A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

High Voltage, EarlyView.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

800 kV Fast Circuit Breaker: Mechanical Coupling Modelling, Buffer Design and Development

High Voltage, EarlyView.
ABSTRACT The 800 kV fast circuit breaker (CB) used in ultra‐high voltage (UHV) converter transformer can reduce the total breaking time to 25 ms. It significantly improves the action speed and breaking capacity of the CB, with promising broad application prospects.

The Impact of Various Contact Structures on the Microscopic Surface Condition of Vacuum Interrupters During Capacitive Switching

High Voltage, EarlyView.
ABSTRACT The double‐break vacuum circuit breakers (VCBs) that utilize series break technology effectively increase the switching capability for capacitive currents, elevate the withstand voltage level, and reduce the likelihood of restrike, all without compromising the breaking capacity for short‐circuit currents.

In Situ Grown UiO‐66‐NH2 on Nanocellulose Aerogels for Gas Capture

High Voltage, EarlyView.
ABSTRACT Sulphur hexafluoride (SF6) decomposition gases are toxic and corrosive, making the removal of these impurities essential for ensuring equipment safety and personnel health. To address this issue, this work developed a robust TEMPO‐oxidised cellulose nanofibril/chitosan (TOCNF/CS)@UiO‐66‐NH2 composite aerogel by in situ growth UiO‐66‐NH2 ...

Biochemical and structural characterization of a tail‐spike protein with depolymerase activity identified in a marine podovirus

Acta Crystallographica Section D, EarlyView.
The marine tail‐spike protein Dpo31 degrades the exopolysaccharide of its host and has structural features similar to those of other members of this protein class, despite similarity not being detected at the sequence level.Marine phages are, through the infection of their bacterial hosts, key regulators of microbiome and carbon fluxes in the ocean ...
