What Causes The Inverter Control Board To Burn Frequently?
Whether it is a large manufacturing factory in the automated production line or the common malls, residential buildings, etc. in life, the use of inverter is inseparable. Many devices in life use inverters, so what causes the inverter control board to be so easy Burning burn, resulting in the inability to operate in all aspects.
What is the reason for the failure of the inverter control board?
1. The interference of a strong current causes the inverter control board to fail
The interference and breakdown of strong current are fatal for converters. Because the power control circuit of the workshop is particularly strong, if the installation personnel put the power supply and inverter cabinets together for the convenience of management, the current generated by the rolling instantly is particularly large. This greatly increases the possibility of transformer suffering from strong electricity interference, which may cause the inverter control board to burn instantly.
2. Strike in strong electricity
The inverter was not installed well, and the corrosive gas entered. When the circuit breaker at the front of the inverter causes a trip due to special reasons, the high -power motor generates voltage action due to inertia. Because the strong electric cable and the control cable do not separate, it will generate high voltage on the control cable and burn the inverter!
3. Environmental factors cause the inverter control board to fail
The inverter itself is a heating body that needs to reduce the accumulation of heat through the cooling of air or water, so as to achieve the effect of heat dissipation. However The heat dissipation load, so that the inverter control board is prone to damage due to excessive temperature, or the internal filtering strong electric module of the inverter is damaged, causing the strong current to pass through the control board directly, resulting in failure.
4. Servo motor recovery causes the inverter control board to burn
When the servo motor is decelerated by the inverter, the motor will continue to run due to inertia because the brake unit of the motor does not stop or decelerates immediately. This is the regeneration current generated by the motor. The inverter will be returned, resulting in overvoltage failure, because some converters are not well designed in the servo motor. A reasonable circuit is generated, and the circuit filter of the inverter is also very fragile, causing the control board to fail due to a strong current circuit.
As a professional electronic manufacturing service(EMS) provider, TECOO, in order to reduce this kind of failure, considers most of the possibility of faults during design and manufacturing, and solves it, so that the service life of the inverter control board becomes longer.
