Description

Technical Field

[0001] The present invention relates to the technical field of electric energy metering boxes, and in particular to a multi-module integrated electric energy metering box. Background Art

[0002] The smart grid is an intelligent upgrade of the traditional power system. Based on the physical power grid, it integrates information technology, communications technology, sensing technology, and automated control technology. It uses sensors throughout the grid (such as smart meters and line monitoring devices) to collect real-time data. Using algorithms, it quickly locates faults (such as line shorts), automatically isolates faulty areas, and restores power to non-faulty areas, thus reducing power outages.

[0003] Traditional power grid metering relies on single-function mechanical meters or simple electronic meters, which can only achieve "electricity statistics"; while smart grids require metering equipment to assume more complex roles, such as real-time monitoring of multi-dimensional data such as voltage, current, power, and power factor to provide a basis for grid scheduling (such as load forecasting). It integrates various traditionally dispersed functional units such as electricity metering, protection, control, monitoring, and communication into a unified box through modular design.

[0004] Among them, the patent with announcement number CN212462500U discloses an electric energy metering box, including: a panel; an installation box, including two box bodies that are spliced ​​together, and the two box bodies are respectively provided with a snap-on structure, wherein at least one box body is formed with a through groove extending along the splicing direction, and the through groove passes through the splicing side of the box body. The through groove allows a connecting piece to pass through to install the panel on an external component.

[0005] When this structure is in use, the installation box is divided into two separable boxes, and a through groove is provided in the box. After the meter box is installed on the external component, the panel can be fixed by the connecting piece, and the box to be removed can be removed along the splicing direction. There is no need to interrupt the circuit of the electrical components on the panel when removing and installing the box. However, this structure is not easy to quickly convert and cut off the current by fixing it with the connecting piece, and the function of combing different currents cannot be achieved.

[0012] Optionally, in a possible embodiment, a limiting plate is respectively provided at one end of the first cross bar and the second cross bar located outside the protective tube, a second offset groove is opened on the outside of the protective tube, and the limiting plate is embedded in the second offset groove.

[0013] Optionally, in a possible embodiment, a deflection member is hinged at one end of the diverter, and a handle is hinged at the end of the deflection member away from the diverter.

[0014] Optionally, in a possible embodiment, a base plate is installed at the bottom of the protective tube by bolts, and an electrode is provided on the base plate. The top of the electrode passes through the second electromagnet, the first electromagnet and the center tube in sequence and extends to the top of the box, and the electrode transmits current to the shunt through the reinforced conductive ring.

[0015] Optionally, in a possible implementation manner, a cabinet door is hingedly connected to one side of the surface of the box body, and a guardrail is embedded in the top of the box body.

[0016] The present invention has the following advantages:

[0017] 1. This invention utilizes the repulsive nature of like-pole interactions between the first and second electromagnets, driving them axially along the central tube through electromagnetic force. Combined with the linkage structure of the first and second crossbars and the top bar, it precisely controls the contact state between the shunt and the elastic conductive pins, achieving automatic current splitting and path switching. Furthermore, the wire connection between the current converter and the shunt allows for real-time conversion of different current parameters, facilitating rapid adaptation to multiple current scenarios.

[0018] 2. The elastic conductive pin of the present invention is embedded in the top of the inner cavity of the central tube. When the diverter is adjusted by the deflection member and the handle, it can closely contact the elastic conductive pin, using elastic deformation to maintain conductive stability and avoid measurement errors caused by poor contact. Strengthening the coordination between the conductive ring and the electrode further improves the current transmission efficiency and reduces energy loss.

[0019] 3. The sliding connection design between the first and second triangular slots and the crossbar of the present invention enables the electromagnet to synchronously drive the crossbar to move laterally when it is displaced. Through the inclined transmission of the inclined slots and the top rod, combined with the elastic support of the spring, the displacement of the electromagnet can be precisely controlled. The embedded structure of the limit plate and the second offset slot prevents excessive displacement of the crossbar, ensuring the reliability of the linkage of each module and further ensuring the stability of current transmission.

[0020] In summary, by leveraging the repulsion between like-pole pairs of the first and second electromagnets to drive their axial displacement along the central tube, and in conjunction with the linkage structure of the first and second crossbars and the top rod, the contact state between the shunt and the elastic conductive pins can be precisely controlled, enabling automatic current splitting and path switching. Furthermore, the wire connection between the current converter and the shunt allows for real-time conversion of different current parameters, facilitating rapid adaptation to multiple current scenarios.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] As attached Figure 1-9 The multi-module integrated electric energy meter box shown in the figure uses a control component installed on the box body 1. The first electromagnet 3 and the second electromagnet 4 are driven by electromagnetic force to move axially along the central tube 2. In conjunction with the linkage structure of the first crossbar 11, the second crossbar 12, and the top rod 14, the contact state between the shunt 8 and the elastic conductive pin 7 can be precisely controlled to achieve automatic current separation and path switching. The linkage structure of the first crossbar 11, the second crossbar 12, and the top rod 14 can precisely control the contact state between the shunt 8 and the elastic conductive pin 7, achieving automatic current separation and path switching. At the same time, the current inverter 25 is connected to the wires of the shunt 8 to convert different current parameters in real time, making it easy to quickly adapt to multiple current scenarios. The specific structural configuration of the component is as follows.

