Abstract
The invention discloses a fixing structure of a transformer iron core. The structure comprises a lower bottom board and an upper pressing plate which are arranged on an iron core and clamp the iron core. The lower bottom board and the upper pressing plate are connected through a fixing plate. A cylindrical groove is arranged on the position corresponding to the upper pressing plate and the lower bottom board. Two ends of the fixing plate are provided with holding plugs matched with the shape of the groove, and the plugs are respectively held in the groove. The fixing structure of a transformer iron core solves defects that an existing transformer iron core is not stable through a fixing method of using a nut fixing structure. The fixing structure of a transformer iron core can fix the iron core stably, and projection portions would not exist on two ends, preventing operating personnel from collision accidents. Since screws used for fixing are screwed in a device, the screws are unscrewed caused by curiousness of a person is prevented.
Description
Technical field
The invention belongs to electrical equipment technical field, be specifically related to consolidating of a kind of transformer coreFixed structure.
Background technology
In the electrical network of power delivery, various transmission facility shareds electric energy are transported to endThe function of end subscriber, and transformer turns then establishing to terminal use's transmission of electricity of voltage as high pressureStandby, it is bearing last terminal that electric energy is registered one's residence. Present transformer generally byIron core and coil windings are entwined, and iron core mainly folds by top board and lower shoe,And process screw rod at the two ends of top board and lower shoe, and process at the two ends of fixed headThe through hole adapting with it is inserted in screw rod and is then fixed by screwing in nut, this solidDetermine mode and make the two ends of top board and lower shoe all can give prominence to a part, so not only mayCan cause operating personnel to collide with injured, simultaneously the fixing nut in its screw rod two ends also likely byChild screws out the shortcoming that causes iron core solid failure because playing.
Summary of the invention
The object of the present invention is to provide a kind of fixed structure of transformer core, solved existingThe unsettled shortcoming of fixed form that some transformer cores exist by the fixing structure of nut.
The technical solution adopted in the present invention is: a kind of fixed structure of transformer core, bagDraw together be arranged at iron core and clamping iron core lower shoe and top board, top board and lower shoe itBetween be connected by fixed head, top board and lower shoe mutually corresponding position are provided with cylindricalGroove, the two ends of fixed head are provided with the accommodating plug and the difference that adapt with groove shapesBe placed in groove.
Feature of the present invention is also,
Groove outside in comprises the containing groove and the fixing threaded hole that are connected, fixing threaded hole toolThere is internal thread.
On accommodating plug, offer through hole, on through hole, there is internal thread, in through hole, be installed with spiral shellNail, screw is spun in fixing threaded hole.
Accommodating plug is provided with accommodating for accommodating screw head near one end of screw headStorehouse, accommodating storehouse is connected with through hole.
Fixed head is "] " shape.
Screw is horizontal tail screw or fine stern screw.
The invention has the beneficial effects as follows: the fixed structure solution of a kind of transformer core of the present inventionThe fixed form that the existing transformer core of having determined exists by the fixing structure of nut is unstableShortcoming. The fixed structure of a kind of transformer core of the present invention can be fixed stable iron core,And can there is not ledge in two ends, avoid operating personnel's accident of colliding with, andBecause the screw of fixing use is spun on device inside, avoid having people because of curious showing of unscrewingResemble generation.
Brief description of the drawings
Fig. 1 is the structural representation of the fixed structure of a kind of transformer core of the present invention.
In figure, 1. top board, 2. lower shoe, 3. fixed head, 4. groove, 5. iron core, 31. holdPut plug, 32. through holes, 33. screws, 34. accommodating storehouses, 41. containing grooves, 42. fixing threaded holes.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
The structure of the fixed structure of a kind of transformer core provided by the invention as shown in Figure 1,A fixed structure for transformer core, comprises and is arranged at iron core 5 and clamping iron core 5Lower shoe 2 and top board 1, be connected by fixed head 3 between top board 1 and lower shoe 2,Top board 1 and lower shoe 2 are provided with cylinder shape groove 4, fixed head 3 in the position of correspondence mutuallyTwo ends be provided with the accommodating plug 31 adapting with groove 4 shapes and be placed in respectively recessedIn groove 4.
Groove 4 outside in comprises the containing groove 41 and the fixing threaded hole 42 that are connected, fixingScrew 42 has internal thread.
On accommodating plug 31, offer through hole 32, on through hole 32, there is internal thread, through hole 32Inside be installed with screw 33, screw 33 is spun in fixing threaded hole 42.
Accommodating plug 31 is provided with for 33, accommodating screw near one end of screw 33 headsThe accommodating storehouse 34 of portion, accommodating storehouse 34 is connected with through hole 32.
Fixed head 3 is "] " shape.
Screw 33 is horizontal tail screw or fine stern screw.
When use, between top board 1 and lower shoe 2, clamp iron core 5, then fixed head 3The accommodating plug 31 at two ends inserts containing groove 41 inside on groove 4, and then precession is logicalIt is solid that screw 33 in hole 32 spins screw 33 and the inner most fixing threaded hole 42 of groove 4Fixed, and because the head of screw 33 is greater than rotary screw portion, therefore accommodating storehouse 34 is setMake screw 33 heads be positioned at accommodating storehouse 34, avoid people to come in joyful or other reasonsScrew out screw 33, screw 33 can be selected various forms, and the afterbody of screw 33 canBeing the horizontal tail screw of columniform screw shaped, can be also fine stern screw, as long as fixing threaded hole42 shape adapts just passable with it.
By the way, the fixed structure of a kind of transformer core of the present invention has solved existingThe unsettled shortcoming of fixed form that some transformer cores exist by the fixing structure of nut.The fixed structure of a kind of transformer core of the present invention can be fixed stable iron core, and twoCan there is not ledge in end, avoided operating personnel's accident of colliding with, and owing to consolidatingThe screw of determining use is spun on device inside, has avoided having people because of curious phenomenon generation of unscrewing.
