Modular structure
      The intelligent power capacitor has a modular structure, small size, simple field wiring and convenient maintenance. The expansion of the reactive power compensation system can be realized only by increasing the number of modules.
High quality capacitor
      The self-healing low-voltage compensation capacitor is used, and the capacitor has a built-in temperature sensor, which reflects the internal heating degree of the capacitor and realizes over-temperature protection.
Embedded switching switch module
      The smart power capacitor has a built-in switching switch module. The switching switch module is composed of a thyristor, a magnetic holding relay, a zero-crossing triggering conducting circuit and a thyristor protection circuit, and realizes a "zero switching" of the capacitor, ensuring no surge current impact during the switching process, and no operation overvoltage. The switch module responds quickly and can operate frequently.
Perfect protection design
      Intelligent power capacitors have functions such as power failure protection, short circuit protection, voltage phase loss protection, and capacitor over temperature protection to effectively protect capacitors and extend equipment life.
Advanced control technology
      The control physical quantity is reactive power, and the reactive power flow prediction and delay multi-point sampling technology are adopted to ensure that the switching has no oscillation. When reloading, reactive power is fully compensated.
Anti-switching oscillation technology
      The unique design principle is adopted to prevent the controller from crashing and uncompensating or overcompensating the scene to prevent the capacitor from switching.
Automatic compensation of reactive power
      The intelligent power capacitor automatically switches according to the magnitude of the reactive power of the load, dynamically compensates the reactive power, and improves the power quality. Smart capacitors can be used in a single unit or in multiple units.
Human-machine interface friendly
     Display equipment operating parameters such as current, voltage, and reactive power.
     The switching status, the composite switch module fault status, and the communication status are displayed.
     It can also easily realize debugging/working status switching and manual/automatic operation functions.
