Description
Technical field
The invention belongs to electrical equipment technical field, be specifically related to a kind of denoising device for the oil immersed type amorphous alloy distribution transformer.
Background technology
At present, along with improving constantly that energy-saving and emission-reduction require, the application of energy-economic transformer is increasing, country and relevant departments are intensive has put into effect a series of encouragement policies, the guiding user uses energy-economic transformer in a large number, and the non-crystaline amorphous metal distribution transformer is because of its exclusive extreme low-altitude load-loss performance, by concerned.Unite in the 6th batch " the energy-efficient distribution transformer promotion and implementation of energy-conserving product civilian-oriented project detailed rules and regulations " that issue in National Development and Reform Committee, Ministry of Industry and Information and the Ministry of Finance, the subsidy that clearly proposes the amorphous alloy distribution transformer of one-level energy consumption is respectively: 30 yuan/kVA (oil immersion-type distribution transformer) and 40 yuan/kVA (dry-type distribution transformer), not only rank first of all Energy Saving for Distribution Transformer subsidies, and be 1.5 times and 1.6 times that equal energy consumption silicon steel transformer is subsidized.Therefore explosive growth will appear in amorphous alloy distribution transformer.
For a long time, the noise height is a key factor of restriction amorphous alloy distribution transformer large scale application, this has influence on the quality of residents'life of transformer periphery on the one hand, loss when also having increased on the other hand the transformer operation, although each amorphous alloy transformer manufacturing enterprise has all carried out strict control to noise from being designed into the processing links, but the magnetic hysteresis expansion and contraction intrinsic due to amorphous alloy strips is higher more than 10% than silicon steel, so amorphous change noise problem bigger than normal is not effectively solved so far.Many times passively to take the physics outer barrier or mode that nitrile rubber is sealed in the build a house mode of blocking and employing is solved.
Publication number is the damping and de-noising method that the patent of invention of CN101901677A discloses a kind of amorphous alloy transformer, complete the pass window operation of bottom iron core by the amorphous transformer traditional processing technology after, carry out following steps operations: (1) the fine oil-resistant rubber insert capacity of bulk fourth of purchasing; (2) the fine oil-resistant rubber insert of above-mentioned fourth is carried out cutting according to the outline of the upper surface of bottom iron core lapping structure; (3) smear the outline of the upper surface of bottom iron core lapping structure with silicone sealant; (4) the fine oil-resistant rubber insert of the fourth that cuts is taken off, cover the zone that scribbles silicone sealant on the bottom iron core; (5) smear the upper surface of rubber blanket with silicone sealant; After having completed above-mentioned steps, the production that continues to complete the upper strata iron core according to traditional amorphous iron core assembly technology gets final product.Compared with prior art, the present invention has significantly improved security of operation and the reliability of amorphous alloy transformer, has reduced the noise of amorphous alloy transformer.
