AI Technical Summary
Existing technologies cannot detect faults in the early stages of partial discharge in converter transformers, leading to the inability to clear faults in a timely manner and potentially escalating into serious accidents.
An early protection system and method for converter transformers based on dissolved gas monitoring in oil is developed. This system utilizes multiple oil samplers, oil mixing devices, online monitoring devices, and controllers to monitor the gas concentration, especially acetylene concentration, in oil samples within the converter transformer in real time, enabling early fault detection and closure of DC valve groups.
This technology enables early detection and timely handling of faults in converter transformers with partial discharge, preventing faults from developing into accidents, improving the accuracy and safety of monitoring, and reducing personal risks and costs.
