Abstract
The utility model relates to a horizontal magnetic shielding transformer for a smart electric meter. A five-sided shielding cover is arranged between a plastic shell and a transformer body; and a five-sided iron shell is arranged on the five-sided shielding cover, thus 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 the horizontal magnetic shielding transformer of a kind of intelligent electric meter that can address the above problem.
The utility model is by the following technical solutions: the horizontal magnetic shielding transformer of intelligent electric meter is provided with five radomes between plastic casing and transformation body.
The ordinary electronic transformer leakage field phenomenon can occur when work, the components and parts around disturbing cause interference to computation chip and shunt, affect electrical energy meter accuracy.Five radomes are set between plastic casing and transformation body, can greatly reduce 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.
Preferably, these five radomes are five 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 is by arranging radome between the plastic casing of intelligent electric meter transformer and transformation body, the leakage field phenomenon of transformer reduces greatly, the interference of components and parts is on every side also reduced thereupon, can reach the standard that the client accepts.
