As a commonly used power control equipment in modern industrial fields, the stable operation of frequency converters is crucial for ensuring the continuity of production lines and the safety of equipment. 

However, due to various factors, the frequency converter may experience malfunctions during use.

Case background

MEGMEET frequency converter in a certain factory experienced a machine explosion/startup tripping fault. Causing the production line to be forced to shut down, affecting production efficiency.

Fault detection

After inspection by Zhonghaide engineers, it was found that the driver board was damaged, the rectifier inverter IGBT was damaged, and the bottom plate was burnt through.

On site service

Solution results

After communication between engineers and on-site technicians, a solution was provided and implemented in a timely manner, successfully restoring production on the production line and reducing losses 

caused by downtime maintenance.

proposal

After using the frequency converter for a period of time, there will be varying degrees of dust accumulation and aging corrosion inside the frequency converter, which will affect the operating temperature of 

the frequency converter, directly affecting the load capacity, failure rate, and service life of the frequency converter. Regular maintenance can greatly extend the service life of the equipment and reduce the 

losses caused by shutdown maintenance.
