Today introduced ZW32 permanent magnet vacuum circuit breaker overall structure and permanent magnet operating mechanism, where I am nonsense how much ZW32 permanent magnet vacuum circuit breaker is a small installation of electrician partners often use a circuit breaker, the end just a bit Electrician friends come to my house to see, I would like to know ZW32 permanent magnet vacuum circuit breaker, from two aspects to me specifically introduced ZW32 permanent magnet vacuum circuit breaker overall structure and permanent magnet operating mechanism of the structural characteristics.
The overall structure of the circuit breaker ZW32 permanent magnet vacuum circuit breaker (with permanent magnet operating mechanism) can be divided into fixed circuit breaker and withdrawable circuit breaker two. The overall design structure is in the form of an operating mechanism and an arcing chamber. The main conductive circuit part can be divided into three-phase floor type design structure. The vacuum interrupter is installed in a tubular insulation cylinder, Oxygen is cast from APG process, so it is particularly resistant to creepage. This structure is designed to greatly reduce the accumulation of dust on the surface of the interrupter, not only to prevent the vacuum interrupter from being affected by external factors, but also to ensure that even in the Hot and severe pollution of the environment, the voltage can also show a high resistance state.

2, permanent magnet operating mechanism Permanent magnet operation mechanism consists of seven parts: 1 for the static core, for the body to provide magnetic circuit; 2 for the moving core, is the most important movement of the whole body parts; 3,4 For the permanent magnet, for the organization to provide the necessary power to maintain; 5,6 for the gate coil; 7 for the drive rod, is the mechanism and the circuit breaker transmission link. It overcomes the inherent drawbacks of the traditional electromagnetic mechanism and the spring mechanism, and eliminates the fragile energy storage and locking mechanism of the traditional mechanism. It has the characteristics of simple structure, long life, reliable performance, wear resistance and maintenance.
Listen to his introduction to the ZW32 permanent magnet vacuum circuit breakers, I am deeply impressed by his understanding of such circuit breakers.
