Abstract
Disclosed is a structure used for installing a strip-shaped magnetic screen on a machine body. The strip-shaped magnetic screen is installed on a trapezoid support piece above a pressing plate, and is limited and fixed through a pressing nail, a first pressing nail cushion block and a second pressing nail cushion block, the trapezoid support piece is provided with an oil guide groove, the trapezoid support piece and the pressing nail cushion blocks are made of high-strength laminated wood or laminated paper boards, and the strip-shaped magnetic screen is installed in the groove of the trapezoid support piece to be limited. The structure used for installing the strip-shaped magnetic screen on the machine body resolves the problems in the installation process of the strip-shaped magnetic screen, and has the advantages of being stable and reliable in structure, being simple to machine, bringing convenience to the compaction of the machine body, and the like.
Description
Technical field
The utility model belongs to technical field of transformer manufacturing, is specifically related to a kind of device figure shape magnetic shield mounting structure.
Background technology
In transformer body, the bar shaped magnetic screen being installed is a kind of effective means that reduces stray loss of transformer.According to the difference of transformer device structure and capacity, the size of device figure shape magnetic screen is different, and whether mounting structure rationally directly has influence on its stability and reliability in the transformer running, and the device body that has influence on simultaneously transformer compresses.
The bar shaped magnetic screen generally is arranged in the reeded strutting piece of pressing plate top tool, and installs before the assembling of device body compresses.Usually, the nail pressing of 110kV transformer is rods arranged in horizontal line and is arranged in by folder web side.The device body compresses and adopts nail pressing to be pressed on the arc strutting piece that is positioned at the pressing plate top.Arc strutting piece unbalance stress with the pressing plate loose contact, can cause the perk of arc strutting piece when serious.Have certain vibration when moving due to transformer, the stability of bar shaped magnetic screen will be greatly affected, simultaneously the circular shape processing difficulties.
Summary of the invention
For the deficiency that exists in above-mentioned existing device figure shape magnetic shield mounting structure, technical problem to be solved in the utility model is to provide a kind of stable, reliable device figure shape magnetic shield mounting structure.
The technical scheme that the utility model adopts is:
A kind of device figure shape magnetic shield mounting structure, bar shaped magnetic screen are arranged on the trapezoidal strutting piece of pressing plate top, and be by nail pressing and the first nail pressing cushion block and the second nail pressing cushion block, that the bar shaped magnetic screen is spacing and fixing.
In technique scheme, on described trapezoidal strutting piece, oil guide groove is set.
In technique scheme, described trapezoidal strutting piece and first, second nail pressing cushion block adopt high strength lamination wood or laminated paper board to make.
In technique scheme, described bar shaped magnetic screen is spacing by carrying out in the groove that is arranged on trapezoidal strutting piece.
The utlity model has following characteristics:
1. bar shaped magnetic screen installation and body pressing device are combined closely, and the reasonable Arrangement nail pressing makes it stressed evenly, compresses by nail pressing and guarantees reliability of structure.
2. trapezoidal strutting piece has rational shape, and the bar shaped magnetic screen is had enough Area of bearing, can guarantee that the strip magnetic screen in high-power transformer does not produce distortion; Compress by nail pressing and can guarantee effectively to contact with pressing plate, its oil guide groove structure, improve the heat radiation of bar shaped magnetic screen greatly simultaneously.
3. trapezoidal strutting piece, the first nail pressing cushion block, the second nail pressing cushion block structure are simple, are convenient to processing, and material insulation property is good.
4. be the conventional structure of transformer owing to adopting nail pressing compactor body, bar shaped magnet shielding structure and body pressing device will be installed be combined as a whole, easy to operate, be easy to realize.
Description of drawings
Fig. 1 is the utility model bar shaped magnetic shield mounting structure end view;
Fig. 2 is the utility model bar shaped magnetic shield mounting structure vertical view.
In figure: the 1-pressing plate; The trapezoidal strutting piece of 2-; 3-bar shaped magnetic screen; 4-the first nail pressing cushion block; 5-the second nail pressing cushion block; The 6-nail pressing.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described below:
Fig. 1,2 is the utility model bar shaped magnetic shield mounting structure end view and vertical view, has the trapezoidal strutting piece 2 of insulating part, the first nail pressing cushion block 4, the second nail pressing cushion block 5 and nail pressing 6.Trapezoidal strutting piece 2 is placed on pressing plate 1, and bar shaped magnetic screen 3 is spacing by carrying out in the groove that is arranged on trapezoidal strutting piece 2.The utility model arranges that with nail pressing rods arranged in horizontal line by original technology changes in Fig. 2 half nail pressing into and is arranged in bar shaped magnetic screen top, improves simultaneously the height of nail pressing 6, reserves the installing space of nail pressing cushion block 4 and nail pressing cushion block 5.The first nail pressing cushion block 4 is installed in the bar shaped magnetic screen, and the second nail pressing cushion block 5 is installed on trapezoidal strutting piece 2, nail pressing directly act on the first nail pressing cushion block 4 and and the second nail pressing cushion block 5 on, trapezoidal strutting piece 2 is compressed fixedly bar shaped magnetic screen simultaneously.In device body assembling final stage, compress nail pressing, complete the spacing and fixing of bar shaped magnetic screen, finish the installation process of bar shaped magnetic screen.
Claims (4)
1. device figure shape magnetic shield mounting structure is characterized in that: the bar shaped magnetic screen is arranged on the trapezoidal strutting piece of pressing plate top, and is by nail pressing and the first nail pressing cushion block and the second nail pressing cushion block, that the bar shaped magnetic screen is spacing and fixing.
