Zusammenfassung: | The utility model discloses a ground complete set charging device used for a super-capacitor energy storage type tramcar. The ground complete set charging device comprises a breaker QF and at least two rapid charging units (1) which are connected in parallel, each rapid charging unit (1) comprises a DC isolation switch unit (11), a current transformer unit (12) and a networking isolation switch unit (13) which are sequentially connected together, the networking isolation switch unit (13) is used for supplying power supply output to the super-capacitor energy storage type tramcar, a positive input terminal of the DC isolation switch unit (11) is connected to a positive bus of a city rail traction network through the breaker QF, and a negative input terminal of the DC isolation switch unit (11) is connected to a negative bus of the city rail traction network. According to the ground complete set charging device used for the super-capacitor energy storage type tramcar, a present 1500 V or 750 V DC city rail traction network can be used, the super-capacitor energy storage type tramcar can be safely and rapidly charged with high power and a heavy current, the round complete set charging device is simpler in structure, repeated construction can be avoided, the implementation cost is low, and the management difficulty is low. |
