摘要:
A computer, or other electrical component, having an electrical switch adapted to open when the cover of the chassis of the component covers the chassis and close when the cover is removed from the chassis. A mechanism is provided that turns on, and stays turned on, in response to the closing of the switch for providing an output. An indication device is connected to the mechanism and is adapted to provide a corresponding indication when the mechanism turns on.
摘要:
A low cost voltage disturbance mitigation system is capable of providing continuous power to a load despite short interruptions or sag disturbances of the utility power. The interruption and sag mitigation system makes use of a combination of unique thermal and electrical properties of magnetic components, power semiconductor devices, and high-discharge-rate energy storage devices. It also facilitates a modular solution that can be easily and economically scaled up or down for use over a wide range of voltage and power levels, e.g., 480 V to 36 kV and 500 kVA to 10,000 kVA.
