Abstract
The utility model relates to an anti-interference safety transformer and belongs to the field of power transformation devices. The anti-interference safety transformer comprises a framework and a magnetic core. The magnetic core is located in a coil. The anti-interference safety transformer is characterized in that bosses with the height ranging from 12 mm to 14 mm are machined on the two sides of the framework respectively, wherein the ends of the two bosses are respectively provided with pins; wire slots are machined in the inner sidewalls, on one side of the pins, of the bosses, and protruding posts are machined on the outer sidewalls, on the other side of the pins, of the bosses; varnished wires of the coil are embedded in the wire slots, wound around the protruding posts and welded to the pins. According to the anti-interference safety transformer, the safety distance between the pins and the wire winding portions is increased, and poor withstand voltage less occurs; influences of oscillation generated by a circuit board under strong magnetic interference on normal operation of the transformer are reduced, and the condition of abnormal operation, caused by electromagnetic interference, of an electric energy meter is prevented.
Description
Technical field
The utility model relates to transformation device field, at length says it is the anti-interference safety transformer that a kind of electric energy meter uses.
Background technology
Well-known: at present in order to meet the accuracy of ammeter counting, farthest minimizing ammeter inside is subject to the requirement of the interference of external electromagnetic environment, must there be the components and parts of the anti-interference structure adapting with it supporting, power transformer is the most difficult one of jamproof device of realizing wherein, wherein ammeter requires also obviously restricting the manufacturing of transformer to the high safety of transformer, it is low that the safety control mode operating efficiency of fly line is drawn in employing at present, and production capacity is lower.
Summary of the invention
The purpose of this utility model is just to overcome the deficiencies in the prior art, and a kind of anti-interference safety transformer is provided, and increases the safety distance of pin and winding portion, has reduced withstand voltage bad generation; Reduce circuit board and be subject to the concussion of strong magnetic disturbance generation to affect the normal work of transformer, prevented the electric energy meter operation irregularity situation that brought by electromagnetic interference.
The utility model adopts following technical solution: a kind of anti-interference safety transformer, comprise skeleton and magnetic core, magnetic core is positioned at coil, it is characterized in that, skeleton both sides are processed with respectively the highly boss for 12-14 millimeter, and two boss ends are separately installed with pin, are processed with wire casing on the boss madial wall of pin one side, on the boss lateral wall of pin opposite side, be processed with projection, the enamelled wire of coil is entrenched in wire casing and after walking around projection and is welded on pin.
The beneficial effects of the utility model are that the safety distance of increase pin and winding portion, has reduced withstand voltage bad generation; Reduce circuit board and be subject to the concussion of strong magnetic disturbance generation to affect the normal work of transformer, prevented the electric energy meter operation irregularity situation that brought by electromagnetic interference.
