DETAILED DESCRIPTION

[0032] The technical solutions 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, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Embodiment 1, refer to Figure 1-10 A novel intelligent three-phase electric energy meter comprises a meter case 1 and an easy-to-disconnect wiring board 2. The two side walls of the meter case 1 are respectively connected to an indicating power supply 5 through two horizontal plates 4. The indicating power supply 5 is connected to a leveling U-shaped tube 7 for observing verticality through a guide rod 6. A conductive liquid is arranged in the leveling U-shaped tube 7.

[0034] Furthermore, two mounting pads 3 are fixedly connected to the two side walls of the case 1, the side wall of the case 1 is fixedly connected to the side wall of the horizontal plate 4, the bottom end of the horizontal plate 4 is fixedly connected to the top end of the indicating power supply 5 through a fixing rod, the indicating power supply 5 is electrically connected to the inside of the two sides of the leveling U-shaped tube 7 through the guide rod 6, the liquid level of the conductive liquid in the leveling U-shaped tube 7 is located at the same horizontal plane as the guide rod 6, and an indicator light 8 is provided on the guide rod 6;

[0035] It should be noted that: a mounting pad 3 on the electric energy meter case 1 is installed by screws, and then the entire electric energy meter case 1 is slightly deflected and adjusted along the screws at the mounting pad 3. At the same time, the indicating power supply 5 is started, and the indicating power supply 5 forms a circuit loop through the guide rod 6 and the conductive liquid in the leveling U-shaped tube 7. If the electric energy meter case 1 is kept in a vertical state during installation, the liquid levels on both sides of the conductive liquid in the leveling U-shaped tube 7 will be kept on the same horizontal plane and contact with both ends of the guide rod 6. The circuit loop is connected so that the indicator light 8 is on. If there is a tilt during installation, the liquid levels on both sides of the conductive liquid in the leveling U-shaped tube 7 will form a height difference, so that the circuit loop is disconnected and the indicator light 8 will go out.

[0036] A further advantage of adopting the above method is that it is possible to visually observe whether the installation of the electric energy meter is tilted based on the on and off status of the indicator light 8, thereby ensuring the verticality of the electric energy meter after installation, and also facilitating the subsequent maintenance and inspection by turning on the indicating power supply 5 to determine whether the electric energy meter is displaced or tilted.

[0037] Example 2, reference Figure 1-10 , a plurality of wiring terminals 9 are connected to the side wall of the easy-to-disconnect wiring board 2, a sealing cavity plate 10 is arranged outside the three wiring terminals 9, two mutually symmetrical regulating power supplies 11 are connected to the bottom side wall of the sealing cavity plate 10, the output end of the regulating power supply 11 is connected to an regulating ring 12 through a driving shaft, and the outer side wall of the regulating ring 12 is respectively connected to two compensation components through two compensation telescopic rods 13, and the compensation components are connected to a micro-electromagnetic plate 16, and a magnetic column 18 is arranged on one side of the micro-electromagnetic plate 16, and primary slide rails 17 and compound slide rails 21 are respectively arranged on both sides of the regulating power supply 11, and three wheel spoke components are arranged between the primary slide rail 17 and the compound slide rail 21;

[0038] Furthermore, the number of the plurality of wiring terminals 9 is eleven, and they are arranged in four groups. The number of the first three groups of wiring terminals 9 is three each, and the first three groups of wiring terminals 9 are respectively arranged in three sealing plates 10. The side wall of the bottom of the sealing plate 10 is fixedly connected to the end of the regulating power supply 11 through a right-angle rod, and the output end of the regulating power supply 11 is fixedly connected to the inner wall of the adjusting ring 12 through a driving shaft, and the outer wall of the adjusting ring 12 is fixedly connected to the fixed end of the compensation telescopic rod 13. The compensation component consists of a compensation rotating bead 14 and a ball bush 15. The piston rod end of the compensation telescopic rod 13 is fixedly connected to the side wall of the compensation rotating bead 14, the side wall of the compensation rotating bead 14 is rotatably connected to the inner wall of the ball bush 15, and the outer wall of the ball bush 15 is fixedly connected to the side wall of the micro electromagnetic plate 16. The initial slide rail 17 and the compound slide rail 21 The outer side walls are fixedly connected to the inner bottom side walls of the sealing cavity plate 10, the side walls of the two micro-electromagnetic plates 16 on one side are slidably connected to the inner side walls of the primary slide rail 17, and the side walls of the two micro-electromagnetic plates 16 on the other side are slidably connected to the inner side walls of the compound slide rail 21, the wheel spoke assembly is composed of an adjusting rack 19 and an adjusting gear ring 20, the adjusting rack 19 is meshed with the adjusting gear ring 20, the single adjusting rack 19 on one side is located on the middle inner side wall of the primary slide rail 17, and the two ends of the adjusting rack 19 are respectively fixedly connected to the two magnetic columns 18, the two adjusting racks 19 on the other side are located on the inner side walls at both ends of the compound slide rail 21, and the middle end of the adjusting rack 19 is fixedly connected to the magnetic column 18, and the side walls of the three adjusting racks 19 are respectively slidably connected to the inner side walls of the primary slide rail 17 and the compound slide rail 21;

