Self-Healing Low Voltage Shunt Capacitor (BSMJ0.4-15-3)

Product Description

BSMJ, BCMJ, BZMJseries capacitors adopt imported dull polish rust-resisting material as casing, have small size, light weight, use metallized membrane as medium, features low loss, low temperature rise and excellent sel-healing performance. Capacitor is mounted with discharge resistance and pressure type explosion protection inside, is safe and reliable.

This series of capacitors are mainly used for parallel connection with low voltage grid to increase power factor, decrease reactive loss, improve voltage quality, is a new type energy saving products recommended by the country.

Working conditions:
Altitude: No more than 2000m;
Ambient temperature: -25º C~45º C;
Humidity: Less than 85%;
Installation site: No harmful gas, no explosive dust;
Content of harmonic in power supply: Less than 10%; When more than two capacitors are set simultaneously, spacing should be over 50mm, effective heat dissipation measures should be taken at high temperature in summer.

Technical Index:

Climate category: -25º C~+45º C;
Rated voltage: 230VAC~690VAC;
Rated capacity: 1Kvar~50Kvar;
Capacity tolerance: -5~+10%;
Tangent of the loss angle: With the power frequency rated voltage tg¦Ä¡Ü0.1% at 20;
Withstand voltage inter-electrodes: Capable of withstand 2.15 times of rated voltage between poles in 5s.
Max permissible over-voltage: 1.10 times of the rated voltage.
Max permissible over-current: 1.30 times of the rated current.
Self-discharging characteristics: After power off for 3min, the residual voltage is 70V or less.
Implementation Standards: In conformity with GB/T12747.1-2004 IEC60831-1: 1996.

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It is only 1/4 and 1/5 of the weight and the volume of the outdated products respectively.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.
3. Excellent self-healing performance
When a part of the isolation is ted through due to the over voltage, it is capable of self-healing so as to contiue the normal operational, therefore the raliability 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 state at noraml temperature and has a drip-melting point higher than 70º C.
