Model meaning

 Normal operating conditions

♦ Altitude: ≤ 2000m;
♦ Ambient temperature: -25 ~ +55℃:
♦ Relative humidity: no more than 85%:
♦ No explosive medium is allowed in the operating place. The surrounding medium should not contain corrosive and insulation-damaging gas and conductive medium. It is not allowed to be full of water vapor and serious mold.

Product characteristics

♦ The device can run for a long time under a steady overvoltage of 1.1 times the rated working voltage:
♦ The device can run continuously under the over-current that the root mean square value does not exceed 1.3 times the rated current of the capacitor bank:
♦ The device adopts vacuum contactor for switching, which can be operated frequently;
♦ Each group of capacitors is equipped with a discharge coil, and the residual voltage can be reduced to less than 50V within 5 seconds;
♦ Each group of capacitors can be protected by a relay or a microcomputer protection control unit to achieve overcurrent, voltage imbalance, undervoltage and overvoltage protection of the capacitor bank. When a group of capacitors fails, the capacitors in this group can be cut off without affecting the use of other capacitors
♦ A single capacitor is protected by spraying fuse, each group is equipped with a surge arrester to protect against overvoltage and lightning overvoltage:
♦ Large-screen LCD display controller, real-time display system voltage, current, power factor; with RS232/RS485 standard communication interface, and can realize the “four remote” function:
♦ Each group can be equipped with reactor to suppress closing inrush current or harmonic amplification.

Main technical parameters

♦ Rated voltage: 6-10kV;
♦ Rated frequency: 50Hz;
♦ Rated capacity: 100-10000kvar;
♦ Number of groups: 1-5 groups;
♦ Parameter selection of reactor: suppress the closing inrush current, the reactance rate is 0.1-1%; suppress the harmonic above 5 times, the reactance rate is 6%; suppress the harmonic above 3 times, the reactance rate is 12%
