General description
Self-healing type low voltage shunt capacitor,made of the advanced metallized film,is produced strictly in accordance with the National standard and IEC standard by the introduced advanced foreigh techniques and equipment The device is mainly suitable for low voltage electric network to improve power factor,reduce reactive loss,and better the voltage quality.
Main characteristics
1.Small volume and light weight It is only 1/4 and 1/5 of the volume of the outdated product respectively
2.Low loss with the actual loss less than 0.1%,the capacitor,itself,has low consumption of energy,little radiation effect.
3.Excellent self-healing So as to continue the normal operation,therefore the reliability is improved greatly.
4.Safety Equipped with self-diseharging resistant and safety devices inside,it is safe and reliable.
5.Without oil leakage in order to avoid oil leakage during operation So as to protect the environment,it employs the microcrystalline wax as the impregnant,which remains solid atorinary temperature and has a drip melting point higher than 70~C.
Main technical characterlstles
1.service conditions:ambient temperature-25℃~45℃,humidity≤85%.and altitude lower than 200m.
2.Rated voltage:250VAC,400VAC,525VAC,690VAC,750VAC,1050VAC.
3.Rated output:l~30kvar.
4.Capacitance Tolerance:0~+l5%.
5.Tangent of the loss angle:with the power frequency rated voltage,tgδ≤O.1%at 20V.
6.Withstand voltage:capable of withstanding 1.75 times of rated voltage between poles for 10s,R≥1000MQ.
7.Max allowable voltage:1.10 times of the rated voltage.
8.Mas allowable current:1.30 times of the rated curret.
9.Self-discharging characteristics:Apply√2 Un DC voltage to the device and switch off the power supply for 3min,and then the residual voltage is 50V or less.
10.Standards:In Conformity with GBl2747-1991,IEC83l-1988.
