Abstract
The invention provides a magnetic shunt compaction device of a tightening belt structure. The magnetic shunt compaction device of the tightening belt structure comprises a pull ring nut, a tightening belt and a pressing block, wherein a freely rotating round ring is arranged on the nut and a manual tightening device is arranged on the tightening belt. By arranging a compaction area between a clamping piece and the tightening belt, the tightening belt provides a tightening force to control a gap between a magnetic shunt and a magnetic core main pole.
Description
Technical field
The invention provides a kind of device that reduces the transformer leakage field, particularly relate to a kind of magnetic shunt hold down gag of belt tensioner structure.
Background technology
Along with the development of China's electric utility, large capacity, high-tension large-scale power transformer have become the direction of transformer industry development.Power transformer causes a large amount of electric energy losses in the electric power course of conveying, and leakage field is as the key factor that affects transformer loss, its size is also more and more important to the performance impact of transformer, can effectively reduce leakage field and install magnetic shunt additional in suitable position, coil two ends.
Magnetic shunt is installed between core clamping and the coil, because this superhuge transformer wire loop diameter generally can reach 2 to 3 meters, radius is greater than 1 meter, generally take with the briquetting pad on magnetic shunt when therefore magnetic shunt is installed at present, with wooden mallet slowly drive in this method at diverse location.The defective of the method is magnetic shunt unbalance stress when installing, and the gap is wayward, if the lower and undue force of efficient causes the damage of magnetic shunt easily simultaneously.
The present invention is when adopting a kind of magnetic shunt hold down gag of belt tensioner structure, magnetic shunt when mounted can to tightening force control and stressed evenly, make magnetic shunt when mounted more handy and safe also improved efficient workman's the labour intensity of having saved time decreased simultaneously.
Summary of the invention
The magnetic shunt hold down gag that the purpose of this invention is to provide a kind of belt tensioner structure, it can control the gap size between magnetic shunt and the main pole unshakable in one's determination effectively when magnetic shunt is installed.
To achieve these goals, the present invention adopts following technical scheme:
A kind of magnetic shunt hold down gag of belt tensioner structure is arranged between core clamping and the coil, it is characterized in that: comprise the draw ring nut, belt tensioner and briquetting; Described briquetting is arranged between belt tensioner and the magnetic shunt and with magnetic shunt and is fixedly connected with, and an end of described draw ring nut is connected with belt tensioner, and the other end is connected with core clamping, and during tension, the operation belt tensioner is to compress magnetic shunt.
Described draw ring nut comprises nut and is connected and annulus free to rotate with nut that described belt tensioner is connected with the annulus of draw ring nut.
Described draw ring nut is connected with core clamping by bolt.
The bolt of described connection draw ring nut and core clamping is provided with the inclination angle, guarantees that puller strap is positioned at the center of magnetic shunt.
Described briquetting is positioned at the center of arc of magnetic shunt.
Described briquetting is provided with the cambered surface of just mating with the cambered surface of magnetic shunt.
Described briquetting is provided with baffle plate, belt tensioner landing from the briquetting when preventing from straining.
Described belt tensioner is provided with manual take-up device so that tightening force to be provided.
Compared with prior art, the magnetic screen hold down gag of a kind of belt tensioner structure of the present invention forms the plastic zone by belt tensioner and folder, can effectively compress magnetic screen in installation process.

Embodiment
See also Fig. 1 to shown in Figure 3, the magnetic shunt hold down gag of a kind of belt tensioner structure of the present invention is arranged between core clamping 1 and the coil, comprises draw ring nut 2, belt tensioner 3, briquetting 4, magnetic shunt 5.Described draw ring nut 2 comprises nut 6, pin 8, Sealing shield ring 9, annulus 7, and the described nut side of being provided with body is used for nut and screws, described annulus is fixed on the nut with pin, described Sealing shield ring is welded on the pin, and described pin, Sealing shield ring and annulus cooperate, and annulus can freely rotate.Described briquetting two ends are fixed with baffle plate 11, prevent belt tensioner landing from the briquetting 4, are provided with handle 12 on the described baffle plate.
It is the bolt of original fixedly arm-tie on the folder that described draw ring nut 2 is connected on the iron core folder 1 what utilize, and described bolt has the inclination angle, can guarantee that the belt tensioner position is at the magnetic shunt center; Annulus 7 on the draw ring nut 2 can freely rotate, and can guarantee belt tensioner distortionless deflection when tightening up; With on the belt tensioner 3 that annulus 7 is connected the Manual tightening instrument is arranged, for hold down gag provides thrust; Briquetting 4 has cambered surface, cooperates with the cambered surface of magnetic shunt end face.
When magnetic shunt compresses, first draw ring nut 2 is connected to the correct position on the folder 1, briquetting 4 is placed between magnetic shunt and the belt tensioner, the briquetting position should be in magnetic shunt center of arc, provide first a pretightning force that briquetting is fixed on the magnetic shunt, regulate briquetting to correct position, utilize the plastic zone that forms between belt tensioner and the folder that magnetic shunt is compressed.Should be slow when belt tensioner tightens up, the tightening force that provides should be tried one's best evenly.
The tighten up district of the present invention by forming between iron core folder and belt tensioner compresses magnetic shunt, can effectively reduce the gap between magnetic shunt and the main pole unshakable in one's determination.
The above only is one embodiment of the present invention, it or not whole or unique execution mode, the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading specification of the present invention is claim of the present invention and contains.
