Abstract

A kind of oil immersion-type distribution transformer protects along formula case lid, its lid is located on the case mouth of distribution transformer container body, and the steel plate bending that case lid has square notch by corner is shaped, and it has four right angles mutually alignd and protects edge, edge along case lid is evenly provided with multiple fastening bolt, case lid is fastened on distribution transformer container body by fastening bolt, and this structure fuel tank case lid steel plate thickness is 6mm, and steel plate specification is few, the cost of material is low, case lid mechanical strength is high, and evenness is good, and transformer leakage of oil probability is little; Gummy cord for sealing and case to protect the protection on edge along bolt at case lid under, useful life extends, and transformer operating cost reduces.

Description

A kind of oil immersion-type distribution transformer protects along formula case lid
Technical field
The utility model discloses a kind of oil immersion-type distribution transformer fuel tank case lid manufacturing technology, belong to oil-filled transformer technical field, this product technology is mainly used in middle-size and small-size oil immersion-type distribution transformer fuel tank cover structure, is also applicable to small-sized oil-immersed power transformer oil tank cover structure simultaneously.
Background technology
Oil immersion-type distribution transformer fuel tank cover structure, the same industry is designed to flat plate steel plate structure mostly.This structural steel and iron thickness is 6 ~ 12mm, and fuel tank case lid steel plate thickness is all at more than 6mm, and material cost is high, and case lid welding deformation is large, poor flatness, general assembly gummy cord for sealing discontinuity, easy oil leakage; Gummy cord for sealing and case are exposed between case lid and case edge along bolt, and glue rope is easily aging, and bolt easily gets rusty.
Utility model content
For the defect that oil immersion-type distribution transformer fuel tank cover structure exists, the utility model provides a kind of oil immersion-type distribution transformer and protects along formula case lid, and this structure fuel tank case lid steel plate thickness is 6mm, and steel plate specification is few, and the cost of material is low.
For realizing above-mentioned utility model object, the technical solution adopted in the utility model is: a kind of oil immersion-type distribution transformer protects along formula case lid, its lid is located on the case mouth of distribution transformer container body, the steel plate bending that case lid has square notch by corner is shaped, it has four right angles mutually alignd and protects edge, edge along case lid is evenly provided with multiple fastening bolt, case lid is fastened on distribution transformer container body by fastening bolt, gummy cord for sealing and spacing round steel has been installed with between the case edge of case lid and distribution transformer container body, gummy cord for sealing and spacing round steel are separately positioned on the both sides of fastening bolt, spacing round steel is arranged on fastening bolt and protects between edge.
The utility model beneficial effect is: case lid mechanical strength is high, and evenness is good, and transformer leakage of oil probability is little; Gummy cord for sealing and case to protect the protection on edge along bolt at case lid under, useful life extends, and transformer operating cost reduces.
Accompanying drawing explanation
Fig. 1 oil-filled transformer protects along formula case lid expanded view;
Fig. 2 oil-filled transformer protects and is converted into figure along formula case lid;
Fig. 3 oil-filled transformer protects and assembles partial sectional view along formula case lid and fuel tank;
Be labeled as in figure: 1, case lid, 2, protect edge, 3, fastening bolt, 4, distribution transformer container body, 5, gummy cord for sealing, 6, spacing round steel.
Embodiment
A kind of oil immersion-type distribution transformer protects along formula case lid, its lid is located on the case mouth of distribution transformer container body 4, the steel plate bending that case lid 1 has square notch by corner is shaped, it has four right angles mutually alignd and protects along 2, edge along case lid 1 is evenly provided with multiple fastening bolt 3, case lid 1 is fastened on distribution transformer container body by fastening bolt 3, gummy cord for sealing 5 and spacing round steel 6 has been installed with between the case edge of case lid 1 and distribution transformer container body 4, gummy cord for sealing 6 and spacing round steel 6 are separately positioned on the both sides of fastening bolt 3, spacing round steel 6 is arranged on fastening bolt 3 and protects between 2.
Oil immersion-type distribution transformer protects after formula case lid unfolding and cutting, the square small gap that a length of side is 22mm is washed away respectively at steel plate four angles, turning up 25mm tetra-by broken line size after boring protects along right-angle side, and connect welding equipment after case lid smoothing, polish, entirety eliminates rust, sprays paint.The utility model technical matters is simple, and cost is low, practical.
Transformer protects and is 6mm, material Q235A along formula case lid steel plate thickness, protecting along inner edge distance case along 5mm, protecting along turning up 25mm.Case lid manufacturing process: case lid unfolding and cutting, rush breach 22mm, boring, flanging, smoothing, welding equipment is connect, polish deburring, rust cleaning spray paint.
After case lid is completed, before lid is located on distribution transformer container body, distribution transformer container body adds gummy cord for sealing and spacing round steel, to strengthen the adaptation evenness of case lid, and reduction leakage of oil, case lid is covered on distribution transformer container body, by fastening bolt by fastening for the edge of case lid, strengthen useful life and sealing effectiveness.
