The paper tube oil retaining type transformer and the manufacturing method thereof have the advantages that overall height is low, cost is low, the manufacturing method is simple, detachment is convenient, oil retaining effect is reliable, and the coil can be wound horizontally.
Description
Technical field
The present invention relates to the technical field of transformer, particularly relate to a kind of transformer coil oil duct and adopt paper tube to keep off oily water conservancy diversion pattern transformer and manufacture method thereof.
Background technology
To large-scale power transformer, coil need arrange oily flow path direction in oil baffle guidance coil, reduces coil temperature rise.The control that in coil, oil flows to, conventional method arranges inside and outside oil baffle, is put in the oil duct place between line cake.The oil baffle that this method is placed will take coil height, and the quantity of putting is more, and oil baffle takies highly also more.If coil adopt sleeping around, outer oil baffle is easy to drop when placing, and outer oil baffle is placed and is inconvenient to take out afterwards.In oil baffle plate structure, oil baffle and screen are difficult to fit tightly simultaneously, and gap is comparatively large, and it is not ideal for keeping off oily effect.
Summary of the invention
The object of the invention be to provide a kind of do not take coil height, installation, convenient disassembly, gear oil paper tube reliable for effect keep off oily formula transformer and manufacture method thereof.
The present invention adopts technical scheme below for achieving the above object:
A kind of paper tube keeps off oily formula transformer, it is characterized in that: adopt the shutoff of paper tube realization to oil duct; The diameter of described paper tube is greater than the gap of coil internal oil channel, outer oil duct, can be out of shape, and be placed in above-mentioned gap under extruding; Described internal oil channel is the gap between inner fiber container and line cake, and described outer oil duct is the gap between outer paper screen and line cake; Paper tube is placed between the inside and outside stay of the oily position of the inside and outside gear of coil, is bonded Oil Guide oil duct with inner fiber container and outer paper screen.
Paper tube keeps off a manufacture method for oily formula transformer, it is characterized in that: adopt the shutoff of paper tube realization to oil duct; The diameter of described paper tube is greater than the gap of coil internal oil channel, outer oil duct, can be out of shape, and be placed in above-mentioned gap under extruding; Described internal oil channel is the gap between inner fiber container and line cake, and described outer oil duct is the gap between outer paper screen and line cake; Paper tube is placed between the inside and outside stay of the oily position of the inside and outside gear of coil, is bonded Oil Guide oil duct with inner fiber container and outer paper screen; Manufacture method is: at coil winding to the oily position of interior gear, according to the spacing between inner bracing strip, gear oilpaper pipe in intercepting, be positioned between inner bracing strip, to stick on inner fiber container one week with glue, inner bracing strip coiling is close to by wire, in compressing, gear oilpaper pipe, makes paper tube slightly be out of shape, thoroughly blocks oil duct; After coil winding completes, placement keeps off oilpaper pipe outward, press the spacing between outer stay, intercept outer gear oilpaper pipe, be positioned between outer stay and the oily position of outer gear, one week is sticked on line cake with glue, two ends back cushion block and outer stay spacing, after all outer gear oilpaper pipes place, be adjacent to outer stay and compress the upper outside paper screen of outer gear oilpaper circumference of cannon bone.
The present invention's tool compared with conventional art has the following advantages: transformer whole height is low, and cost is low; And manufacture method is simple, convenient disassembly, gear oil is reliable for effect, coil can adopt sleeping around.
