Future proof retrofit for old traction capacitors in MP technique.
Detailed description (please consult for model parameters)
The dedicated retrofit for MP-traction-capacitors
The capacitors of our SR17™ series were developed especially for the maintenance of older traction converters manufactured in the 1970s?1990s. By consequent development of our well-proven MKP-technologies, we managed to place self-healing DC-capacitors with very high energy density and stability of capacitance into can dimensions smaller than, or identical to, those of the traditional MP-capacitors (SIEMENS/EPCOS codes B25353), which makes them ideal drop-in replacements for maintenance and retrofit programmes. Moreover, the low-loss polypropylene dielectric permits a far higher AC ripple load than with the conventional MP-capacitors.
Our SR17™ are housed in a hermetical stainless steel cylinder. As opposed to the oil-filled MP-models, these are filled with an eco-friendly solid resin which does not only make them safe against leakage of liquids but also insensitive to the shocks and vibrations common in traction applications. The same applies to their robust plastic insulators.
As a result, the SR17TM is not only new, but far more reliable and less sensitive than the capacitor it replaces.
SR17™ 系列电容专为维护1970至1990年代制造的旧牵引变流器而开发。通过经充分验证的MKP技术的后续发展，我们将具有高能量密度和容量稳定性的自愈直流电容装入尺寸小于或等于传统的MP电容(SIEMENS/EPCOS 代码 B25353)的外壳中，使之成为维护和改造计划的理想替代品。与传统的MP电容相比，低损耗的聚丙烯介质具有更高的ＡＣ纹波负载能力。
