With the rapid development of multiterminal high-voltage direct current (HVdc) transmission systems, the research and development of high-speed and stable high-voltage dc circuit breakers have received attention. Among them, mechanical dc circuit breakers based on manual zero-crossing dc breaking technology have been applied in practical projects, …
Energies | Free Full-Text | Real-Time Monitoring of the Vacuum
The internal pressure of a vacuum interrupter (VI) is increased by arc heat, ceramic cracking, gas leakage, and manufacturing defects. Accordingly, the dielectric strength of VI rapidly decreases. To improve the reliability of power transmission, efficient maintenance through the real-time monitoring of the vacuum degree is essential. …
New vacuum arc control technology; SADE-Application to vacuum interrupter…
2004. The high current interruption capability has been increased by a factor of two in the same electrode area compared with the existing AMF (axial magnetic field) technology by applying the new vacuum arc control method, SADE (self arc diffusion by electrode). The axial magnetic field profile of the SADE is optimized so as to diffuse the ...
Energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...
Vacuum Switching Technology for Future of Power Systems
First, current switching in vacuum is an eco-friendly technology compared to switching in SF6 gas, which is the strongest greenhouse gas according to the Kyoto Protocol. Vacuum, an eco-friendly natural medium, is promising for reducing the usage of SF6 gas in current switching in transmission voltage. Second, switching in vacuum achieves faster ...
Breakdown of shield gaps in vacuum interrupters
Abstract. The objective of this paper is to determine how the high-voltage discharging metal vapour deposited on the nearby ceramic inner surface influences the breakdowns of gaps between centre shield and end shield in vacuum interrupters. Two types of shield materials were selected, namely copper and stainless steel.
Electronics | Free Full-Text | A Novel Direct Current Circuit Breaker …
A reliable and cost-effective mechanical direct current circuit breaker (DCCB) is a promising solution for DC interruption. However, the typical mechanical DCCB has difficulty in interrupting a rated current, because the high oscillating current superimposed on the rated current generates a steep current slope at current zero …
