E51 Series 系列

High voltage, low inductance, AND longest possible operation without failures? Here we go.

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high-voltage capacitors are filled with oil, and the generous bushings required for clearance and creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor.

Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread.

Along with their very good ratio of capacitance to volume, these capacitors do also have high pulse strength and very good self-healing characteristics without loss of capacitance. For the sake of optimised self-inductance, the E51s are made without safety mechanism; by clever internal design they can be laid out and rated in such manner that partial dielectric discharges and consequential risk of failures in the customer?s application are reduced to a minimum.

高电压、低电感和最长可能的无故障运行？请看这里。

在一般的电力电子应用中，特别是在具有较高电压、低电感的缓冲及放电电路中，对电容低电感的需求往往会遇到问题：传统的高压电容器是充油的，绝缘套管需要间隙和爬电距离，还有内部安全机制也大大增加了电容器的自感。

基于数十年电容薄膜金属化方面的经验，ELECTRONICON 利用特殊金属化方案，创造了一系列采用自愈技术的高压电容器。尽管额定电压很高，但我们的 E51 系列采用干式技术制造，没有昂贵的套管。电容采用阻燃性塑料外壳，元件由固体树脂 (PUR) 封装。连接通过带有内螺纹的坚固扁平端子进行。

除了出色的容量体积比之外，这些电容器还具有很高的脉冲强度和良好的自愈特性，而无容量损失。为了优化自感，E51没有安全机构；通过巧妙的内部设计，可以将客户应用中的局部介电放电和相应的故障风险降至相对更低。
