase voltage reverse phase sequence provided by an embodiment of the present invention can be referred to Figure 4 The control unit 21 can also generate a hexagonal diagram according to the phase sequence of the three-phase voltage and the angle between each phase voltage and the corresponding phase current in the three-phase voltage, which will not be described in detail here. It can be understood that Figure 4 It is shown for exemplary purposes only. Depending on the load characteristics of the electrical equipment and the specific angles of JA, JB and JC, the hexagonal diagram finally generated will also be different. The corresponding hexagonal diagram can be generated according to the actual situation.

[0037] Furthermore, the hexagonal diagram generated by the control unit 21 can be displayed by the display unit 22, so that technicians can directly determine whether the line connection of the electrical equipment is correct and whether the voltage and current are consistent with the actual power consumption through the hexagonal diagram, so as to further determine whether there is leakage, power theft and other abnormal conditions.

[0038] Optional, continue to refer to Figure 2 As shown, the electrical equipment includes three-phase four-wire electrical equipment and three-phase three-wire electrical equipment; the control unit 21 is also used to determine the type of electrical equipment before generating a hexagonal diagram based on the phase sequence of the three-phase voltage and the angle between each phase voltage and the corresponding phase current in the three-phase voltage.

[0039] Specifically, since the specific wiring types of actual electrical equipment may differ, the working parameters obtained by the detection module 10 may deviate from the actual wiring, and the hexagonal diagram generated by the control unit may also be different. Therefore, the control unit 21 needs to determine the type of electrical equipment before generating the hexagon in order to draw an accurate hexagonal diagram for technical personnel to further observe and troubleshoot abnormal situations.

[0040] For example, take the case where the electrical equipment is a three-phase three-wire electrical equipment and the load of the electrical equipment is an inductive load. Since the three-phase three-wire electrical equipment is usually measured with reference to phase B, that is, the angle JB is 0. At this time, the angle between each phase voltage and the corresponding phase current in the three-phase voltage acquired by the detection module 10 is actually the angle between the line voltage and the phase current. For example, the angle JA between the A phase voltage Ua and the A phase current Ia is actually the angle between the line voltage Uab and the phase current Ia. The line voltage Uab is the voltage synthesized by the phase voltage Ua and the phase voltage Ub. Taking the phase sequence of the three-phase voltage as the positive phase sequence as an example, Figure 5 Another hexagonal diagram of three-phase voltage reverse phase sequence provided by the embodiment of the present invention is as follows: Figure 5 As shown, since the phase voltages Ua, Ub and Uc are voltages of equal amplitude, the angle between the obtained line voltage Uab and the phase voltage Ua is 30 degrees. At this time, if the angle of JA and JC obtained by the detection module 10 is 30 degrees as an example, in the generated hexagonal diagram, the phase current Ia leads the line voltage Uab by 30 degrees, that is, the phase current Ia and the phase voltage Ua are located on the same coordinate axis. Similarly, since the phase current Ic lags behind the line voltage Ucb, the corresponding JC is -30 degrees.

[0041] Based on the same principle, Figure 6 Another hexagonal diagram of three-phase voltage reverse phase sequence provided by the embodiment of the present invention can be referred to Figure 6 The control unit 21 can also generate a hexagonal diagram according to the phase sequence of the three-phase voltage and the angle between each phase voltage and the corresponding phase current in the three-phase voltage, which will not be described in detail here. It can be understood that Figure 6 This is only an example. Depending on the load characteristics of the electrical equipment and the specific angles of JA and JC, the hexagonal diagram finally generated will also be different. The corresponding hexagonal diagram can be generated according to the actual situation.

[0042] Optional, Figure 7 A schematic diagram of the structure of another power inspection device provided by an embodiment of the present invention is shown in FIG. Figure 7As shown, the host module 20 includes a control unit 21, and a display unit 22 and a storage unit 23 electrically connected to the control unit 21 respectively; the working parameters of the electrical equipment include the phase sequence of the three-phase voltage, the phase angle of each phase voltage in the three-phase voltage, and the angle between each phase voltage in the three-phase voltage and the corresponding phase current; the control unit 21 is used to determine the first wiring method of the electrical equipment according to the phase sequence of the three-phase voltage, the phase angle of each phase voltage in the three-phase voltage, and the angle between each phase voltage in the three-phase voltage and the corresponding phase current, and compare the first wiring method of the electrical equipment with the preset wiring method to determine the wiring result of the first wiring method; the display unit 22 is used to display the wiring result, and display the correct wiring method when the wiring result is determined to be wrong; the storage unit 23 is used to store the preset wiring method.

