E62-3ph Series 系列

The E62-3ph capacitors stand out by their high AC-voltage load capacity. They were designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion in the frequency range up to 1 kHz.

Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength.

The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation. As an E65-3ph option, they can also be filled with neutral insulation gas (Nitrogen). The finger-proof CAPAGRIP™ screw terminals (rated IP20) make for simple and reliable connections and easy addition of IP20-resistors or reactors for discharge.

The standard design has a long-term stable capacitance with ± 5% tolerance. Tighter tolerances are available on request.

Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life.

E62-3ph 电容器因其强大的交流电压负载能力脱颖而出。它们专为极端或复杂运行条件下的高端应用而设计，例如风电和 UPS 应用中的交流滤波和功率因数校正，以及针对三相电中1 kHz频率范围内高或异常的谐波失真水平的谐波滤波。

由于特殊的结构，电容具有非常低的串联电阻和小的自感。我们的基本设计原则 - 首选具有相对较大直径的短绕组元件 - 以及在许多型号中使用的薄膜波切技术，可提供高有效值和浪涌电流强度。

三个电容元件在电容内部呈三角形连接；环保的植物油填充物，用于优化散热和改善内部绝缘。作为 选项，也可填充中性绝缘气体（氮气）。可触摸CAPAGRIP™ 螺钉端子（额定 IP20）可实现简单可靠的连接，并可轻松添加 IP20 电阻器或电抗器以进行放电。

标准设计容量长期稳定，容差± 5%。可应要求提供更严格的公差。

良好的自愈特性和内置的压力保护 (“BAM”) ，可确保电容安全运行、并在过载或使用寿命结束发生故障时受控断开。
