Summer is the peak period of electricity use. At this time, it is a test of the transportation equipment in the store. Transformers, as an important part of transmission and distribution equipment, play a role in changing voltage and current and are of vital importance. Therefore, they are used very frequently. . Because of this, the probability of failure of transformers during the summer peak period has greatly increased, and the probability of failure has also increased. The following is a brief description of transformer repair methods and common failures.
What is a transformer
First understand the structure of the transformer, the transformer is composed of iron core, windings, sleeves and other components, while the sleeve plays a role in the insulation and fixing of the oil tank, while being exposed to the sun and the environment, its impact on the environment Very big.
Transformer common fault
The transformer is exposed to the outside for a long time, so a long period of rain washed on the surface of a layer of the sleeve is rusted by rain and dirt, resulting in reduced insulation properties, resulting in frequent tripping, but also rust the internal components of the transformer, directly Affects transformer life. There are two main reasons for the failure of casing seals: one is that due to lack of experience of maintenance personnel, the bolt fastening force is not enough; the second is due to super cycle operation or the quality problems of pads, aging of the pads, etc.; the structure of the casing itself is not Reasonable and flawed.
Transformer maintenance method
The solution is to regularly inspect and repair the transformer, clean up the garbage and rainwater on the enclosure, and ensure the cleanliness of the transformer. At the same time, the poor sealing of the inner casing of the transformer should be promptly replaced with a good quality rubber pad to keep the seal tightly tightened and fastened. Bolts, so that the casing no leakage, but also check the casing is overheating, if you can change the copper and aluminum transition to silver and copper contacts, thereby reducing the oxidation. It should also be noted that when the transformer is being overhauled, conductive paste should be applied on the contact surface in advance to reduce human-induced damage.
The above is the transformer repair method and the common faults of the transformer brought by Xiaobian. The transformer plays an important role in the power supply system. It is also very important for the periodical overhaul of the transformer. Therefore, the power company should regularly repair and maintain the transformer. Peak hours can greatly reduce the frequency of failures. I hope the above introduction can help everyone, if you want to know other related information, please continue to pay attention to this site, more exciting so stay tuned!

hard-faced wear-resistant steel plate is kind of steel plate, which adopted the international leading metal arc welding production technology, welded a certain thickness wear resisting alloy layer on the surface of common low carbon steel or low carbon low alloy steel . The product wear-resisting layer has high hardness, with good wear-resistant properties.
* HP100 (Low stress abrasive wear)
HP100 hard-faced wear-resistant steel plate is suitable for the low stress, little impact abrasive wear or fine particles, minimal energy and small incident Angle erosion wear condition.
