Dry type transformer It has a certain degree of insulation. Dry type transformer The insulation performance is Dry type transformer One of the important properties. The insulation performance of dry type transformer is to be tested, but it is also necessary to pay attention to the relevant cycle when testing. What is the specific inspection cycle? Or do you want to know more about the Xiaobian of the dry type transformer factory?
(1) dry type transformers will undergo 1 checks in 2~3 months after commissioning, and will be checked 1 times a year.
(2) check whether the instrument and protective device of dry type transformer, pointer thermometer and so on are normal.
(3) check whether there is any dust, foreign matter blockage, rust or corrosion in the wind tunnel of dry type transformer.
(4) check whether there is any dust accumulation, whether there are cracks, discoloration, discharge and so on, and whether the insulation resistance is normal.
(5) check whether the winding compacting device is loose.
(6) check whether the contact points of ZD switch are overheated, tarnishing or corrosion.
(7) check whether the cooling device of dry type transformer includes motor and fan bearing.
The above is the main introduction of the insulation performance cycle of dry type transformers. We can detect dry transformers according to this cycle. If you have other questions, please contact our technicians.
