Widely used in electrical manufacturing departments, power operation departments, research institutions, and universities Equipped with automatic volt
Product details
MEWJF-300kW
No partial discharge variable frequency test power supply
characteristic:
The non partial discharge variable frequency test power supply has the ability to resist electric field interference. Under strong electric field interference, the measurement accuracy and control protection meet the requirements. It has good magnetic shielding, and the components and leads are shielded with high magnetic conductivity materials, without spatial radiation.
System functions:
a) The variable frequency power supply adopts a linear power amplifier circuit, with intact sine wave output and low waveform distortion
b) Equipped with automatic voltage stability adjustment function
c) Safe and reliable. This device integrates various protections, including discharge breakdown protection, overvoltage and overcurrent setting protection, output short circuit protection, startup zero position protection, bridge arm amplification circuit protection, power curve protection, etc. When any type of protection occurs, the device immediately blocks the test voltage output, cuts off the main circuit power supply, and ensures the safety of the test personnel, test subjects, and test system
d) Using fiber optic transmission to transmit high-voltage measurement signals, completely isolating high-voltage and low-voltage circuits
e) Automatic/manual control modes
f) 320 * 240 dot LCD display and multiple rotating mice provide a friendly human-machine interface, with easy and fast operation and wiring, truly achieving "at a glance"
g) Synchronized voltage, current, and frequency display
h) The output frequency is continuously adjustable within the range of 20-300Hz
i) Continuous adjustable output voltage within the range of 0-350V
j) Capable of resonant withstand voltage test
k) Equipped with automatic resonance frequency search function, multiple automatic sweep frequency bands can be set
l) Small size, light weight, flexible handling, very suitable for on-site use.
System display function:
1) Equipped with a large screen display, it can indicate: output voltage, output current, frequency, ambient temperature, outlet air temperature, output voltage waveform of variable frequency power supply, date and time, countdown time, fault information, etc;
2) It has the function of setting test parameters such as test voltage and time;
Other features of the product:
a) There is no oil leakage in the oil filling equipment in the device.
b) All metal shells in the device have undergone rust prevention and anti-corrosion treatment, with uniform and beautiful coatings. The main components have stainless steel nameplates and terminal markings. The main components such as the variable frequency power cabinet and excitation transformer are equipped with dust and rain covers. The power control box is equipped with a dedicated shockproof aluminum alloy box. The equipment structure is sturdy and reliable, and can work normally under outdoor and sunny conditions. The protection level of the inverter power supply casing meets the requirements of IP54, and the protection level of other equipment casings meets the requirements of IP66.
