Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] The present application provides a kind of not power meter change support matched anti-overheating electric energy metering device as shown in Figures 1-3 The present application provides a kind of not power meter change support matched anti-overheating electric energy metering device as shown in, including flow diverter 1, meter module 2, large current double conductor wiring, meter module 2 is equipped with inlet and outlet socket 21, flow diverter 1 includes shell 11, shell 11 is equipped with two jacks 12, respectively with the wiring plug post of electric energy meter corresponding, two jacks 12 between respectively two corresponding conductive spring 13 are installed, conductive spring 13 is respectively connected with two conductive connecting pieces 14, conductive connecting piece 14 is fixedly connected with shell 11, shell 11 is equipped with plug-in cover 15, plug-in cover 15 is installed with the extrusion rod 16 that can move up and down, when extrusion rod 16 moves downward, it is inserted between conductive spring 13, so that conductive spring 13 is tightly attached to the wiring plug post of electric energy meter, plug-in cover 15 is installed with switch 17, switch 17 is fixedly connected with the top of extrusion rod 16; Further, the two ends of the large current double conductor wiring are respectively connected with the inlet and outlet socket 21 of the meter module 2 and the two conductive connecting pieces 14 of the flow diverter 1. Further, the meter module 2 integrates electric energy metering, active metering, voltage display, current monitoring, power and power factor measurement functions, the accuracy level is first class, the electric quantity can be cleared, the power-off function can be realized, and the data can be viewed through the mobile phone through the WIFI signal, which is convenient for the meter changing personnel to save data. The function of the extrusion rod 16 is that, since the conductive spring 13 of the flow diverter 1 is not tightly attached to the wiring plug post of the electric energy meter, when the extrusion rod 16 is inserted between the conductive spring 13, the conductive spring 13 is extruded to tightly attach to the plug post, reducing the conductive resistance and avoiding overheating. In the embodiments of the present application, first, when the electric energy meter replacement operation is performed on the centralized meter box, the staff will install the not power meter change support in the appropriate position in the meter box, carefully check whether the installation is firm and whether the wiring is correct, fix the support in the specified position of the meter box according to the operation procedures using professional tools, and strictly perform the wiring according to the wiring diagram to ensure that each connection point is firm and reliable. Then, the flow diverter 1 is fixed by screwing the screw fixing point of the plug-in cover 15 with the uninterrupted power meter changing support. During the fixing process, the staff will use a torque wrench to tighten the screw to the specified torque value to ensure the stability of the relative position between the two and reliable connection. At the same time, the plug 12, the conductive spring 13 and the metering module 2 of the flow diverter 1 are comprehensively checked to see if they are intact, and the connection wires between the components are normal. Finally, the metering module 2 is initialized and the power is cleared to prepare for accurate metering in the future; Two flow diverters 1 are used, one of which is connected with the live line connection in and out of the plug-in column of the electric energy meter, and the other is connected with the zero line connection in and out of the plug-in column of the electric energy meter. During the connection process, the staff will ensure that the plug hole of the flow diverter 1 is tightly matched with the line plug-in column of the electric energy meter to ensure good electrical connection. The metering module 2 is provided with a live line connection in and out of the plug-in column and a zero line connection in and out of the plug-in column, and two sets of large current double conductor wires are used to adapt the connection between the two flow diverters 1 and the metering module 2. The two ends of the large current double conductor wire are connected with the in and out socket of the metering module 2 and the two conductive connectors 14 of the flow diverter 1 respectively to ensure stable transmission of the current signal; The flow diverter 1 collects the voltage and current signals in the meter changing process in real time. The external wire of the flow diverter 1 serves as the electrical connection interface between the uninterrupted power meter changing support, and the voltage and current signals of the power supply live line and zero line in the process of changing the electric energy meter are introduced into the flow diverter 1. The conductor is connected with the power supply live line and zero line in and out terminal of the uninterrupted power meter changing support, and the current signal introduced by the external wire in the process of changing the electric energy meter is accurately collected and conducted and distributed in the flow diverter 1. The large current double conductor wire ensures that the current signal can be accurately and stably transmitted to the metering module 2 in the process of changing the electric energy meter; The three single-phase metering modules in the metering module 2 monitor and meter the three-phase current in real time, and calculate the active power, voltage, current, power and power factor according to the received voltage and current signals. The metering module 2 displays the calculated data on the display screen in real time, and transmits the data to the paired mobile phone device through the WIFI signal. In the process of changing the meter, if abnormal fluctuations of the current or power of a phase are found, the operator can check the data and make a preliminary judgment through the mobile phone to decide whether further inspection or measures are needed; After the replacement of the electric energy meter, the newly replaced electric energy meter is normally connected to the circuit. At this time, the metering module 2 continues to monitor for a period of time to ensure that the new electric energy meter is working properly. After the completion of the meter replacement work, the metering module 2 continues to monitor the operating state of the new electric energy meter, including voltage, current, power and other parameters, to ensure that the new electric energy meter can operate stably; At the same time, record the initial data after the completion of the meter replacement, check and calibrate the electric quantity data recorded by the metering module during the meter replacement process with the initial reading of the new electric energy meter, to ensure the continuity and accuracy of electric quantity measurement. The staff will record the relevant data in detail, including the change curve of active electric quantity, voltage, current, power and power factor and other parameters, as well as the meter replacement time, operator and other related information, which provides an important reference basis for subsequent electric energy management, equipment maintenance and performance evaluation.

