Terminology and definition of high voltage switchgear

Terminology and Definitions typically refer to the standardized definitions of specific terms or phrases used in a particular field or industry for clear communication and expression. In the field of electrical power or electrical engineering, for instance, when referring to "3.6 kV~40.5 kV AC Metal-enclosed Switchgear and Controlgear," relevant terminology and definitions might include:

1. AC (Alternating Current): It refers to the current whose direction changes periodically.

2. Metal-enclosed Switchgear: A device used for controlling, protecting, monitoring, and isolating electrical equipment in power systems. Its internal components are enclosed in a metal housing to prevent personnel access and enhance safety performance.

3. Controlgear: Equipment or systems that are used to operate, regulate, protect, or control devices or processes in electrical power systems.

4. Rated Voltage: The voltage value designed for equipment under normal operating conditions. For example, 3.6 kV~40.5 kV indicates the rated voltage range of the equipment, spanning from 3.6 kilovolts to 40.5 kilovolts.

5. Metal Enclosure: Refers to the use of a metal housing to enclose and protect electrical equipment and components, isolating personnel and potential hazardous environments.

6. Switchgear: A combination of devices used for controlling, isolating, and protecting electrical equipment. It typically includes circuit breakers, disconnectors, grounding switches, fuses, transformers, arresters, and other components.

7. Control Equipment: Equipment used for controlling, regulating, monitoring, and protecting devices or processes in electrical power systems, such as relays, controllers, meters, and other devices.
