The method provides a reasonable energy-saving transformation scheme for increasing the capacity of an S10 transformer by reasonably utilizing original materials and adding some new materials according to the performance and the structure of an original transformer based on the obsolete S7 transformer in the distribution network. According to the transformation method, the capacity and the performance level of the S7 transformer are greatly improved, the effective materials of the transformer are fully utilized, and the national energy-saving and emission-reducing requirements are met.
Description
Technical field
The present invention relates to a kind of remodeling method of transformer, relate in particular to a kind of for power distribution network S7 type transformer the energy-conserving reconstruction method to the increase-volume of S10 type transformer.
Background technology
Along with economic development, people's living standard improves constantly, power consumption also constantly increases thereupon, original S7 type transformer is overload operation, need the S10 type transformer that the replacing capacity is larger, eliminate thus large quantities of S7 type transformers, and eliminate the S7 type transformer got off, can only treat as waste disposal, caused the great wasting of resources.
Therefore, how to realize that S7 type transformer is devoted to one of problem solved to a kind of those skilled in the art of being of reducing energy consumption of S10 type transformer increase-volume.
Summary of the invention
The object of the invention is to overcome the defect of prior art and a kind of energy-conserving reconstruction method for the increase-volume of power distribution network S7 type transformer is provided, the method makes S7 type transformer capacity and performance rate have significantly lifting, the effective material of transformer to be fully used.
The object of the present invention is achieved like this:
A kind of energy-conserving reconstruction method for the increase-volume of power distribution network S7 type transformer of the present invention comprises the following steps:
Transformation unshakable in one's determination: after silicon steel sheet is removed, with saw foam bits, pile up silicon steel sheet is stacked, surperficial transformer oil is blotted, then with soft cloth, the silicon steel sheet surface is cleaned, become 3 grades of stacks by 2 grades of original stack modes, and use former folder clamping;
The transformation of winding technique: press the Long Circle structure and again winding technique is shaped;
The transformation of transformer body and lead-in wire assembling: according to the structure of Long Circle winding, set up upper and lower core insulation, and in axial compression place reinforcement compression dynamics, after the high and low pressure lead-in wire is prepared again by the requirement of S10 type transformer technology, transformer body integral body enters the stove drying, presses S10 type transformer technological requirement drying time and carries out;
The transformation of oil tank of transformer: oil tank of transformer transform Full-sealing corrugated oil box as, the ripple wing stretches with the breathing of transformer oil volume, make the oil of ambient atmosphere and transformer inside isolated, prevent and slow down the deteriorated and humidified insulation of oil reservoir, corrugated plate is extruded by mould with the 1.2mm thin plate;
The oiling of transformer: transformer adopting vacuum oil mode oiling.
The inventive method be take superseded S7 type transformer in power distribution network and, as basis, according to original transformer performance and structure situation, is rationally utilized original material and add the part new material, makes reasonably the reducing energy consumption scheme to S10 type transformer increase-volume increase-volume.
Remodeling method of the present invention makes the capacity of S7 type transformer and performance rate have significantly lifting, the effective material of transformer to be fully used, and meets the requirement that national energy-saving reduces discharging.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
The present invention, for the energy-conserving reconstruction method of power distribution network S7 type transformer increase-volume, comprises the following steps:
Transformation unshakable in one's determination: after silicon steel sheet is removed, with the saw foam, consider to be worth doing and pile up silicon steel sheet is stacked, surperficial transformer oil is blotted, with soft cloth, the silicon steel sheet surface is cleaned again, press S10 type transformer technological requirement closed assembly again, by 2 grades of original stack modes, become 3 grades of stacks, and use former folder to clamp;
The transformation of winding technique: press the Long Circle structure and again winding technique is shaped;
The transformation of transformer body and lead-in wire assembling: in view of the useful life of S7 type TRANSFORMER INSULATING MATERIAL, all processing again of insulating part of transformer after transformation, and for the Long Circle winding construction, rationally make upper and lower core insulation, and suitably strengthen by S10 type transformer body assembly technology at the axial compression place, after the high and low pressure lead-in wire is prepared again by the requirement of S10 type transformer technology, transformer body integral body enters the stove drying, strictly presses S10 type transformer technological requirement drying time and carries out;
The transformation of oil tank of transformer: oil tank of transformer transform Full-sealing corrugated oil box as, the ripple wing stretches with the breathing of transformer oil volume, make the oil of ambient atmosphere and transformer inside isolated, prevent and slow down the deteriorated and humidified insulation of oil reservoir, corrugated plate is extruded by mould with the 1.2mm thin plate;
The oiling of transformer: transformer adopting vacuum oil mode oiling.
After tested, after transformation, transformer performance meets the national standard of S10-M-400/10 transformer fully, and performance comparison is as following table:
From above table, after transformation, transformer capacity has increased by 60%, and unit capacity is unloaded, load loss has reduced respectively 35%, 32%, and after transformation, the transformer performance index, all higher than national standard, meets the performance requirement of S10 type distribution transformer.
Before and after transformation, the weight table of comparisons is as follows:
Whole transformation process main material cost statistics is as follows:
(1) the copper cash expense is 19700 yuan, removes 8600 yuan of original copper cash amortization charges, 11100 yuan of actual copper cash Meteorologicals;
(2) silicon steel sheet new film expense is 4700 yuan, because former silicon steel sheet is all utilized, and 4700 yuan of actual Meteorologicals;
(3) the transformer oil Meteorological is 0 yuan;
(4) fuel tank folder expense is 2100 yuan, removes 800 yuan of former transformer steel ironware amortization charges, 1300 yuan of actual Meteorologicals;
(5) 10000 yuan/platform of S7-250 transformer cost.
27100 yuan/platform of main material input cost, the expenses such as component insulation are calculated by 2000 yuan/platform, and after the transformation, the S10-M-400/10 material cost is 29100 yuan/platform (expense that does not contain labor management) according to a preliminary estimate.New processing S10-M-400/10 material cost is 30450 yuan/platform.Save 1350 yuan/platform.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
