Problems solved by technology
[0005] The energy storage of aluminum electrolytic capacitors is low, and as time goes by, the capacity of the capacitor decays with time, the leakage increases, and the impedance becomes larger, which will affect the speed of the phase-controlled permanent magnet circuit breaker, that is, affect the closing and opening The life of the aluminum electrolytic capacitor and the working environment are limited; the voltage drops rapidly during the discharge process of the aluminum electrolytic capacitor, and the terminal voltage changes quickly, which is not conducive to the feedback control of closing and opening, which will increase the difficulty and technology of feedback control implementation Require
Many disadvantages of the above aluminum electrolytic capacitors will affect the stability of closing and opening time of the phase-controlled permanent magnet circuit breaker and the switching speed of closing and opening

The invention relates to a permanent magnet switch supercapacitor operation box. A step-down power converter is adopted for charging a supercapacitor module. Step-up conversion is performed in the supercapacitor module for output to a control module through a step-up power converter, so that the switching-on or switching-off time and switching speed of a phase-controlled permanent magnet circuit breaker can be controlled by the control module according to the magnitude of received voltage. The supercapacitor module is adopted, supercapacitors are abundant in stored energy and high in energy density, and the capacity changes a little along with time, so that influence on the switching-on and switching-off time of the phase-controlled permanent magnet circuit breaker is almost avoided, and the unfavorable influence of fluctuation of the switching-off and switching-on time is avoided.
Description
technical field [0001] The invention relates to a permanent magnet switch control method, in particular to a permanent magnet switch supercapacitor operation box with high power, fast energy storage, energy release and long cycle life.
