Amorphous alloy transformer body structure having short-circuit resistant capability

Abstract

The invention relates to an amorphous alloy transformer body structure with anti-short circuit capability, which is a three-phase four-frame iron core structure, including upper and lower layers of amorphous alloy iron cores and three-phase windings A, B, and C, and also includes windings distributed in A , between phase B windings, between phase B and C windings, and C-type insulating plates outside the A and C phase windings, hard insulating cylinders in the A, B and C three-phase low-voltage windings, and the left and right sides of the body structure The pressing plate and the left and right clamps, the upper and lower pressing plates and the upper and lower clamps on the upper and lower sides of the body structure; the two layers of amorphous alloy cores are separated by the first reinforcing plate and the second reinforcing plate. In the present invention, through the arrangement of upper and lower clips, left and right side clips, hard insulating cylinder, first reinforcing plate, and second reinforcing plate, the winding can withstand sudden short circuit without destructive deformation and reactance exceeding the standard, amorphous alloy The iron core will not be damaged and affected by the deformation and compression of the windings, which reliably improves the short-circuit resistance of the amorphous alloy distribution transformer.

Description

Technical field [0001] The invention relates to a transformer body structure, in particular to an amorphous alloy transformer body structure with short-circuit resistance capability. Background technique [0002] The society has higher and higher requirements for the quality and reliability of power supply. Improving the short-circuit resistance of transformers can guarantee the safety of power supply and equipment. Due to the structure of the amorphous alloy distribution transformer, its winding is rectangular, the amorphous core is brittle and the thickness is small, and the amorphous alloy distribution transformer has always had the shortcomings of insufficient short-circuit resistance. [0003] The key to improving the short-circuit resistance of amorphous alloy distribution transformers is to strengthen the mechanical strength of the rectangular high and low voltage windings, and to reliably clamp and fix the high and low voltage windings through clamps, so that the amorphous ...
