The present invention relates to a kind of high-tension transformer, a kind of high-tension transformer that iron core high pressure baffle plate is installed, 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, destroy transformer insulated, finally can cause transformer damage.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of high-tension transformer that iron core high pressure baffle plate is installed is provided, can effectively avoid, between high pressure winding and transformer core, high voltage arc problem occurs, process easyly, cost is low.
According to technical scheme provided by the invention, the high-tension transformer that iron core high pressure baffle plate is installed 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, transformer wire bag is installed, and the inner face of another iron core column of iron core body is as protection end, secured core high pressure baffle plate; Described transformer wire bag comprises end cylinder, low pressure winding and high pressure winding, and end jacket casing is contained in iron core column, and the low pressure winding of the high step in low centre, coiling two ends on end cylinder, at low pressure winding middle part coiling high 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 on the inner face that is fixed on iron core column, and lower baffle plate both sides are provided with the card article of protrusion, and two side shields are installed on respectively on the card article of lower baffle plate both sides 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 striking sparks apart from uneven high pressure winding and the iron core column nearer end of causing due to maximum potential and left and right iron core column;
(2) adopt iron core high pressure baffle plate, can effectively prevent from, between high pressure winding and iron core, high voltage arc phenomenon occurs, protect transformer, can reduce the distance between high pressure winding and iron core, thereby 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 of high voltage arc occurs, and splice easy, close and firm.

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
The present invention is below further described in connection with the embodiment in accompanying drawing:
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 as protection end, secured core high pressure baffle plate.
Described iron core high pressure baffle plate comprises the lower baffle plate 7 on the inner face that is fixed on iron core column, and 7.1, two side shields 6 of card article that lower baffle plate 7 both sides are provided with protrusion are installed on respectively on the card article 7.1 of lower baffle plate 7 both sides 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 occurring between high pressure winding and iron core high voltage arc phenomenon; protection transformer; can reduce the distance between high pressure winding and iron core; thereby reduce core window height and width; the final volume of transformer that reduces, reduces costs.
Described transformer wire bag comprises end cylinder 3, low pressure winding 4 and high pressure winding 5, and end cylinder 3 is sleeved in iron core column, and the low pressure winding 4 of the high step in low centre, coiling two ends on end cylinder 3, at low pressure winding 4 middle part coiling high pressure windings 5.Low pressure winding 4 outermost steps are low-pressure end, and high pressure winding 5 last step are 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 because maximum potential and left and right iron core column are struck sparks apart from uneven high pressure winding and the iron core column nearer end of causing.
The present invention can effectively avoid, between high pressure winding and transformer core, high voltage arc problem occurs, and processes easyly, and cost is low.
