ENERGY STORAGE VALVE SUBMODULE, ENERGY STORAGE VALVE, AND ENERGY STORAGE STATION

Abstract

This disclosure relates to the field of power electronics technology and provides an energy storage valve submodule, an energy storage valve, and an energy storage station. In the energy storage valve submodule, a power module can disconnect an electrical connection from an energy storage module through a switch module, forming electrical isolation, thereby achieving the electrical disconnection between the power module and the energy storage module. During maintenance of components other than the energy storage module in the energy storage valve, leakage current is prevented, ensuring the personal safety of maintenance personnel. Similarly, in the case of a non-severe fault on the energy storage module side of the energy storage valve, the switch module can be used to isolate the energy storage module from the system under the premise that the energy storage valve is locked, without affecting the safe operation of the entire system, effectively improving system availability.
