Embodiment 1

[0012] Such as figure 1 As shown, a low-loss transformer according to the present invention includes a casing 1, an oil tank 2, an iron core and a coil, and the iron core and coil are assembled into a device through body insulation and lead wires and placed in the oil tank 2 behind, The winding on the iron core is a copper winding, and the copper winding is an alloy copper. The formula of the alloy copper includes silver, silicon, and nickel, and the weight percentage content of each component is: silver: 1.5%, silicon: 0.01% , Nickel: 0.01%, and the balance is copper. Using the above materials, the no-load and load losses can be significantly reduced, and it has been proved by experiments that the present invention reduces the no-load loss by an average of 10.25% and the no-load current by 37.9% compared with GB / T6451 %, and the operating cost is reduced by an average of 18.9%, so it has the characteristics of energy saving. Wherein, the oil tank 2 adopts a fully sealed stru...

Abstract

The invention relates to the technical field of a transformer of electric equipment, in particular to a low-consumption loss transformer. The low-consumption loss transformer comprises a shell, an oil tank, an iron core and a coil, wherein the iron core and the coil are arranged in the oil tank after being assembled into a device body through device body insulation lines and guide lines, a winding on the iron core is a copper winding, the copper winding is made by of alloy copper, a formula of the alloy copper comprises silver, silicon and nickel, thus the no-load loss and load loss can be obviously reduced, the cost is lowered, and the resource is saved. In addition, the low-consumption loss transformer disclosed by the invention has the characteristics of energy saving, long service life, high operation reliability, small occupied area and the like.

Description

technical field [0001] The invention relates to the technical field of power equipment transformers, in particular to a low-loss transformer. Background technique [0002] Due to the unreasonable design of the current transformers in terms of mechanical properties and electrical aspects, the existing transformers have large no-load losses, large no-load currents, energy saving, and performance stability. to satisfy the market's needs. Contents of the invention [0003] The purpose of the present invention is to provide a low-loss transformer capable of reducing no-load loss, no-load current loss, etc., and making the performance and structure more stable and reliable. [0004] In order to solve the existing problems of the background technology, the present invention adopts the following technical solutions: a low-loss transformer, including a casing, an oil tank, an iron core and a coil, and the iron core and the coil are assembled into a body and placed behind the devic...
