[Abstract]:Low-voltage electrical apparatus is widely used in electrical industry, it plays a very important role in distribution and protection of personal safety. It is an important aspect to study circuit breaker whether it can break reliably, because the breaking process of circuit breaker is more complicated. There are many fields involved, so it is an important subject to analyze and study the circuit breaker. This paper takes the TM-30/100 type plastic case breaker as the main research object, and based on the functions of ANSYSU Prop / E / Adams software, simulates the breaking process of the circuit breaker. It can be divided into the following aspects:. First, the model of circuit breaker is established in Pro/E according to the actual size, and then the model is imported into ANSYS. Firstly, the finite element thermal analysis of bimetallic sheet is carried out. The results are taken as the displacement of the free end of the bimetallic sheet in the dynamic simulation. Then the electromagnetic force of the electromagnetic release mechanism and the electric repulsion force between the static and static contacts under different current and open distance are calculated and loaded into the ADAMS as the load of the force. Secondly, the model is imported into ADAMS through special software. After loading according to the data of the previous analysis, the dynamic simulation of the circuit breaker's delay and transient breaking process is carried out, and the contact motion is observed. And the effect of electric repulsion force on the breaking process of contact in short circuit state.
