[0065] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0066] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application 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 limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0067] like Figures 1 to 3As shown, the electronic electric energy meter of the embodiment of the present application includes a relay 10. The relay 10 has a shunt plate assembly 20 and two lead-out terminals 11, one of which is used as a current inflow lead-out terminal, and the other lead-out terminal 11 is used as a current outflow lead-out terminal. The shunt plate assembly 20 is arranged on one of the lead-out terminals 11. The shunt plate assembly 20 is connected to a sampling circuit board (not shown in the figure) through conductors (31, 32).

[0068] Among them, for the relay 10, the structure in the prior art can be adopted, which will not be described in detail here.

[0069] Please continue reading Figures 1 to 3 The shunt sheet assembly 20 of the embodiment of the present application includes a first shunt sheet 100 and a second shunt sheet 200. The first shunt sheet 100 includes two first conductive segments 110 and a first sampling segment 120 connected to the two first conductive segments 110; the second shunt sheet 200 includes two second conductive segments 210 and a second sampling segment 220 connected to the two second conductive segments 210. The two second conductive segments 210 are electrically connected to the two first conductive segments 110, respectively, so that the first sampling segment 120 and the second sampling segment 220 are arranged in parallel. The corresponding connection positions of the first conductive segments 110 and the second conductive segments 210 form an electrical connection area 300.

[0070] The first sampling section 120 of the first shunt sheet 100 and the second sampling section 220 of the second shunt sheet 200 are made of high resistivity material, such as manganese copper. Of course, the first sampling section 120 and the second sampling section 220 can also be made of constantan or nickel-chromium or iron-chromium-aluminum.

[0071] The first conductive segment 110 of the first shunt sheet 100 and the second conductive segment 210 of the second shunt sheet 200 are made of conductive material, such as copper. Of course, the first conductive segment 110 and the second conductive segment 210 can also be made of bronze, iron-copper alloy, brass or other conductive materials.

[0072] In the embodiment of the present application, the first sampling section 120 and the second sampling section 220 of the shunt plate assembly 20 are arranged in parallel, thereby improving the overload capacity and heat dissipation capacity of the entire loop and preventing high temperature from affecting the resistance value of the sampling resistor.

[0073] For the sake of convenience, the length direction of the first diverter 100 is defined as the first direction D1, the width direction of the first diverter 100 is defined as the second direction D2, and the thickness direction of the first diverter 100 is defined as the third direction D3. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

[0074] Please continue reading Figures 1 to 3The first shunt sheet 100 further includes two first sampling portions 130, and the first sampling portion 130 is used to connect to a first conductor 31. The two first sampling portions 130 are located between the two electrical connection areas 300. The second shunt sheet 200 further includes two second sampling portions 230, and the second sampling portions 230 are used to connect to a second conductor 32. The two second sampling portions 230 are located between the two electrical connection areas 300.

[0075] The first conductor 31 and the second conductor 32 may be soft cables or hard metal parts, which is not limited in the present application.

[0076] In one embodiment, the two first adopting portions 130 may be respectively disposed on the two first conductive segments 110 ; in another embodiment, the two first adopting portions 130 are both disposed on the first sampling segment 120 .

[0077] Likewise, in one embodiment, the two second sampling portions 230 may be respectively disposed in the two second conductive segments 210 ; in another embodiment, the two second sampling portions 230 are both disposed in the second sampling segment 220 .

[0078] In addition, the first sampling portion 130 and the second sampling portion 230 may be a protrusion or a plane. When the first sampling portion 130 is a plane, part of the outer surface of the first conductive segment 110 or part of the outer surface of the first sampling segment 120 may be considered as the first sampling portion 130; when the second sampling portion 230 is a plane, part of the outer surface of the second conductive segment 210 or part of the outer surface of the second sampling segment 220 may be considered as the second sampling portion 230.

[0079] Next, the first sampling portion 130 and the second sampling portion 230 are taken as an example to be described as protrusions.

[0080] like Figures 1 to 3 As shown, in the embodiment of the present application, each first conductive segment 110 is provided with a first sampling portion 130 , and each second conductive segment 210 is provided with a second sampling portion 230 .

