1. MAGNETIZING ELECTRICAL-ELECTRONIC EQUIPMENT 800V, 1200A

2. Repeating cycle rate of magnetizing : 3 sec
Application:
Magnetizing of neutral permanent magnetic material in the parts
Installed into the continuous working production line
Repeating cycle rate of magnetizing : 3 sec

3. Short description of operation:
- Input voltage: 3x400V AC , 50/60Hz
- This voltage is rectified by a three-phase bridge-diode
- The output voltage is modified and transformed into high frequency (20-30kHz)
- Capacitance of capacitor field: mF.
- Voltage of capacitors up to 800V DC
If the voltage of capacitors reaches the pre-adjusted value – managed by the operator with a potentiometer - it will be transferred to the magnetizing coil.
In the magnetizing coil is going to be generated a current (300 ÷ 1200A) and this current generates a magnetic field in the coil and the neutral magnetic material placed into the gap of this coil will be magnetized.

6. Magnetizing cycle showed by oscilloscope diagram:
Horizontal axis: time scale =0,025 sec/square
Vertical axis – green colour: voltage scale
capacitor field = V/square
Vertical axis – blue colour: magnetizing current:
A/square
The diagram shows:
-After switching on the thyristor SCR the voltage of capacitors decreases from 485V to 0V
within 0,028 sec
-Peek value of magnetizing current:: 875A.
-Peek value of magnetizing current grows up within 0,025 sec after switching on the thyristor SCR
The magnetizing current decreases within
approx. 0,2 sec to 0V.

7. Oscilloscope diagram in case of continuous working:
- In case of 684 V capacitor voltage it is possible to do magnetizing cycles approx. every 3 seconds.
- In case of lower voltage the magnetizing cycle rate could be increased.
