The invention provides a direct-current isolating switch integrated test system for energy storage. The integrated test system comprises a power supply subsystem, a current detection subsystem and a control subsystem; and the power supply subsystem comprises a storage battery pack, a first power supply switching power supply and a second power supply switching power supply, the input end of the first power supply switching power supply and the input end of the second power supply switching power supply are both connected with the output end of the storage battery pack, and the output end of the second power supply switching power supply is provided with a UPS. The integrated test system is simple in structure, easy to build and use, capable of being suitable for testing multiple functions of a direct-current disconnecting switch, capable of conducting performance testing on the direct-current disconnecting switches of different control voltage grades and fully verifying the performance states of the direct-current disconnecting switch under different conditions, high in testing efficiency and good in testing effect; and meanwhile, the test system can test multiple groups of direct-current disconnecting switches, so that the test and inspection efficiency of the direct-current disconnecting switches can be further improved.
Description
technical field [0001] The invention belongs to the field of DC isolation switch testing, in particular to an integrated testing system for a DC isolation switch used for energy storage. Background technique [0002] The DC isolation switch plays a key role in the energy storage system. When the storage system is abnormal or the grid side is abnormal, the controller needs to perform operations such as closing and opening the DC isolation switch to avoid damage to the entire system due to its fault. The testing of DC disconnect switches is particularly important. However, in the common inspection and testing method, it is necessary to build different tooling for different DC disconnect switches, which has the problems of cumbersome testing and low testing efficiency; the existing testing systems are generally complex in structure and have poor reliability. The test tool is more complicated to test; in particular, different test loops need to be built according to the current...
