First, the common fault of the inverter : The company was founded in December 1995 with a registered capital of 300 million yuan. It is a private enterprise integrating R&D, production and sales of labor protection products. The company has a professional R&D team, standardized production lines and quality testing facilities. The company produces and operates more than 1,000 products, which can meet the all-round needs of labor protection "from head to toe".

In the past, transistor inverters mainly had the following disadvantages: easy to trip, not easy to restart, and low overload capability. Due to the rapid development of IGBT and CPU, the inverter has improved the self-diagnosis and fault prevention functions, which greatly improves the reliability of the inverter.
Second, the preventive measures for common faults of the inverter :
1. If the "automatic torque compensation function of the whole field" in the vector control inverter is used, the cause of failure such as "initial torque shortage" and "decreased output due to environmental conditions" will be well overcome. This function uses the high-speed calculation of the microcomputer inside the inverter to calculate the torque required at the current time, and quickly corrects and compensates the output voltage to offset the change in the output torque of the inverter caused by changes in external conditions.
2. The software development of the inverter is more perfect. Various fault prevention measures are set in the inverter beforehand, and the fault can still be continued after the fault is resolved.
1) The motor is restarted during free parking.
2) Automatic reset for internal faults and continuous operation.
3) When the load torque is too large, the running curve can be automatically adjusted to avoid trip protection.
4) It is possible to detect abnormal torque of the mechanical system.
The company is located in Dongying City, the central city of the Yellow River Delta, where the Yellow River enters the sea, where the grandson was born, and the Shengli Oilfield rises here. The two national strategies of [Yellow and Blue", the cooperative development of the Bohai Rim region and the coordinated development strategy of Beijing, Tianjin and Hebei are implemented in Dongying. Superior environmental advantages. Since its establishment, the company has always adhered to the company tenet of "people-oriented, sincere service", vigorously promoted the "Red Star" spirit, and earnestly fulfilled the mission of "growing together with employees, progressing with the times, seeking well-being for the society, and contributing to the country", Actively act and seek progress while maintaining stability. The company's products serve many fields, and the products are sold to both domestic and international markets. The company has successively become the director unit of the Occupational Health Protection Products Committee of China Textile Business Association, the member unit of China Labor Protection Products Alliance, the member unit of Shandong Labor Protection Products Industry Association, and the top 50 enterprises in the national labor protection industry; Anbel brand has become the labor protection products industry in Shandong Province. Association recommended brand.
