1.变频传动变频器(Variable-frequency Drive Device )


变频器是使用变频技术与微电子技术,经过改动电机任务电源频率方法来控制交换电动机的电力控制设置装备摆设。变频器次要由整流(交换变直流)、滤波、逆变(直流变交换)、制动单位、驱动单位、检测单位、微处置单位等构成。变频器靠外部IGBT的开断来调解输入电源的电压和频率,依据电机的实践需求来提供其所需求的电源电压,进而到达节能、调速的目标,随着产业主动化水平的不时进步,变频器也失掉了十分普遍的使用。低磁导率纳米晶大共模电感铁芯实用于≤1000V的高压变频器,能无效克制变频器发生的共模搅扰。

Frequency converter is electricity control equipment which uses variable and micro electronics technologies to control an AC motor through changing frequency of power supply for the motor. It is composed of rectifier (AC-DC), filters, inverters (DC-AC), brake unit, drive unit, test unit, micro-processing unit, etc. It adjusts the output voltage and frequency by switching internal IGBT and provides required power supply voltage for energy conservation and speed control. It is widely applied as the industrial automation improves continuously. Low-frequency common mode choke cores are used for low voltage inverter(≤1000V) and effectively suppress the interferences.

2.光伏发电逆变器( PV Inverter)


       实用于500kW、1MW大功率会合式光伏逆变器。高磁导率大共模电感铁芯实用于大功率光伏逆变器交换侧EMC滤波,应用铁芯的高电感能无效增加铁芯数目到达很好的滤波结果;低磁导率大共模电感铁芯实用于大功率光伏逆变器直流侧EMC滤波,该类铁芯电感频率特性好,能无效抵挡不屈衡直流重量,防止铁芯饱和形成的废弃。

AT&M CMC Cores are applied to 500KW & 1MW centralized PV inverters. High-permeability CMC Cores are applied to EMC filters near to AC output of high-power PV inverters. The better EMI suppression effect can be reached by less quantity of CMC cores due to high induction performance. Low- permeability CMC cores are applied to EMC filters near to DC output of high-power PV inverters. Low-permeability CMC cores have excellent inductance performance depend on frequency and effective anti-DC bias performance to avoid the damage from saturated inductance.

3.风力发电变流器(Wind Power Converter )


实用于1MW、1.5MW、2MW、3MW等直驱和双馈变流器。接纳数只纳米晶铁芯堆垛组装的单匝扼流圈是轴承电流题目的无效处理方案,也是风力发电、大范畴变速驱动及其他使用发生的大电流搅扰(峰值从几十到100多安培)招致的超高共模乐音题目的无效处理方案。这些题目通常体现为高频尖峰电流的方式。ku网址科技股份有限公司消费的共模组件能轻松平安的集成到这些现有范畴处理呈现的题目。共模组件可由两种差别内径的磁环拆卸而成。组件按所需的饱和电流和电感定制设计,容许单选磁环,也可数只组装(最多7只)。

Meanwhile it is also effective EMI solution caused by big current interfere (dozens to more than 100 A) for wind energy, variable-speed drive and other application. All those problems usually are reflected in high-frequency peak current and easily solved by AT&M stacking CMC cores design. The stacking ways are depend on saturated current and induction. Customer can select one core or stacked cores(up to 7 cores).

5.气体绝缘开关设置装备摆设(Gas insulated switchgears)


气体绝缘开关设置装备摆设(GIS)黑白常牢靠的电力传输网络的组件。在过来的几年,零碎电压到达1.2千伏。GIS的切换操纵能够招致风险的瞬态电压(VFTO)。在外部导体上同心的装置纳米晶铁芯作为单匝的电抗器,可以无效地克制这些毁坏性的高频(~15 MHz)电压。其他的铁芯资料如铁氧体不克不及处理这个题目。

GIS is reliable equipment for power transmission. The system voltage has been up to 1.2KV during past years. The switch operation of GIS may lead to danger VFTO. The reactors with nanocrystalline cores can prevent the damage from high frequency voltage (~15 MHz). Other materials cannot solve this problem such as ferrite.

6.高能粒子减速器(High energy particle accelerator)


由于纳米晶具有至多1.2特斯拉的高饱和磁通密度,得当的纳米晶铁芯是同步盘旋减速器空声调谐组件的首选处理方案。在十分有限的空间停止的粒子束偏转集束器或紧缩集束器,经过运用纳米晶铁芯,所需的长度比铁氧体铁芯通常可以增加50%,但缺陷是任务时期功耗明显添加。不外,由于他们的低阻抗,纳米晶铁芯也防止了与离子束倒霉的交互作用,因而,纳米晶铁芯在全世界的几个粒子束减速器设备中得以运用。

Due to the high saturation flux density of at least 1,2Tesla suitable nanocrystalline cores are the preferred solution for the tuning elements in synchrotron cavities. Related applications like particle beam de-bunchers or bunch compressors are often very much limited in space. By the use of nanocrystalline cores, the required length compared to Ferrite cores can be reduced by typically 50% - but with the disadvantage of significantly higher power consumption during operation. But due to their low impedance, the nanocrystalline cores also avoid unfavorable interactions with the ion beam and thus, they are used in several particle beam accelerator installations worldwide.
