Abstract
Internal-sampling power frequency interference-resisting diverters relate to diverters for a metering device in an intelligent electric meter. The problem that the utility model needs to solve is to design the power frequency interference-resisting diverters used for the metering device in the intelligent electric meter to prevent influences on the precision of metering. The technical scheme of the utility model is that the diverters are formed by welding a static reed and a connecting piece; the rear end of the static reed is provided with a static reed contact riveting hole; one side of the static reed is provided with a groove-shaped jack used for embedded inside a shell of a relay; the rear end of the connecting piece is provided with a bending angle-shaped hole seat used for connecting with the electric meter; a manganin piece is welded between the static reed and the connecting piece; and the diverter is characterized in that three through holes and two gap bridges are formed in the central axis of the manganin piece, the three through holes are arranged consistent to the direction of current, the direction of the gap bridges is perpendicular to the direction of the current, the two gap bridges separate the three through holes from one another so as to form the two diverters, and the two gap bridges are used as sampling points of the diverters.
Description
Technical field
The utility model relates to the shunt of metrology devices in the intelligent electric meter.
Background technology
A kind of shunt that is made of static contact spring piece and brace welding is arranged in the prior art, and the static contact spring piece rear end is shaped on quiet spring contact riveting hole, one side static contact spring piece has one to be used for being embedded in the interior groove shape socket of relay housing; Sector hole seat that is used for connecting ammeter of brace rear end welding, welding copper-manganese sheet between static contact spring piece and brace is one side the shunt main body has a resistance sampling point.Shunt is the metrology devices in the intelligent electric meter, and accuracy requirement is than higher, and shunt is in the past disturbed by power frequency all easily, the vicious metering electric signal of meeting under power frequency is disturbed, the precision of influence metering.
Summary of the invention
The problem that the utility model need solve is a kind of shunt for the anti-power frequency interference of intelligent electric meter meter of design, avoids influencing the precision of metering.
The technical solution of the utility model is made of static contact spring piece and brace welding, and the static contact spring piece rear end is shaped on quiet spring contact riveting hole, one side static contact spring piece has one to be used for being embedded in the interior groove shape socket of relay housing; Sector hole seat that is used for connecting ammeter of brace rear end welding, welding copper-manganese sheet between static contact spring piece and brace, it is characterized in that being shaped on three through holes and two gap bridges at copper-manganese sheet central axis, the arrangement of three through holes is consistent with direction of current, the gap bridge direction is vertical with direction of current, two gap bridges with three through holes separately form two shunts thus, and two gap bridges are as the sampling spot of shunt.
The utility model has the advantages that factor that shunt can disturb power frequency at each to offsetting, and sampling is convenient, produces effect stability in batches, can effectively avoid influencing the precision of metering.
