Abstract
The utility model relates to the technical field of transformers, in particular to a transformer clamp magnetic shielding structure. The transformer clamp magnetic shielding structure comprises a shielding board and is characterized in that the shielding board is rectangular and is fixed on a clamp through bakelite bolts and bakelite nuts, and a shielding protecting pipe fixed on the clamp wraps the periphery of the shielding board. The transformer clamp magnetic shielding structure is simple in structure, convenient to use, reasonable in design, and flexible in application, can effectively reduce partial discharge of transformers and lower load loss, and is mainly applied to 66kV power transformers and power transformers with higher voltage classes.
Description
(1) technical field
The utility model relates to the transformer technology field, particularly a kind of transformer folder magnet shielding structure.
(2) background technology
In the transformer running, except the main flux that in iron core, circulates, outside iron core, also be accompanied by the existence of leakage flux all the time.Particularly jumbo transformer because the support plate on the folder is bigger at the area in this leakage field district, can produce a large amount of eddy current loss, even some position produced serious local overheating, influences the life-span of minor insulation spare, accelerates transformer insulated aging.The life loss that the life loss that the local overheating that high-power transformer produces owing to leakage field causes causes than ageing of insulation is also serious many, in the course of time with the safe operation of crisis transformer.
(3) summary of the invention
The utility model provides a kind of transformer folder magnet shielding structure simple in structure, easy to use in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of transformer folder magnet shielding structure comprises barricade, and it is characterized in that: described barricade is rectangle, and is fixed on the folder by bakelite bolt and bakelite nut, and barricade is peripheral to be surrounded with the shielding pillar that is fixed on the folder.
The utility model is bolted to barricade on the folder with bakelite, and the outside surrounds with the shielding pillar, avoids the wedge angle burr, and the shielding pillar is fixed on the folder, guarantees well contact; Barricade can make folder play magnetic screening action, and the shielding pillar can make folder play electric screening action.
More excellent scheme of the present utility model is:
Described barricade and shielding pillar all by plain cushion, bullet pad and nut and folder locking, keep well contact.
Described barricade be the surface anyhow to the silicon steel sheet of coated papers groove, silicon steel sheet connects ground strip, the ground strip skin is enclosed with two-layer crimped paper and one deck strap.
Described shielding pillar is the copper rod of the smooth in appearance of connection ground strip, and the copper rod surface is enclosed with aluminium foil, metal wrinkled paper and crimped paper from inside to outside successively.
The utility model is simple in structure, and is easy to use, reasonable in design, and applying flexible can effectively reduce transformer partial discharge, reduces load loss, is mainly used in the power transformer of 66KV and above electric pressure.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is left TV structure schematic diagram of the present utility model;
Fig. 3 is plan structure schematic diagram of the present utility model.
Among the figure, 1 barricade, 2 shielding pillars, 3 bakelite bolts, 4 bakelite nuts, 5 plain cushions, 6 bullet pads, 7 nuts.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises barricade 1, and described barricade 1 is rectangle, and is fixed on the folder by bakelite bolt 3 and bakelite nut 4, and barricade 1 is peripheral with shielding pillar 2 encirclements that are fixed on the folder; Described barricade 1 and shielding pillar 2 are all by plain cushion 5, bullet pad 6 and nut 7 and folder locking; Described barricade 1 be the surface anyhow to the silicon steel sheet of coated papers groove, silicon steel sheet connects ground strip, the ground strip skin is enclosed with two-layer crimped paper and one deck strap; Described shielding pillar 2 is the copper rod of the smooth in appearance of connection ground strip, and the copper rod surface is enclosed with aluminium foil, metal wrinkled paper and crimped paper from inside to outside successively.
(1) connection of each parts
Barricade 1 usefulness bakelite bolt 3 is fixed on the folder limb plate, and around being enclosed in shielding pillar 2, barricade 1 and shielding pillar 2 are fixed with folder limb plate respectively, keep good earth, at last with plain cushion 5, bullet pad 6 and nut 7 lockings.
(2) barricade assembling
Ground strip and silicon steel sheet weld together, and the ground strip outside is partly repeatedly two-layer with crimped paper, and outsourcing strap half is one deck repeatedly, and after with the paper groove silicon steel sheet long axis direction being wrapped up, the outside wraps up at short-axis direction with the paper groove again.
(3) shielding pillar
Copper rod and ground strip weld together, and metal wrinkled paper half-stack package one deck is used then with aluminium foil half-stack package one deck in the copper rod outside, uses wrinkle paper bag capacity at last.
This device can effectively reduce transformer partial discharge, reduces load loss.This design is mainly used in the power transformer of 66kV and above electric pressure.
Claims (4)
