Embodiment Construction

[0013] Such as figure 1 As shown, the angled three-dimensional triangular iron core clip of the present invention includes an upper clip 1 and a lower clip 2 . The upper and lower clamps are all processed by channel steel, and then fixedly connected together by triangle irons 3 and 4 to form a frame structure. The upper clamp 1 is provided with a support plate 5 for fixing the lead wires of the high and low voltage coils. There is a round hole in the middle of the triangle iron 3 connected to the upper clip 1, which is used for lifting the whole transformer. The upper clamping part 1 and the lower clamping part 2 are connected by at least four compression screws 6 , at least one compression screw 6 is connected in the middle of the upper clamping part 1 and the lower clamping part 2 . The inside of the upper clamping part 1 and the lower clamping part 2 are oppositely provided with approximately triangular pressing plates 7 whose sides are parallel to the clamping parts. Pr...

Abstract

The invention relates to a clamp, in particular to an angle-folded type clamp for three-dimensional iron cores, and belongs to the technical field of devices for electric power transmission and distribution. The angle-folded type clamp for the three-dimensional iron cores comprises six single V-shaped clamps which are formed by U-steel in a machined mode. An upper clamp is formed by three single clamps and a triangle through screws in a fixedly connected mode, and a lower lamp is formed by another three single clamps and a triangle through screws in a fixedly connected mode. Both the upper clamp and the lower clamp form a frame structure. The upper clamp and the lower clamp are connected through at least four tightly-pressing screws. At least one tight-pressing screw is connected in the middle of the upper clamp and the lower clamp. According to the angle-folded type clamp for the three-dimensional iron cores, a good electromagnetic property of an iron core is prevented from being damaged, capacity of resisting electrodynamic force when sudden short-circuit occurs is improved, and no-load loss and noise are reduced. The angle-folded type clamp for the three-dimensional iron cores is particularly suitable for the three-dimensional iron cores, simple in structure, convenient to use, practical, low in cost, capable of reducing loss and remarkable in effect of reducing noise.

Description

technical field [0001] The invention relates to a clip, in particular to an angled three-dimensional triangular iron core clip, which belongs to the technical field of power transmission and distribution equipment and is suitable for transformers and reactors. Background technique [0002] At present, the three-dimensional wound iron core used in the transformer has a symmetrical three-phase magnetic circuit, small magnetic resistance, and low no-load current. However, if the iron core cannot be effectively protected during the assembly and operation of the transformer, the performance of the iron core will be affected, resulting in no-load loss and increased noise. Traditional iron core clamps cannot provide effective support and protection. Contents of the invention [0003] The purpose of the present invention is to provide an angled three-dimensional triangular iron core clip that can effectively support and protect the three-dimensional triangular iron core and at th...
