VS1(ZN63A)-12 permanent magnet vacuum circuit breaker

The main purpose and scope of application of the permanent magnet vacuum circuit breaker product/Indoor high-voltage vacuum circuit breaker equipped with a permanent magnet operating mechanism is a three-phase AC, indoor device with a rated voltage of , which can be used for industrial and mining enterprises, power plants and substation electrical facilities. For control and protection purposes, and suitable for places with frequent operations. The circuit breaker can be operated frequently and has multiple breaking capabilities. The circuit breaker is designed with a front and rear split structure. It can be used as a fixed installation unit or as a separate handcart when equipped with a chassis. This circuit breaker adopts a permanent magnet operating mechanism, which has the characteristics of small number of parts, simple operating procedures and high reliability.
2 Normal use environmental conditions The ambient temperature is not greater than ℃, and is not lower than ℃. The altitude is not greater than the daily average relative humidity of the air, and the monthly average is not greater than the earthquake intensity. Note that deviations from normal use conditions can be contacted with the manufacturer Resolve through negotiation.
Three Structures
The overall structure of the circuit breaker/vacuum circuit breaker equipped with a permanent magnet operating mechanism can be divided into two types: fixed type and withdrawable type. The overall structure adopts the form of operating mechanism and arc extinguishing chamber arranged front and back. The main conductive circuit part is divided into three-phase floor-standing structure. The vacuum arc extinguishing chamber is installed longitudinally in a tubular insulating cylinder. The insulating cylinder is cast by epoxy resin using a process Therefore, it is particularly resistant to creepage. This structural design greatly reduces the accumulation of dust on the surface of the arc extinguishing chamber. It not only prevents the vacuum arc extinguishing chamber from being affected by external factors, but also ensures that even in humid, hot and severely polluted environments , can also exhibit a high resistance state to voltage effects.
Permanent magnet operating mechanism The permanent magnet operating mechanism is composed of a total of seven parts, which are the static iron core, which provides the magnetic path for the mechanism, and the moving iron core, which is the most important moving part of the entire mechanism. It is the permanent magnet, which provides the mechanism with The opening coil is used as the driving rod to provide the power required for holding, which is the connection link between the mechanism and the circuit breaker transmission mechanism. It overcomes the inherent shortcomings of the traditional electromagnetic mechanism and spring mechanism, and eliminates the vulnerable energy storage lock mechanical device in the traditional mechanism. It has the characteristics of simple structure, long life, reliable performance, wear resistance and maintenance-free.
