Description
Technical field
The invention belongs to captive balloon power supply and distribution engineering device technique fields, and in particular to a kind of high straightening for captive balloon
Flow electrical power trans mission/distribution system.
Background technology
At present on the market in captive balloon product electrical power trans mission/distribution system using high-voltage alternating scheme, i.e., using power frequency or
Medium frequency alternating current is transmitted：Power supply network electric energy by ground power frequency or intermediate frequency step-up transformer will exchange electric pump rise to it is thousands of
After the High Level AC Voltage of volt, the power supply hawser that is tethered at through long-distance is transmitted on ball, power frequency or the intermediate frequency decompression carried on ball
Transformer converts electric energy into again is supplied to sphere equipment and loading device for low pressure power frequency, voltage of intermediate frequency.
There are following 3 drawbacks in captive balloon use occasion for above-mentioned power transmission and distribution scheme：
1) using exchange long distance powedr transmission, one side electrical equipment can additionally generate the demand of reactive power, on the other hand
Long range is tethered at power supply hawser and can also generate the loss of reactive power, in the case of using intermediate frequency transmission of electricity on tether cable
Reactive power loss bigger, can account for the 50% of total losses, bring the pressure drop of bigger therewith, reduce the transmission of electricity for being tethered at power supply hawser
Ability；
2) power frequency or intermediate frequency step-down transformer are configured on ball can dramatically increase the weight of power subsystem equipment, and weight is about
40% of power subsystem total weight on ball is accounted for, the weight of captive balloon equipment of itself is the core of relationship captive balloon system scale
Heart factor, if the weight of step-down transformer in transmission of electricity link can be reduced, performance, cost performance to promoting captive balloon system etc.
Aspect has important meaning；
