Description
Technical field
The present invention relates to a kind of high-tension transformer, a kind of high-tension transformer installing iron core high pressure baffle plate, belongs to transformer technology field specifically.
Background technology
In prior art, high-tension transformer often occurs, between high pressure winding and transformer core, high voltage arc problem occurs, and destroys transformer insulated, finally can cause transformer damage.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of high-tension transformer installing iron core high pressure baffle plate, can effectively avoid, between high pressure winding and transformer core, high voltage arc problem occurs, process easy, cost is low.
According to technical scheme provided by the invention, the high-tension transformer installing iron core high pressure baffle plate comprises iron core body, one of them iron core column of iron core body is as stiff end, be fixed on mounting base by steel band pull bar fixture, it is characterized in that: the outer face of another iron core column of iron core body is as installation end, install transformer wire bag, the inner face of another iron core column of iron core body is held as protection, secured core high pressure baffle plate; Described transformer wire handbag draws together end cylinder, low pressure winding and high pressure winding, and end jacket casing is contained in iron core column, the low pressure winding of the step that low centre, coiling two ends is high on end cylinder, coiling high pressure winding in the middle part of low pressure winding; Low pressure winding outermost step is low-pressure end, and last step of high pressure winding is high-pressure side.
Further, iron core body is wide window CD shaped iron core.
Further, iron core high pressure baffle plate comprises the lower baffle plate be fixed on the inner face of iron core column, and lower baffle plate both sides are provided with the card article of protrusion, and two side shields are installed on the card article of lower baffle plate both sides respectively by the draw-in groove of end.
Further, iron core high pressure baffle plate adopts poly (methyl methacrylate) plate material to make.
Compared with the prior art the present invention has the following advantages:
(1) high pressure winding adopts ledge structure coiling, the voltage of high pressure winding increases progressively from inside to outside, maximum potential is positioned at the most external in the middle of high pressure winding, make maximum potential be positioned at the centre of core window, avoid due to maximum potential and left and right iron core column distance inequality and cause high pressure winding and iron core column nearer end to strike sparks;
(2) adopt iron core high pressure baffle plate, can effectively prevent from, between high pressure winding and iron core, high voltage arc phenomenon occurs, protection transformer, the distance between high pressure winding and iron core can be reduced, thus reduce core window height and width, finally reduce volume of transformer, reduce costs;
(3) iron core high pressure baffle plate adopts high pressure poly (methyl methacrylate) plate to process, and withstand voltage height is easy to process, and better appearance;
(4) iron core high pressure baffle plate adopts splicing construction, can avoid producing the gap that high voltage arc occurs, and splices easy, close and firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is side shield structural representation.
Fig. 3 is lower baffle plate structural representation.
Description of reference numerals: cylinder, 4-low pressure winding, 5-high pressure winding, 6-side shield, 6.1-draw-in groove, 7-lower baffle plate, 7.1-card article, 8-steel band pull bar fixture at the bottom of 1-iron core body, 2-mounting base, 3-.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 3, the present invention mainly comprises iron core body 1, and iron core body 1 is wide window CD shaped iron core.One of them iron core column of iron core body 1, as stiff end, is fixed on mounting base 2 by steel band pull bar fixture 8.Transformer wire bag, as installation end, is installed in the outer face of another iron core column of iron core body 1, and the inner face of another iron core column of iron core body 1 is held as protection, secured core high pressure baffle plate.
Described iron core high pressure baffle plate comprises the lower baffle plate 7 be fixed on the inner face of iron core column, and card article 7.1, two side shields 6 that lower baffle plate 7 both sides are provided with protrusion are installed on the card article 7.1 of lower baffle plate 7 both sides respectively by the draw-in groove 6.1 of end.Iron core high pressure baffle plate adopts poly (methyl methacrylate) plate material to make; can effectively prevent from, between high pressure winding and iron core, high voltage arc phenomenon occurs; protection transformer; the distance between high pressure winding and iron core can be reduced; thus reduce core window height and width; final reduction volume of transformer, reduces costs.
Described transformer wire handbag draws together end cylinder 3, low pressure winding 4 and high pressure winding 5, and end cylinder 3 is sleeved in iron core column, the low pressure winding 4 of the step that low centre, coiling two ends is high on end cylinder 3, coiling high pressure winding 5 in the middle part of low pressure winding 4.Low pressure winding 4 outermost step is low-pressure end, and last step of high pressure winding 5 is high-pressure side.The voltage of high pressure winding increases progressively from inside to outside, and maximum potential is positioned at the most external in the middle of high pressure winding, makes maximum potential be positioned at the centre of core window, avoids due to maximum potential and left and right iron core column distance inequality and causes high pressure winding and iron core column nearer end to strike sparks.
The present invention can effectively avoid, between high pressure winding and transformer core, high voltage arc problem occurs, and process easy, cost is low.
