High-voltage equipment
Thread Content
What is the role of high-voltage circuit breakers, high-voltage isolators, high-voltage load switches, and high-voltage fuses in case of a short circuit? What are the differences between them, and what are the combination patterns in complete sets of equipment? What is the connection and difference between them and the air switches and leakage protectors used in daily life?
What are the functions of high-voltage circuit breakers, high-voltage isolators, high-voltage load switches, and high-voltage fuses in electrical circuits? What are the differences between them? And what are the combination patterns in complete sets of equipment? What is the connection and difference between them and the air switches and leakage protectors used in daily life?
I made a mistake; it’s the role in the circuit.
High-voltage circuit breakers, high-voltage load switches, and high-voltage fuses can interrupt normal load current as well as short-circuit fault current, although their ability to interrupt short-circuit current varies； In principle, it functions in the same way as a low-voltage air switch (commonly known as a circuit breaker). A typical leakage protector not only functions to cut off the load current and fault current, but also shuts off the switch in the event of a leakage. High-voltage isolating switches and low-voltage isolating switches serve the same purpose: they cannot interrupt normal load currents, let alone fault currents; they merely serve to isolate circuits and are used during maintenance or when changing the operating mode.