[0039] It should be noted that: when the electric energy meter needs to be wired after installation, three-phase electricity is first connected, and the control button for connecting the three-phase electricity to the outside of the electric energy meter is turned on, which will start the regulating power supplies 11 in the three sealing chamber plates 10, and the two regulating power supplies 11 energize the two micro-electromagnetic plates 16 on one side of the primary slide rail 17, so that one of the two energized micro-electromagnetic plates 16 has the same magnetic pole as the adjacent end of the adjacent magnetic column 18, and the other has the opposite magnetic pole to the adjacent end of the adjacent magnetic column 18, then one end of the regulating rack 19 on the inner wall of the primary slide rail 17 is subjected to magnetic attraction, and the other end is subjected to magnetic repulsion, thereby pushing the regulating rack 19 to slide on the primary slide rail 17, and the micro-electromagnetic plate 16 is in the process of sliding. The rotation between the compensation bead 14 and the ball tile 15 is used to compensate for the angle, and the stretching of the compensation telescopic rod 13 is used to compensate for the distance. The sliding of the adjustment rack 19 will drive the adjustment toothed ring 20 to rotate, and the rotation of the adjustment toothed ring 20 will drive the prompt ring 22 to rotate together. The rotation of the prompt ring 22 will cause multiple driving rods 23 to rotate along with it. The change in the rotation angle of the driving rod 23 will cause the prompt plate 26 to rotate on the pin 24, thereby controlling the expansion of multiple closed prompt plates 26. When the staff connects the three-phase power wires, they can observe which three prompt plates 26 on the prompt rings 22 are open, and then use a screwdriver to connect the wires to the opened lower wiring terminals 9;

[0040] A further advantage of adopting the above method is that the three-phase power conductors can be quickly connected to the corresponding terminals of the electric energy meter by checking the opening state of the prompt plate 26 on the prompt ring 22.

[0041] Example 3, reference Figure 1-10 The wheel spoke assembly is connected with a reminder ring 22, the inner wall of the reminder ring 22 is provided with an annular groove, the inner wall of the annular groove is connected with a plurality of driving rods 23, the other end of the driving rod 23 is connected with a reminder plate 26, and the end surface of the reminder plate 26 is connected with an inner fixed ring 25 through a pin shaft 24;

[0042] Further, the end face of the adjusting gear ring 20 is fixedly connected to the end face of the prompt ring 22, the inner side wall of the prompt ring 22 is rotatably connected to one end of the driving rod 23, the other end of the driving rod 23 is rotatably connected to the bottom end face of the prompt plate 26, the prompt plate 26 is rotatably connected to the end face of the inner fixed ring 25 through the pin 24, and the end face of the inner fixed ring 25 is fixedly connected to the inner side wall of the annular groove starting from the inner side wall of the prompt ring 22;

[0043] It should be noted that: when the three mutual inductors need to be connected to the electric energy meter, the two micro-electromagnetic plates 16 on the compound slide rail 21 are energized by controlling the regulating power supply 11, so that the micro-electromagnetic plates 16 on the compound slide rail 21 magnetically attract the adjacent magnetic columns 18, thereby driving the adjustment rack 19 on the compound slide rail 21 to move, thereby driving the adjustment gear rings 20 on both sides to rotate, and unfolding the prompt plates 26 on the prompt rings 22 on both sides. After the wiring is completed, the prompt plates 26 are controlled to gather and close, which can protect the wiring part of the electric energy meter from dust, and avoid dust accumulation at the exposed wiring part, resulting in poor contact of the circuit;

[0044] A further advantage of adopting the above method is that it is convenient to quickly lock the wiring position when connecting the transformer to the electric energy meter, making the wiring sequence and wiring ideas of the entire electric energy meter clearer, and improving the speed and accuracy of the overall wiring of the electric energy meter.

