Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The invention discloses an insulating pad for a dry-type transformer, such as figure 1 , 2 As shown in and 3, the insulating spacer provided by the present invention includes a spacer body 1 and a pressing structure, the pressing structure is arranged above the spacer body 1, and is movably connected with the spacer body 1, and the pressing structure The structure is used to compress the spacer body 1 and is constrained by the spacer body 1. The spacer body 1 is used to limit the distance between the high-voltage coil 5, the low-voltage coil 3 and the insulating cylinder 4, preventing the transformer from being damaged during transportation or under severe conditions. Due to vibration...

Abstract

The invention provides an insulation pad for the dry-type transformer. The insulation pad comprises a pad block body and a down-pushing structure, the down-pushing structure is arranged above the pad block body and is flexibly connected with the pad block body, the pad block body is connected with a transformer body, the pad block body comprises a first fixing structure, a second fixing structure and a third fixing structure, the first fixing structure is arranged above a low voltage coil, the second fixing structure is arranged above an insulation cylinder, the third fixing structure is arranged above a high-tension coil, and the second fixing structure is flexibly connected with the first fixing structure and the third fixing structure. Pad blocks are respectively arranged for high-tension coils, low-tension coils and insulation cylinders, the spacing between the transformers in the transportation process or under harsh environments is further ensured, and the down-pushing structure is connected with the pad block body, clamping grooves are not needed in the pad block body, and costs are further saved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an insulating cushion block for a dry-type transformer. Background technique [0002] In the manufacturing process of large-scale transformers, the axial compression of the transformer is very critical to resist the short-circuit axial electromagnetic mechanical force. The traditional compression method is usually used to position the top nut, and then use a rectangular insulating block to support the coil, but it is reliable. In addition, different transformer manufacturers have different axial compression methods. For transformers with different capacities, the types of insulating pads will also vary. There are different. [0003] For example, the Chinese patent application number: 201520689345.2 discloses an insulating block for dry-type transformers, including an insulating block body integrally formed with insulating materials, the top of the insulating block body is p...
