[0002] Smart meters are one of the basic data acquisition devices in smart grids (especially smart distribution networks). They are responsible for the collection, metering, and transmission of raw electrical energy data, and are the foundation for information integration, analysis, optimization, and information display. In addition to the basic electricity metering function of traditional electricity meters, they also have intelligent functions such as bidirectional multi-rate metering, user-end control, bidirectional data communication with multiple data transmission modes, and anti-theft features. Because smart meters play an important role, they require frequent operation and maintenance, and meter rotation is an important part of their operation and maintenance.

When adjusting, loosen the positioning bolt 174 to adjust the position of the slide 173. After adjusting to the appropriate position, tighten the positioning bolt 174 again to fix the position of the slide 173. Then, adjust the position and angle of the connecting piece on the electricity meter junction box according to the position and angle of the connecting piece. When adjusting the angle, slide the slide rod 179 in the arc groove 178 until it reaches the appropriate position.

After adjusting to the appropriate position, the connecting mechanism 17 can be fixedly connected to the electricity meter junction box by the fixing bolt 177 for subsequent meter replacement operations. This allows the connection mechanism 17 to be installed on junction boxes of electricity meters of different sizes, expanding the scope of application of the device, reducing the burden on personnel, improving the efficiency of meter replacement, and making it convenient to use.

[0028] Example 1 (Meter replacement operation without power interruption using connecting cable 19, piercing splitter 18, and wiring device 3): When replacing the meter, first install a new energy meter on the new meter connection post 6 and fix the new meter through the new meter connection head 8. Then connect the body 181 of the split-type piercing splitter 18 to the main line of the energy meter with a diameter of 2-5mm. First, put half of the body 181 with the conductive plate 184 on the main line of the energy meter so that it is inside the wire hole 183 of the energy meter. Then connect the other half of the body 181 with the half of the body 181 with the conductive plate 184. At this time, the piercing head 185 pierces the insulation layer of the main line and conducts through the wire of the main line to realize the connection function with the main line. Then unscrew the protective cover 196 and screw the plug handle 195 into the connection hole 182 so that the wiring plug 1951 contacts the conductive plate 184. At this time, the wiring plug 1951 forms a circuit with the main line of the power meter. Then connect the wiring head 192 to the wiring device 3. At this point, press the start switch 15. The button indicator light will illuminate. After confirming that the electricity meter is working normally, proceed with the subsequent meter replacement work. After pressing the start switch 15, the voltage and current indicator lights and the on / off indicator lights of the new meter position will display normally. If they do not display normally, consider whether the electricity meter connection is reliable and whether the puncture is reliable. If necessary, restore the CT terminal short circuit caused by the CT high voltage through the CT reset button. After confirming that the electricity meter is working normally, proceed with the subsequent meter replacement work. Then, remove the electricity meter main line with a diameter of 2-5mm from the old electricity meter and put the protective sleeve 196 on the exposed main line. Finally, screw the protective sleeve 196 onto the wire hole 183 to fix the protective sleeve 196. At this point, the old electricity meter can be installed on the old meter connection post 7 and fixed with the old meter connection head 9. Press the old meter power button 13 to confirm that the old meter position is working normally. Release the new meter power button 10. At this time, the on / off indicator light will display normally. Then, remove the new electricity meter from the new meter connection post 6 and install the new electricity meter in the meter box. When installing the new electricity meter, remove the protective cover 196 and connect the main line to the new electricity meter. The new electricity meter will work normally. At this time, the old meter power-on button 13 and the start switch 15 on the wiring device 3 will pop up respectively, and the power-on meter reading button 14 will be pressed. The reading of the old meter will be read on the non-destructive high voltage uninterrupted power connection device 3. After the meter reading is completed, the power-on meter reading button 14 will be disconnected, the old meter will be removed from the old meter connection post 7 of the wiring device 3, and then the plug handle 195 will be removed from the connection hole 182. The main body 181 can then be removed from the main line, so that the connection line 19 is disconnected from the wiring device 3. Install the end cap of the electricity meter and affix a lead seal to complete the meter replacement process.

[0029] Example 2 (When replacing an energy meter with an electricity meter junction box using the connecting mechanism 17, connecting component 20 and connecting wire 19): When replacing the meter, first install a new energy meter on the new meter connection post 6, and then fix the new meter in place using the new meter connection head 8. At this time, the width of the electricity meter junction box should be considered (e.g., ...). Figure 9 As shown in the figure, a is the electricity meter junction box and b is the screw hole. Adjust the width of the connecting mechanism 17 and adjust the extension length of the conductive head 2010 according to the position of the connecting piece inside the electricity meter junction box. Then, the connecting mechanism 17 can be threaded into the screw hole by the fixing bolt 177, and then the connecting mechanism 17 can be fixedly connected to the electricity meter junction box. Then, adjust the spacing between each connecting component 20 so that each connecting component 20 corresponds to the connecting piece of one circuit of the electricity meter junction box (the connecting piece is existing technology and is not shown in the figure, so it will not be described in detail). At this time, the conductive head 2010 contacts the connecting piece. Then, the plug handle 195 can be threaded into the plug hole 207, and then the terminal 192 can be connected to the wiring device 3. At this point, press the start switch 15. The button indicator light will illuminate. After confirming that the electricity meter is working normally, proceed with the subsequent meter replacement work. After pressing the start switch 15, the voltage and current indicator lights and the on / off indicator lights of the new meter position will display normally. If they do not display normally, consider whether the electricity meter connection is reliable and whether the puncture is reliable. If necessary, restore the CT terminal short circuit caused by the CT high voltage through the CT reset button. After confirming that the electricity meter is working normally, proceed with the subsequent meter replacement work. Then disconnect the old electricity meter from the electricity meter junction box. At this point, the old electricity meter can be installed on the old meter connection post 7 and fixed with the old meter connection head 9. Press the old meter power button 13 to confirm that the old meter position is working normally. Release the new meter power button 10. At this time, the on / off indicator light will display normally. Then, remove the new electricity meter from the new meter connection post 6 and install the new electricity meter in the meter box. When installing the new electricity meter, make sure that the electricity meter junction box is connected to the new electricity meter through a wire. The new electricity meter will work normally. At this time, the old meter power-on button 13 and the start switch 15 on the wiring device 3 are respectively popped up, and the power-on meter reading button 14 is pressed. The reading of the old meter is read on the non-destructive high voltage uninterrupted power connection device 3. After the meter reading is completed, the power-on meter reading button 14 is popped up, the old meter is removed from the old meter connection post 7 of the wiring device 3, and the connection mechanism 17 is removed, so that the connection line 19 is disconnected from the wiring device 3 (it should be noted that when the plug handle 195 is inserted into the plug hole 207, the neutral wire of the electricity meter junction box is connected first and then the phase wire is connected. When disconnecting, the phase wire is disconnected first and then the neutral wire is disconnected). Install the end cap of the electricity meter and affix a lead seal to complete the meter replacement process.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
