Abstract ： In order to avoid serious fault caused by flash-over arc in the switch cabinet to the power equipment ，this paper
proposes a method of fast faulted circuit clearing by using super strong gas to achieve the purpose of restraining arc building ．
By setting a switch conductor between the bus bar and the breaker of the handcart type switch cabinet ， the faulted
equipment can be cut off quickly when there is an arc in the cabinet and the high-speed air flow immediately interrupts the
switch conductor in the circuit ．The paper uses the MATLAB software to modify the mayr arc model and establishes the
mathematical model of air flow
