Product working principle
HZ series intelligent capacitors are mainly composed of intelligent components, zero-crossing switching and switching devices, low
-voltage power capacitors, and collection of internal temperature and current signals of capacitors and capacitors, A schematic diagram of the electrical principle of working together and supplementing the smart capacitor product (as shown in Figure 1 and Figure 2).
Switching switch electrical contact disconnected state voltage zero-crossing operation low-voltage power capacitor, the current zero-crossing returns the low-voltage power capacitor when the contact is closed.
Manual control: Manually control the commissioning or return of low voltage power capacitors.
Automatic control: The low voltage power capacitor is automatically put into operation or returned according to the measuredvoltage, reactive power, power factor, and the set values of these physical quantities.
Communication control: External controller, performing or returning a low-voltage power capacitor according to the controller's control communication command; External display, the operating state of the low-voltage power capacitor, the fault state, and the power factor value of the compensation system are displayed according to the transmission communication command that the display receives the smart capacitor put-in or return status.
