Abstract
The utility model relates to a vertical magnetic shielding transformer for a smart electric meter. A three-sided U-shaped shielding cover is arranged between a plastic shell and a transformer body; and the three-sided U-shaped shielding cover consists of different sides of a two-sided iron core and a bottom surface. Through the utility model, the magnetic flux leakage of the transformer can be greatly reduced, the interference of the transformer on the devices of an electric energy meter is eliminated, and the measurement precision of the electric energy meter is further improved.
Description
Technical field
The utility model relates to the intelligent electric meter field transformer.
Background technology
The ordinary electronic transformer leakage field phenomenon can occur when work, the components and parts around disturbing in electric energy meter, mainly cause interference to computation chip and shunt, affect electrical energy meter accuracy.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of intelligent electric meter that can address the above problem vertical magnetic shielded transformer.
The utility model is by the following technical solutions: intelligent electric meter vertical magnetic shielded transformer, between plastic casing and transformation body, be provided with three U-shaped radomes, and these three U-shaped radomes are two sides iron core heteropleural and bottom surface.
Between plastic casing and transformation body radome is set, can reduces the leakage field of transformer, eliminating transformer is to the interference of electric energy meter components and parts, thereby further improved the certainty of measurement of electric energy meter.Disturbing three U-shaped iron-clads of employing in the not serious situation, can reduce cost.
Preferably, these three U-shaped radomes are three U-shaped iron-clads, adopt iron-clad high as the shielding material magnetic permeability, and shield effectiveness is good.
The beneficial effects of the utility model are: the utility model can reduce leakage field by between the plastic casing of intelligent electric meter transformer and transformation body three U-shaped radomes being set, and reduces the interference of components and parts on every side.Disturbing three U-shaped iron-clads of employing in the not serious situation, can reduce cost.
