Current transformer maintenance knowledge and importance
Oct 10, 2022| Regular maintenance of the current transformer can prolong the service life of the current transformer and ensure the reliability of the daily operation of the current transformer. And users need to know the knowledge about maintenance in order to better maintain the current transformer.
When maintaining current transformers, it is necessary to pay attention to whether the current transformer products have power generation or other abnormal phenomena during operation. However, if the general current transformer generates electricity, it is very likely that the current transformer is partially damaged, so the maintenance personnel need to remove and repair it in time.
In the maintenance work of the current transformer, it is necessary to check whether the temperature of the joint of the secondary circuit of the current transformer is normal, so as to prevent the temperature from being too high and cause damage to the components; it is also necessary to carefully check whether the current transformer in operation has abnormal noise or Odor, if there is peculiar smell or abnormality, it is very likely that the internal insulation of the current transformer is heated to produce peculiar smell and the vibration of the silicon steel sheet is not obvious, the sound is uneven, and a large noise is generated. The actual cause of the failure needs to be checked according to the situation on site Clear; it is also necessary to check whether the three-phase indicated value of the instrument exceeds the rated value, the three-phase indicated value should be within the allowable range, and overload operation is not allowed; it is also necessary to check the insulation of the current transformer to ensure good insulation performance; keep the current mutual inductance The quality of the disc is clean and free of cracks and discharges.
The maintenance personnel can put the current transformer into normal use only after the comprehensive maintenance and inspection of the current transformer. Users should pay attention to the maintenance of current transformers. If the current transformers are not maintained for a long time, the line damage will become more serious, and even explosion accidents will occur, which will threaten the life of personnel.
