Long-Term Reliability Design of High-Voltage Doorknob Capacitors in Coupling Devices
High-voltage coupling devices are often deployed in harsh, maintenance-prone environments such as substations and transmission lines. Their core component, the coupling capacitor, must withstand continuous electrical stress, temperature cycling, and potential transient overvoltage surges. Any premature failure could lead to communication interruption or monitoring system failure, with serious consequences. The long-term reliability and robust design of high-voltage door handle capacitors are the cornerstones of ensuring trouble-free operation of the entire system.
Harsh Operating Conditions for Capacitors in Coupling Devices
Continuous high-voltage stress: Capacitors operate under the electric field of rated power frequency voltage and its harmonics for extended periods, continuously testing the dielectric strength of the dielectric.
High-frequency current and thermal stress: Carrier signal current flows through the capacitor, causing dielectric loss and resulting in temperature rise, especially when the signal power is high.
Environmental stress: Outdoor devices must withstand environmental factors such as daytime temperature fluctuations, humidity, ultraviolet light, and even pollution.
