The method and whole process of taking oil sample of power transformer are as follows:
Kur ī gr ā Zone M.In order to promote the use of energy-saving transformers,Kur ī gr ā Zone MSCB dry type transformer model, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as 2012,Kur ī gr ā Zone MSubstation transformer, providing subsidies of 4-30 yuan / KVA for energy-saving transformers.
Difference between dry-type transformer and oil immersed transformer:

Causes of fire in power transformer
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore,Kur ī gr ā Zone M480v dry type transformer, the insulation compressive strength of power transformer shall be tested before installation and operation, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation and overload is not allowed in the whole process of operation.
The domestic transformer market is slow
Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.
Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.

quality standard.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.
Hand touch method for transformer inspection
Power transformers are used in all walks of life
Kur ī gr ā Zone M.Power transformers are used in all walks of life
After no-load test run is normal for 24h, it can be transferred to on-load operation and the load shall be gradually increased from 25%, 50% and 75% by grade.
The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
