Abstract
The present invention provides an interdigital instrument terminal bus bar, which comprises a stator fixed with the bus bar, a strip finger fixed on one side of the stator and fixing holes on the stator. Wherein, fixing holes are arranged at one end of the finger. The finger is higher than a right angle of a corner while the stator is fixed. With a simple and rational structure, the present invention can not only effectively improve measuring precision of electric energy meters of different COS Phi but also eliminate impact amongst users of electric energy meters.
Description
(1) technical field
The present invention relates to electric energy metrical and calibration technology, be specifically related to a kind of energy meter terminal.
(2) background technology
At present, be applied in the terminal combination on the electric energy meter product, comprise that terminal, bus-bar and shunt etc. nearly all adopt the square loop configuration.The monomer electric energy meter of square annular end sub-portfolio structure at COS Φ not simultaneously, precision differs greatly.The multiuser electric energy meter of square annular end sub-portfolio structure also will be subjected to influencing between the family.Therefore, the structure of table terminal has considerable influence to the aspects such as precision of electric power meter and calibration equipment, and does not also have a kind of defective that terminal structure can overcome the square loop configuration of showing in the market.
(3) summary of the invention
The object of the present invention is to provide a kind of simple and reasonable, can effectively improve electric energy meter in the asynchronous measuring accuracy of COS Φ, can overcome the finger-fork type instrument terminals bus-bar wire that influences between the family that multiuser electric energy meter is subjected to again.
The object of the present invention is achieved like this: it comprises with the fixing stator of busbar and is arranged on the interdigital of stator one side, and stator is provided with fixed orifice, and interdigital elongated, outer ends is provided with fixed orifice.
The present invention also has some technical characterictics like this:
1, the described interdigital stator setting that is higher than, interdigital connection knuckle place is the right angle;
2, the fixed orifice on the described stator is arranged in the middle of the stator, the interdigital fixed orifice both sides of listing in respectively;
3, the fixed orifice on the described stator is arranged on stator one end, interdigitally comprises at least one group, is arranged on the stator other end;
4, the fixed orifice on the described stator is arranged on stator one end, the interdigital stator other end that is set in qually spaced in;
5, described stator in the middle of the place be provided with upwards projection, projection is provided with fixed orifice, interdigitally lists in protruding both sides respectively.
Finger-fork type instrument terminals bus-bar wire of the present invention is mainly used on the multiuser electric energy meter.Also can be applicable to have good expansion in various electric power meters such as three-phase electric energy meter and single-phase electric energy meter and the calibration equipment.The position of fixed orifice can be different according to different terminals on the stator, and the terminal that promptly cooperates the multi-user to show can have different distortion, and interdigital quantity can increase and decrease with different house types with different terminals.
Beneficial effect of the present invention has:
(1) thoroughly solved in the past multiuser electric energy meter when different COS Φ value, precision changes great problem;
(2) solved thoroughly in the past that precision influences great problem between the multiuser electric energy meter family;
(3) when guaranteeing multiuser electric energy meter high density (distance between metering units and the metering units), can guarantee that its precision on each current point of COS Φ is almost constant, COS Φ=1.0 for example, COS Φ=0.5, COS Φ=0.8;
(4) when guaranteeing multiuser electric energy meter high density (distance between metering units and the metering units), can guarantee precision between metering units and the metering units do not influence each other (just influencing between the family of saying usually);
(5) multiuser electric energy meter of application structure of the present invention can improve an accuracy class than the multiuser electric energy meter that otherwise connects;
(6) application electric energy meter of the present invention can save the lead-in wire between shunt and the metering units;
(7) use electric energy meter of the present invention neat and artistic, solid and reliable, be easy to assembling.