[0081] In the embodiment of the present application, the first shunt sheet 100 is provided with two first sampling parts 130 corresponding to the first sampling section 120, and the second shunt sheet 200 is provided with two second sampling parts 230 corresponding to the second sampling section 220. When the first sampling part 130 is connected to the first conductor 31, and the second sampling part 230 is connected to the second conductor 32, for the first shunt sheet 100, the current flowing into one of the first sampling parts 130 flows through the first sampling section 120 and then flows out from the other first sampling part 130; for the second shunt sheet 200, the current flowing into one of the second sampling parts 230 flows through the second sampling section 220 and then flows out from the other second sampling part 230.

[0082] It can be seen that in the shunt sheet assembly 20 of the embodiment of the present application, the two first sampling parts 130 and the two second sampling parts 230 are located between the two electrical connection areas 300, so that the sampling current does not flow through the electrical connection area 300 between the first shunt sheet 100 and the second shunt sheet 200, thereby avoiding fluctuations in the sampling resistance, improving the stability of the sampling resistance, and thus ensuring measurement accuracy.

[0083] like Figure 4 As shown, each first conductive segment 110 includes a first connecting segment 111 and a first extending segment 112, a first sampling segment 120 is connected between two first extending segments 112, the first extending segment 112 is connected between the first connecting segment 111 and the first sampling segment 120, and two second conductive segments 210 are respectively electrically connected to the two first connecting segments 111; the corresponding connecting positions of the second conductive segments 210 and the first connecting segments 111 form an electrical connection area 300. Each first extending segment 112 is provided with a first sampling portion 130.

[0084] In the length direction (first direction D1) of the first flow divider 100, one first connecting section 111, one first extending section 112, the first sampling section 120, another first extending section 112 and another first connecting section 111 are arranged in sequence. The first flow divider 100 is generally in the shape of a letter "I".

[0085] In the embodiment of the present application, the first sampling portion 130 is protruding from the first extension section 112, and the first extension section 112 is connected to one end of the first connecting section 111 close to the first sampling section 120. The first extension section 112 is not directly connected to the second conductive section 210 of the second shunt sheet 200, so that the sampling current in the first shunt sheet 100 only flows through the two first sampling portions 130, the two first extension sections 112 and the first sampling section 120, but does not flow through the two first connecting sections 111, thereby avoiding fluctuations in the sampling resistance.

[0086] Please continue reading Figure 4 Along the width direction (second direction D2) of the first diverter plate 100, the two first sampling portions 130 protrude from the first side surfaces 1121 of the two first extension sections 112 respectively.

[0087] Each first extension section 112 has two first side surfaces 1121 disposed opposite to each other along the width direction (second direction D2) of the first flow divider 100. The two first sampling portions 130 included in the first flow divider 100 protrude from the first side surfaces 1121 of the two first extension sections 112 in a manner that: the two first sampling portions 130 protrude from the first side surface 1121 on the same side of the two first extension sections 112. Of course, it can also be: the two first sampling portions 130 protrude from the first side surface 1121 on the opposite side of the two first extension sections 112. In other words, the protruding directions of the two first sampling portions 130 can be the same or opposite.

[0088] In the embodiment of the present application, the two first sampling portions 130 included in the first flow dividing piece 100 protrude in the same direction and protrude from the first side surfaces 1121 on the same side of the two first extending sections 112 .

[0089] In one embodiment, the protruding direction of each first sampling portion 130 is parallel to the width direction (second direction D2) of the first flow dividing plate 100, but the present invention is not limited thereto. For example, the protruding direction of each first sampling portion 130 may also have an angle with the width direction (second direction D2) of the first flow dividing plate 100.

[0090] like Figure 5 and Figure 6 As shown, each second conductive segment 210 includes a second connecting segment 211 and a second extension segment 212, the second sampling segment 220 is connected between the two second extension segments 212, the two second connecting segments 211 are respectively connected to one end of the two second extension segments 212 away from the second sampling segment 220; the two second connecting segments 211 are respectively electrically connected to the two first connecting segments 111; the corresponding connecting positions of the second connecting segments 211 and the first connecting segments 111 form an electrical connection area 300. Each second extension segment 212 is provided with a second sampling portion 230.

