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
(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.
(3) other wiring anti-interference measures
Main transformer primary side and secondary side increased RC
absorption circuit and a varistor, the contactor and the relay coil
is connected in parallel with resistance capacitance circuit, the
DC part set a high frequency bypass capacitor, the purpose of all
these measures is suppressing the interference source and reduce
the pollution to the grid voltage.
