Embodiment Construction
[0033] The technical scheme of the present invention will be further described in detail in conjunction with the accompanying drawings.
[0034] The constant current underwater power supply network of submarine observation network such as figure 1 As shown, multiple underwater power sources are distributed, and each underwater power source is connected by a long-distance submarine cable. The overall power is high, and there is a 10,000-volt voltage to ground on the underwater power source and the cable near the shore PFE. .
[0035] A kind of underwater power source suitable for constant current power supply type submarine observation network of the present invention is such as figure 2 As shown, it consists of two independent DC conversion cabins and a balanced load cabin. The DC conversion cabin is as follows image 3 As shown, it includes an overvoltage and overcurrent protection circuit, a main power conversion circuit and a constant power circuit to complete the power ...
