Description
[technical field]
The utility model relates to high-tension transformer, relates in particular to a kind of multiple-grooved high-tension transformer skeleton and multiple-grooved high-tension transformer.
[background technology]
For the very high transformer of voltage,, be difficult to solve its Insulation Problems if winding sandwich wound in a mounting groove can cause the relative voltage of adjacent two layers very high.Therefore, as far as general high-tension transformer, in order to reduce the voltage stress of high pressure winding, the high pressure winding is divided into a plurality of windings in series forms, each winding lays respectively in the different insulation tanks.Between adjacent series connection winding, there is the insulation barricade to intercept, the Insulation Problems between having solved mutually.
Fig. 1 shows the structure and the winding cabling sketch map of traditional high-tension transformer skeleton 3.In the high-pressure side of transformer, the high pressure winding has been divided into the winding 1 and 2 of two series connection, and the voltage on each winding is reduced to 1/2nd of original single winding voltage.In Fig. 1,101 is the end of incoming cables of high pressure winding 1, begin from the bottom of skeleton 3 high-pressure troughs around.102 is the superiors' winding of high pressure winding 1, is connected to the bottommost of high pressure winding 2 through connecting line.202 is the superiors' winding of high pressure winding 2.Like this, born the half the of whole transformer ceiling voltage between 102 and 202.In most positions of high pressure winding,, can bear this high voltage fully between two windings owing to there is insulation barricade 3 to isolate.
But; The top winding of high pressure winding 1 will be connected with the bottom winding of high pressure winding 2; Generally be on the insulation barricade 301 between two windings, vertically to leave a wire casing 302, can the top winding of high pressure winding 1 and the bottom winding of high pressure winding 2 be coupled together through wire casing 302.But, having the place of wire casing 302 at the insulation barricade, the insulation between two windings has just been weakened.This address this problem, a kind of way is the thickness that increases the insulation barricade, strengthens distance between two windings to improve the insulation property at groove position, the shortcoming of this way is to have strengthened the thickness of the barricade that insulate; Another kind of way is on electromagnetic wire, to put the Teflon sleeve pipe to guarantee that electromagnetic wire can not puncture because of voltage stress.The shortcoming of sleeve pipe is conspicuous especially; Because the line end at each high pressure winding will put the Teflon sleeve pipe, be unfavorable for the automated job of coil winding machine, secondly be because the Teflon sleeve pipe has taken the window that partly winds the line; Thereby cause whole winding to cause clamp easily around must be smooth.
