The transparent pipe of upper end opening, the one end and maintenance nozzle for overhauling tube opening are detachably connected, and the other end is plugged to oil tank of transformer
Bottom, the maintenance tube end plugged to oil tank of transformer bottom are not contacted with oil tank bottom；It is provided on the fuel tank top cover multiple
Nozzle is overhauled, is inserted with transparent maintenance pipe in each maintenance nozzle；It include two Turbidity measurement pipes, institute in multiple maintenance pipes
State and be provided with photoelectric detection system in Turbidity measurement pipe, photoelectric detection system includes photoelectric tube and sensor, the photoelectric tube and
Photoelectric sensor is separately positioned in two Turbidity measurement pipes, and the direction of illumination of photoelectric tube is towards the direction of photoelectric sensor；Into
One step, the photoelectric tube and photoelectric sensor that two Turbidity measurement pipe settings are arranged in fuel tank center, Turbidity measurement pipe are all provided with
It sets in the bottom of Turbidity measurement pipe；Further, multiple iron cores are provided in the fuel tank, the Turbidity measurement pipe is arranged at it
In two iron cores intermediate position, multiple transparent maintenance pipes are provided between the side wall and iron core of the fuel tank.
The positive advantageous effects of the utility model are: by the oil tank for oil immersion type transformer of box-type substation
Transparent maintenance pipe is set, fiberoptic visualization equipment can be utilized to box house component when needing to detect fuel tank internal
It is observed to search trouble location, maintenance pipe is detachably connected after being polluted outside maintenance pipe by oil body with fuel tank top cover
It restores to the original state after extraction maintenance pipe cleaning, and overhauls the former sealing structure that pipe does not destroy fuel tank, transformer station high-voltage side bus is not caused
Any influence；It overhauls and Turbidity measurement pipe is set in pipe, detected using turbidity of the electrooptical device to oil, keep oil detection real-time
Can survey, the missing inspection and detection when avoiding artificial detection not in time the case where, can find oil body quality problems in time, prevent fire
Accident occurs.
