Air circuit breakers works

Air circuit breaker ACB works works works air circuit breaker ACB is the working principle of air switch air circuit breaker in the circuit as connected, breaking and

carrying rated current, and can occur in the circuit and motor overload short circuit, undervoltage case for reliable protection. Breaker dynamic and static contact

and touch bar design into a parallel form, the use of short electric repulsion generated by dynamic and static contact is open, high breaking capacity, current

limiting feature strongly. . Short circuit, the static contact insulating material surrounding aromatic gasification, from the cooling effect of arc, arcing distance

is zero. Circuit breaker interrupter sheet metal gate structure, the contact system has Repulsion limiting mechanism, therefore, the circuit breaker with high breaking

capacity and current limiting capability. [1]. With a double release. Inverse time operation is curved so that the bimetal heat release action, the instantaneous

action is the core mechanism driven iron street release action. Tripping methods are thermal, electromagnetic and double release three kinds. The air inside the switch

more sophisticated, but very simple principle. It is between the inbound and outgoing string a few 10 20 laps of the inductor current is sufficient to drive a

mechanical lever and pull action protection. Relatively safe and do not change the insurance, is a good recommendation. Automatic air switch is also known as low-

voltage circuit breakers, used to making and breaking load circuit can also be used to control the infrequent start motor. It functions as a knife switch, over-current

relay, voltage relay, thermal leakage protection relays and other electrical parts or all of the functions sum, low-voltage distribution network is an important

protective appliances. Automatic air switch with multiple protection functions (overload, short circuit, under voltage protection, etc.), the action is adjustable,

high breaking capacity, easy operation, safety, etc., so now is widely used. Structure and working principle of the automatic air switch by the operating agencies,

contacts, protection devices (various releases), interrupter system components. .
