The invention relates to a radial bracing method and device for a transformer body, in particular to a radial bracing device for a transformer body and belongs to the technical field of transformer equipment. According to the technical scheme, the radial bracing device comprises fixing plates (1), adjusting pads (2), insulating tubes I (3), insulating tubes II (4) and cotton ropes (5), wherein round holes matched with the insulating tubes I (3) are formed in the fixing plates (1); multiple fixing plates (1) arranged in parallel sequentially sleeve the corresponding insulating tubes I (3) fromtop to bottom; the insulating tubes II (4) sleeve the outer sides of the corresponding insulating tubes I (3); the insulating tubes II (4) and the fixing plates (1) are in support connection; notchesare arranged in one side of each fixing plate (1); and multiple layers of adjusting pads (2) are arranged in the corresponding notches and are bundled together through the corresponding cotton ropes(5). According to the radial bracing method and device, complete bracing between transformer coils can be ensured, the anti-short-circuit capacity and the anti-vibration operation capacity of the transformer body are improved and the operation requirements of bad transport conditions of a transformer are met.
Description
technical field [0001] The invention relates to a radial tensioning method and device for a transformer body, in particular to a radial tensioning device for a three-phase transformer body, and belongs to the technical field of transformer equipment. Background technique [0002] The three-phase transformer is mainly composed of an iron core and a coil. The iron core is made of silicon steel sheets coated with insulating materials to form a three-phase iron core column, and the three-phase coil is sleeved on the iron core. In traditional transformers, more consideration is given to the axial compression of the iron core column, and the axial compression effect of the transformer body is good. However, there is no effective supporting device in the radial direction, and the ability to resist short-circuit in the radial direction is relatively weak. At the same time, under harsh transportation conditions, there is also a risk of damage to the body. Contents of the invention...
