Abstract
The utility model relates to an insulating and supporting stay made by means of moulding epoxy resin and used for low tension coil of dry-type transformer. The two side faces of the stay adjoining an iron core are designed as a right angle and the part of the low tension coil near the transformer is designed as a straight line. The section is in the shape of ladder. The utility model has advantage that production cost is effectively reduced because a fire resistant rubber material formed by moulding is employed. After formed by moulding, the stay is fixed on the iron core with fire resistant glue and lower tension coil is fixed by pressing in the stay when setting up. The disadvantages such as resonance, noise occur during operation are overcome a flexible connection is formed between the iron core and the low tension coil, meanwhile, damages on the iron core of the transformer and low tension coil caused by violent punch when ;pumping down the support plate can be eliminated.
Description
Technical field
The utility model relates to a kind of insulation of epoxy cast dry transformer low-voltage coil and stay of stretching of being used for.Belong to the transformer technology field.
Background technology
Usually between the low-voltage coil of epoxy cast dry transformer and iron core, adopt fagging to insulate and stretching with certain thickness and width.Being connected yet belong to hard between the iron core when adopting this mode in the transformer and the coil, is hard the connection between iron core and the coil, and this can resonate for transformer when operation, produces certain noise.Resonance taking place and produce noise and bring many influences can for the performance of product, all can bring in various degree influence as reliability of products, fail safe etc.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of through the improved insulation of epoxy cast dry transformer low-voltage coil and the stay of stretching of being used for.It is connected hard between the iron core in the transformer of the prior art and the coil to change between transformer core and the low-voltage coil and belongs to soft being connected, to reach the noise that reduces transformer and to avoid transformer that problems such as resonance can take place when the operation.
Technical solution of the present utility model: its structure is that the insulation and the stretching of epoxy cast dry transformer low-voltage coil is designed to the right angle with stay near two sides 1,2 unshakable in one's determination, is designed to straight line near low voltage winding in transformers part 3.The insulation of epoxy cast dry transformer low-voltage coil and stretching are stepped with the cross section of stay.
Advantage of the present utility model: owing to adopt a kind of resistant to elevated temperatures elastomeric material, and be to pass through mould molding, effectively reduced production cost, elastomeric material is fixed on stay on the iron core with resistant to elevated temperatures glue after by mould molding, after low-voltage coil is pressed into stay when suit just stretching low-voltage coil, make between iron core and the low-voltage coil and formed a kind of soft being connected.What form between iron core and the low-voltage coil is a kind of soft connection, can resonate, produce defectives such as noise so it has effectively overcome prior art when operation.Simultaneously, can avoid existing and squeeze into the technology of fagging because fierce impacting to transformer core and low-voltage coil causes damage.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
Among the figure 1, the 2nd is near two sides, the 3rd unshakable in one's determination, near the low-voltage coil medial surface.
Embodiment
Contrast accompanying drawing, its structure are that the insulation and the stretching of epoxy cast dry transformer low-voltage coil is designed to the right angle with stay near two sides 1,2 unshakable in one's determination, are designed to straight line near low-voltage coil medial surface 3.The insulation of epoxy cast dry transformer low-voltage coil and stretching are stepped with the cross section of stay.
According to present manufacturing process unshakable in one's determination, the core limb cross section be one multistage trapezoidal, so this stay is designed to right-angle structure near core side, can better fully contact with iron core, keep stressed even; Low-voltage coil inside is a disc, regards straight line as but can be similar at a less end circular arc, so this stay is a straight line near the low-voltage coil partial design, also can fully contact its basic configuration such as accompanying drawing 1. with low-voltage coil
This novel stay adopts a kind of resistant to elevated temperatures elastomeric material simultaneously, pass through mould molding, with resistant to elevated temperatures glue stay is fixed on the iron core then, after during the low-voltage coil suit stay being pressed into just stretching low-voltage coil, form a kind of soft being connected between iron core and the low-voltage coil simultaneously.
Claims (1)
1, the insulation of epoxy cast dry transformer low-voltage coil and stretching stay, it is characterized in that at right angles near two sides (1,2) design unshakable in one's determination, be designed to straight line near low-voltage coil medial surface (3), the insulation of epoxy cast dry transformer low-voltage coil and stretching are stepped with the cross section of stay.
