Shore electricity power supply
Quay ship high power frequency conversion power supply is
especially used on ship, shore quay, where the environment is very
bad, with high temperature, high humid, high erosive, and large
load. All the PCB boards adopt coat solidification process, sine
wave filter and output transformer which adopts whole vacuum
dipping isolation lacquer and sprays high temperature protection
lacquer, with high isolation degree and protection ability,
completely accords with Chinese ship classification society CCS
attestation standard. It is widely used on ship, ship manufacture
and repairing factory, ocean making hole flat roof and shore quay,
where need to change 50Hz industry electricity to 60Hz high quality
stable frequency and voltage power supply, and also for the
equipments on the ship. Performance Index: Rating input voltage:
Input power supply is 380V/50HZ factory electricity.(The AC voltage
is allowed to range from 323V to 528V ) Rating output voltage: we
can supply many single phase/triphase grades according to the
requirement of the clients. Rating output frequency: 60HZ50HZ(can
change freely) or400Hz The precision and output voltage stability:
The allowance of the output frequency0.01Hz, stability0.01when the
load is changing from 0 to 100, the output frequency doesnt change.
The stability of the output voltage: static state1, dynamic3 The
instant change when the 50 load suddenly plus/reduce5, and will
come back to the rating output voltage. Over load ability of the
frequency conversion power supply 150% 10 minutes, 200% 10s The
total harmonic wave distortion of the output voltage: THD1.2~2.8%
The dampproof and dustproff grade: IP54 Protection function:
complete protection for over voltage, lack of voltage, over
current, short circuit, lack of phase, overheat of the inverter and
the transformer.(the protection valve can be set freely)according
to the electricity load of different ships, In order to control the
electricity loadIt will make an alarm when the output load capacity
is up to any number had been set
