For clearly demonstrating the scheme in the present invention, providing preferred embodiment below and being described with reference to the accompanying drawings.
As shown in Fig. 1, it is a preferred embodiment of three dimensional wound core transformer and the reactor clamp that the present invention relates to.
As shown in Fig. 1, be a kind of three dimensional wound core transformer of the present invention and reactor clamp better embodiment, this folder comprises suspension ring 1, upper clamping piece 2, lower clamping piece 4 and three stretching screws 3 and is screwed onto described stretching screw respectively
Three clamp nuts 6 on 3, suspension ring 1 are the upper ends being arranged on described stretching screw 3 by screw.Is connected with the tension of described clamp nut 6 by three described stretching screws 3, the iron core of transformer and reactor and coil windings are fixedly clamped between upper clamping piece 2 and lower clamping piece 4, realize the fixing of unshakable in one's determination and coil and protect.
Upper clamping piece 2 and lower clamping piece 4 are two Y shape structure, are the positive Y shape of employing three " branches " in the embodiment shown in Fig. 1.Make to be formed with the space being beneficial to heat radiation between positive Y shape each " branch ".Lower clamping piece 4 is arranged on base 5.
Upper clamping piece 2 comprises casting die 21 on upper clamping piece, lower clamping piece 4 comprises and casting die on upper clamping piece 21 lower clamping piece piece under pressure 42 in opposite directions, iron core and winding are held from bottom by lower clamping piece piece under pressure 42, on upper clamping piece, casting die 21 is pushed down from top by iron core and winding under stretching screw 3 and clamp nut 6 act on, and makes iron core and coil be clamped on upper clamping piece on casting die 21 and lower clamping piece piece under pressure 42 and upper clamping piece piece under pressure 23 and lower clamping piece between casting die 41.
On upper clamping piece, casting die 21 comprises with the radial pressure arm 211 of positive Y shape distribution and the tangential pressure arm 212 vertical with radial pressure arm 211 being fixed on radial pressure arm outer end 211B, and the radial joint portion, pressure arm 211 center of positive Y shape arranges steel pipe 10 to form the centre bore through upper connecting rod 71.Lower clamping piece piece under pressure 42 comprises with the radial support arm 422 of positive Y shape distribution and the tangential support arm 423 vertical with radial support arm being fixedly mounted on radial support arm outer end 422B, and the radial joint portion, support arm 422 center of positive Y shape is provided with steel pipe 10 equally to form the centre bore through lower connecting rod 72.
Two ends of described tangential pressure arm 212 extend nail pressing installation portion 2121 respectively on same radial; The bearing of trend of described nail pressing installation portion 2121 perpendicular to the described radial pressure arm 211 above it, and respectively to close on and direction away from described radial pressure arm 211 extends.Two ends of described tangential support arm 423 extend locating pin installation portion 4231 respectively on same radial; The bearing of trend of described locating pin installation portion 4231 perpendicular to the described radial support arm 422 below it, and respectively to close on and direction away from described radial support arm 422 extends.Described nail pressing installation portion 2121 is provided with nail pressing installing hole 8, and nail pressing adopts bolt so that regulate crush and thrust, and described locating pin installation portion 4231 is provided with locating pin 9.
Casting die 41 on casting die 21 and lower clamping piece piece under pressure 42 and upper clamping piece piece under pressure 23 and lower clamping piece on upper clamping piece, by nail pressing, locating pin 9 and iron yoke cushion block symmetric clamp in the upper and lower end face of winding.
Because each tangential pressure arm 212 two ends are all pressed on the iron yoke cushion block that same line places on end face by a locating pin 9 on two nail pressings and upper clamping piece piece under pressure 23 in the present embodiment, adopt the clamping that five compress point and can provide very strong and very stable.And no matter be all there is comparatively wide arc gap between tangential support arm 423 or between tangential pressure arm 212, form the air circulation heat dissipation channel of coil upper and lower end face, be conducive to air circulation, equally very large ask gap owing to also having between radial pressure arm 211 and between radial support arm 422, make center between three of transformer coils form effective air circulation heat dissipation channel, be conducive to heat radiation.Have again structure simple, material usage lacks and lightweight feature simultaneously.
