What is the difference between an air switch and a circuit breaker?

Air switch, also known as air circuit breaker, refers to a circuit breaker in which the contact is separated in the air under atmospheric pressure. It is a kind of circuit breaker; it can be seen from the definition that the air switch is simply one of the circuit breakers. But what are the differences between the two in terms of function? Xiaobian reminds you to take a look at the following major points!

The main differences between the air switch and the circuit breaker are:

1. The air switch generally functions as an "isolation" and a "protection device" in a small current circuit, also called an automatic switch, also called an air circuit breaker.

2, the circuit breaker has a good arc-extinguishing ability, automatic tripping in the case of short-circuit and high-current circuit; in high-voltage, high-current circuits, it is often used as an operating device for power failure, power transmission, and switching off and off load.

3, the difference of voltage levels: the general air switch combined with the voltage level is less than 500V, and the circuit breaker can usually be used for all voltage levels above 220V.

4, the ability to interrupt the current is different: the general circuit breaker can withstand the load and short-circuit current is greater.

5, the difference between arc extinguishing medium and mode: the arc extinguishing medium and method of the circuit breaker not only have air circuit breaker, but also vacuum circuit breaker, multi-oil circuit breaker, oil-less circuit breaker, sulfur hexafluoride circuit breaker and so on.

6. The difference between the supporting equipment: Generally speaking, the measurement of the circuit breaker is relatively more complicated than the opening of the circuit, and the equipment of the logic and the organization of the executive department is more complicated.

7. The circuit breaker has various models such as vacuum circuit breaker and SF6 circuit breaker. Its breaking current is larger than ordinary air switch, and the breaking capacity is also larger. Vacuum circuit breaker is generally used for 6KV system, SF6 is open circuit. The device is used in the 500KV substation, both of which use DC 110V as the control power supply, and will be triggered by the control signal. The general open air is used in the 380/220 system, which is equivalent to the knife gate.
