Working Principle Of Air Circuit Breaker
- Oct 28, 2016 -
Air switch or circuit breaker, which connected in the circuit, breaking and load operating current, and in the circuit and motor overload, short circuit, undervoltage under reliable protection. Circuit breakers of the static and dynamic contact and parallel bar design, using short circuit of electro-dynamic repulsion force to make static and dynamic contact disconnect, high breaking capacity, limiting performance is strong. Short, static contact aromatic insulation around gas and cools the arc function, arcing distance to zero. Circuit breaker arc-quenching Chamber using a metal gate structures, contact system with a repulsive force limiting mechanism, therefore, circuit breakers with high breaking capacity and limited capacity have double releaser. Inverse-time action bimetal Strip heat bending release action, instant action when iron core Street driven release action. Release methods are dynamic, electromagnetic and thermal compound release 3.

Air switch within the more sophisticated, the principle is very simple, it into the cable outlet series between a 10 and 20 laps of the inductor, current enough suction driven mechanical lever action protection. Safer without changing insurance is a very good recommend. Automatic air-switch, also known as low-voltage circuit breaker, by operational agencies, contacts, protection device (breaker), arc systems, and other components. Can be used for making and breaking load circuit can also be used to control are not frequently starting motors. It function is equivalent to the knife switch, over-current, under-voltage relay, thermal relay and the leakage current protective device, electrical part or all of the functions sum, is an important protection in low-voltage distribution network. Automatic air circuit breaker protection (overload, short circuit, under voltage protection, and so on), adjustable operating value and breaking capacity high, easy to operate, safe and so on, so is widely used at present.
