Embodiment Construction

[0008] Below in conjunction with accompanying drawing, the present invention will be further described by embodiment

[0009] Assembly process of 180,000 / 240,000 on-load transformer high-voltage header stays, the steps are as follows: ① Use corrugated cardboard 1 to replace the stays, and wrap the corrugated cardboard on the wrapped high-voltage head 2 of on-load 180,000 / 240,000 transformers , each layer of corrugated cardboard is separated by 0.5 mm thick cardboard until it is tightly braced with the forming corner ring 3 of the high-voltage head of the 180,000 / 240,000 transformer to play a supporting role; ②The corrugated gap between corrugated cardboards serves as The oil gap becomes the oil passage to ensure the smooth flow of the oil passage.

Abstract

The invention relates to an on-load 18 KVA (Kilo Volt Amperes) / 24 KVA transformer high pressure head supporting strip assembling technology and belongs to the technical field of transformers. According to the technical scheme, the on-load 18 KVA / 24 KVA transformer high pressure head supporting strip assembling technology comprises utilizing corrugated boards (1) to replace supporting strips, warping the corrugated boards on a bound on-load 18 KVA / 24 KVA transformer high pressure head (2), separating every layer of corrugated board through a 0.5 cm thick paper board until that the corrugated boards and an on-load 18 KVA / 24 KVA transformer high pressure head forming angle ring (1) are tightly adhered to play a role in supporting, enabling corrugated gaps between the corrugated boards to be served as oil gaps, enabling the oil gaps to be oil circuits and guaranteeing smoothness of the oil circuits. The on-load 18 KVA / 24 KVA transformer high pressure head supporting strip assembling technology has the advantages of preventing the supporting strips at the high pressure head from falling off, guaranteeing the smoothness of the oil gaps, solving the falling off problem of the supporting strips after products are dried and discharged from a furnace and guaranteeing and improving the product quality; avoiding utilizing PVA (Poly Vinyl Alcohol) glue at the head, being not easy to cause partially discharging of the head, improving the product assembling quality and improving the production efficiency.

Description

technical field [0001] The invention relates to an assembly process for a high-voltage head stay of a 180,000 / 240,000 transformer with load, and belongs to the technical field of transformers. Background technique [0002] The oil clearance of the high-voltage head of the on-load 180,000 / 240,000 transformer is designed to install stays. In actual operation, the stays are installed in the entire process. There is a gap in the ring, causing the stay to loosen or even fall off, losing the role of support and oil gap. If support stays are used at the high-voltage head, a large amount of PVA glue is required for bonding, which is prone to partial discharge. Once the stays loosen and fall off, they need to be restored by sleeve welding, resulting in a waste of personnel and time. Contents of the invention [0003] The purpose of the present invention is to provide an assembly process for the high-voltage head stays of 180,000 / 240,000 transformers with load, which can prevent t...
