380V 22KW 30KW 37KW Variable Frequency Inverters For Submersible
Pump
1. Deceleration over excitation function
Accurate thermal simulation platform software ensures the
reliability of thermal simulation.
Each VFD500 inverter has undergone thermal simulation testing, and
only the physical prototype is developed within the scope of the
thermal simulation safety design requirements. After the actual
test, the thermal simulation results are very close to the physical
test results. In the limit test state, the thermal simulation can
replace the actual load simulation and an additional layer of
scientific thermal test.
2. Rigorous temperature rise test
The whole machine temperature rise test uses the most severe cyclic
overload test to meet the long-term reliable operation under
extreme load conditions.
Cyclic overload test: 1.5 times overload current for 1 minute,
ambient current for 4 minutes, and 1.5 times operation for 1 minute
at ambient temperature of 40°.
This continuous cycle operation, 1 cycle for 5 minutes, until the
system reaches the thermal equilibrium state, the whole machine is
within the thermal design safety range.
3. Complete protection
The whole series has output to ground short circuit protection,
over current protection, drive overload protection, motor overload
protection, drive over temperature protection, optional
PT100/PT1000 motor over temperature protection.
According to the type of fault, it can be set as fault free stop,
fault deceleration stop, fault continue to run, and facilitate the
on-site handling of emergency situations.
Adopting multiple high-quality three-proof paint to enhance the
environmental adaptability of the product. The three-proof paint
adopts the automatic spraying process to ensure the uniformity of
the thickness of the coating and the consistency of the batch.
