Problems solved by technology
In addition, particulate impurities may also cause partial discharge or act as a catalyst to cause oil deterioration, thereby affecting the safe operation of the transformer
[0003] At present, most of the particle size detection does not have a special sampling protection device, and the oil samples obtained are easily polluted by the external environment (such as wind, sand, dust, etc.), resulting in the sample taken out may not be able to truly and accurately reflect the actual particles of the oil product degree of pollution

The invention relates to a field sampling protecting device for transformer oil particle detection. The device comprises a shell with an accommodating cavity and is characterized in that the lateral side of the shell is provided with a sample feed inlet and a handle, the top of the shell is sealed, the bottom of the shell is provided with an opening, a sampling device can extend into the shell through the bottom opening, and a transformer oil sample flows into the sampling device through the sample feed inlet. The field sampling protecting device has the advantages that during sampling, the sampling device is placed into the shell through the bottom opening, the oil sample flows into the sampling device through the sample feed inlet, the splashing oil sample during the sampling is received by the shell, the splashing oil sample is accumulated in the sampling protecting device, and sand blown by the wind and dust can be isolated.
Description
technical field [0001] The invention relates to an on-site sampling protection device for detecting transformer oil particles. Background technique [0002] With the increase of UHV transformer equipment in power grid construction, it is very necessary to carry out the detection of particle pollution index in transformer oil. Particle pollution in insulating oil affects the electrical properties of insulating oil. A large number of suspended particles will be arranged regularly under the action of an electric field to form conductive bridges, which will significantly reduce the breakdown voltage of the oil. In addition, particulate impurities may also cause partial discharge or act as a catalyst to cause oil deterioration, thereby affecting the safe operation of the transformer. [0003] At present, most of the particle size detection does not have a special sampling protection device, and the obtained oil samples are easily polluted by the external environment (such as win...
