Abstract: Based on the mathematic theory for arc extinguishing, Mayr’s equation, we theoretically derived parameters of the test device for arc extinguishing, including the average speed of the contacts, size of nozzle, distance of the contacts, etc. Through qualitative analysis of elements and character parameters in arc extinguished chamber, as well as the experience of GCB design, mathematic theoretical calculation and arc extinguishing test, we came up with a tentative calculation and an estimation method for pressed arc extinguished chamber, which provide accordance for relative arc extinguishing test study.
