It can make the safety technology effective and reliable operation during manufacturing, installation, using, management, inspection and repairing. Through the intrinsically safe understanding of interlocking device, analyzing the principles of frustrated groove and seal lock mechanism and its effect on the intrinsically safe deeply, it is found that the design of intrinsically safe should be carried out to effectiveky control and avoid the safety accidents happening when the equipment system is failure, operator error operation or false judgment. Only mandatory inspection of interlock is implemented, the safe of equipment operation can be guarantee effectively. Keywords Aut
