It is realized between transmission channel and transmitter between underwater sound basic matrix and transmitter waterborne often through towing cable, underwater connection box
Electrical interconnecting.Using traditional water tight junction box, it is used in parallel to be usually present multiple energy converters in terminal box, multiple groups energy converter structure
At a transmission channel equipment is emitted by certain all the way and carries out high voltage supply driving, once some or the appearance of several energy converters are short
Road, such as because watertight failure leak, infiltration, the moisture absorption, high pressure arcing cause electrical short, when high-pressure work, will cause corresponding hair
Penetrate machine damage, since transmission channel is few, some or several transmission channels do not work will cause basic matrix transmitting source level performance compared with
Big decline to bring non-scheduled maintenance, or even causes active probe task to fail, and influences high-power acoustics basic matrix and uses
Reliability.
