Utility model content
Technical problem to be solved in the utility model is for the above-mentioned technical problem existing for the reactor of existing large power power electronic appliance filtering and provides a kind of big current radio-frequency rector, this big current radio-frequency rector is according to the basic circuit framework of various photovoltaic DC-to-AC converter and operation principle, the performance requirement analyzing its inductance element used that matches and the pluses and minuses of inductance element be widely adopted at present, in conjunction with the newest fruits of existing magnetic material, adopt high performance magnetic material in conjunction with inductor design gimmicks such as mixed magnetic circuit technology, promote the efficiency of photovoltaic DC-to-AC converter, reduce the noise of reactor, and effectively reduce volume, thus reduce costs.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of big current radio-frequency rector, comprise the magnetic core be installed together by upper and lower folder and securing member, described magnetic core becomes hollow structure, two stem stems of described magnetic core are wound with coil, each coil is divided into upper and lower two joints, and upper and lower two nodel line circles are electrically connected by bus-bar, it is characterized in that, described magnetic core is prepared from by the Fe-Si-Al magnetic heart, and described coil adopts aluminum steel to make around mode so that 8-shaped is vertical.
Owing to have employed technical scheme as above, big current radio-frequency rector of the present utility model, compared with the reactor of existing large power power electronic appliance filtering, has the following advantages:
1. provide a kind of photovoltaic DC-to-AC converter efficient, low noise reactor, improve the efficiency of photovoltaic DC-to-AC converter, simultaneously under raising existing product performance technologies Parameter Conditions, greatly reduce existing production cost, to realize environmental protection and ideas of energy-saving simultaneously.
2. magnetic core adopts high-performance magnetic heartwood material, compared with ordinary silicon steel disc, effectively reduces core loss.
3. inductance coil adopts aluminum steel to found winding technologe, improves radiating condition, reduces the stary capacity of coil
4. compared with the reactor done with other producer domestic, the utility model is in efficiency, noise, temperature rise, small product size, be better than contrast product in the key indexs such as cost, and the utility model is detected by German TUV, properties of product meet IEC.
Concrete contrast index is in table 1
