Abstract
The invention provides a transformer device, which comprises an iron core and windings, wherein the number of turns of the windings is increased, the size of the iron core is increased, the iron core material of silicon steel sheets is selected, when a power transformer is manufactured, the windings of the windings are as compact and solid as possible, the silicon steel sheets are required to be arranged and inserted tightly and standardly, the windings and the silicon steel sheets are required to be as compact as possible, and after the source transformer is wound, paint dipping and drying treatment are carried out, so that the primary no-load current of the transformer is reduced, the no-load loss and the heat loss of the transformer are reduced, and the alternating current dry noise.
Description
Technical field
The present invention relates to a kind of apparatus of circuit, especially a kind of apparatus of transformer.
Background technology
During the transformer secondary output open circuit, elementaryly still have certain electric current, this part electric current is called no-load current, no-load current is made up of magnetizing current (generation magnetic flux) and core-loss current (being caused by core loss), recommendation and a large amount of practice according to related standards show, the maximum of the no-load current Iio of small-power power transformer should be no more than 5～8% of Ii, if no-load current surpasses 10% of rated current, the loss of transformer will increase, when no-load current surpass rated current 20% the time, transformer just can not use, because its temperature rise will be above permissible value, operating time is long slightly, and serious will cause burnout failure.
Summary of the invention
The present invention is directed to the defective of prior art, a kind of apparatus of transformer of science is provided.
To achieve these goals, the present invention takes following measure to realize:
A kind of apparatus of transformer, comprise iron core, coiling is characterized in that increasing umber of turn, and increase core dimensions, select the iron core material of silicon steel sheet for use, when making power transformer, each winding coiling should be tried one's best tight, sturdy, silicon steel sheet answer socket closely, standard, the compactness of should trying one's best between winding and the silicon steel sheet after source transformer coiling is finished, is carried out the device that dipping lacquer, oven dry are handled.
The present invention has following characteristics with respect to prior art: the present invention has reduced the primary no-load current, reduces no-load loss and transformer thermal losses, and has reduced the dry sound of transformer alternating.
Embodiment
Under the identical situation of other technical specification of power transformer, the number of turn of elementary winding is many more, no-load current is just more little, under the identical situation of other technical specification of power transformer, core dimensions (sectional area and the length of magnetic path) is big more, no-load current is more little, core material can divide low μ by permeability (μ), middle μ and high μ three classes, under the core dimensions situation identical with other technical specifications such as umber of turns, magnetic capacity is high more, no-load current is more little, and generally speaking, silicon steel sheet is thick more, resistance between the adjacent silicon steel disc is more little, eddy current loss in the iron core of energising back is big more, and the elementary no-load current of transformer is also big more, and the no-load current of general miniature motor is about the 30%-70% of rated current, the no-load current of large and medium motor is about the 20%-40% of rated current, the no-load current value of general motor is about 0.8 times of motor rated capacity kilowatt number, and is medium-sized, the no-load current of 4 or 6 pole motors is exactly 0.8 times of motor capacity kilowatt number.
In the reality, the present invention can reduce no-load transformer electric current 30%-40% and reduce no-load loss 30%, and reduces the dry sound of transformer alternating 10-20 decibel greatly.
