上海威斯康BSMJ0.4-25-3 自愈式并联电容器 电力电容器

一、概述 general description

1、体积小、重量轻：由于使用金属化聚薄膜新材料作为介质，体积、重量仅为老产品的1/4或1/5。
2、损耗低：实际损耗角正切值低于0.10%，所以电容自身能耗很低，发热小，温升低，工作寿命长，节能效果更佳。
3、优良的自愈性能：过电压所造成介质局部击穿能迅速自愈，恢复正常工作，使可靠性大为提高。
4、安全性：内装自放电电阻和保险装置。内装自放电电阻能使电容器上所储的电能自动泄放掉，当电容器发生故障时，保险装置能及时断开电源，避免故障的进一步发展，确保使用安全。
5、不漏油：本电容器采用先进的半固体环保型浸渍剂，滴熔点高于70℃，在使用过程中不漏油，避免了环境污染，电容器也不会因漏油而失效。

1.small volume,light weight:it is only 1/4 and 1/5 of the weight and volume of the outdatedproducts resdeotively.
2.low loss:with the actual loss less than 0.1,little radiation,low temperature rise,and goodenergy conservation effect.
3.excellent self-healing performance:when a part of the isolation is fed through due to the over voltage,it is capable of self-healing so as to continue the operation,therefore the reliabilityis improved greatly.
4.safety:equipped with self-discharging resistant and safety devices inside,the inner dischargingresistant can make the attached electric discharged;when thereis wrong with the capacitor,the fuse equipment can cut out the electric power,so that no more trouble with the capacitor,safetyand rcliable.
5.without oil leakage:this product adoped advanced half-solid materials driips miltin-gpoint higher than 70℃,avoid leakge during operation and protect the envirament, the capacitorwillnot no use since the leakage.