[0025] During the entire meter replacement process, the user's electricity use is not affected, greatly improving the user experience and reducing the inconvenience and loss caused by power failure. Whether it is daily life electricity for residential users, or production and operation electricity for commercial and industrial users, it can be continuously and stably supplied, avoiding problems such as production interruption, equipment damage, data loss and other problems caused by power failure. For example, for hospitals, data centers and other places with extremely high requirements for power supply, the uninterrupted meter replacement technology can ensure the uninterrupted operation of key equipment, ensuring the continuity of medical services and data processing; The current diverter 1 can accurately collect signals, and the metering module 2 can accurately calculate various electric energy parameters and transmit data through the display screen and WIFI, realizing real-time and accurate measurement. This not only can avoid the electric fee dispute caused by inaccurate electric quantity measurement during the meter replacement process, but also provides detailed and reliable electric energy use data for electric power enterprises. Electric power enterprises can accurately manage electric quantity, electric fee settlement, optimize electric power distribution, improve the operation efficiency of electric power system and reduce economic losses caused by inaccurate measurement based on these data. Through analysis of a large amount of meter replacement data, electric power enterprises can find the electricity use rules and potential problems in some areas, and timely adjust the electric power supply strategy to improve the utilization efficiency of electric power resources; During the meter replacement process, if abnormal fluctuations in current or power of a phase are found, the operator can check the data through the mobile phone and make a preliminary judgment to decide whether further inspection or measures are needed. This helps to quickly locate and solve potential power faults, improve the reliability and stability of the power system. At the same time, the measurement data during the meter replacement process are sorted and archived, including the change curve of active electric quantity, voltage, current, power and power factor and other parameters, as well as the meter replacement time, operator and other related information, which provides an important basis for subsequent equipment maintenance and performance evaluation. Through analysis of these data, electric power enterprises can find potential problems of equipment in advance, arrange maintenance and repair work in advance, prolong the service life of equipment and reduce the equipment failure rate.

[0026] Please refer to Figures 1-2 In one embodiment of the present application, the inner part of the current diverter 1 is provided with two annular gaskets 19 at the upper end of the extrusion rod 16, and the annular gasket 19 at the lower end is fixedly installed on the shell 11. The annular gasket 19 at the upper end is fixedly connected with the extrusion rod 16, and the spring 18 is fixedly connected between the two annular gaskets 19 and is sleeved on the outer side of the extrusion rod 16; In the embodiment of the present application, when the wiring post of the electric energy meter is inserted into the insertion hole 12, in order to make the conductive reed 13 tightly contact the wiring post of the electric energy meter, the extrusion rod 16 moves downward to extrude the conductive reed 13 on both sides while the switch 17 is turned on. At this time, the switch 17 is clamped, the spring 18 is compressed, and the conductive reed 13 is tightly attached to the wiring post of the electric energy meter. When it is needed to release the conductive reed 13 to disconnect the circuit, the switch 17 is actuated, and under the rebounding action of the spring 18, the switch 17 returns to the initial position. The conductive reed 13 is disconnected from the wiring post of the electric energy meter, and the circuit is disconnected.

