A sampling tool for substation oil-filled equipment

Abstract

The invention discloses a sampling tool for transformer substation oil charge equipment. The front end of the sampling tool is of a hollow cylindrical structure, and the back end of the sampling tool is provided with an L-shaped flow guide tube; the cross section of the flow guide tube is circular, an upper inlet of the L-shaped flow guide tube is connected with the back end bottom of the hollow cylindrical structure, and a lower outlet of the L-shaped flow guide tube is connected with a sampling bottle; the hollow cylindrical structure comprises an adsorption region at the front end and a buffer region at the back end, a port of the adsorption region serves as an oil discharge valve joint which is of an inclined opening structure from left upper part to right lower part, and the periphery of the oil discharge valve joint is uniformly provided with a circle of magnets; the upper part of the buffer region is provided with an opening close to the oil discharge valve joint, and an observation window covers the upper part of the opening; the L-shaped flow guide tube comprises an upper vertical tube and a lower horizontal tube, and a sampling bottle joint is arranged at the tail end of the horizontal tube and is connected with the sampling bottle.

Description

technical field [0001] The invention relates to a substation auxiliary tool, in particular to a tool for taking oil samples in oil-filled equipment. Background technique [0002] Transformer oil-filled equipment needs frequent sampling and analysis to monitor the acidity, particle size, viscosity, sulfur and copper ion content of the oil, etc. Usually, when sampling the oil-filled equipment, it is enough to adjust the oil outlet valve switch of the oil-filled equipment To control the flow of oil into the sampling bottle at an appropriate speed, try to avoid long-term exposure of the oil sample to the air, and avoid artificial oil leakage caused by improper operation during sampling, which will further cause pollution to the environment of the substation and other equipment. The size of the valve switch should be properly controlled during sampling. If the oil discharge speed is too slow, not only the work efficiency will be low, but also the oil sample will be exposed to the...