[0043] Specifically, the storage unit 23 stores preset wiring methods, including all wiring methods for different types of electrical equipment. It can be understood that there are correct wiring methods and incorrect wiring methods in the preset wiring methods. The storage unit 23 stores all possible wiring methods, so that the control unit 21 can compare the first wiring method with all preset wiring methods one by one after determining the first wiring method of the electrical equipment according to the phase sequence of the three-phase voltage, the phase angle of each phase voltage in the three-phase voltage, and the angle between each phase voltage in the three-phase voltage and the corresponding phase current, so as to determine which wiring method the current first wiring method is. At the same time, the display unit 22 will also display the first wiring method and the correct wiring method in the preset wiring method. If the first wiring method is completely consistent with the correct wiring method, it means that the current first wiring method is correct. If the first wiring method is completely different from the correct wiring method, the difference between the two will be used to quickly and accurately determine the cause of the abnormality in the actual wiring and display it, so that the technicians can conduct further investigation and maintenance.

[0044] Optionally, the electrical equipment includes three-phase four-wire electrical equipment and three-phase three-wire electrical equipment; according to the different wiring types of the electrical equipment, the storage unit 23 stores different numbers of preset wiring methods, among which the preset wiring methods corresponding to the three-phase four-wire electrical equipment include 96 types, and the preset wiring methods corresponding to the three-phase three-wire electrical equipment include 48 types.

[0045] Specifically, since there is a difference between positive phase sequence and reverse phase sequence in three-phase voltage, and the collected phase current may have positive and negative values, etc., all of these are caused by the different actual wiring methods of the electrical equipment. Therefore, the actual wiring methods of electrical equipment corresponding to different wiring types will also be different. In order to ensure that the control unit 21 can quickly and accurately locate the actual situation of the first wiring method, the storage unit 23 is required to store all types of preset wiring methods corresponding to three-phase four-wire electrical equipment or three-phase three-wire electrical equipment, so as to improve the intelligence and accuracy of the inspection device, thereby improving the application scope and inspection efficiency of the inspection device.

[0046] Optional, continue to refer to Figure 7 As shown, the host module 20 includes a control unit 21, and a display unit 22 and a storage unit 23 electrically connected to the control unit 21 respectively; the working parameters of the electrical equipment include load parameters, peak time periods, off-peak time periods, and power values ​​corresponding to the peak time periods and off-peak time periods respectively; the detection module 10 is also used to obtain current marketing data and send the marketing data to the storage unit 23 for storage, and the marketing data includes load parameters, peak time periods, off-peak time periods, and power values ​​corresponding to the peak time periods and off-peak time periods respectively; the control unit 22 is used to compare the load parameters, peak time periods, off-peak time periods, and power values ​​corresponding to the peak time periods and off-peak time periods respectively with the marketing data to determine whether they are consistent, and display them through the display unit 22.

[0047] The load parameters include the voltage and current of the load.

[0048] It is understandable that the marketing data is the data provided by the power supply company, including the load parameters corresponding to the power-consuming equipment, peak hours, off-peak hours, and the power values ​​corresponding to the peak hours and off-peak hours, and the power consumption during different hours. It is understandable that the power supply company finally calculates and statistics the power consumption of the load corresponding to the power-consuming equipment and the rates are determined based on the marketing data. At this time, if there is a discrepancy between the marketing data and the data actually collected by the power-consuming equipment, there will be deviations in the rates, etc.

[0049] In this way, the electricity consumption inspection device can obtain marketing data and pre-store it in the storage unit 23. After obtaining the working parameters of the electrical equipment, that is, the load parameters, peak time periods, off-peak time periods and the power values ​​corresponding to the peak time periods and off-peak time periods respectively, through the detection module 10, the control unit 21 compares the working parameters with the marketing data in the storage unit 23 one by one to determine whether they are consistent, and displays them through the display unit 22, which helps the technicians to further determine whether there are any abnormalities in the electrical equipment or marketing data.

