Abstract
The utility model belongs to the electronic equipment field, and specifically relates to an antimagnetic three-phase electric energy meter with excellent effect; the antimagnetic three-phase electric energy meter comprises a meter housing; the bottom portion of the meter housing is a bottom plate having a shield cover; the bottom portion of the shield cover is provided with a first iron plate and a second iron plate; a gap is arranged between the first iron plate and the second iron plate. The integrated shield cover is fixed on the bottom plate; the first iron plate and the second iron plate on the shield cover are connected through a rivet; the gap is arranged between the first iron plate and the second iron plate so as to thoroughly stop strong magnetic interferences, thereby solving magnetic force interference problems. A surface of the shield cover is coated with chemical paint, so basic insulation can be realized to ensure safety.
Description
Technical field
The utility model belongs to electronic device field, specifically relates to a kind of respond well antimagnetic three-phase electric energy meter.
Background technology
At present, intelligent electric energy meter is universal in China, but has found some problems in the process using in reality, and wherein topmost problem is exactly the interference problem of stationary magnetic field to electric energy meter.
It is the built-in electric energy meter of on-load switch that the intelligent electric energy meter that state nets now has more than 70%, and now the intelligent electric energy meter in market all uses magnetic latching relay as the built-in on-load switch of electric energy meter, in the time that the external world is used 50mm*50mm*50mm magnetic force, for permanent magnet more than 200mT, electric energy meter is applied to stationary magnetic field interference, use the power-off of cannot normally operating a switch of the electric energy meter of magnetic latching relay, cause the illegal user of part to adopt this kind of illegal electricity consumption of section.
In the time that the external world is used magnetic force, will have influence on the normal work of three-phase meter internal relay, cause three-phase electric energy meter metering inaccurate, affect the normal use of electric power.
Utility model content
The technical problems to be solved in the utility model is to provide the antimagnetic three-phase electric energy meter that a kind of thoroughly isolated magnetic force disturbs.
Content of the present utility model is to comprise watchcase, and described watchcase bottom is base plate, on described base plate, is provided with radome, and the bottom of described radome is provided with the first iron plate and the second iron plate, between described the first iron plate and the second iron plate, is provided with gap.
Described the first iron plate is connected by web member with the second iron plate.
Described web member is rivet.
The beneficial effects of the utility model are, the utility model is by being fixed on the radome of integral type on base plate, the first iron plate on radome is connected by rivet with the second iron plate, gapped between the first iron plate and the second iron plate, can thoroughly prevent the interference of strong magnetic, solve the problem that magnetic force disturbs.The surface of radome of the present utility model is coated with chemical paint vehicle, can accomplish basic insulation, ensures safety.
