Abstract
The utility model discloses an oil-immersed transformer coil pressing device, which comprises a nail pressing plate, a nail pressing bolt and a nail pressing gasket, wherein the nail pressing plate is horizontally fixed on a transformer core clamping piece, and is provided with a tapped hole; the nail pressing bolt is in threaded connection with the nail pressing plate; the lower end of the nail pressing bolt is fixedly connected with the nail pressing gasket; and the nail pressing gasket is pressed on a pressing plate of a transformer coil. Compared with a conventional coil pressing mechanism, the oil-immersed transformer coil pressing device saves pressure riveting nuts fixed on the nail pressing plate; and the tapped hole is directly reserved on the nail pressing plate, and the nail pressing bolt is in threaded connection with the nail pressing plate, and is screwed in, so that the nail pressing gasket connected to the lower end of the nail pressing bolt gradually presses the pressing plate to press the transformer coil to realize the fixation of a transformer body.
Description
Technical field
The utility model relates to transformer manufacture technology, especially relates to a kind of oil-filled transformer line ball coil apparatus.
Background technology
The inside of oil-filled transformer must keep device tight, and especially the inner compactor body of high-power transformer needs to realize purpose by the line ball loop mechanism on the transformer core folder often.Usually the inner line ball loop mechanism that adopts of transformer is by pressing the cooperation that spins of oncomelania bolt and self-clinching nut, again by pressing the bolted pressure washer of nail to press down pressing plate, realize compressing by pressing plate to the device body, and after used pressure oncomelania mother needs to make in advance on the pressure nail-plate, be installed in again and press in the nail-plate guide hole, so just increased the production process and the installation steps of line ball loop mechanism, strengthened man power and material's input, be unfavorable for saving energy and reduce the cost, provide and produce and operating efficiency.
The utility model content
The purpose of this utility model is to provide a kind of oil-filled transformer line ball coil apparatus easily simple in structure, suitable.
In order to achieve the above object, a kind of oil-filled transformer line ball coil apparatus of the present utility model.Be achieved through the following technical solutions: a kind of oil-filled transformer line ball coil apparatus, comprise and press nail-plate, pressure oncomelania bolt, pressure washer, wherein, press nail-plate to be horizontally fixed on the transformer core folder, press on the nail-plate and have screwed hole, press the oncomelania bolt to be threaded, press oncomelania bolt lower end to fixedly connected with pressing washer again, press washer to be pressed on the pressing plate of transformer coil with pressing nail-plate.
As preferably, the screwed hole internal thread of opening on the described pressure nail-plate is the M36 screw thread, and press oncomelania bolt external screw thread for and the M36 screw thread of pressing nail-plate screwed hole internal thread to match.
In sum, compared with prior art, the beneficial effects of the utility model are: the utility model is directly being pressed tapping hole on the nail-plate by to pressing the improvement of nail-plate structure, selects the pressure oncomelania bolt of correspondingly-sized specification for use, is threaded with it.Press the oncomelania bolt by precession, make the fixedly connected pressure washer in its lower end compress the transformer coil pressing plate, realize being fixed the device body.The utility model has been simplified the structure of line ball loop mechanism, under the condition that has reduced component processing and installation procedure, has same action effect, has effectively reduced the input of manpower and materials, has saved cost and has reduced workload again.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is that the utility model provides structural representation;
Fig. 2 presses the nail-plate vertical view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Fig. 1 and Fig. 2, a kind of oil-filled transformer line ball coil apparatus, comprise and press nail-plate 1, press oncomelania bolt 2, press washer 3, wherein, press nail-plate 1 to have screwed hole 5, and be horizontally fixed on the transformer core folder 4, press oncomelania bolt 2 to be threaded with pressing nail-plate 1, and pass screwed hole 5, its lower end is fixedly connected with presses washer 3, by precession and the pressure oncomelania bolt 2 of pressing nail-plate to be threaded, the pressure washer 3 of its lower end compresses the transformer coil pressing plate 6 that joins gradually, compress coil by pressing plate 6, owing to press nail-plate to be horizontally fixed on the folder 4 of transformer core, folder 4 clamps iron core, vertically compress coil by pressing plate 6 again, transformer body is compressed, and as preferably, coping screwed hole internal thread is the M36 screw thread, the external screw thread of the pressure oncomelania bolt 2 that is threaded mutually with it selects the M36 screw thread, select this model bolt for use, draw materials extensively, applied widely.
The utility model, the making and the welding sequence of pressing the oncomelania mother on the basis of former live conductor loop mechanism, have been reduced, directly screwed hole is attacked and pressing on the nail-plate 1, by pressing oncomelania bolt 2 directly to be threaded with coping, the oncomelania bolt is pressed in precession, the pressure washer 3 that makes its lower end clamping platen 6 gradually when oncomelania bolt 2 is pressed in precession is fixed coil, cooperates the iron core folder to be fixed transformer body.A general transformer will adopt the utility model with 28 pressure oncomelania bolts, can reduce the making and the welding of 28 self-clinching nuts, has saved material greatly and has reduced working strength simultaneously, has reduced workload, has applicability preferably.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
