On-ball power supply and distribution device for mooring balloon

Abstract

The invention discloses an on-ball power supply and distribution device for mooring a balloon. An input end of the device is connected with a high-voltage cable, and the device comprises a ball powersupply and distribution unit, a load power supply and distribution unit and a data acquisition and processing unit; the ball power supply and distribution unit is connected with ball equipment, the load power supply and distribution unit is connected with load equipment, and the data acquisition and processing unit is connected with the ball power supply and distribution unit and the load power supply and distribution unit separately. The device has the advantages that by adopting power electronic transformation equipment and solid-state power distribution equipment based on power electronic technologies, the equipment weight is remarkably reduced; the two sets of power distribution equipment are designed to supply power to the ball equipment and the load equipment respectively, and the power supply reliability is improved; through the integrated design of power transformation, power distribution and communication, the intermediate conversion links of a power distribution system are reduced, and connection ports are simplified.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution devices, in particular to an on-ball power supply and distribution device for mooring balloons. Background technique [0002] At present, the power supply and distribution system of tethered balloon products on the market generally adopts high-voltage transmission. The electric energy of the power supply network is raised to thousands of volts of high-voltage alternating current by the power frequency or intermediate frequency step-up transformer on the ground, and then transmitted to the ball through a long-distance tethered power supply cable; It is mainly composed of a step-down unit, a power supply unit, an emergency power supply unit and a power distribution unit, and each part is an independent part; among them, the step-down unit is a power frequency or intermediate frequency step-down transformer, and the power supply unit converts the low-voltage power output from th...

Problems solved by technology

If the load equipment fails to be dealt with in time, it will cause damage to the spherical equipment and affect the normal operation of the aerostat;

[0006] 3) Each component unit of the on-ball power supply part is independently designed with a cabinet, which increases the volume and weight of the on-ball power supply subsystem; the number of interfaces between the cabinets is large, which increases the complexity of the system, and the maintenance and manufacturing costs are high; There are many intermediate conversion links in the power supply and distribution system, which reduces the reliability of the system
