Description
Technical field
The utility model relates to a kind of transformer, particularly the nanocrystalline transformer of a kind of inverter type welder.
Background technology
Inverter is the capital equipment of inverter type welder, and transformer is the heart of inverter, and transformer device structure comprises magnetic core and coil.Generally in high frequency inverter, adopt ferrite as core material, though FERRITE CORE high-frequency loss is lower, the magnetic characteristic of its low-frequency range is not so good, again because its saturation induction value is lower, the volume and weight of magnetic core is still larger, in addition, ferritic Curie temperature is lower, poor heat stability, the slightly high magnetic induction value that causes of temperature reduces, easily saturated, unstable working condition, is not suitable for using under high-frequency high-power.
On high-frequency high-power inverter, the nanocrystalline core material as transformer of existing most employing, because nanocrystalline material has advantages of that magnetic induction value is high, magnetic permeability is high, loss is low, Curie temperature is high, the transformer application of its manufacture, on inverter, has played great role to the raising of power supply reliability.
But still there are some defects in existing nanocrystalline transformer in the market: 1, magnetic core adopts the nanocrystalline strip coiling of 28-32 μ m to form, and power loss is still higher, and operating frequency is the highest can only reach 30KHZ; 2, winding wire adopts enamel covered wire, and cost is higher, and the weight of transformer is larger, and cooling rate is slow; 3, coil goes out the joint employing copper aluminum connecting terminal soldering connection of lambda line, often occurs the problem of loose contact when large electric current passes through.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and provide, a kind of power loss is low, operating frequency is high, and lightweight, cost is low, cooling rate is fast, joint contacts the nanocrystalline transformer of good inverter type welder.
The technical solution of the utility model is:
The nanocrystalline transformer of inverter type welder, comprise the Nanocrystalline core with leg, and install around primary coil, the secondary coil on magnet ring, it is characterized in that: described magnet ring is reeled and formed by the nanocrystalline ultra-thin strip of 23-25 μ m, the wire of described primary coil and secondary coil all adopts enamel insulated aluminium wire, and the joint that coil goes out lambda line adopts copper aluminum connecting terminal to freeze and be connected with the aluminium of wire.
The enamel insulated aluminium wire of secondary coil described in the utility model is wrapped with 2 strata imide membranes.
The lambda line that goes out of coil described in the utility model is wrapped with varnished tube, and the joint that goes out lambda line is provided with heat-shrinkable T bush.
The beneficial effects of the utility model are:
1, magnet ring material adopts nanocrystalline ultra-thin strip coiling to form, and power loss reduces by 20%, and operating frequency is the highest can be to 45KHZ;
2, the wire of coil changes enamel insulated aluminium wire into by enamel covered wire, and transformer overall weight is light by 20%, and cost 30% is cooling quick, and is convenient to coiling;
3, the joint that coil goes out lambda line adopts connections of freezing of copper aluminum connecting terminal, the problem of loose contact when solving large electric current and passing through.