[0034] The regulating component includes a protective tube 2 arranged in the box body 1, a first electromagnet 3 is arranged in the middle of the protective tube 2, a second electromagnet 4 is arranged at the bottom of the first electromagnet 3, a reinforcing conductive ring 5 is arranged on the top of the first electromagnet 3, and the magnetic poles of the first electromagnet 3 and the second electromagnet 4 at one end close to each other are the same.

[0035] As attached Figure 3 、 5 As shown in Figures 7, 8 and 9, when the second electromagnet 4 and the first electromagnet 3 are connected to current, the magnetic poles of the first electromagnet 3 and the second electromagnet 4 are the same, generating a repulsive force, which enables the second electromagnet 4 and the first electromagnet 3 to move up and down along the axial direction of the protective tube 2 inside the protective tube 2.

[0036] A central tube 6 is provided at the top of the reinforcing conductive ring 5, and a number of elastic conductive pins 7 are distributed on the outside of the central tube 6. A shunt 8 is provided on the top of each elastic conductive pin 7. The bottom end of the elastic conductive pin 7 is embedded in the top of the inner cavity of the protective tube 2, and a number of shunts 8 are hinged on the outside of the central tube 6, which are respectively located at the top of the corresponding elastic conductive pin 7.

[0037] As attached Figure 5 and 9 As shown, when the shunt 8 deflects outside the central tube 6 , it can come into contact with the elastic conductive pin 7 , so that the elastic conductive pin 7 can transfer the current to the shunt 8 for shunt transmission.

[0038] A first cross bar 11 is provided on one side of the first electromagnet 3, and a second cross bar 12 is provided on one side of the second electromagnet 4. The first cross bar 11 and the second cross bar 12 are both placed horizontally on the protective tube 2. The bottom of the first cross bar 11 and the top of the second cross bar 12 are respectively provided with an inclined groove 13, and a push rod 14 is slidably connected in each inclined groove 13, and a spring 23 is embedded between the two push rods 14.

[0039] As attached Figure 3 、 5 As shown in Figures 7, 8 and 9, when the first cross bar 11 and the second cross bar 12 move laterally on the protective tube 2 respectively, the inclined groove 13 on the first cross bar 11 contacts the top rod 14 at the bottom of the first cross bar 11, thereby causing the top rod 14 to move downward to compress the spring 23. The spring 23 drives the top rod 14 at the top of the second cross bar 12 to move downward and contact the inclined groove 13 opened on the second cross bar 12, thereby enabling the second cross bar 12 to move laterally on the protective tube 2.

[0040] A plurality of first triangular slots 15 are formed on the outer side of the first electromagnet 3 , a plurality of second triangular slots 16 are formed on the outer side of the second electromagnet 4 , and each first cross bar 11 and second cross bar 12 are slidably connected to the corresponding first triangular slot 15 and second triangular slot 16 .

[0041] As attached Figure 7 、 8 As shown in Figure 9, when the second electromagnet 4 and the first electromagnet 3 are displaced along the axial direction of the protective tube 2, the first electromagnet 3 contacts the first cross bar 11 through the first triangular groove 15, and the second electromagnet 4 contacts the second cross bar 12 through the second triangular groove 16, thereby driving the first cross bar 11 and the second cross bar 12 to move laterally on the protective tube 2, so that the spring 23 is compressed through the inclined groove 13 and the top rod 14 when the first cross bar 11 and the second cross bar 12 move laterally, so that the second cross bar 12 and the first cross bar 11 can respectively lift the second electromagnet 4 and the first electromagnet 3, thereby avoiding the first electromagnet 3 and the second electromagnet 4 being in an elastically supported state after the first electromagnet 3 and the second electromagnet 4 are powered on, and also facilitating that the magnetic poles of the first electromagnet 3 and the second electromagnet 4 are the same after the first electromagnet 3 and the second electromagnet 4 are powered on to generate a repulsive force, driving the first electromagnet 3 and the second electromagnet 4 to control the displacement stroke.

[0042] A limiting plate 17 is respectively provided at one end of the first cross bar 11 and the second cross bar 12 outside the protective tube 2 . A second dislocation groove 22 is opened on the outside of the protective tube 2 , and the limiting plate 17 is embedded in the second dislocation groove 22 .

[0043] As attached Figure 2 、 4As shown in Figures 7, 8 and 9, the second offset groove 22 is provided to offset the interference between the limiting plate 17 and the protective tube 2, so that the bottom end of the limiting plate 17 is embedded in the protective tube 2.

[0044] A deflection member 9 is hinged at one end of the shunt 8, and a handle 10 is hinged at the end of the deflection member 9 away from the shunt 8. A protective ring 20 is provided at the top of the protective tube 2, and a plurality of first offset grooves 21 are provided on the protective ring 20. A plurality of current converters 25 are distributed at the bottom of the protective ring 20, and each current converter 25 is respectively connected to the corresponding shunt 8 through a wire.

