Abstract
The utility model relates to an electric energy meter comprising a PCB (Printed Circuit Board) (2) and a manganin diverter (1), wherein the PCB (2) and the manganin diverter (1) are connected with each other by a connecting wire (3), and a plane where the manganin diverter (1) is arranged is vertical to a plane where the PCB is arranged. By adopting the electric energy meter with the structure, a ring formed by the connecting wire near the manganin diverter is vertical to a ring formed by the connecting wire near the PCB, so that when the electric energy meter is influenced by an outer magnetic field, only one of the two rings is affected, and the other ring is vertical to the outer magnetic field so as not to be interfered, thereby generating less reaction power-driven potential, so as to reduce errors.
Description
Technical field:
The utility model relates to electric energy meter and manufactures the field, specifically is a kind of electric energy meter that uses manganese copper diverter as the current channel sampled signal.
Background technology:
At present, use the electric energy meter of manganese copper diverter as the current channel sampled signal, the manganese copper diverter operated by rotary motion is in the electric energy meter housing, and with the same plane of pcb board, manganese copper diverter adopts connecting line to be connected with pcb board, connecting line can form a ring near pcb board, near manganese copper diverter, also can form a ring, these two rings are on the same plane, if when electric energy meter was subjected to the external magnetic field interference, these two rings might all be subjected to the interference of external magnetic field, produce induction electromotive force, pass to the computation chip on the pcb board, thereby cause error higher.
The utility model content:
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, provides a kind of error lower electric energy meter.
Technical solution of the present utility model is, a kind of electric energy meter is provided, and it comprises pcb board, manganese copper diverter, and described pcb board adopts connecting line to be connected with manganese copper diverter, and the plane at described manganese copper diverter place is vertical with the plane at pcb board place.
After adopting said structure, the utlity model has following advantage:
In the utility model electric energy meter, the plane at manganese copper diverter place is vertical with the plane at pcb board place, so ring that near the connecting line manganese copper diverter forms then with pcb board near the ring that forms of connecting line vertical mutually, when electric energy meter was subjected to the external magnetic field interference, these two rings had only a ring to be interfered like this, and another ring is vertical with external magnetic field, and can not be interfered, so, the induction electromotive force of generation can be little a lot, thereby can reduce error.
Description of drawings:
Accompanying drawing 1 is the schematic top plan view of the utility model electric energy meter;
Accompanying drawing 2 is schematic side view of the present utility model;
As shown in the figure: 1, manganese copper diverter, 2, pcb board, 3, connecting line;
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3: the utility model provides a kind of electric energy meter, it comprises pcb board 2, manganese copper diverter 1, described pcb board 2 adopts connecting line 3 to be connected with manganese copper diverter 1, the plane at described manganese copper diverter 1 place is vertical with the plane at pcb board 2 places, be among Fig. 2, two sides, manganese copper diverter 1 left and right sides, all the upper and lower surface with pcb board 2 is vertical, because connecting line 3 has many, so adopt the line cover with its bundle together, connecting line is near manganese copper diverter 1 and pcb board 2 as can be seen, can form a ring respectively, because the plane at manganese copper diverter 1 place is vertical with the plane at pcb board 2 places, so, these two rings are also vertical mutually, because connecting line 3 is metal material, therefore, when electric energy meter is in power frequency external magnetic field following time, these two rings have only a meeting to be subjected to the influence of the external magnetic field of alternation, another ring is vertical with external magnetic field, and can not be interfered, so, the induction electromotive force that produces can be little a lot, thereby can reduce error.
Certainly; above-mentioned explanation is not to be limit value to essential scope of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art person has done in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
