Abstract
The utility model provides a fixed toroidal transformer's novel device, includes via having a perfect understanding screw rod fastening last gland on toroidal transformer and gland down, goes up the gland including the gland support arm on downthehole last gland type post of toroidal transformer type and a plurality of of pegging graft, upward gland branch arm end is first suppresses on toroidal transformer's up end, down the gland is including the gland support arm under the downthehole lower gland type post of toroidal transformer type and a plurality of of pegging graft, and lower gland branch arm end head is suppressed on toroidal transformer's lower terminal surface. The utility model discloses increase the appearance of upper and lower gland, make the middle part that suppression point between gland and the toroidal transformer coil shifted terminal surface under toroidal transformer by type hole border, this region is broad, the wire winding is leveled, the pressure that can bear is also big, on keeping whole circular shape basis, circumference evenly distributed is pressed to the gland support arm from top to bottom, reduce materials and weight in the proof strength, insulating damage has been solved, enameled wire pressurized short circuit scheduling problem, the obvious enhancement of stability of fastening back transformer.
Description
Technical field
The utility model belongs to the fixture technical field of toroidal transformer, specifically relates to a kind of new device of stationary annular transformer.
Background technology
High-power annular transformer in AC voltage regulator is when installing fixing, and usually adopt the mode that in the middle of upper lower cover, through screw rod is fastening, the material of upper lower cover is high strength glass fiber reinforced plastic.Referring to Fig. 1, traditional upper lower cover is disc, its external diameter is slightly larger than the nibs of toroidal transformer, on when fastening, the contact area of lower cover and toroidal transformer is little, and the pressure that the enamelled wire of nibs periphery is subject to is very large, and the wire of this position is many exactly, the coiling number of plies is many, very easily cause the damage in insulation between enamelled wire, happen occasionally in actual production is sold, there is potential safety hazard; And this structure can cause transformer discontinuity, in transportation, easily cause the impaired distortion of outside iron-clad.
Summary of the invention
The utility model mainly solves the technical problem existing for above-mentioned prior art, provides a kind of new device of stationary annular transformer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of new device of stationary annular transformer, comprise and be fastened on upper press cover on toroidal transformer and lower cover via through screw rod, described upper press cover comprises and is plugged on upper press cover type post in toroidal transformer nibs and several upper press cover support arms, and upper press cover support arm termination is compressed on the upper surface of toroidal transformer; Described lower cover comprises being plugged on and presses down cap-type post and several lower cover support arms in toroidal transformer nibs, and lower cover support arm termination is compressed on the lower surface of toroidal transformer.
As preferably, the medial surface of described upper press cover support arm termination is provided with lower convex platform shoulder, and this lower convex platform shoulder is compressed on the upper surface of toroidal transformer; The medial surface of described lower cover support arm termination is provided with epirelief shoulder, and this epirelief shoulder is compressed on the lower surface of toroidal transformer.
As preferably, described upper press cover support arm is provided with some upper press cover support arm fabrication holes, described lower cover support arm is provided with some lower cover support arm fabrication holes, this fabrication hole can increase the elasticity of upper lower cover support arm, make transformer discontinuity time fastening, not easily cause in transportation outside iron-clad impaired and distortion.
The profile of upper lower cover strengthens by the utility model, the point of the compacting between gland and toroidal transformer coil is made to be transferred to the middle part of toroidal transformer lower surface by nibs edge, this region is broad, coiling is smooth, the pressure that can bear is also large, on the basis keeping unitary circular, upper lower cover support arm is circumferentially uniformly distributed, and can reduce materials and weight while proof strength.Through the trial production of nearly a year, the problems such as damage in insulation, the short circuit of enamelled wire pressurized were all well solved, and the transformer stability after fastening is obviously strengthened.Therefore the utility model has the features such as structure is simple, reasonable in design.
Accompanying drawing explanation
Fig. 1 is a kind of fixture structure schematic diagram of toroidal transformer in prior art;
Fig. 2 is a kind of structural representation of the present utility model.
In figure, 1-toroidal transformer, 2-upper press cover, 21-upper press cover support arm, 22-upper press cover type post, 23-upper press cover support arm termination, 24-upper press cover support arm fabrication hole, 3-lower cover, 31-lower cover support arm, 32-presses down cap-type post, 33-lower cover support arm termination, 34-lower cover support arm fabrication hole, 4-toroidal transformer nibs.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 2, a kind of new device of stationary annular transformer, comprise and be fastened on upper press cover on toroidal transformer and lower cover via through screw rod, wherein upper press cover comprises and is plugged on upper press cover type post in toroidal transformer nibs and several upper press cover support arms, upper press cover support arm termination is compressed on the upper surface of toroidal transformer, specifically the medial surface of upper press cover support arm termination is provided with lower convex platform shoulder, and this lower convex platform shoulder is compressed on the upper surface of toroidal transformer; Lower cover comprises being plugged on and presses down cap-type post and several lower cover support arms in toroidal transformer nibs, lower cover support arm termination is compressed on the lower surface of toroidal transformer, specifically the medial surface of lower cover support arm termination is provided with epirelief shoulder, and this epirelief shoulder is compressed on the lower surface of toroidal transformer.Upper press cover support arm is provided with some upper press cover support arm fabrication holes in addition, lower cover support arm is provided with some lower cover support arm fabrication holes, this fabrication hole can increase the elasticity of upper lower cover support arm, makes transformer discontinuity time fastening, not easily cause in transportation outside iron-clad impaired and distortion.
The profile of upper lower cover strengthens by the utility model, the point of the compacting between gland and toroidal transformer coil is made to be transferred to the middle part of toroidal transformer lower surface by nibs edge, this region is broad, coiling is smooth, the pressure that can bear is also large, on the basis keeping unitary circular, upper lower cover support arm is circumferentially uniformly distributed, and can reduce materials and weight while proof strength.Through the trial production of nearly a year, the problems such as damage in insulation, the short circuit of enamelled wire pressurized were all well solved, and the transformer stability after fastening is obviously strengthened.Therefore the utility model has the features such as structure is simple, reasonable in design.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection range of the present utility model.
