Embodiment Construction
[0009] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:
[0010] see figure 1 , the rural network low-voltage lifting device of the present invention includes an electrically connected single-phase EN series controller, a line protection unit and a capacitor, a thyristor composite switch circuit, a molded case circuit breaker, a lightning arrester and a current transformer, wherein the controller adopts a feedback type Monitoring, using the real-time voltage of the load as the switching physical quantity, completes signal data collection, calculation, and control output within 20ms. After the switching switch receives the switching command, it completes zero current input within 10ms, and there is no inrush current in switching. There is no impact on the power grid to ensure real-time tracking of switching.
[0011] Composition of the device: The device of the present invention is composed of an ...
