1 Main circuit of high-power IGBT inverter power module and an important part of a drive circuit, high frequency switching transformer, the control part of the letter all integrated circuit adopts imported components, to ensure the reliability of the machine.
2 The work frequency of the circuit changes over load, through the phase locked circuit can realize stable frequency automatic tracking, locking, reduces the power device of main loop current and voltage stress, make its best working condition.
3 It has soft start function to prevent the current impact caused by power startup and the pollution of the power grid and the possible damage to the host.
4 With three-phase short of phase, fault phase protection, bridge arm straight short circuit protection, over current protection, over temperature protection, protection, unlocked inverter load corona shaft stalling protection, electrode holder open protection, load breakdown of fire protection.
5 Load corona shaft stalling protection, electrode open protection function can choose to use, the function is to prevent because of the broken film or other reasons make the rubber shaft caused a halt in plastic shaft in the same position for a long time discharge and breakdown plastic shaft.
