The present invention discloses a high-voltage direct current distribution system for a captive balloon. The system comprises an aboveground power supply portion and an on-balloon power supply and distribution portion; the aboveground power supply portion comprises an alternating current supply network which is connected with an AC / DC rectifier; the aboveground power supply portion and the on-balloon power supply and distribution portion are connected through a high-voltage direct current cable, and an input end of the high-voltage direct current cable is connected with an output end of the AC / DC rectifier; the on-balloon power supply and distribution portion is configured to perform power supply and distribution for an on-balloon device, wherein the on-balloon device comprises an on-balloon DC / DC converter set, a load converter set and an on-balloon integrated distribution unit; and an output end of the on-balloon integrated distribution unit is connected with a balloon device and a load device, a direct current bus of the balloon device is distributed to the balloon device through the on-balloon integrated distribution unit, and electric energy output by the load converter set isdistributed to the load device through the on-balloon integrated distribution unit. The high-voltage direct current distribution system for the captive balloon can effectively improve the transmission capability of the high-voltage cable, reduce weight of the on-balloon power supply and distribution portion, simplify a power supply and distribution device and improve the system reliability.
Description
technical field [0001] The invention belongs to the technical field of power supply and distribution devices for tethered balloons, and in particular relates to a high-voltage direct current power transmission and distribution system for tethered balloons. Background technique [0002] At present, the power transmission and distribution system of tethered balloon products on the market adopts a high-voltage AC scheme, that is, power frequency or intermediate frequency AC power is used for transmission: the power of the power supply network passes through the power frequency or intermediate frequency step-up transformer on the ground to raise the AC power pump to thousands of volts After the high-voltage alternating current is transmitted to the ball through a long-distance tethered supply cable, the power frequency or intermediate frequency step-down transformer mounted on the ball converts the electric energy into low-voltage power frequency and intermediate frequency voltag...
