Embodiment 1
[0033] figure 1 It is a schematic diagram of a mobile charging system for an energy storage rail transit vehicle provided in an embodiment of the present application.
[0034] Such as figure 1 As shown, the mobile charging system provided by this embodiment includes a power supply device 10 , a conductive rail 20 and a current collector 30 .
[0035] The power supply device 10 is arranged at the station, and its power output terminal is connected to the conductor rail 20 for outputting electric energy to the conductor rail 20 by using the mains power.
[0036] The conductive rail 20 is arranged at the station, and is arranged parallel to the track 200 of the station. The conductive rail 20 can be arranged above the rail 200 or beside the rail 200, both of which are within the protection scope of the present application. For the convenience of description, this embodiment only illustrates the case where the conductive rail is arranged above the rail 20 .
[0037] The curren...
Embodiment 2
[0041] The mobile charging system provided in the previous embodiment can start charging when the energy storage type rail transit vehicle enters the station, and stop charging after leaving the station, that is, the current receiver is out of contact with the conductive rail. However, due to the large charging current, when the current receiver is separated from the conductive rail, arcing will occur due to the large current, which may cause damage to the compartment. In order to avoid the occurrence of arcing, this embodiment is proposed.
[0042] In this embodiment, an outbound detection device and a switching circuit are added on the basis of the previous embodiment.
[0043] The outbound detection device is arranged at the outbound end of the conductive rail, and is used to generate a vehicle outbound signal when the energy storage type rail transit vehicle leaves the station.
[0044] The switching circuit is set in the power supply device, which is used to control the p...
Embodiment 3
[0048] Generally speaking, only when the energy storage type rail transit vehicle is at the station, it is used to supply power to the conductor rail. If the power supply is uninterrupted, it will cause a certain amount of power loss. In order to avoid this power loss, if the power supply device always outputs power to the conductor rail, Then it is best to supply power to the conductor rail after the energy storage type rail transit device enters the station, and this embodiment is proposed for this reason.
[0049] In this embodiment, on the basis of the previous embodiment, a vehicle entry detection device is added. The vehicle entry detection device is used to output the vehicle entry when the current receiver of the energy storage type rail transit vehicle is at the entry end of the conductive rail. Signal. The switching device is also used to control the power supply device to output electric energy to the conductor rail according to the vehicle entering the station sign...
