Heating effect of current bending deformation of the bimetal causes

Hot air circuit breaker tripping mechanism generally bimetal composition, when the current through, due to the thermal effect causes the current bimetal bending. If the current  air circuit breaker  the allowable range, that will lead to mechanical linkage mechanism, so that the air circuit breaker contacts open, that is, switch tripping,  circuit breakers . Overall  Voltage stabilizer  test rig into the air circuit breaker factory inspection and automatically adjusts quickly hot air circuit breaker tripping mechanism two parts, this system has a function switch, rapid testing and automatic adjustment of heat release two blocked. After a system reset, respectively, according to the position of the switch into its own program.
