Multiply Load Capacity-adjustable High Voltage Shunt Capacitor

 

Multiply Load Capacity-adjustable High Voltage Shunt Capacitor
General
Multiply load switched capacitor compensation equipment is primarily based on the conventional high voltage shunt capacitor devices, add specific load switching switch and the capacitor capacity is divided into multiple groups to achieve load capacitor-adjustable capacity. Compared with the original use of mechanical-switch or adjust the way of connection lines load capacity-adjustable method is more convenient, reliable and safe.
  As the capacity of the capacitor can be divided into many stalls, so compensation was more effective, more suitable for industrial and mining customers, making its power factor to maintain the standard range.
    Load capacity-adjustable devices have main components: the load capacity-adjustable switch, capacitor, discharge coil, zinc oxide arrester, series reactor, pillar insulator, bus bar connection, cabinets and other components.
Groups can show the state capacitor switching and provide the signal in the control room.
The device can be more refined to improve the frequency AC power system power factor, to
reduce line losses, to improve the quality of power supply voltage, and to develop the potential of the power generation equipment.