[0091] In one embodiment, the second connection segment 211 and the corresponding first connection segment 111 may be connected by welding, but the present invention is not limited thereto.

[0092] In the embodiment of the present application, the second sampling portion 230 is protruding from the second extension section 212, and the second extension section 212 is not directly connected to the first conductive section 110 of the first shunt sheet 100, so that the sampling current in the second shunt sheet 200 only flows through the two second sampling portions 230, the two second extension sections 212 and the second sampling section 220, but does not flow through the two second connecting sections 211, thereby avoiding fluctuations in the sampling resistance.

[0093] In one embodiment, the second extension segment 212 includes a first segment 2121 and a second segment 2122. The second sampling segment 220 is connected between two first segments 2121, and each first segment 2121 is provided with a second sampling portion 230. The second segment 2122 is vertically connected to the first segment 2121 and is vertically connected to the corresponding second connection segment 211. The second flow splitter 200 is generally in a "ji" shape.

[0094] Please continue to refer to Figure 5 and Figure 6 , along the width direction of the second flow splitter 200, the two second sampling portions 230 respectively protrude from the second side surfaces 2123 of the two second extension segments 212. It should be noted that the width direction of the second flow splitter 200 is parallel to the width direction of the first flow splitter 100, that is, both are the second direction D2.

[0095] Wherein, each second extension segment 212 has two second side surfaces 2123 arranged opposite to each other along the width direction (second direction D2) of the second flow splitter 200. The two second sampling portions 230 included in the second flow splitter 200 can protrude from the second side surfaces 2123 of the two second extension segments 212 in the following ways: the two second sampling portions 230 protrude from the second side surfaces 2123 on the same side of the two second extension segments 212. Of course, it can also be: the two second sampling portions 230 protrude from the second side surfaces 2123 on the opposite sides of the two second extension segments 212. In other words, the protruding directions of the two second sampling portions 230 can be the same or opposite.

[0096] In the embodiment of the present application, the protruding directions of the two second sampling portions 230 included in the second flow splitter 200 are the same, and respectively protrude from the second side surfaces 2123 on the same side of the two second extension segments 212.

[0097] In one embodiment, the protruding direction of each second sampling portion 230 is parallel to the width direction of the second flow splitter 200, but not limited thereto. For example, the protruding direction of each second sampling portion 230 can also have an included angle with the width direction of the second flow splitter 200.

[0098] Such as Figure 2 , Figure 7 and Figure 8As shown, the protruding directions of the first sampling portions 130 of the two first conductive segments 110 are the same, the protruding directions of the second sampling portions 230 of the two second conductive segments 210 are the same, and the protruding directions of the first sampling portions 130 and the second sampling portions 230 are opposite. In other words, the two first sampling portions 130 are arranged on the same side of the width direction (second direction D2) of the first shunt sheet 100, the two second sampling portions 230 are arranged on the same side of the width direction (second direction D2) of the second shunt sheet 200, and the first sampling portions 130 and the second sampling portions 230 are located on different sides of the width direction of the first shunt sheet 100 and the second shunt sheet 200.

[0099] In the embodiment of the present application, the first shunt sheet 100, the two first conductors 31 connected to the two first sampling parts 130, and the sampling circuit board form a first loop, and the second shunt sheet 200, the two second conductors 32 connected to the two second sampling parts 230, and the sampling circuit board form a second loop. When the electronic electric energy meter is exposed to the power frequency magnetic field, the first loop generates a first induced current, and the second loop generates a second induced current. Since the protruding directions of the first sampling part 130 and the second sampling part 230 are opposite, the flow directions of the first induced current and the second induced current are opposite, so the first induced current and the second induced current weaken each other, thereby reducing the degree to which the electronic electric energy meter is affected by the power frequency magnetic field.

[0100] Specifically, when the interfering magnetic field passes through the first loop and the second loop along the thickness direction (third direction D3) of the first shunt sheet 100, according to Ampere's law, the flow direction of the first induced current is Figure 7 As shown by the arrow in the middle, the direction of the second induced current is Figure 8 Indicated by the arrow.

