Abstract
The utility model relates to a U-shaped manganin shunting sheet for a relay. The U-shaped manganin shunting sheet for the 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; the manganin shunting sheet body is U-shaped; and the first sampling point and the second sampling point are respectively located on the U-shaped two ends of the manganin shunting sheet body. The U-shaped manganin shunting sheet for the relay has the beneficial effects that as the manganin shunting sheet body is U-shaped, an effective area of the manganin shunting sheet vertically penetrated by an external power frequency magnetic field can be reduced, the influence of the external power frequency magnetic field on the manganin shunting sheet is then reduced, immunity of the manganin shunting sheet against the power frequency magnetic field can be effectively improved, 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 relay copper-manganese splitter, relates in particular to this relay copper-manganese splitter shape.
Background technology
For the matching used relay of kilowatt-hour meter, can use the copper-manganese splitter as current measurement by welding manner serial connection copper-manganese splitter on its face terminals, extract signal for kilowatt-hour meter and use.Therefore, the Electro Magnetic Compatibility of copper-manganese splitter self is the importance that affects the ammeter measuring precision, certain influence all can be caused to the copper-manganese splitter 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 the copper-manganese splitter 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 U-shaped copper-manganese splitter, 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 point and the second sampling point are set; Described copper-manganese splitter body takes the shape of the letter U; Described the first sampling point and the second sampling point lay respectively at the U-shaped two ends of copper-manganese splitter body.
Compared with prior art, the beneficial effects of the utility model are: because copper-manganese splitter body takes the shape of the letter U, can reduce the effective area that extraneous power frequency magnetic field vertically passes the copper-manganese splitter, thereby 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 kilowatt-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 U-shaped copper-manganese splitter, comprise that series winding is welded in copper-manganese splitter body 1 and two sampling points (2,3) on the relay face terminals 4, described copper-manganese splitter body 1 takes the shape of the letter U, and two sampling points (2,3) lay respectively at the U-shaped two ends of copper-manganese splitter body 1.
Because copper-manganese splitter body takes the shape of the letter U, and can reduce the effective area that extraneous power frequency magnetic field vertically passes the copper-manganese splitter, thereby reduce extraneous power frequency magnetic field to the impact of copper-manganese splitter.
