Description
Technical field
The utility model relates to a kind of coiled silicon steel sheet structure being applied to the low-frequency transformer of 2 ~ 10VA, particularly relates to a kind of energy-economic transformer coiled silicon steel sheet structure.
Background technology
Along with the development of society, market is very huge to instrument, instrument and medicine equipment, electromechanical equipment, consumer electronics demand, and the relevant device produced of China is annual all more than 1,000,000,000 in recent years, and these equipment considerable part on power supply adopts low-frequency transformer.
At present, the EI series in GB14411 then used by China's silicon steel sheet, and conventional specification has EI28, EI35, EI41, EI48, EI57, EI66, EI76, EI86, EI96, EI150 etc.The EI33 iron core that the transformer of 2-10W is conventional, as shown in Figure 3, wherein shade part is unserviceable waste material in punch process to its dimensions, and account for 20% of total raw material, its raw-material utilance only has 80%.Fold thick 20mm by every transformer core to calculate, need raw material 0.14kg, excision waste material 0.028kg then 100,000,000 transformers by generation 100,000,000 X0.046538905 kilogram=2800 tons, be equivalent to the waste of more than 3,000 ten thousand yuan, therefore at current energy saving and cost lowering, under advocating the theme of environmental protection, how to improve stock utilization and change this waste and become particularly important.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides one to make transformer performance more stable and stampings is few, improves the energy-economic transformer coiled silicon steel sheet structure of stock utilization.
The technical scheme that the utility model adopts is: the utility model comprises the E type silicon steel sheet and two blocks of I type silicon steel sheets that two pieces of symmetries connect, in the space that described I type silicon steel sheet is formed after being separately positioned on two pieces of described E type silicon steel sheet docking, the width L of described E type silicon steel sheet is 33mm, length n is 27.3mm, described E type silicon steel sheet two side column width e and intermediolateral column width a are respectively 5.5mm and 11mm, length h is 21.8mm, described space all described I type silicon steel sheet is 5.5mm, and described I type silicon steel sheet length l is 33mm.
The junction of the described E type silicon steel sheet that two pieces of symmetries connect all forms broken line.
Be positioned in described space on described I type silicon steel sheet lower position and also leave space, the length f in described space is 10.6mm, and width is identical with described space.
The beneficial effects of the utility model are: because the utility model comprises E type silicon steel sheet and two blocks of I type silicon steel sheets that two pieces of symmetries connect, in the space that described I type silicon steel sheet is formed after being separately positioned on two pieces of described E type silicon steel sheet docking, the width L of described E type silicon steel sheet is 33mm, length n is 27.3mm, described E type silicon steel sheet two side column width e and intermediolateral column width a are respectively 5.5mm and 11mm, length h is 21.8mm, described space all described I type silicon steel sheet is 5.5mm, and described I type silicon steel sheet length l is 33mm.Compared with prior art, the utility model can make two blocks of described E type silicon steel sheets and two blocks of described I type silicon steel sheets when making this coiled silicon steel sheet structure simultaneously, described I type silicon steel sheet matches with described E type silicon steel sheet, under the condition that other conditions are all identical, its iron circuit obtains optimization, and magnetic resistance obtains reduction, the balanced resistance everywhere of magnetic circuit, umber of turn can be reduced on year-on-year basis and reduce the consumption of copper cash, more saving material cost, reducing the consumption of resource.
The junction of the described E type silicon steel sheet connected due to two pieces of symmetries all forms broken line.So, when making the utility model, the symmetry of described two blocks of E type silicon steel sheets can be ensured, greatly accelerate the progress of processing, increase work efficiency, save production cost.
