Introduction to several maintenance methods of Dongguan Power Transformer
Dongguan Juke Industrial Development Co., Ltd. introduces several maintenance methods for Power Transformers:
First: Regarding the main transformer of the 6~10kv workshop substation, the overcurrent maintenance with time limit is usually installed. If the overcurrent maintenance action time is greater than 0.5~0.7s, the current quick-disconnect maintenance should also be installed.
Second: Gas maintenance: Oil-immersed transformers with a capacity of 800kv.A and above should be equipped with gas maintenance as the main maintenance of the internal defects of the transformer tank and the oil level landing.
Third: current quick-break maintenance: in conjunction with gas maintenance, it can quickly remove the various shortcomings of the high-voltage side of the transformer and its internals, all of which are the main maintenance of the transformer.
Fourth: Overcurrent maintenance: It is to prevent the external short circuit of the transformer, the overcurrent caused and the backup maintenance as the main maintenance of the transformer, and the relay maintenance equipment installed.
Fifth: temperature maintenance: as a transformer oil temperature rise and cooling system, poor maintenance equipment.
Sixth: Single-phase grounding maintenance: It consists of a zero-sequence current transformer and a current relay connected to it. Maintenance as a disadvantage of single-phase grounding on the high-voltage side of the transformer.
