Abstract
The utility model discloses a kind of relay symmetrical expression manganese copper diverter, and comprising: the first brace, it is positioned at the left side of the first plane; Second brace, it is positioned at the right side of described first plane, shunt body portion, and it is between described first brace and described second brace, and is fixedly connected with described first brace and the second brace respectively; Wherein, described shunt body portion has the rectangular opening laterally running through this shunt body portion, and this rectangular opening is by upper and lower for the segmentation of this shunt body portion two symmetrically and mutually disjunct first distributary division and the second distributary divisions.After second sample line of the present utility model is drawn from bottom, the sampling winding displacement groove formed from copper-manganese splitter body central position is drawn, is more mutually wound around extraction with the sample line of drawing from top, effectively can reduce the impact of extraneous power frequency magnetic field on copper-manganese splitter; Effectively can improve the power frequency magnetic field noise immunity of copper-manganese splitter.
Description
Technical field
The utility model relates to a kind of relay symmetrical expression manganese copper diverter.
Background technology
At present, for the matching used relay of watt-hour meter, in its face terminals, manganese copper diverter can be connected in series by welding manner, use manganese copper diverter as current measurement, extract signal for watt-hour meter and use.Therefore, the Electro Magnetic Compatibility of manganese copper diverter self is the importance affecting ammeter measuring precision, external electrical field, magnetic field all can cause certain influence to manganese copper diverter, wherein, the interference of power frequency magnetic field is exactly the very typical interference mode of one, and the power frequency magnetic field noise immunity improving manganese copper diverter ensures ammeter measuring effective means accurately.
Utility model content
The utility model object is that the defect existed for prior art provides a kind of relay symmetrical expression manganese copper diverter.
The utility model for achieving the above object, adopts following technical scheme: a kind of relay symmetrical expression manganese copper diverter, comprising:
First brace, it is positioned at the left side of the first plane;
Second brace, it is positioned at the right side of described first plane,
Shunt body portion, it is between described first brace and described second brace, and is fixedly connected with described first brace and the second brace respectively;
Wherein, described shunt body portion has the rectangular opening laterally running through this shunt body portion, and this rectangular opening is by upper and lower for the segmentation of this shunt body portion two symmetrically and mutually disjunct first distributary division and the second distributary divisions; The center, the back side of described first distributary division is prolonged longitudinal direction and is formed with the first concave part, and the front center position of described second distributary division is longitudinally formed with the second concave part; Described first concave part and described second concave part are established in the same way, to form sampling winding displacement groove;
The left upper end of described first distributary division is provided with the first sampling spot, and the bottom righthand side of described second distributary division is provided with the second sampling spot, described first sampling spot and the second sampling spot with described sampling winding displacement groove for symcenter;
Second sample line of drawing from described second sampling spot is successively by being mutually wound around extraction with first sample line of drawing from described first sampling spot after described second concave part, rectangular opening and the first concave part.
The beneficial effects of the utility model: after the second sample line of the present utility model is drawn from bottom, the sampling winding displacement groove formed from copper-manganese splitter body central position is drawn, mutually be wound around extraction with the sample line of drawing from top again, effectively can reduce the impact of extraneous power frequency magnetic field on copper-manganese splitter; Effectively can improve the power frequency magnetic field noise immunity of copper-manganese splitter, make the metering of matching used relay watt-hour meter more accurate.
