Abstract
The utility model relates to a round hole wire-passing type manganin shunting device for a relay. The round hole wire-passing type manganin shunting device for a relay comprises a manganin shunting sheet body which is in series connection with relay load terminals and welded on the relay load terminals; a first sampling point and a second sampling point are arranged on the manganin shunting sheet body; a first sampling wire and a second sampling wire which are mutually wound are respectively connected and introduced out from the first sampling point and the second sampling point; a round hole is arranged in the middle of the manganin shunting sheet body; the first sampling point and the second sampling point are symmetrical with the round hole as the center, and are respectively arranged on the upper part and the lower part at the combination places of the manganin shunting sheet body and the load terminals; and the second sampling wire introduced form the second sampling point passes through the round hole from the front side of the manganin shunting sheet body till the back side of the manganin shunting sheet body, and are wound with the first sampling wire introduced from the first sampling point and introduced out. The round hole wire-passing type manganin shunting device for a relay has the beneficial effects that the influence of the external power-frequency magnetic field on the manganin shunting sheet is then reduced and measurement of the relay watt hour meter matched for use is more accurate.
Description
Technical field
The utility model relates to a kind of manganese copper diverter, relates in particular to the structure of this manganese copper diverter.
Background technology
For the matching used relay of watt-hour meter, can use manganese copper diverter as current measurement by welding manner serial connection manganese copper diverter on its face terminals, extract signal for watt-hour meter and use.Therefore, the Electro Magnetic Compatibility of manganese copper diverter self is the importance that affects the ammeter measuring precision, certain influence all can be caused to manganese copper diverter in external electrical field, magnetic field, wherein, the interference of power frequency magnetic field is exactly a kind of very typical interference mode, and the power frequency magnetic field immunity to interference that improves manganese copper diverter is to guarantee accurately effective means of ammeter measuring.
Summary of the invention
The utility model technical issues that need to address have provided a kind of relay with circular hole threading type manganese copper diverter, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: series winding is welded in the copper-manganese splitter body on the relay face terminals; At described copper-manganese splitter body the first sampling spot and the second sampling spot are set; From the first sampling spot be connected sampling spot and connect respectively the first sample line and second sample line of drawing mutual winding; The middle part of described copper-manganese splitter body is provided with circular hole; The first sampling spot and the second sampling spot are located at respectively the upper and lower of copper-manganese splitter body and face terminals combination take circular hole as symcenter; Connect the second sample line draw from the second sampling spot and pass circular hole to the back side of copper-manganese splitter body from the front of copper-manganese splitter body, and be connected first sample line of drawing from the first sampling spot and mutually twine and draw.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting said structure, after one sample line is drawn from the bottom, the back side of boring a hole from the front of copper-manganese splitter body, mutually twine with the sample line of drawing from top again and draw, can effectively reduce extraneous power frequency magnetic field to the impact of copper-manganese splitter; Power frequency magnetic field immunity to interference that can Effective Raise copper-manganese splitter is so that the metering of matching used relay watt-hour meter is more accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: relay of the present utility model circular hole threading type manganese copper diverter, comprise that series winding is welded in copper-manganese splitter body 1 and two sampling spots (2,3) on the relay face terminals 7, connects two sample lines (4,5) of drawing mutual winding from two sampling spots (2,3) respectively; The middle part of described copper-manganese splitter body 1 is provided with circular hole 6; Two sampling spots (2,3) are located at respectively the upper and lower of copper-manganese splitter body 1 and face terminals 7 combinations take circular hole 6 as symcenter; Connect second sample line 5 of drawing from the second sampling spot 3 and pass circular hole 6 to the back side of copper-manganese splitter body 1 from the front of copper-manganese splitter body 1, with is connected from the first sampling spot 2 first sample line 4 of drawing mutually windings draw.
