The cleaning bundle includes the Speed Clean Kit, which transforms your upright vacuum into a handheld unit – perfect for stairs, upholstery, and those awkward, tight spaces that standard ...

May 12 (Reuters) - The U.S. Nuclear Regulatory Commission (NRC) has launched a special inspection at the Quad Cities Generating Station in Marseilles, Illinois, following discovery of inoperable ...

Abstract: For phase-controlled vacuum breakers, the acting time of the actuator should be precise. The variation of capacitor voltage, capacitance, and environmental temperature impact the dispersion ...

Abstract: The dielectric recovery strength (DRS) of vacuum circuit breaker (VCB) interrupter is closely related to the travel characteristic of contact, which determines the overvoltage caused by ...

Abstract: The hybrid circuit breaker (HCB) which consists of SF6 interrupter (GI) and vacuum interrupter (VI) connected in series has been put forward to be applied in HVDC system. The paper analyses ...

Abstract: In this paper, based on the motion and dynamic coordination characteristics of the high-voltage vacuum circuit breaker and the motor control mechanism, the mathematical model of the ...
