Description

Technical Field

[0001] This utility model relates to the field of power supply device technology, and in particular to a power supply device for testing an energy storage shunt trip module. Background Technology

[0002] In existing technology, combiner boxes in photovoltaic (PV) power generation systems are wiring devices that ensure the orderly connection of PV modules and the function of current collection. This device ensures easy circuit disconnection during PV system maintenance and inspection, and minimizes the scope of power outages when a PV system malfunctions. The combiner box contains an energy storage shunt trip module that controls the disconnection of the combiner box's circuit breaker. During incoming quality control (IQC, controlling the quality of externally sourced products), the energy storage shunt trip module needs to be inspected. In practical applications, the combiner box receives DC 1500V power. During inspection, to save energy, the combiner box cannot be directly energized. Power is supplied to the energy storage shunt trip module via a DC 1500V power conversion (the combiner box has a switching power supply). Therefore, the inspection personnel need a dedicated AC 220V (mains) to DC 5V converter to power the energy storage shunt trip module. This device can... The current supply is a variable power supply or other type of switching power supply. Using a dedicated variable power supply is too expensive, while using other types of switching power supplies without structural components and simply connecting them with wiring harnesses poses a risk of the harnesses coming loose and creating a safety hazard. Furthermore, a batch of combiner boxes contains approximately 300 units, and each energy storage shunt trip module needs to be charged for 5 minutes before testing. Testing each energy storage shunt trip module in the combiner box individually using a variable power supply or other type of switching power supply is extremely time-consuming and inefficient. Therefore, this paper proposes a power supply device for testing energy storage shunt trip modules to solve the problems existing in the prior art. Utility Model Content
