Description

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 foreign techniques and equipment. The device is main 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 Small volume and light weight It is only 1/4 and 1/5 of the weight and the volume of the outdated products respectively.
2. Low loss With the actual loss than 0.1%, the capacitor, itself, has low consumption of energy, little radiation, low temperature rise, long service life, and good energy conservation effect.
3. Excellent self-healing performance When a part of the isolation is fed through due to the overvoltage, it is capable of self-healing so as to continue the normal operation, therefore the reliability is improved greatly.
4.Safety Equipped with self-discharging 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 atordinary temperature and has a drip melting point higher than 70.


Main Technical Characteristics

1.Serivce conditions: ambient temperature -25~50, humidity85%,and altitude lower than 2000m.
2.Rated voltage: 250VAC, 400VAC, 525VAC, 690VAC, 1050VAC, 1200VAC.
3.Rated output: 1~60Kvar.
4.Capacitance Tolerance: 0~+15%.
5.Tangent of the loss angle: With the power frequency rated voltage. tg δ0.1% at 20.
6.Withstand voltage: capable of withstanJing1.75times of rated voltage between poles for 10s,R1000MΩ.
7.Max allowable voltage: 1.10times of the rated voltage.
8.Max allowable current: 1.30 times of rated current.
9.Self-discharging characteristics: Apply2 Un DC voltage to the device and switch off the power supply for 3m,and then the residual voltage is 50V or less.
10.Standards: In conformity with GB 1274-1991, IEC 60831-1996.