[0027] The design of the annular gasket 19 and the spring 18 structure can make the conductive reed 13 tightly contact the wiring post by extruding the conductive reed 13 with the extrusion rod 16 when the wiring post of the electric energy meter is inserted into the insertion hole 12. This tight contact greatly reduces the contact resistance, ensures good electrical connection between the electric energy meter and the current diverter, and avoids overheating. In actual electric energy meter replacement operations, stable electrical connection can ensure that the voltage and current signals are accurately transmitted from the electric energy meter to the current diverter, providing a reliable data basis for subsequent metering and monitoring, avoiding unstable or interrupted signal transmission due to poor contact, and thus affecting the normal operation of the entire metering device; The extrusion of the conductive reed 13 by the extrusion rod 16 is realized at the same time as the circuit is turned on by pressing the switch 17, which is simple and convenient. The operator only needs one action to complete the circuit connection and the compression of the conductive reed 13, improving the work efficiency. Moreover, when it is needed to disconnect the circuit, the switch is actuated, the switch returns to the initial position by the rebounding action of the spring 18, the conductive reed 13 is disconnected from the wiring post, and the circuit is disconnected. This design makes the on-off control of the circuit very convenient, and the operator can easily operate according to actual needs. After the replacement of the electric energy meter is completed, the connection between the current diverter and the old meter can be quickly disconnected, and the new meter can be connected; The buffering effect of the spring 18 can effectively prevent the extrusion rod 16 from causing excessive impact and damage to the conductive reed 13 and other components. In repeated electric energy meter replacement operations, the spring 18 can absorb the energy during the movement of the extrusion rod 16, reducing the wear and fatigue between components. When the operator presses the switch, the spring can buffer the impact force of the extrusion rod, preventing the conductive reed from deforming or being damaged due to sudden excessive pressure, thereby prolonging the service life of the current diverter, reducing the maintenance cost of the equipment, and ensuring the long-term stable operation of the entire metering device.

[0028] See also Figure 2 In one embodiment of the present invention, the end of the extrusion rod 16 close to the conductive spring 13 is wedge-shaped, and the side surfaces of the two conductive springs 13 close to the extrusion rod 16 are smooth arc surfaces; In this embodiment of the present invention, when the electricity meter's terminal plug is inserted into the receptacle 12 of the current diverter 1, the operator presses the switch 17. This action causes the squeeze rod 16 to move downward. Because the end of the squeeze rod 16 near the conductive spring 13 is wedge-shaped, the wedge-shaped end gradually inserts between the two conductive springs 13 during its downward movement. Because the sides of the conductive springs 13 near the squeeze rod 16 are smooth, the wedge-shaped end can smoothly squeeze the two conductive springs 13 toward each other. As the squeeze rod 16 continues to move downward, the conductive springs 13 are gradually pressed against the electricity meter's terminal plug. At this point, the spring 18 is compressed, and the switch 17 is locked, maintaining the circuit in the on state. In actual installation, after the operator inserts the electricity meter's terminal plug into the receptacle 12, they steadily press the switch 17. It can be clearly seen that the squeeze rod 16 moves downward, causing the conductive spring 13 to cling tightly to the terminal plug, ensuring a good electrical connection.

