Abstract
The invention relates to the technical field of transformers, and discloses an electronic transformer. The electronic transformer comprises a magnetic core, the periphery of the magnetic core is covered with adhesive tape, and the side of the magnetic core is covered with adhesive tape. Only the side, close to pins, of the magnetic core is covered with the adhesive tape. The periphery and the side of the magnetic core of the transformer are covered with the adhesive tape, the pins of the transformer can be isolated effectively, the creep age distance of the magnetic core and the pins of the transformer is increased, the safety performance of the transformer is improved, the insulation requirement for the design can be met, and then the needs of occasions with high voltages are met.
Description
Technical field
The present invention relates to transformer technology field, relate in particular to a kind of electronic transformer.
Background technology
At present, use electronic transformer product bag magnetic core adhesive tape time, the general paramagnetic core peripheral direction that adopts is wrapped up a circle adhesive tape 2, as shown in Figure 1, its effect is by fixing magnetic core 1, but coated incomplete, for the sidepiece of magnetic core 1 coated less than, the creepage distance that magnetic core is required stitch safety is inadequate, does not reach the insulating requirements of design, cannot meet high-tension occasion needs.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is how to increase the creepage distance that in electronic transformer, magnetic core requires stitch safety.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides a kind of electronic transformer, comprise magnetic core, the periphery of described magnetic core is enclosed with adhesive tape, and the sidepiece of described magnetic core is also enclosed with adhesive tape.
Further, described magnetic core is enclosed with adhesive tape at the sidepiece near stitch.
Further, described magnetic core adhesive tape peripheral and sidepiece is equipped with one or more layers.
Further, the thickness of the adhesive tape of described magnetic core periphery and sidepiece is all greater than 0.025mm.
(3) beneficial effect
A kind of electronic transformer provided by the invention, the periphery of magnetic core and sidepiece all adopt adhesive tape to wrap up, isolating transformer stitch effectively, the creepage distance of magnetic core of transformer and stitch is strengthened, improve the safety performance of this transformer, can reach the insulating requirements of design, and then meet high-tension occasion needs.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 2, a kind of electronic transformer of the present invention, comprises magnetic core 10, and the periphery of this magnetic core 10 is enclosed with adhesive tape 20, and the sidepiece of magnetic core 10 is also enclosed with adhesive tape 20.Also adopt adhesive tape 20 to wrap up at the sidepiece of magnetic core 10, with isolating transformer stitch, the creepage distance of magnetic core of transformer and stitch is strengthened, improved the safety performance of this transformer.
In order to economize on resources, preferably, 10 of magnetic cores are enclosed with adhesive tape 20 at the sidepiece near stitch 30, as shown in Figure 3 and Figure 4, wherein, the structural representation that Fig. 3 is vertical transformer, Fig. 4 is the structural representation of horizontal type transformer, and the stitch of the horizontal type transformer in Fig. 4 is L-type.
The periphery of magnetic core 10 and the adhesive tape of sidepiece 20 are equipped with one or more layers, are preferably multilayer, creepage distance stitch safety being required to increase further magnetic core.The thickness of the adhesive tape of magnetic core periphery and sidepiece is all greater than 0.025mm.
The present invention all adopts adhesive tape to wrap up at periphery and the sidepiece of magnetic core, isolating transformer stitch effectively, strengthens the creepage distance of magnetic core of transformer and stitch, has improved the safety performance of this transformer, can reach the insulating requirements of design, and then meet high-tension occasion needs.And further, can overcome abnormal sound and noise that high voltage place produces, the more important thing is, the stitch of transformer can not discharge to magnetic core, avoids producing high voltage arc phenomenon.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
Claims (4)
1. an electronic transformer, comprises magnetic core, and the periphery of described magnetic core is enclosed with adhesive tape, it is characterized in that, the sidepiece of described magnetic core is also enclosed with adhesive tape.
