Anti interference of plasma power supply
 
The main interference source of the plasma numerical control system is the power supply part. It usually adopts the high frequency ignition device is used to ignite the arc, high frequency transformer secondary side voltage up to 3000 - 6000V, pulse frequency of 100 Hz, radiated interference and the grid pollution (interference) are very strong, and high current AC / DC contactors and relays off fault on the grid will cause surge. Usually the plasma cutting machine arc caused by the computer's internal chaos, can not be normal cutting, the first CNC cutting machine and even require the user to start arc and then start the computer, running the CNC system program. This not only makes the complicated operation, the computer is not fully utilized, but also seriously affect the life of the computer, so the suppression of plasma power interference, reduce the pollution to the power network is the primary problem, specific measures:
 
(1) is to increase the high frequency arc shield, reduce high-frequency radiation;
 
(2) improvement of control system of plasma power.
 
Plasma cutting machine of the control power supply of 220V directly quoted from the grid voltage, / arc arc line directly from the cutting machine leads to numerical control electrical cabinet, and during CNC power system together, so that the plasma / arc caused by the high frequency interference and electromagnetic interference caused by high current directly on into the grid. Measures the voltage of 220V control line increased isolation transformer. At the same time / destroy arc control signal through the relay isolation is relative weak AC 24V control line into the numerical control electrical cabinet.