[0101] It can be seen that the first induced current and the second induced current flow in opposite directions, and thus can weaken each other, thereby reducing the impact of the power frequency magnetic field on the electronic electric energy meter.

[0102] It should be noted that Figure 7 and Figure 8 The direction of the induced current shown is based on the interference magnetic field passing through the first loop and the second loop from the outside of the paper to the inside of the paper. If the interference magnetic field passes through the first loop and the second loop from the inside of the paper to the outside of the paper, then the direction of the first induced current is the same as Figure 7 In contrast to the direction of the second induced current, Figure 8 The opposite is shown.

[0103] like Figure 4 and Figure 6, the orthographic projection area of ​​the first sampling segment 120 on a virtual plane is S1, the orthographic projection area of ​​the second sampling segment 220 on the virtual plane is S2, S1=S2; wherein the virtual plane is parallel to the first sampling segment 120 (ie, the virtual plane is perpendicular to the third direction D3).

[0104] According to the law of electromagnetic induction, the area perpendicular to the direction of the magnetic field is related to the magnitude of the induced electromotive force. Therefore, by designing area S1 and area S2 to be equal, the induced electromotive force generated by the interfering magnetic field in the first circuit and the induced electromotive force generated by the interfering magnetic field in the second circuit can be completely offset, thereby eliminating the influence of the magnetic field on the electric energy meter.

[0105] It should be noted that, due to the influence of factors such as processing technology and assembly accuracy, it is difficult to make area S1 and area S2 completely equal, so S1=S2 in the embodiment of the present application should be understood as being approximately equal. It can be understood that the difference between S1 and S2 determines the size of the remaining induced electromotive force after the induced electromotive force generated by the first circuit and the induced electromotive force generated by the second circuit are offset, so when the size of the remaining induced electromotive force is not enough to affect the electric energy meter, although S1 and S2 are not completely equal, this situation should also be included in the protection scope of the present application.

[0106] It should be noted that when the two first adopting parts 130 are both arranged in the first sampling section 120, and the two second sampling parts 230 are both arranged in the second sampling section 220, in order to achieve the effect of "the induced electromotive force generated by the interfering magnetic field in the first loop and the induced electromotive force generated by the interfering magnetic field in the second loop can be completely offset", it is necessary to meet the following conditions:

[0107] The orthographic projection area of ​​the two first adopting parts 130 and the first sampling section 120 located between the two first adopting parts 130 on the virtual plane is S3, and the orthographic projection area of ​​the two second sampling parts 230 and the second sampling section 220 located between the two second sampling parts 230 on the virtual plane is S4, S3 = S4. The virtual plane is parallel to the second sampling section 220 (that is, the virtual plane is perpendicular to the third direction D3).

[0108] In summary, the advantages and beneficial effects of the shunt plate assembly 20, the relay and the electronic energy meter of the embodiment of the present application include at least:

[0109] The first sampling section 120 and the second sampling section 220 of the shunt sheet assembly 20 of the embodiment of the present application are arranged in parallel, and the first sampling part 130 is arranged at both ends of the first sampling section 120, and the second sampling part 230 is arranged at both ends of the second sampling section 220. On the one hand, the overload capacity and heat dissipation capacity of the entire circuit are improved; on the other hand, the sampling current does not flow through the connection between the first shunt sheet 100 and the second shunt sheet 200, thereby avoiding the fluctuation of the sampling resistor, improving the stability of the sampling resistor, and thus ensuring the measurement accuracy.

[0110] In addition, since the first sampling portion 130 and the second sampling portion 230 protrude in opposite directions, the first induced current and the second induced current flow in opposite directions, so the first induced current and the second induced current weaken each other, thereby reducing the degree to which the electronic electric energy meter is affected by the industrial frequency magnetic field.

[0111] Furthermore, by designing the area S1 and the area S2 to be equal, the induced electromotive force generated by the interfering magnetic field in the first loop and the induced electromotive force generated by the interfering magnetic field in the second loop can be completely offset, thereby eliminating the influence of the magnetic field on the electric energy meter.