[0045] As attached Figure 2 、 4 As shown in Figures 5 and 6, by bending the handle 10, the function of adjusting the angle of the deflection member 9 is realized. When the deflection member 9 is deflected, the shunt 8 can be driven to deflect outside the central tube 6, so that the shunt 8 can be in contact with the top of the elastic conductive pin 7, making it convenient for the elastic conductive pin 7 to transmit the current through the shunt 8 to the current converter 25.

[0046] A base plate 18 is installed at the bottom of the protective tube 2 by bolts, and an electrode 19 is provided on the base plate 18. The top of the electrode 19 passes through the second electromagnet 4, the first electromagnet 3 and the central tube 6 in sequence and extends to the top of the box body 1, and the electrode 19 transmits the current to the shunt 8 through the reinforced conductive ring 5.

[0047] As attached Figure 1 、 2 As shown in Figures 3 and 5, the electrode 19 transfers the current to the shunt 8 through the reinforced conductive ring 5, which makes it easy to shunt and transport the current. When the current is connected through the electrode 19, it is also convenient for the second electromagnet 4 and the first electromagnet 3 to be energized to generate a repulsive force to drive the first electromagnet 3 and the second electromagnet 4 to move.

[0048] A cabinet door is hinged on one side of the surface of the box body 1 , and a guardrail 24 is embedded in the top of the box body 1 .

[0049] As attached Figure 1 As shown, the cabinet door is provided to facilitate opening the cabinet to disassemble and maintain the control components in the box body 1, while the guardrail 24 can protect the top of the electrode 19.

[0050] The vertical cross-sections of the first triangular groove 15 and the second triangular groove 16 are both triangular in shape. Conductive rings are respectively provided in the first electromagnet 3 and the second electromagnet 4. The conductive rings are slidably connected to the electrodes 19. The top of the electrodes 19 is provided with electrical terminals extending to the outside of the box 1.

[0051] As attached Figure 7 、 8As shown in FIG9 , the triangular cross-sectional shape of the first triangular groove 15 and the second triangular groove 16 allows the first cross bar 11 and the second cross bar 12 to move horizontally on the protective tube 2 through the triangular cross-sectional shape of the second triangular groove 16 and the first triangular groove 15 when the first electromagnet 3 and the second electromagnet 4 are displaced, and the provision of the conductive ring facilitates the transmission of the current on the electrode 19 to the first electromagnet 3 and the second electromagnet 4.

[0052] The plurality of handles 10 are respectively located in corresponding first offset grooves 21 and hinged to the protective ring 20 , and the central tube 6 is located in the middle of the protective ring 20 .

[0053] As attached Figure 2 and 4 As shown, the first offset groove 21 offsets the interference between the center tube 6 and the handle 10 and the protective ring 20, and also facilitates the positioning of the center tube 6.

[0054] The specific working principle is as follows: when current is input through the electrode 19, the current is conducted to the conductive ring inside the first electromagnet 3 and the second electromagnet 4 through the electrode 19. The force acting on the first electromagnet 3 and the second electromagnet 4 follows the law that like poles repel and opposite poles attract. If the two adjacent magnetic poles are the same, a repulsive force is generated; if the two adjacent magnetic poles are opposite, an attractive force is generated. The magnetic poles at the adjacent ends of the two are the same, and a repulsive force is generated to drive the first electromagnet 3 upward and the second electromagnet 4 downward axial displacement along the center tube 2. At this time, the first triangular groove 15 on the outside of the first electromagnet 3 pushes the first crossbar 11 to slide laterally on the center tube 2, and the second triangular groove 16 of the second electromagnet 4 synchronously drives the second crossbar 12 to move laterally. The triangular cross-section design of the triangular groove ensures the stability of the crossbar's lateral displacement, and the limit plate 17 on the crossbar is embedded in the second offset groove 22 of the center tube 2 to prevent excessive displacement of the crossbar.

[0055] When the first and second crossbars 11 and 12 move laterally, the inclined slots 13 at their bottom and top come into contact with the push rod 14. The inclined surface of the inclined slots 13 pushes the push rod 14 downward, compressing the spring 23. This allows the first and second crossbars 11 and 12 to form an elastic linkage through the push rod 14 and the spring 23. This allows the electromagnetic repulsive force to drive the first and second electromagnets 3 and 4 to move when power is supplied. When power is off, the elastic force of the spring 23 supports the first and second crossbars 11 and 12, preventing them from free-falling. This ensures precise control of the displacement stroke and a stable structure.

[0056] By twisting the handle 10, the deflector 9 drives the shunt 8 to deflect outside the central tube 6. When the shunt 8 contacts the elastic conductive pin 7, the current from the electrode 19 is transmitted to the shunt 8 through the reinforced conductive ring 5 and then connected to the current converter 25 at the bottom of the guard ring 20 via a wire. The current converter 20 converts the current parameters according to the needs, enabling independent current regulation and output of multiple modules. The elastic conductive pin 7 compresses and rebounds, contacting the shunt 8, ensuring close contact between the shunt 8 and the pin, preventing conduction losses.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
