1. Altitude: less than 1000m;
2. Ambient temperature: -25ºC~+55ºC;
3. Relative humidity: no more than 85%;
4. The operation site is not allowed to have explosive danger of the medium, the surrounding medium should not contain corrosive and damage insulation gas and conductive medium, is not allowed to be full of water vapor and serious mold.
1. The device can run for a long time under the steady state overvoltage of 1.1 times the rated operating voltage;
2. The device can run continuously under the overcurrent of the capacitor bank whose root value does not exceed 1.3 times the rated current of the capacitor bank;
3. The device uses vacuum contactor to cut, which can be operated frequently;
4. Each set of capacitors is provided with a discharge coil, which can drop the remaining voltage to 50V or less within 5 seconds;
5. Each group of capacitors can be protected by relay or microcomputer protection control unit to achieve overcurrent, voltage imbalance, undervoltage and overvoltage protection of the capacitor bank. When a group of capacitors has a fault, it can cut off this group of capacitors without affecting the use of other capacitors;
6. Single capacitor has spray type fuse protection, each group is equipped with lightning arrester operating overvoltage and lightning strike overvoltage protection;
7. Large screen LCD controller, real-time display system voltage, current, power factor; With RS232/RS485 standard communication interface, and can achieve "four remote" function;
8. Each group can be configured with a reactor to suppress the closing inrush current or suppress harmonic amplification.
