Abstract
The invention relates to an energy-saving transformation method for increasing the capacity of an S7 transformer of a distribution network, which comprises the transformation step of an iron core, a transformer body, a lead assembly and a transformer oil tank and the oil injection step of the transformer. 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 energy-conserving reconstruction method that is used for power distribution network S7 type transformer to the increase-volume of S10 type transformer.
Background technology
Along with constant development of economy; People's living standard improves constantly, and power consumption also constantly increases thereupon, and original S7 type transformer is overload operation; Need the bigger S10 type transformer of replacing capacity; Eliminate large quantities of S7 type transformers thus, can only treat as waste disposal, caused the great wasting of resources and eliminate the S7 type transformer that gets off.
Therefore, how to realize one of problem that S7 type transformer is devoted to solve 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 objective of the invention is to overcome the defective of prior art and a kind of energy-conserving reconstruction method that is used for the increase-volume of power distribution network S7 type transformer is provided, this method has had significantly S7 type transformer capacity and performance rate and promotes, the effective material of transformer is fully used.
The objective of the invention is to realize like this:
A kind of energy-conserving reconstruction method that is used for the increase-volume of power distribution network S7 type transformer of the present invention may further comprise the steps:
Transformation unshakable in one's determination: after silicon steel sheet is removed, pile up silicon steel sheet is range upon range of, surperficial transformer oil is blotted, with soft cloth the silicon steel sheet surface is cleaned again, become 3 grades of stacks by 2 grades of original stack modes, and use former folder clamping with saw foam bits;
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: based on the structure of Long Circle winding; Set up upper and lower core insulation; And strengthen compressing dynamics at the axial compression place; After the high and low pressure lead-in wire was prepared by the requirement of S10 type transformer technology again, transformer body integral body was gone into the stove drying, pressed S10 type transformer technological requirement drying time and carried out;
The transformation of oil tank of transformer: oil tank of transformer transform hermetically sealed corrugated tank as; The ripple wing stretches with the breathing of transformer oil volume; Make the inner oil of ambient atmosphere and transformer isolated, prevent and the deterioration and the insulation that slow down oil reservoir made moist, 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 is the basis with the S7 type transformer of eliminating in the power distribution network, according to original transformer performance and structure situation, rationally utilizes original material and adds the part new material, makes rational reducing energy consumption scheme to S10 type transformer increase-volume increase-volume.
Remodeling method of the present invention has had significantly capacity and the performance rate of S7 type transformer and promotes, the effective material of transformer is fully used, and meets the requirement of national energy-saving and emission-reduction.
Embodiment
Below in conjunction with embodiment the present invention is described further.
The present invention is used for the energy-conserving reconstruction method of power distribution network S7 type transformer increase-volume, may further comprise the steps:
Transformation unshakable in one's determination: after silicon steel sheet is removed, consider to be worth doing with the saw foam and to pile up silicon steel sheet is range upon range of, 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, become 3 grades of stacks, and use former folder to clamp by 2 grades of original stack modes;
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 service life of S7 type TRANSFORMER INSULATING MATERIAL; Transform transformer insulated all processing again in back, and, rationally make core insulation up and down to the Long Circle winding construction; And suitably strengthen by S10 type transformer body assembly technology at the axial compression place; After the high and low pressure lead-in wire was prepared by the requirement of S10 type transformer technology again, transformer body integral body was gone into the stove drying, and drying time, the strict S10 type transformer technological requirement of pressing was carried out;
The transformation of oil tank of transformer: oil tank of transformer transform hermetically sealed corrugated tank as; The ripple wing stretches with the breathing of transformer oil volume; Make the inner oil of ambient atmosphere and transformer isolated, prevent and the deterioration and the insulation that slow down oil reservoir made moist, corrugated plate is extruded by mould with the 1.2mm thin plate;
The oiling of transformer: transformer adopting vacuum oil mode oiling.
After tested, transform the national standard that the back transformer performance satisfies the S10-M-400/10 transformer fully, performance comparison as follows:
Visible by above table, transforming the back transformer capacity has increased by 60%, and unit capacity is unloaded, load loss has reduced by 35%, 32% respectively, transforms back transformer performance index all to be higher than national standard, satisfies the performance requirement of S10 type distribution transformer.
The weight table of comparisons is following before and after transforming:
Whole transformation process main material cost is added up as follows:
(1) the copper cash expense is 19700 yuan, removes 8600 yuan of original copper cash amortization charges, and actual copper cash drops into 11100 yuan of expenses;
(2) silicon steel sheet new film expense is 4700 yuan, because of former silicon steel sheet all is able to utilize 4700 yuan of actual input expenses;
(3) transformer oil drops into 0 yuan of expense;
(4) fuel tank folder expense is 2100 yuan, removes 800 yuan of former transformer steel ironware amortization charges, 1300 yuan of actual input expenses;
(5) 10000 yuan/platform of S7-250 transformer cost.
27100 yuan/platform of main material input cost, expenses such as component insulation are calculated by 2000 yuan/platform, and transforming back S10-M-400/10 material cost according to a preliminary estimate is 29100 yuan/platform (expense that does not contain labor management).New processing S10-M-400/10 material cost is 30450 a yuan/platform.Save 1350 yuan/platform.
Above embodiment only supplies to explain the present invention's usefulness; But not limitation of the present invention; The technical staff in relevant technologies field under the situation that does not break away 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 each claim.
