Switches are very common electrical equipment in our lives, and they have a great impact on our lives. And there are many types of switches now, the most common of which is the air switch. The air switch is also called a circuit breaker. Its working principle is that if the current in the circuit exceeds our rated current, the circuit will automatically open. And the low-voltage distribution network and electric drive system of the air switch are very important, and its functions are also very many. All air switches are widely used in our lives, so next the editor will tell you about them. About the air switch.

Introduction to air switch

Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that will automatically open as long as the current in the circuit exceeds the rated current. The air switch is a very important electrical appliance in the low-voltage distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing contact and breaking circuits, it can also protect short circuits, severe overloads and undervoltages in circuits or electrical equipment. It can also be used to start motors infrequently.

The air switch is the most commonly used electrical equipment in our lives, and it has a very good protective effect on the circuit. Its working principle is also very special. For example, as long as the current in the circuit is too large, The switch will automatically turn off. It can also provide timely protection when a short circuit occurs in a circuit or electrical equipment. The air switch is mainly composed of an auxiliary contact, an alarm contact shunt release, an electric operating mechanism of an undervoltage release, a rotating operating handle, and a handle locking device. When working, the sensitivity is also very high, and it also Intelligent control can be achieved.
