Abstract:

A method is introduced to calculate the dynamic electric field of the arc-extinguish chamber in the circuit-breaker based on UG and ANSYS APDL. Through to establish analysis model and generate intermediate format in UG, which is imported into ANSYS. The arc-extinguish chamber continuous run in the process of electric field simulation of breaking operationis realized by using APDL analysis program, which can greatly reduce repeat modeling and calculation times of the movement of electric field. The relationship between the electric field intensity and breaking distance is obtained to confirm the opening & closing speed quickly needed by the test. This method can be used to calculate the electric field fast in the breaking process of multiple structures of a new product, and improve the efficiency of a new product design and development through providing the basis for breaking test of the new product by comparing with the mature products.

Key words: UG, ANSYS, APDL, arc-extinguish chamber, electric field simulation
