The stable and reliable operation of industrial equipment requires a stable energy supply, namely high-quality power supply. The current power quality is seriously affected and deteriorating, which has a great impact on the safe use of industrial equipment.
The main impacts of power supply are as follows:
a. Overvoltage: It can cause overvoltage alarms in the CNC system, accelerate component aging, and even damage.
b. Undervoltage: If the voltage is too low, the CNC system will trigger an undervoltage alarm, causing the CNC system to crash or restart and resulting in the loss of system parameters.
c. Voltage fluctuations: can cause the motor to run unevenly; Data loss; Relays and contactors shake and malfunction.
d. Surge impact: It can easily cause damage to CNC systems or servo drive components, leading to insulation breakdown of electrical equipment; At the same time, it is easy to cause system crashes and data errors.
e. Harmonic interference: The harmonic currents generated by nonlinear loads can affect multiple working processes of the CNC system, causing system crashes, resets, loss of data parameters, communication failures, and false alarms.
1. Based on the impact of the above power grid quality defects on industrial equipment, a specialized voltage regulator power supply for CNC machine tools has been developed to provide high-quality power supply for industrial equipment through the following aspects.
2. Maintain a precision output of ± 1% when the grid voltage fluctuates within ± 20%, to avoid the impact of high, low, and voltage fluctuations on the machine tool.
3. Reduce the impact of harmonics on the machine tool through filtering devices.
4. Reduce the impact of surge impact through anti surge devices
