Background technology
As shown in Figure 1, the manganese copper diverter that the electric energy meter of prior art adopts generally comprises two binding posts 1 ' and a copper-manganese sheet 2 ', described two binding posts 1 ' are fixedly connected with the two ends of copper-manganese sheet 2 ' respectively, two binding posts 1 ' are respectively equipped with a connection terminal 3 ' near an end of copper-manganese sheet 2 ' or the two ends of copper-manganese sheet 2 ', two connection terminals 3 ' all are connected with an extension line 4 ', article two, the connecting portion 401 ' of extension line 4 ' lower end is connected with a connection terminal 3 respectively, article two, the extension 402 ' of extension line 4 ' is connected with connecting portion 401 ' and extends upward, connecting portion 401 ' even copper-manganese sheet 2 ' the vertical setting of described two extension lines 4 ', this manganese copper diverter has the following disadvantages: by the law of electromagnetic induction as can be known, when the magnetic flux that passes a closed-loop path changes, this closed-loop path will produce induction current, the closed-loop path area is larger, magnetic flux change is more obvious, just more easily produce induction current, the connecting portion 401 ' of two extension lines 4 ' of this manganese copper diverter all with 2 ' the vertical setting of copper-manganese sheet, during the access ammeter, make the loop area of current sampling circuit of extension line 4 ' larger, so that when doing the tests such as power frequency magnetic field, easily induce electric current, diamagnetic interference is relatively poor, makes measuring error larger.
The utility model content
Technical problem to be solved in the utility model is to provide the loop area that makes current sampling circuit to reduce, strengthen diamagnetic interfering manganese copper diverter.
For solving the problems of the technologies described above, the manganese copper diverter that the utility model provides, it comprises two binding posts and a copper-manganese sheet, described two binding posts are fixedly connected with the two ends of copper-manganese sheet respectively, two binding posts are respectively equipped with a connection terminal near an end of copper-manganese sheet or the two ends of copper-manganese sheet, two connection terminals all are connected with an extension line, article two, the connecting portion of extension line lower end is connected with a connection terminal respectively, article two, the extension of extension line is connected with connecting portion and extends upward, the connecting portion of described two extension lines all be arranged in parallel with the copper-manganese sheet and extends along relative direction, the connecting portion that is to say the left side extends to the right from pad, the connecting portion on right side extends to the left from pad, has reduced the loop area of current return between two extension lines.
After adopting above structure, the utility model compared with prior art has advantages of following:
Article two, the connecting portion of extension line all be arranged in parallel with the copper-manganese sheet and extends along relative direction, when making the access ammeter, the loop area of the current sampling circuit of extension line reduces, and does not allow to be subject to the interference of external magnetic field, diamagnetic interference strengthens, and makes to measure to be not easy to occur error.
As improvement, the extension of described two extension lines closely twines mutually, further reduces the loop area of the current sampling circuit of extension line.
As further improvement.Described two binding posts are fixedly connected with the two ends of copper-manganese sheet respectively and refer to that two binding posts fix by electron beam welding with the two ends of copper-manganese sheet respectively, the connecting portion of described two extension line lower ends is connected with a connection terminal respectively and refers to that two connecting portions fix by electron beam welding with a connection terminal respectively, electron beam welding is as the processing thermal source with high-power electron beam, metal with the beam bombardment weldment joint of high-energy-density, make its Flashmelt, then cool off rapidly the purpose that reaches welding, the weld seam of electron beam welding is extremely narrow and welding effect good.
