For achieving the above object, the utility model provides a kind of manganese copper diverter, and comprise copper-manganese resistive element and two conducting strip folders, described copper-manganese resistive element is a tabular, and has preset resistive value;
Described two conducting strips folder is clamped in the two ends of described copper-manganese resistive element respectively, each conducting strip folder includes upper and lower two conducting strips, the end section of described upper and lower two conducting strips combines, and fore-end opens certain angle, the two ends of described copper-manganese resistive element are inserted in the fore-end opened;
Each conducting strip folder is welded with binding post, and sample line is connected to binding post, and two sample line on two conducting strips folders are wrapped around one another is twisted one stranded wire;
Wherein, described two conducting strips folder is connected to the two ends of voltage table by sample line, to form the in parallel of copper-manganese resistive element and voltage table, distributes sub-fraction electric current and makes voltage table indicators turn with the big current in metering circuit.
Copper-manganese resistive element is clamped between conducting strip folder, facilitates dismounting and the replacing of shunt; Two sample line are wrapped around one another is twisted one stranded wire, reduces the loop area in magnetic field, thus greatly reduces the impact on shunt of alternating magnetic field.
Preferably, the fore-end of described upper and lower two conducting strips all has recess, and the depression direction of two recesses is direction close to each other, and the every one end in the two ends of described copper-manganese resistive element is by described two recesses clamping.
Preferably, the flared section undulate of described two conducting strips folder.
The flared section undulate of two conducting strip folders, improves the firmness that conducting strip folder clamps with copper-manganese resistive element, prevents copper-manganese resistive element from coming off from conducting strip folder is last;
Preferably, the ratio of described each conducting strip folder tail end bound fraction and front end flared section is 3: 1.
The ratio of tail end and front end flared section is moderate, can improve the fatigue strength of conducting strip folder, increase the service life.
Preferably, the tail end closure office of described two conducting strips folder is equipped with through hole, and described each through hole bolt presses is fixed, and the area of each through hole is less than 1/10th of each conducting strip folder area.
Improve the snap-in force between conducting strip folder, conducting strip is pressed from both sides and clamps more firm with copper-manganese resistive element.
Preferably, the thickness of described binding post press from both sides with conducting strip in the thickness of one of them conducting strip identical.
Preferably, described sample line is weldingly fixed on binding post.
The beneficial effect of utility model:
The utility model is clamped between conducting strip folder by copper-manganese resistive element, facilitates dismounting and the replacing of shunt; The flared section undulate of two conducting strip folders, improves the firmness that conducting strip folder clamps with copper-manganese resistive element, prevents copper-manganese resistive element from coming off from conducting strip folder is last; Two sample line are wrapped around one another is twisted one stranded wire, reduces the loop area in magnetic field, thus greatly reduces the impact on shunt of alternating magnetic field.