[0050] For example, if in the same time period (including peak period and off-peak period), the total electric energy displayed by the electrical equipment is 10kwh, of which the electric energy in the peak period is 0kwh and that in the off-peak period is 10kwh, then the total electric energy recorded in the marketing data for this time period is also 10kwh, while the electric energy recorded for the peak period in this time period is 10kwh and that for the off-peak period is 0kwh. In this way, although the total electric energy has not changed, the marketing data mistakenly counts the electric energy in the off-peak period as the peak period, which leads to abnormal rates.

[0051] Optional, continue to refer to Figure 2 and Figure 7 As shown, the host module 20 includes an electrically connected control unit 21 and a display unit 22; the working parameters of the electric equipment include the time when the electric equipment meter cover is opened and the event record of the electric equipment, and the event record of the electric equipment includes the abnormal power consumption record; the control unit 21 is also used to determine whether there is electricity theft in the electric equipment based on the time when the electric equipment meter cover is opened and the abnormal power consumption record in the event record of the electric equipment, and send the abnormal power consumption record and the judgment result to the display unit 22; the display unit 22 is used to display the abnormal power consumption record and the judgment result.

[0052] Among them, the time when the meter cover of the electrical equipment is opened refers to the moment when the electrical equipment is opened.

[0053] Abnormal electricity consumption records include but are not limited to voltage loss records, current loss records or load curve abnormalities, etc. It can be understood that voltage loss means that the three-phase voltage or the voltage of one phase in the three-phase voltage suddenly disappears or becomes lower, etc.; current loss means that the three-phase current or the current of one phase in the three-phase current suddenly disappears or becomes lower, etc.; load curve abnormality refers to a sudden increase in load power or consumed electrical energy, etc.

[0054] Specifically, the control unit 21 can determine that there may be electricity theft during the period when the electric equipment opens the meter cover based on the acquired meter cover opening time and abnormal electricity consumption record of the electric equipment. At this time, the control unit 21 can further analyze whether there is electricity theft by comparing the changes in marketing data when the meter cover of the electric equipment is opened, and display the meter cover opening time of the electric equipment, abnormal electricity consumption record and analysis results through the display unit 23.

[0055] Optional, Figure 8 A schematic diagram of the structure of another power inspection device provided by an embodiment of the present invention is shown in FIG. Figure 8As shown, it also includes a voltage acquisition module 40 and a current acquisition module 50; the host module 20 includes a voltage input terminal V and a current input terminal I, the voltage input terminal V is electrically connected to the voltage acquisition module 40, and the current input terminal I is electrically connected to the current acquisition module 50; the voltage acquisition module 40 is used to acquire the three-phase voltage value of the electrical equipment; the current acquisition module 50 is used to acquire the three-phase current value of the electrical equipment; the host module 20 is also used to collect the three-phase voltage value and the three-phase current value of the electrical equipment through the voltage acquisition module 40 and the current acquisition module 50 respectively for further analysis and verification when it is determined that there is an abnormality in the electrical equipment.

[0056] Specifically, the voltage acquisition module includes but is not limited to voltage probes, and the current acquisition module includes but is not limited to current clamps. By electrically connecting the motor acquisition module to the power supply line, the three-phase voltage value can be acquired, and by setting the current clamp on the power supply line, the three-phase and three-phase current values ​​can be acquired. The host module 20 collects the three-phase voltage value and the three-phase current value of the electrical equipment according to the voltage acquisition module 40 and the current acquisition module 50 respectively, and further compares them with the working parameters of the electrical equipment obtained by the detection module 10 to further verify and analyze the abnormal causes of the electrical equipment, so as to improve the accuracy of the inspection device.

[0057] Optional, continue to refer to Figure 8 As shown, the host module includes a power supply unit 24, a human-computer interaction unit 25, etc. It can be understood that the power supply unit 24 is used to supply power to the host module, and the human-computer interaction unit 25 is convenient for technicians to operate the inspection device to improve the intelligence of the inspection device, thereby improving the work efficiency of the technicians.

[0058] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
