Abstract
A chromatographic general test of the oil-filled box transforme of a photovoltaic power plant nationwide is conducted
the results are the total hydrocarbon hydrogen index which statistics
such as high failure rate has familial aggregation phenomenon
analyzing the fault type
partial discharge fault of high energy is larger for related issues from the perspectives of equipment construction operations
the reason analysis
proposed to increase partial discharge test before delivery to strengthen the construction process control corrective actions and preventive strategies such as targeted overhaul.It has certain reference significance for the operation and maintenance of such equipment.
