增强型电力电容器FML(R460)
具有低损耗的自修复电容器金属化聚丙烯电介质,不含浸渍液体。安装在矩形钢板外壳中,其外部有放电电阻,由端子保护。
这些电容器专门设计用于谐波电平,即使电压很低,也足以产生超过标准允许的最大过载值的过电流和过电压。
PRISMATIC CAPACITOR技术
LIFASA电容器的制造采用先进的技术,来自对制造工艺的深入了解,也来自非常严格的实验室和研发测试。多年积累的丰富的安装经验使我们能够在新的设计中结合必要的特性来优化产品的使用。电容器由低损耗聚丙烯薄膜缠绕的电容元件组成。这种电介质是真空金属化的,使其具有优良的自愈特性(MKP)。元件被高介电性能的热硬化树脂覆盖,并且不填充油。连接元件以获得所需的无功功率并安装在钢箱内。元件和壳体之间的空隙填充有不易燃、惰性和无毒的材料。每个元素单独保护。此构造系统避免了电容器爆炸的风险。
好处
- 电容器是干式的,因此在生态上是安全的:不存在浸渍液体泄漏的可能性。
- 损失特别减少:低于0.05%(<0.5 W / kvar)。
- 电容器是一种自我修复类型:在电介质击穿的情况下,例如,由于瞬态过电压,自愈机制使金属电极在击穿点周围蒸发,使电容器继续正常工作。
- 它们的重量和体积非常低,可以毫无问题地安装在任何地方。
- 电容器使用强大的端子,可确保快速安全的连接。
- 电容器,覆盖不同的系列,广泛的功率和电压,以满足多样化的要求
Reinforced Power Capacitor FML (R460)
Self-healing capacitors with low losses metallized polypropylene dielectric without impregnant liquids. Mounted in rectangular sheet steel plate enclosure having discharge resistors connected to the terminals, which are protected by the cover.
These capacitors are specially designed for a harmonic level, which, even if low, is enough to produce overcurrents and overvoltages exceeding the maximum overload values allowed by the standards.
PRISMATIC CAPACITOR TECHNOLOGY
LIFASA capacitors are manufactured using the most advanced technologies, coming from an in depth knowledge of the manufacturing process and also from very strict laboratory and R+D tests. The enormous experience in installations, acquired over many years, allow us to incorporate in the new design the necessary characteristics to optimize the use of the product.Capacitors are composed of capacitive elements wound from low loss polypropylene film. This dielectric is vacuum metallized, what gives it an excellent self-healing characteristic (MKP).Elements are covered with a thermo hardening resin of high dielectric properties and are not oil filled. Elements are connected to obtain the required reactive power and are mounted in steel cases. Void spaces between elements and the case are filled with a non-flammable, inert and non toxic material. Each element is individually protected.This construction system avoids any risk of explosion of the capacitor and meets all the tests specified in the IEC 60831-1 and IEC 60831-2 standards.
ADVANTAGES
- Capacitors are dry type and consequently ecologically safe: there is no possibility of impregnating liquid leakage.
- Losses are specially reduced: lower than 0.05% (< 0.5 W/kvar).
- Capacitors are a self-healing type: in case of a dielectric breakdown, due for example, to a transient overvoltage, the self-healing mechanism vaporizes the metallic electrode around the breakdown point, allowing the capacitor to go on working normally.
- Their weight and volume are very low, allowing them to be installed everywhere without problems.
- Capacitors use strong terminals that guarantee a fast and safe connection.
- Capacitors, cover with their different series, a wide range of power and voltages to satisfy the most varied requirements.
