Amorphous alloy transformer body structure having short-circuit resistant capability

Abstract

The invention relates to an amorphous alloy transformer body structure having short-circuit resistant capability. The amorphous alloy transformer body structure is a three-phase four-frame iron core structure and comprises an upper-layer amorphous alloy iron core, a lower-layer amorphous alloy iron core and three phase windings A, B and C and also comprises C-shaped insulation plates, hard insulation cylinders, a left-side press plate, a right-side press plate, a left clamp, a right clamp, an upper press plate, a lower press plate, an upper clamp and a lower clamp, wherein the C-shaped insulation plates are arranged between the A-phase winding and the B-phase winding, between the B-phase winding and the C-phase winding and between the A-phase winding and the C-phase winding, the left-sidepress plate and the right-side press plate and the left clamp and the right clamp are arranged at a left side and a right side of the body structure, the upper press plate and the lower press plate and the upper clamp and the lower clamp are arranged at an upper side and a lower side of the body structure, and the two layers of amorphous alloy iron cores are partitioned by a first reinforcement plate and a second reinforcement plate. By arranging the upper clamp, the lower clamp, the left-side clamp, the right-side clamp, the hard insulation cylinders, the first reinforcement plate and the second reinforcement plate, the windings can bear abrupt short-circuit, destructive deformation cannot be generated, reactance does not exceed standard, the amorphous alloy iron cores cannot be pressed to be broken and affect performance by the winding deformation, and the short-circuit resistant capability of the amorphous alloy power distribution transformer is reliably improved.

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 ...