[0045] When the present invention is used, a mounting pad 3 on the electric energy meter case 1 is installed by screws, and then the entire electric energy meter case 1 is slightly deflected and adjusted along the screws at the mounting pad 3. At the same time, the indicating power supply 5 is started, and the indicating power supply 5 forms a circuit loop through the guide rod 6 and the conductive liquid in the leveling U-shaped tube 7. If the electric energy meter case 1 is kept in a vertical state during installation, the liquid levels on both sides of the conductive liquid in the leveling U-shaped tube 7 will be kept on the same horizontal plane and contact the two ends of the guide rod 6. The circuit loop is connected so that the indicator light 8 lights up. If there is a tilt during installation, the liquid levels on both sides of the conductive liquid in the leveling U-shaped tube 7 will form a height difference, so that the circuit loop is disconnected and the indicator light 8 will go out. In this way, it is possible to intuitively observe whether the electric energy meter is tilted according to the on and off status of the indicator light 8, thereby ensuring the verticality of the electric energy meter after installation. It is also convenient to judge whether the electric energy meter has position displacement or tilt by turning on the indicating power supply 5 during subsequent maintenance and inspection.

[0046] When the electric energy meter needs to be wired after installation, three-phase electricity is first connected. When the control button for connecting the three-phase electricity outside the electric energy meter is turned on, the regulating power supplies 11 in the three sealing chamber plates 10 are turned on. The two regulating power supplies 11 energize the two micro-electromagnetic plates 16 on one side of the primary slide rail 17, so that one of the two energized micro-electromagnetic plates 16 has the same magnetic pole as the adjacent end of the adjacent magnetic column 18, and the other is opposite to the adjacent end of the adjacent magnetic column 18. Then, one end of the regulating rack 19 on the inner wall of the primary slide rail 17 is subjected to magnetic attraction, and the other end is subjected to magnetic repulsion, thereby pushing the regulating rack 19 to slide on the primary slide rail 17. During the sliding process of the micro-electromagnetic plate 16, the rotation between the compensation bead 14 and the ball shoe 15 is used to compensate for the angle. , the stretching of the compensation telescopic rod 13 is used to compensate for the distance, the sliding of the adjustment rack 19 will drive the adjustment toothed ring 20 to rotate, the rotation of the adjustment toothed ring 20 will drive the prompt ring 22 to rotate together, the rotation of the prompt ring 22 will cause multiple driving rods 23 to rotate along, then the change in the angle of rotation of the driving rod 23 will cause the prompt plate 26 to rotate on the pin 24, thereby controlling the expansion of multiple closed prompt plates 26, then when the staff connects the three-phase power wires, they can observe which three prompt plates 26 on the prompt rings 22 are open, and then use a screwdriver to connect the wires to the opened lower wiring terminals 9, so that the three-phase power wires can be quickly connected to the corresponding terminals of the electric energy meter through the open state of the prompt plate 26 on the prompt ring 22;

[0047] When it is necessary to connect three mutual inductors to the electric energy meter, the two micro-electromagnetic plates 16 on the compound slide rail 21 are energized by controlling the regulating power supply 11, so that the micro-electromagnetic plates 16 on the compound slide rail 21 magnetically attract the adjacent magnetic columns 18, thereby driving the adjustment rack 19 on the compound slide rail 21 to move, thereby driving the adjustment gear rings 20 on both sides to rotate, and unfolding the prompt plates 26 on the prompt rings 22 on both sides. After the wiring is completed, the prompt plates 26 are controlled to gather and close, which can protect the wiring parts of the electric energy meter from dust, avoid dust accumulation at the exposed wiring parts, and cause poor contact of the circuit. In this way, when the mutual inductor is connected to the electric energy meter, the wiring position can be quickly locked, making the wiring sequence and wiring ideas of the entire electric energy meter clearer, and improving the speed and accuracy of the overall wiring of the electric energy meter.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
