Low-voltage transformer bushing insulators: Functions, types and importance

In the power system, the transformer is one of the key equipment, responsible for voltage conversion and power transmission. As an important component of the transformer, the function, type, and importance of the low-voltage transformer bushing insulators can not be ignored.

First, the role of low-voltage power transformer insulator

Support and fixing: Low-voltage transformer bushing insulators mainly support and fix the role of the transformer winding, to ensure that the winding in the transformer inside the position is stable.

Insulation: The insulator can effectively isolate the transformer winding and other metal parts such as the transformer oil tank, prevent the leakage of current, and ensure the safe operation of the system.

Moisture-proof and anti-fouling: the insulator has a certain moisture-proof and anti-fouling ability, which can protect the normal operation of the transformer and prevent failure caused by humidity or pollution.

Two, the type of low-voltage transformer bushing insulators

Classification by material: Common low-voltage transformer bushing insulators are ceramic insulators, glass insulators, and composite insulators.

Classification by use: According to different use environments and needs, low-voltage power transformer insulators can be divided into indoor type and outdoor type, high and low voltage type.

Third, the importance of low-voltage transformer bushing insulators 

Safety guarantee: The good performance of low-voltage transformer insulators can ensure the normal operation of the transformer and prevent safety accidents caused by winding short circuits and leakage.

Stability guarantee: the quality of the insulator directly affects the stability and life of the transformer. High-quality insulators can ensure the long-term reliable operation of the transformer and reduce the failure rate.

Maintenance and testing: For installed low-voltage power transformer insulators, regular maintenance and testing should be carried out to discover and deal with potential problems in time to ensure the safe operation of the system.

Forth. Conclusion

Low-voltage power transformer insulators play a vital role in the power system. To ensure the normal operation of the power system, we must pay enough attention to the low-voltage power transformer insulator, select the appropriate material and type, and carry out regular maintenance and testing. Only in this way can we give full play to the role of low-voltage power transformer insulators and provide a strong guarantee for the development of electric power.
