Abstract
The utility model belongs to the technical field of high-efficiency transformers and particularly relates to a PQ-type high-frequency transformer framework with a large safe distance. The PQ-type high-frequency transformer framework with the large safe distance comprises a framework middle column, a secondary winding outlet guide part and a secondary winding outlet turning corner groove. A magnetic core cavity is formed in the framework middle column. The PQ-type high-frequency transformer framework with the large safe distance is characterized in that the width of the secondary winding outlet guide part is 7.6mm, and the wire diameter of the secondary winding wire is generally 1.2-1.3mm. Therefore, the distance between the secondary winding outlet end and the secondary winding outlet turning corner groove is about 6.3mm and larger than the existing distance of 3.4mm. The creep distance and electric clearance are enabled to be increased, and use is safer. The PQ-type high-frequency transformer framework with the large safe distance is simple in structure, high in production efficiency, strong in applicability and low in cost and meets national electrical safety requirements.
Description
Technical field
The utility model belongs to the high frequency transformer technical field, relates in particular to PQ type high-frequency transformer skeleton.
Background technology
PQ type high-frequency transformer skeleton is the winding bracket of high-power high-frequency transformer, along with renewal and the upgrading of the electrical safety laws and regulations of various countries, electric clearance and the creepage distance of transformer is required also to strengthen thereupon.General PQ type high-frequency transformer skeleton in the market, after completing transformer winding, its electric clearance safe distance is only 3.9mm, and creepage distance is only 4.3mm, and fail safe is relatively poor.
Summary of the invention
The purpose of this utility model is that to provide safe distance more large, uses saferly, satisfies the transformer framework of national electrical safety requirement.
Provide for this reason have large safe distance PQ type high-frequency transformer skeleton, comprise skeleton center pillar, secondary winding outlet guide portion and secondary winding outlet corner slots, the skeleton center pillar is provided with the magnetic core cavity, it is characterized in that, secondary winding outlet guide portion width is 7.6mm.
The utility model secondary winding outlet guide portion width is 7.6mm, and the wire diameter of secondary winding outlet is generally 1.2～1.3mm, therefore the distance of 6.3mm is approximately arranged from the secondary winding leading-out terminal to secondary winding outlet corner slots, distance greater than existing 3.4mm, make creepage distance and electric clearance increase, use safer.The utility model is simple in structure, and production efficiency is high, satisfies the requirement of national electrical safety, and applicability is strong, and is with low cost.
Description of drawings
Fig. 1 is the transformer framework stereogram.
Fig. 2 is with make the vertical view of the transformer that turns to as the transformer framework of Fig. 1.
Fig. 3 is the left view of Fig. 2.
Embodiment
As Fig. 1, have large safe distance PQ type high-frequency transformer skeleton comprise skeleton center pillar 3, secondary winding outlet guide portion 1 and three secondary winding outlet corner slots 2, skeleton center pillar 3 is provided with magnetic core cavity 4 and is used for the assembling magnetic core.make PQ type high frequency transformer such as Fig. 2 with this transformer framework, draw secondary winding outlet 6 from armature winding line bag 5 ends, secondary winding outlet guide portion 1 width is 7.6mm, make as shown in Figure 3, the distance of 6.3mm is approximately arranged from secondary winding leading-out terminal 7 to secondary winding outlet corner slots 2, secondary winding outlet corner slots 2 length are 4.2mm, therefore creepage distance is 6.3mm+4.2mm=10.5mm, 8 electric clearances from secondary winding leading-out terminal 7 to secondary winding fly line hanging wire pin are about 7.35mm, creepage distance and electric clearance greater than prior art, use safer, satisfy the requirement of national electrical safety.
