characteristics
Voltage transformation: A power transformer can convert high voltage electrical energy to low voltage, or vice versa. This voltage transformation capability enables long-distance transmission and distribution of electrical power.
Power transfer: Power transformers are capable of handling high power levels. They facilitate efficient power transfer within the electrical system by coupling the energy.
High conversion efficiency: Power transformers exhibit high conversion efficiency, typically exceeding 95%. This means that only a small amount of energy is lost during power transmission, ensuring the overall efficiency of the power system.
Good insulation performance: Power transformers provide insulation between different voltage levels, effectively preventing high voltages from damaging low voltage equipment. They possess excellent insulation properties and establish electrical isolation between the high voltage and low voltage sides, ensuring the safe operation of the system.
Strong stability: Power transformers are designed with high-quality insulation materials and structures to withstand harsh environmental conditions such as high temperature and humidity. They demonstrate good stability, enabling long-term operation with low failure rates.
Low maintenance cost: Power transformers typically have long service lives, resulting in relatively low maintenance costs. Proper operation and maintenance practices can extend the lifespan of power transformers and ensure their stable performance.
