AI Technical Summary
Traditional transformer oil sampling methods are inefficient and result in significant oil waste during the sampling process. Furthermore, contact between operators and the oil may introduce contaminants, affecting the accuracy of the tests.
Design a transformer oil sampling device, including a tank, a sampling pump, a delivery pipe and a sampling cylinder assembly, to achieve automatic sampling. The sampling pump and delivery pipe draw oil into the sampling chamber, the piston controls the volume of the sampling chamber, and combined with a waste oil recovery mechanism and a filter assembly, the device achieves automatic oil washing and recovery.
This improved sampling efficiency, reduced oil waste, lowered the chance of oil sample contamination, and ensured the accuracy of oil sample testing.
