Abstract
The utility model discloses an insulating oil channel cushion block for a 110kV transformer, which comprises a low-voltage coil, a medium-voltage coil and a high-voltage coil which are mounted in a sleeving manner from inside to outside, wherein the low-voltage coil, the medium-voltage coil and the high-voltage coil are uniformly provided with the insulating oil channel cushion blocks in width directions. According to the insulating oil channel cushion block, the low-voltage coil, the medium-voltage coil, the high-voltage coil and insulating oil channel cushion block structures are mounted together in a sleeving manner, so that the standardization is implemented; insulating paper board strips with standard widths can be purchased directly, so that a processing procedure is simplified; a piercing mold has only one specification; equipment is simplified; and the management is simplified.
Description
Technical field
The utility model belongs to transformer insulated field, relates to a kind of insulation oil duct cushion block, especially a kind of 110kV transformer insulation oil duct cushion block.
Background technology
The 110kV transformer generally has Shuan Quan and two kinds of patterns of three circles, generally speaking according to the core-diameter size, high (in) the stay cushion block shelves of low-voltage coil count unanimity.Because high (in) the internal diameter difference of low-voltage coil, just need the insulation oil duct cushion block of different in width; Three coil transformers are example: the low pressure wide oil duct cushion block of 30mm, the middle pressure wide oil duct cushion block of 40mm, the high pressure wide oil duct cushion block of 50mm.The oil duct cushion block is made and will be equipped with three kinds of width specifications band material, and blank size is many, and the oil duct cushion block dash that lack will be with three kinds of moulds, so complicated operation, the cushion block kind is many, mould is many, management is difficult.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of 110kV transformer insulation oil duct cushion block is provided, this cushion block is united the insulation oil duct cushion block of senior middle school's low-voltage coil, carry out standardization, and can directly purchase the insulating board billot of normal width, realize the procedure simplification.The piercing die tool is also only used a kind of specification, and equipment is also oversimplified, and realizes the management simplification.
Comprise the low-voltage coil, intermediate voltage winding and the high-tension coil that are sleeved on from inside to outside together; Described low-voltage coil, intermediate voltage winding and high-tension coil along the width of cloth to evenly being provided with insulation oil duct cushion block.
Above-mentioned insulation oil duct cushion block docks the back and is in the same place with coil stationary with the stay notch.
The width specifications of above-mentioned insulation oil duct cushion block is 40mm.
The purpose of this utility model solves by the following technical programs:
The utility model is carried out standardization by basic, normal, high three kinds of coils and insulation oil duct cushion block structure suit are set together, and can directly purchase the insulating board billot of normal width, has realized the procedure simplification.The piercing die tool is also only used a kind of specification, and equipment is also oversimplified, and realizes the management simplification.
Description of drawings
Fig. 1 is vertical view of the present utility model.
Wherein: 1 is low-voltage coil; 2 is intermediate voltage winding; 3 is high-tension coil; 4 are insulation oil duct cushion block.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1～2, this 110kV transformer comprises the low-voltage coil 1, intermediate voltage winding 2 and the high-tension coil 3 that are sleeved on from inside to outside together with insulation oil duct cushion block; Circumferentially evenly be provided with insulation oil duct cushion block 4 on described low-voltage coil 1, intermediate voltage winding 2 and the high-tension coil 3.Insulation oil duct cushion block 4 docks the back and is in the same place with coil stationary with the stay notch.The width specifications of insulation oil duct cushion block 4 is 40mm.
Transformer industry is all being advocated standardized designs.The utility model technology is exactly that the insulation oil duct cushion block of senior middle school's low-voltage coil is united, and carries out standardization, and can directly purchase the insulating board billot of normal width, realizes the procedure simplification.The piercing die tool is also only used a kind of specification, and equipment is also oversimplified, and realizes the management simplification.
Another kind of situation:
Bigger as core-diameter, the internal diameter of high-tension coil is corresponding also bigger, the stay cushion block span of high-tension coil occurs when big, uses a kind of cross-over block (wide as 40mm) of specification too.Only the quantity of the stay cushion block of high-tension coil will increase, and incremental change is 4 multiple.
Claims (3)
1. a 110kV transformer is characterized in that: comprise the low-voltage coil (1), intermediate voltage winding (2) and the high-tension coil (3) that are sleeved on from inside to outside together with insulation oil duct cushion block; Described low-voltage coil (1), intermediate voltage winding (2) and high-tension coil (3) along the width of cloth to evenly be provided with the insulation oil duct cushion block (4).
2. 110kV transformer according to claim 1 is characterized in that: be in the same place with coil stationary after described insulation oil duct cushion block (4) docks with the stay notch with insulation oil duct cushion block.
3. 110kV transformer according to claim 1 is with insulation oil duct cushion block, and it is characterized in that: the width specifications of described insulation oil duct cushion block (4) is 40mm.
