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
The present invention relates to a kind of first stay assembly technology of 180,000/240,000 transformer high-voltage of carrying that have, belong to transformer technology field.
Background technology
There are the first hair oil gaps of year 180,000/240,000 transformer high-voltages to be designed to install stay, in practical operation, stay installs in a whole set of operation, whole-set coil enter stove dry after, due to dry, shrinking, there is gap in first moulding square ring of stay and high pressure, causes stay loosening, even come off, lost the effect of support and oil clearance.If use and support stay at the first head of high pressure place, need connect with a large amount of PVA are gluing, easily there is partial discharge.Once there is loose or dislocation phenomenon in stay, need cover weldering to recover, cause personnel and waste of time.
Summary of the invention
The object of the invention provides a kind of first stay assembly technology of 180,000/240,000 transformer high-voltage of carrying that have, and prevents that the first head of high pressure place stay from coming off, and guarantees that oil clearance is unimpeded, has guaranteed product quality, increases work efficiency, and solves the problems referred to above that exist in background technology.
Technical scheme of the present invention is: have first the stay assembly technology of 180,000/240,000 transformer high-voltage of carrying, step is as follows: 1. use corrugated board to replace stay, corrugated board is wrapped having on the first head of 180,000/240,000 transformer high-voltages of carrying of bandaging, between every layer of corrugated board, with the cardboard of 0.5 millimeters thick, separate, until with have that to carry the forming angle central shoring of the first head of 180,000/240,000 transformer high-voltages tight, play a supportive role; 2. the corrugation gap between corrugated board, as oil clearance, becomes oil circuit, guarantees that oil circuit is unimpeded.
Good effect of the present invention: prevent that the first head place of high pressure stay from coming off, guarantee that oil clearance is unimpeded, solved the product drying phenomenon that backstay comes off of coming out of the stove, guarantee and improved product quality; Avoided using PVA glue at Shou Touchu, be difficult for causing first head place partial discharge, improved product assembly quality, enhanced productivity.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention schematic diagram;
In figure: corrugated board 1, have and carry first 2 of 180,000/240,000 transformer high-voltage, moulding square ring 3.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the invention will be further described
There is first the stay assembly technology of 180,000/240,000 transformer high-voltage of carrying, step is as follows: 1. use corrugated board 1 to replace stay, corrugated board is wrapped on having of bandaging carried first 2 of 180,000/240,000 transformer high-voltage, between every layer of corrugated board, with the cardboard of 0.5 millimeters thick, separate, until with have moulding square ring 3 stretchings that carry the first head of 180,000/240,000 transformer high-voltages, play a supportive role; 2. the corrugation gap between corrugated board, as oil clearance, becomes oil circuit, guarantees that oil circuit is unimpeded.
Claims (1)
1. one kind has first the stay assembly technology of 180,000/240,000 transformer high-voltage of carrying, it is characterized in that step is as follows: 1. use corrugated board (1) to replace stay, corrugated board is wrapped having on the first heads of 180,000/240,000 transformer high-voltages of carrying (2) of bandaging, between every layer of corrugated board, with the cardboard of 0.5 millimeters thick, separate, until with have moulding square ring (3) stretching that carries the first head of 180,000/240,000 transformer high-voltages, play a supportive role; 2. the corrugation gap between corrugated board, as oil clearance, becomes oil circuit, guarantees that oil circuit is unimpeded.
