Description
Technical field
The utility model relates to a kind of network transformer.
Background technology
transformer utilizes mutual inductance principle to change alternating voltage, is made up of primary coil, secondary coil and iron core.The structure of existing transformer core comprises multiple lamination, and lamination comprises the lamination element that section is " I " and " E ", and I lamination and E lamination form " day " font lamination.The center arm of E lamination is positioned at the center of bobbin.Because lamination is the superposition that interlocks one by one, namely after the I lamination of ground floor and the docking of E lamination, the lamination of the second layer is assembled on iron-core element in the opposite direction, and namely the neighbouring of I lamination is E lamination.But, this structure in use there will be problem, namely must ensure the fixing of I lamination and E lamination position, because I lamination and E lamination are contact, it easily goes wrong, the i.e. movement of I lamination and the easy occurrence positions of E lamination, make both loose contacts, be similar to iron core and reduce, reactance is reduced, power also reduces thereupon, even makes coil heating or burn out time serious.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of network transformer, the Stability Analysis of Structures of its iron-core element, lamination contact stabilization, and Bu easy Fa Sheng Nuo position, avoids the phenomenon such as power reduction or coil heating in use procedure.
The technical scheme in the invention for solving the above technical problem is:
A kind of network transformer, comprise iron-core element, described iron-core element comprises the multiple smooth lamination paralleled be stacked adjacent one another are, skid resistant course is provided with between described lamination, described skid resistant course is arranged porose, described lamination comprises E lamination and forms the second lamination of " day " font with E lamination, be provided with overlapping portion between described E lamination and the second lamination, described overlapping portion comprises the upper superimposed sheets on E lamination/the second lamination and the lower superimposed sheets on the second lamination/E lamination.
The utility model improves prior art, one: between adjacent two laminations, arrange skid resistant course, once laminated sheet package is good, owing to being in impaction state between lamination, skid resistant course makes its not easily the moving of occurrence positions, and lamination is stablized; Its two: due to iron-core element be generally bag paint iron core, use in the environment that pressure is large, mutually push between iron-core element, there is the impaired situation of varnish, varnish damages can cause the situations such as iron core heating, skid resistant course further can play cushioning effect, avoids pushing the situation causing varnish breakage; Its three: at E lamination and the second lamination contact site, overlapping portion is set, overlapping portion is utilized to increase the contact-making surface of E lamination and the second lamination, when the position of E lamination and/or the second lamination is moved and the distance of movement is less than the length of overlapping portion, overlapping portion between E lamination and the second lamination still contacts well, strengthens the stability of core structure.Namely upper superimposed sheets and lower superimposed sheets press the likeness in form overlapping placement up and down of lamination.
As preferably, the section of the second described lamination is " E " font.
Further, the length of described upper superimposed sheets and lower superimposed sheets has 0.1 centimetre at least.Be in impaction state between lamination, too great Nuo position can not occur between E lamination and the second lamination, but during in order to ensure E lamination and/or the second lamination Fa Sheng Nuo position, overlapping portion contact is good, and the length of upper superimposed sheets and lower superimposed sheets has 0.1 centimetre at least.
Further, the length of described upper superimposed sheets and lower superimposed sheets is 0.2 centimetre.
As preferably, the hole on described skid resistant course has multiple.
To sum up, the beneficial effects of the utility model are:
1, the utility model arranges skid resistant course between adjacent two laminations, it not only can make lamination not easily move, strengthen the stability of core structure, the situation of the varnish breakage that iron core excessive compression also can be avoided to cause, avoids power reduction or coil heating burnout phenomenon in use procedure.
2, the utility model arranges overlapping portion at E lamination and the second lamination contact site, overlapping portion is utilized to increase the contact-making surface of E lamination and the second lamination, when the position of E lamination and/or the second lamination is moved and the distance of movement is less than the length of overlapping portion, overlapping portion between E lamination and the second lamination still contacts well, strengthens the stability of core structure.
