The invention provides an uninterrupted power conditioning device, a
system and a control method, relating to the technical field of electrical
engineering. Fast power supply switching is realized. Operation interruption or device
impact damage during power supply switching is avoided. The switching operation is simplified, and operation error is reduced.
Continuous operation of loads with power uninterrupted is ensured. The uninterrupted power conditioning device comprises a
circuit breaker, an intelligent controller, and a
fast switching device. The
circuit breaker includes a permanent magnetic
actuator and a synchronous shaft. An auxiliary contact is arranged on the synchronous shaft. The intelligent controller includes a control
chip, a storage
capacitor bank, and a power supply module. The control
chip is used for receiving an external opening / closing instruction. The storage
capacitor bank is used for controlling the action of the permanent magnetic
actuator. The
fast switching device includes a
circuit breaker on-off state acquisition module, a
voltage acquisition module, a current acquisition module, a
microcontroller, and a communication module. The circuit breaker on-off state acquisition module is used for acquiring the on-off state of the circuit breaker. The
voltage acquisition module and the current acquisition module are used for acquiring the
voltage and current values of a line respectively.