[0029] The wedge-shaped design of the extrusion rod 16, combined with the smooth curved surface of the conductive spring 13, ensures that the conductive spring 13 is evenly stressed when squeezed, tightly fitting the terminal of the energy meter. This tight and uniform contact effectively reduces contact resistance, minimizing energy loss and heat generation at the connection point. In a high-load factory environment, the low contact resistance ensures efficient energy transfer between the energy meter and the diverter 1, improving metering accuracy, while avoiding local overheating caused by poor contact and enhancing the safety and stability of equipment operation. The wedge-shaped squeeze rod 16 allows the operator to apply only minimal force when pressing the switch 17 to tightly squeeze the conductive spring 13 against the meter's terminal. Furthermore, the smooth curved surface of the conductive spring 13 makes the squeezing process smoother, reducing any lag. This allows the operator to connect and disconnect the flow diverter 1 from the meter more easily and quickly, improving meter replacement efficiency and reducing labor intensity. Uniform force and a smooth extrusion process reduce wear on the conductive spring 13 and the extrusion rod 16. During repeated meter replacement operations, this design effectively prevents fatigue deformation or damage to the conductive spring 13 due to excessive local force, while also reducing wear on the extrusion rod 16. For example, long-term practical application testing has shown that the current diverter 1 using this design maintains good performance of the conductive spring 13 and the extrusion rod 16 after multiple meter replacement operations, reducing the frequency of equipment repair and replacement, lowering equipment maintenance costs, and extending the overall service life of the equipment. Stable electrical connections and reliable operation are crucial factors in ensuring the stable operation of the entire non-stop meter replacement system. The optimized design of the extrusion rod 16 and the conductive reed 13 ensures the accuracy and stability of signal acquisition during the meter replacement process. Metering module 2 enables precise metering and data transmission based on stable signal input, effectively improving the stability of the entire system. This is crucial for the reliable operation of the power system. Whether it's residential or industrial electricity production, accurate energy metering and a stable power supply are guaranteed, avoiding power management issues caused by metering device failure or instability.

Step S2: When the electric energy meter is replaced, two current diverters are used, one of which is adapted to be connected to the live wire inlet and outlet plugs of the electric energy meter, and the other is adapted to be connected to the neutral wire inlet and outlet plugs of the electric energy meter.

Two sets of high-current double-conductor wiring are used to adapt and connect the two current diverters to the metering module; Step S3: The current diverter collects voltage and current signals in real time during the meter replacement process, and transmits these sampled signals to the metering module through a high-current double-conductor connection; Step S4: The three single-phase metering modules in the metering module respectively monitor and measure the three-phase current in real time, and calculate the active power, voltage, current, power and power factor parameters using internal algorithms based on the received voltage and current signals; Step S5: The metering module displays the calculated data on the display screen in real time and transmits the data to the paired mobile phone via Wi-Fi signal. The meter replacement personnel can view the metering data on the mobile phone on site and save the data for subsequent analysis and statistics. Furthermore, after the replacement of the electric energy meter is completed, the newly replaced electric energy meter is normally connected to the circuit. At this time, the metering module continues to monitor for a period of time to ensure that the new electric energy meter is working properly, and at the same time records the initial data after the replacement of the meter is completed. The electric energy data recorded by the metering module during the replacement process is compared and calibrated with the initial reading of the new electric energy meter to ensure the continuity and accuracy of electric energy measurement; In the embodiment of the present application, the metering method realizes non-power-off meter replacement, and the user's power consumption is not affected during the whole meter replacement process, greatly improving the user experience and reducing the inconvenience and loss brought to the user due to power failure. The drain 1 accurately collects signals, the metering module 3 accurately calculates various electric energy parameters, and transmits data through the display screen 32 and WIFI, realizing real-time and accurate metering. This can not only avoid the electric fee disputes caused by inaccurate electric quantity metering during meter replacement, but also provide detailed and reliable electric energy use data for power enterprises.

[0031] The working principle of the present application: the present application realizes non-power-off meter replacement and accurate metering through the cooperative work of the non-power-off meter replacement support, the drain 1, the large-current double-conductor wiring and the metering module 2. First, install the non-power-off meter replacement support and check the related equipment, the drain 1 collects voltage and current signals by its structure, and transmits the signals to the metering module 2 through the large-current double-conductor wiring, the single-phase metering module of the metering module 2 calculates the three-phase current related parameters, the data is displayed in real time and can be transmitted to the mobile phone through WIFI.
