Abstract
The utility model provides a main board of an electric energy meter. The main board comprises a base plate, wherein a voltage sampling circuit is arranged on the base plate and positioned on the upper surface layer of the base plate. The voltage sampling circuit originally arranged on the bottom layer is changed to be arranged on the upper surface layer, and for the reason that the contact space of the upper surface layer of the main board of the electric energy meter is relatively larger, the humidity of the upper surface layer is lower than that of the bottom layer in case of limited ventilation condition after the main board of the electric energy meter is installed in the electric energy meter, so that the purpose of reducing the metering error of the electric energy meter is realized, and the influence of the climatic factors on the electric energy meter is lowered.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of mainboard of electric energy meter.
Background technology
At present, on the mainboard of electric energy meter, its voltage sampling circuit all is arranged on the bottom of mainboard, like this, mainboard use be installed in the electric energy meter after, in some weathers humid region comparatively, the influence of the factors such as ventilation effect of being ventilated, the bottom and the humidity between the electric energy meter of mainboard are higher, cause the error in dipping of electric energy meter easily.
The utility model content
Technical problem to be solved in the utility model is, a kind of mainboard of electric energy meter is provided, and it can reduce the influence of humidity to electric energy meter, reduces the error in dipping of electric energy meter.
For solving the problems of the technologies described above, the mainboard of the electric energy meter that the utility model provides, it comprises substrate, comprises voltage sampling circuit on the described substrate, described voltage sampling circuit is positioned at the upper epidermis of substrate.
After adopting above structure, the mainboard of the utility model electric energy meter compared with prior art has the following advantages:
Changed into and be arranged on upper epidermis originally being arranged on voltage sampling circuit on the bottom, after the mainboard of electric energy meter is installed in the electric energy meter, because the space that upper epidermis contacted of the mainboard of electric energy meter is relatively large, under the ventilation condition condition of limited, the humidity of upper epidermis is lower than bottom humidity, so just can reach the purpose that reduces the electric energy meter error in dipping, make climatic factor lower the influence of electric energy meter.
