Wire and Cable Expo 2024 Insights: The Advantages of High-voltage Transmission and The Common Types of Accidents
Due to the uneven distribution of population and energy resources, some regions have a demand for electricity that exceeds supply. Wire and Cable Expo 2024 has learned that in such cases, building transmission and distribution lines helps transfer energy from resource-rich areas to densely populated regions, thus meeting the electricity needs for production and daily life.
High-Voltage Transmission Projects Can Reduce Energy Consumption
Minimizing current while increasing transmission voltage can reduce line losses and heat generation, while also ensuring the safety of transmission. In practical applications, raising transmission voltage can significantly decrease energy losses on transmission lines and improve transmission efficiency.
Cause of a High-Voltage Discharge Accident
When the high-voltage terminals of transmission lines or other equipment are exposed, coupled with various external factors such as the shape of electrodes, gas density, and external humidity, there is a higher probability of corona discharge occurring between the high-voltage conductors and surrounding gases. Corona discharge also exhibits the characteristics of a non-uniform electric field.
Causes of a Partial Discharge Accident
During operation, electrical equipment may be affected by high temperature, voltage, vibration, and other chemical actions, all of which can degrade the insulation performance of the equipment, leading to partial discharge phenomena. Additionally, Wire and Cable Expo 2024 has learned that partial discharge can further accelerate the deterioration of the equipment's insulation performance.
Accidents Caused by Equipment Failures
Unstable and unreliable operation of switchgear, or issues such as partial discharge, can lead to significant economic losses for the power system. Therefore, ensuring the stable and reliable supply of electricity and analyzing the causes of failures are essential to guarantee a steady power supply.
