SEC系列电容器

SEC series capacitors

1、产品概述Summary
    SEC系列产品是一款专门针对于有电抗器连接的低压调谐补偿及滤波补偿系统而设计的圆柱形电容器。
    The SEC series low voltage cylindrical capacitor is designed to low voltage tuning or detuning filter system (reactor-connected).
    谐波会加速电力设备绝缘老化,同时谐波叠加后的峰值电压会对金属化薄膜的老化造成较大影响,SEC系列电容器是恩菲索科技从材料选择、设计及工艺多方面考量,针对于谐波含量较高的系统而设计的一款电容器。
    Harmonics will accelerate the insulation aging of power equipment, and the peak voltage after the superposition of harmonics will have a great impact on the aging of metallized film. SEC series capacitor is designed by EFISO technology in terms of material selection, design and process, aiming at the system with high harmonic content.

2、产品特点Feature
    Ø 承受高达200IN浪涌电流;
     Resistance to high inrush current(200In)
    Ø 卷制张力跟踪系统结合端面高频喷金技术,均匀薄膜层间压力,实现金属喷层与镀层的更好接触;
    Variable tension winding system &High frequency spraying system make the tension between the film and the layer more average, and the metalized layer can be more tightly touched with the electroplated coated layer.
    Ø 完善的安全保护技术;
    Perfect safety protection technology
    Ø 干式技术;
    Dry Technology
    电容器采用铝制外壳,内部采用干式结构,注入惰性气体,填充干式树脂,保证产品不会出现漏油、燃烧、爆炸等现象;
    Extrude round aluminum can with inert gas dry type structure without leakage flaming and explosive.
    Ø 内置放电电阻;
    Integrated discharging resistors
    电容器在断开电源后,通过内置放电电阻放电,电压可以下降到50V以下,以确保操作人员的安全;
    Ensure safety, each capacitor should be discharged to 50V below within 3min after disconnecting from the power sources.
    Ø 气体保护;
     Gas protection
    电容器采用高真空处理后注入惰性气体,再在高真空状态下注入特殊配方的树脂以提高电容器的电气性能;
    Gas is perfused into the capacitor after vacuumed procedure. The performance of the capacitor is also improved with the perfusion of resin.
    Ø 自愈合能力
    Self-healing
    采用锌铝复合技术的金属化薄膜电极,当电容器内部由于电气过载或温度过高时,会出现电气击穿现象,击穿点周围的电极产生电离,击穿点使电极介质层气化分离,产生绝缘区,电容器恢复正常工作能力;
    The metalized film electric pole applies to zinc, aluminum composite technology, which minimizes the thickness of the pole. The electrical breakdown phenomenon appears when inside of the capacitor is overheated or EOS. The pole around the breakdown point produces ionization, departs electrode medium layer to from the insulator regions, which recovers the operation of the capacitor.
    Ø 压力保护装置
    Pressure sensitive
    当电容器由于过热、过压、过流或电容器寿命达到终结时,聚丙烯薄膜会产生大量气体,电容器内的压力迅速增加,当压力达到一定值后,顶盖接线柱与内部的连接点机械断开,从而断开电容器电源,有效防止事故的进一步扩大;
    In the event of overvoltage, overcurrent,thermal overload or ageing at the end of the capacitor’s useful service life, an increasing number of self-healing breakdowns may cause rising pressure inside the capacitor. To prevent it from bursting, the capacitor is fitted with an obligatory break action mechanism with rising pressure the case begins to expand, mainly separated from internal connection point, and the current path is interrupted irreversibly.
    Ø 高标准容值精度
    Long term stable capacitance tolerance
    每台电容器出厂之前都会进行冲击电流试验,以确保电容质量的稳定;
    Impulse current testing before delivery. Guarantee the stability.
