Description
Technical Field
The utility model relates to a transformer technical field, concretely relates to transformer coil skeleton of high electrical strength.
Background
At present, a transformer is a very common electric device, and the most basic type of the transformer includes an iron core (a silicon steel sheet group) and a coil wound on a framework. The iron core and the framework need to be provided with relevant wiring terminals for proper electrical connection of external wires and coils. The structure design of the existing transformer coil framework is unreasonable, the electrical clearance of the transformer coil framework is small, and the creepage distance is small, so that the transformer coil framework has the defects of complex structure, unreliable performance and low electrical strength.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, long service life's high electrical strength's transformer coil skeleton.
In order to realize the above purpose, the utility model discloses a transformer coil skeleton of high electric intensity, including the coil skeleton body, the coil skeleton body on be provided with the quad slit that is used for placing the iron core, the both ends of coil skeleton body on be provided with a spacing turn-ups respectively, be formed with the storage tank that is used for the coiling coil between two spacing turn-ups, two spacing turn-ups one side on correspond the storage tank punishment and do not be provided with an annular step.
The beneficial effect of above-mentioned structure is: the annular steps are arranged on the limiting flanges of the transformer coil framework, the creepage distance of the input side and the output side of the coil can be increased by the annular steps on the two limiting flanges, and the improvement of the insulation performance of the transformer coil framework is facilitated, so that the transformer coil framework has the advantages of simple structure, stable and reliable performance, long service life and high electrical strength.
Particularly, a plurality of reinforcing ribs are respectively arranged on the other sides of the two limiting flanging edges. The reinforcing ribs can enhance the strength of the limiting flanging, so that the overall strength of the transformer coil framework can be enhanced, and the service life of the transformer coil framework can be prolonged.

Detailed Description
As shown in fig. 1-3, the embodiment of the utility model provides a transformer coil skeleton of high electric strength, including coil skeleton body 10, coil skeleton body 10 on be provided with the quad slit 101 that is used for placing the iron core, coil skeleton body 10's both ends on be provided with a spacing turn-ups 11 respectively, be formed with the storage tank 100 that is used for the coiling coil between two spacing turn-ups 11, one side of two spacing turn-ups 11 on correspond storage tank 100 punishment and do not be provided with an annular step 111. And a plurality of reinforcing ribs 112 are respectively arranged on the other sides of the two limiting flanges 11. The reinforcing ribs can enhance the strength of the limiting flanging, so that the overall strength of the transformer coil framework can be enhanced, and the service life of the transformer coil framework can be prolonged.
The annular steps are arranged on the limiting flanges of the transformer coil framework, the creepage distance of the input side and the output side of the coil can be increased by the annular steps on the two limiting flanges, and the improvement of the insulation performance of the transformer coil framework is facilitated, so that the transformer coil framework has the advantages of simple structure, stable and reliable performance, long service life and high electrical strength.
