Abstract
The utility model provides a transformer core, which comprises a core formed by overlapping a plurality of square silicon-steel plates. Two sides of the core are provided with core side-yoke tensile plates, and the core and the core side-yoke tensile plates are bound together by using weftless glass fiber adhesive tape. The transformer core adopts the core side-yoke tensile plates outside the core to clamp the same and the weftless glass fiber adhesive tape for binding tightly, and is very convenient in turning and carrying without bending or bulging, thereby reducing operational noise of a transformer. And the core side-yoke tensile plates can be used as positioning components for tensioning an upper clamping element and a lower clamping element of the transformer core and connecting the same by means of tight clamping.
Description
Technical field
The utility model relates to transformer core.
Background technology
Transformer core is formed by many strip silicon steel sheet stacks, because in the closed assembly process, described strip silicon steel sheet horizontal positioned, after finishing, closed assembly needs its upset is erected, there is not mounting coil thereon during the transformer assembling, the mandrel lower bending is heaved, produce the slit, thereby make transformer when operation, produce bigger noise.
Summary of the invention
It is fastening that technical problem to be solved in the utility model provides a kind of colligation, the transformer core that upset is carried easily, noise is lower, be difficult for heaving.For this reason, the utility model is by the following technical solutions:
It comprises iron core, and described iron core is many overlapping square silicon steel sheets, and the both sides of described iron core are provided with iron core return yoke arm-tie, and described iron core is strapped in no latitude glass fibre adhesive tape with iron core return yoke arm-tie.
Owing to adopt the technical solution of the utility model, the utility model clamps iron core at iron core external application iron core return yoke arm-tie, and with the colligation of no latitude glass fibre adhesive tape, make it fastening, very convenient in the upset carrying, crooked bulge phenomenon can not occur, thereby reduce the transformer noise in when operation.Iron core return yoke arm-tie can also will be gone up lower core and clamp continuous as the keeper of transformer core folder from top to bottom tension simultaneously.
Description of drawings
Fig. 1 is an iron core return yoke arm-tie schematic diagram of the present utility model.
Fig. 2 is the side schematic view of Fig. 1.
Fig. 3 is the structural representation before the utility model is used the bondage of no latitude glass fibre adhesive tape.
Fig. 4 is the structural representation that Fig. 3 sees from the side.
Embodiment
Referring to accompanying drawing 1,2,3,4.
The utility model comprises iron core (iron core stem stem) 1, described iron core 1 is the overlapping square silicon steel sheet of polylith, the below of iron core 1 is provided with iron core lower clamping piece 2, the top of iron core 1 is provided with iron core upper clamping piece 3, the both sides of described iron core 1 are provided with iron core return yoke 5, and the both sides of described iron core return yoke 5 is provided with iron core return yoke arm-tie 4.
Iron core return yoke arm-tie 4 is a rectangle, is provided with the shop bolt 6 of location usefulness above.Iron core 1 is strapped in the no latitude glass tape of iron core return yoke arm-tie 2 usefulness.
The utility model clamps iron core 1 and iron core return yoke 5 at iron core return yoke 5 external application iron core return yoke arm-ties 4, and, make it fastening with the colligation of no latitude glass fibre adhesive tape, very convenient in the upset carrying, crooked bulge phenomenon can not occur, thereby reduce the transformer noise in when operation.Iron core return yoke arm-tie 4 can also will clamp continuous up and down as the keeper of transformer core lower clamping piece 2 and upper clamping piece 3 tensions simultaneously.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection range of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection range of the present utility model.
