quality product dispute situation:
According to the situation reported by the entrusting party and the information provided, the entrusting party signed an "Order Order" with a certain company (hereinafter referred to as the supplier) to purchase isolation cabinets, main cabinets, SVG reactive power compensation and other photovoltaic power station equipment. During the debugging process of the SVG reactive power compensation equipment involved in the case, the IGBT of the equipment burned out.
In order to further clarify the cause of the equipment damage, the client hopes to conduct a quality analysis on whether the "SVG equipment" involved has quality problems that caused it to burn.
quality analysis results: The
quality analysis expert group discussed the relevant information and on-site investigation and inspection of the "SVG equipment" involved and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions: The
involved SVG electrical cabinet complete machine and function The rate box has no physical evidence of overvoltage, overcurrent, or link failure bypass protection measures. Each power unit has physical evidence of low insulation resistance, which does not meet the requirements of relevant standards. When the SVG cabinet involved in the case was closed, it caused overvoltage of the IGBT, causing the insulation of the IGBT to be destroyed, causing a short circuit fault inside it, causing the IGBT to burn out.
