HEPTA-LITZ AIR CORED INDUCTORS
PERFECT LAY HEXAGONAL WINDING | |
 |
|
Solen Inc. was the first inductor design company to introduce inductors made with Hepta-Litz conductor. Most of the time, until now, only one parameter was considered for designing crossover network inductors and that is d.c. winding resistance. The problem is that music is far from being d.c. and other non linear losses arise from a.c. frequency which can increase the a.c. winding resistance many times the d.c. value, even at audio frequency. Let us consider some of those losses.
As the frequency increase, additional power losses occur in the winding due to eddy currents in the conductors and by the magnetic fields within the winding. In the design of inductors both skin effect and proximity effect need to be considered. Both effects depend on the ratio of the conductor diameter to the penetration depth of the electrons.
Solen 是第一个将利兹线应用在电感的公司 . 至今大多数的时间 , 设计分音器电感时唯一考虑到的参数只有线圈的DC电阻 . 问题在改变音乐的因素 , AC电阻的非线性损耗上升远大于DC电阻 , 甚至于音频 , 让我们考虑到那些损耗.
如频率升高 , 线圈内会产生额外能量的损耗 , 那是由于导体内的涡电流及线圈内的磁埸 , 在设计电感时必须考虑集肤效应和邻近效应 . 这两种效应是否显着 , 取决于导体横截面尺寸与电磁波在导体中透入深度的比值 . |
|
| Skin Effect 集肤效应 |
|
Skin effect is the tendency for the alternating current to flow near the surface of the conductor as the frequency increase. It is due to eddy currents in the conductor which arise from the alternating magnetic field associated with the current in the conductor itself.
导体中有交流电通过或者处于交变电磁场中时 , 由于电磁感应 , 使电流或磁通在导体中分布得不均匀 , 愈近表面处其电流密度或磁通密度愈大 . 频率越高 , 导体的电导率和磁导率越大 , 趋肤厚度就越小 , 这时祗要导体截面稍大 , 趋肤效应就会相当显着 . |
|
| Proximity Effect 邻近效应 |
|
Proximity effect is the tendency for the alternating current to flow and return along the lenght of each conductor within the winding in such a way as to oppose the magnetic field of the winding as the frequency increase. It is due to the eddy currents in the conductor which arise from the alternating magnetic field interaction of the other conductors within the winding.
载有交流电的导体 , 其磁场会影响到与它相距较近的其他载流导体 , 使电流及磁通分布不均匀 , 使导体电阻加大 . |
|
| Litz Conductor 利兹线导体 |
|
In order to minimize those losses, we have to replace the solid conductor with a number of separately insulated smaller conductors twisted together, the Litz conductor. The reduction of the conductor diameter along with the increase in the number of twisted insulated conductors which tends to occupy all possible positions in the cross section of the resulting conductor are very effective in reducing both effects. The smaller insulated conductors makes the current to divide uniformly between them thus reducing the skin effect losses. The twist of the smaller insulated conductors cancels the emf's induced by the traverse magnetic field thus reducing the proximity effect losses.
This design concept, Hepta-Litz which consist of 7 twisted insulated conductors, results in equalizing the a.c. resistance to d.c. resistance ratio in the usable audio frequency band which is establishing new standards in inductor quality. The Hepta-Litz Air Cored Inductors Perfect Layer Hexagonal Winding are a clean slate design, based on proven state-of-the-art technology which we have successfully transferred and merged to achieve superiority on all fronts. They will dramatically improve the performance of any loudspeaker by linearizing the inductor reactance curve to the ideal inductor reactance.
为了使损耗降到极低 , 我们用多支细小独立绝缘导体卷绕在一起编成 Litz导体来代替单股导体 . 使导体的横截面尺寸降低 , 将很有效的减低导体的集肤效应及应邻近效应 . 多支细小独立绝缘使电流隔离降低趋肤效应损耗,多支细小独立绝缘横越磁场 , 消除电磁场感应降低邻近效应损耗 .
