Abstract
Disclosed is a steel stainless drawstring clamp device for power transformer yoke which comprises a tank shaped clamping piece, an insulating washer, a flat washer, a spring washer and a nut. The utility model is characterized in that the upper yoke and the lower yoke of the power transformer are provided separately between an iron button stem, and provided with steel stainless drawstrings to clamp the front and back tank shaped clamping piece from upper and lower side. The utility model has the advantages of good looking, high clamping strength, low idle load wear and tear, low noise and simple manufacturing technique.
Description
One. technical field
The utility model belongs to electrical equipment technical field, particularly relates to the improvement of power transformer iron yoke clamping device.
Two. background technology
Traditional power transformer iron yoke clamping device has two kinds: the one, and the method that the drawstring that the iron yoke is made by semi-drying glass adhesive tape clamps, it is to strain its surface with half-dried glass adhesive tape, there is surface irregularity, shortcoming not attractive in appearance, that chuck strength is relatively poor; The 2nd, adopt the silicon steel sheet punching of iron yoke, utilize bolt to pass the method that every silicon steel clamps, because every silicon steel all will carry out punching, not only there is complex process but also causes the power transformer performance to reduce, the big and big shortcoming of noise of transformer noload losses.At the problem that above-mentioned traditional power transformer iron yoke clamping device exists, study a kind of new power transformer iron yoke drawstring clamping device, be very important to replace traditional transformer iron yoke clamping device.
Three. summary of the invention
The purpose of this utility model is to manufacture and design a kind of power transformer iron yoke stainless steel drawstring clamping device, the shortcoming that traditional power transformer iron yoke clamping device is not attractive in appearance, chuck strength is poor to overcome, complex manufacturing and serviceability reduce.
The purpose of this utility model reaches like this: power transformer iron yoke stainless steel drawstring clamping device, comprise flute profile folder 4, insulating washer 5, plain washer 6, spring washer 7 and nut 8, the utility model is characterized in that: the upper yoke 1 of transformer and lower yoke 1 be respectively between iron core column 1-1 and the iron core column 1-2, between iron core column 1-2 and the iron core column 1-3, is provided with the stainless steel drawstring 2 of the positive and back flute profile folder 4 of upper and lower tension; Be provided with insulating barrier 3 between described stainless steel drawstring 2 and the iron yoke 1; Described stainless steel drawstring can be one or more for 2 every groups.
Take the utility model of above measure, have attractive in appearance, chuck strength good, no-load loss is little, noise is low and production technology is simple.
Below the utility model is described in further detail in conjunction with the accompanying drawings again.
Four. description of drawings
Accompanying drawing 1 is the front view of the utility model (embodiment);
Accompanying drawing 2 is the utility model (embodiment) plan view;
Accompanying drawing 3 is cutaway views that the A-A of the utility model accompanying drawing 1 amplifies.
Five. embodiment
Accompanying drawing 1 is the front view of the utility model (embodiment), and accompanying drawing 2 is vertical views of the utility model (embodiment).Can see that from accompanying drawing 1, accompanying drawing 2 upper yoke 1 of transformer and lower yoke 1 are respectively between iron core column 1-1 and the iron core column 1-2, between iron core column 1-2 and the iron core column 1-3, be provided with the stainless steel drawstring 2 of upper and lower tension front and back flute profile folder 4, the above and below of flute profile folder 4 is welded with perforation plate washer 4-1 respectively.
Accompanying drawing 3 is cutaway views that the A-A of the utility model accompanying drawing 1 amplifies.A-A from attached 3 analyses and observe the cross section and is more clearly visible the concrete structure that iron yoke 1 clamps.Stainless steel drawstring 2 is like this iron yoke 1 to be clamped: the stainless steel drawstring 2 that two ends is had bolt, after striding across the bottom surface of the top of iron yoke 1 and iron yoke 1 respectively, again bolt is passed the perforation plate washer 4-1 of positive and flute profile folder 4 tops, back respectively, from bolt, pack into insulating washer 5, plain washer 6, spring washer 7 and nut 8 then respectively, the back is tightened nut 8 and is got final product the most respectively, and the iron yoke 1 of transformer is forward and backward and upper and lowerly all obtain clamping like this.
The utility model is through the stainless steel drawstring 2 of same perforation plate washer 4-1, is called same group of stainless steel drawstring 2.The stainless steel drawstring of the utility model setting is two for 2 every groups, and on its perforation plate washer 4-1 is two holes, and the stainless steel drawstring also can be one or more for 2 every groups, Kong Weiyi hole or a plurality of hole on its perforation plate washer 4-1.The transformer stainless steel drawstring 2 that capacity is little can adopt one, and the stainless steel drawstring 2 of the big transformer of capacity can adopt many.
Selecting for use of the utility model material decided according to the amount of capacity of transformer, and its material specification capacious of transformer adopts big, and its material specification that the capacity of transformer is little just adopts smaller.The transformer capacity of the utility model embodiment is 1000KVA, and flute profile folder 4 adopts No. 14 channel-section steels, and stainless steel drawstring 2 every strip adoption thickness are that 3 millimeters, width are 30 millimeters stainless band steel material, and stainless steel drawstring 2 bolts at two ends are the round steel of 12 millimeters of Ф.
