High Voltage Capacitors Equipment
Assembled High Voltage Shunt Capacitor Complete Set
Application:
The Assembled High Voltage Shunt Capacitor Complete Set is primarily used in three-phase AC power systems with a frequency of 50Hz and voltage levels ranging from 6kV to 66kV. Its main purpose is capacitive reactive power compensation to improve power factor, enhance grid voltage quality, and reduce line losses. The product offers advantages such as easy installation, safe operation, and a small footprint, making it particularly suitable for installation in compact spaces.
Structural Features:
The compact shunt capacitor unit consists mainly of high-voltage shunt capacitors, series reactors, discharge coils, zinc oxide surge arresters, isolation grounding switches, and other components. The unit, along with its accessories, is installed on-site, with safety protective fences around the device. The unit is generally wired in a single-star or customized design based on customer requirements. Relay protection methods typically include open delta voltage protection for devices up to 10kV and differential voltage protection for 35kV devices, with customization available according to specific user needs. In addition to the aforementioned components, the 10kV capacitor bank also includes sectional switches, which must be operated under no-load conditions. To engage the entire capacitor capacity, the sectional switches are set to the closed position before commissioning. For selective capacitor operation, the sectional switches are set to the open position, allowing for equal (1/2) or unequal (1/3, 2/3) capacitor capacity compensation.
Main Technical Performance:
Device capacitance tolerance: The measured capacitance of each phase compared to the nominal capacitance does not exceed 0 to +5%, with a ratio between the and phase capacitances not exceeding 1.02.
The device can operate continuously at 1.05 times the rated voltage.
The device can operate continuously under root mean square currents not exceeding 1.3 times the rated current due to overvoltage and harmonics.
