Interruptor de vacío

"Vacuum Circuit Breaker" gets its name because its arc extinguishing medium and the insulation medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. Applications in the power grid are relatively widespread. High voltage vacuum circuit breaker is an indoor power distribution device in a 3 Ah10kv, 50hz triple Interface System.Protección y control de equipo eléctrico, como plantas industriales y mineras, centrales eléctricas y subestaciones.Para facilitar el mantenimiento y la utilización frecuente, los disyuntores pueden instalarse en armarios centrales, dobles y fijos para controlar y proteger el equipo eléctrico de alta tensión.

Historia de los interruptores de vacío

In 1893, Rittenhouse in the United States proposed a vacuum interrupter with a simple structure and obtained a design patent. In 1920, the Swedish Foga Company made the first vacuum switch. Research results published in 1926 and others also show the possibility of breaking the current in a vacuum. However, due to the small breaking capacity and the limitation of the development level of vacuum technology and vacuum materials, it has not been put into practical use. With the development of vacuum technology, in the 1950s, the United States only made the first batch of vacuum switches suitable for cutting off capacitor banks and other special requirements. The breaking current is still at the level of 4 thousand amps. Due to advances in vacuum material smelting technology and breakthroughs in the research of vacuum switch contact structures, in 1961, production of vacuum circuit breakers with a voltage of 15 kV and a breaking current of 12.5 kA began. In 1966, 15 kV, 26 kA, and 31.5 kA vacuum circuit breakers were trial-manufactured, so that the vacuum circuit breaker entered a high-voltage, large-capacity power system. In the mid-1980s, the breaking capacity of vacuum circuit breakers reached 100 kA. China began to develop vacuum switches in 1958. In 1960, Xi'an Jiaotong University and Xi'an Switch Rectifier Factory jointly developed the first batch of 6.7 kV vacuum switches with a breaking capacity of 600 A. Subsequently, they were made into 10 kV and a breaking capacity of 1.5. Qian'an three-phase vacuum switch. In 1969, Huaguang Electron Tube Factory and Xi'an High Voltage Apparatus Research Institute produced a 10 kV, 2 kA single-phase fast vacuum switch. Since the 1970s, China has been able to independently develop and produce vacuum switches of various specifications.

Condiciones técnicas del interruptor de vacío

Los interruptores de vacío suelen clasificarse en varios niveles de tensión.El tipo de presión baja se utiliza normalmente para electrodomésticos resistentes a explosiones.Como las minas de carbón.

Tensión nominal de 5.000 a, con un corte de 50 a más, hasta 35 kv.

Hasta el decenio de 1980, los interruptores de vacío se encontraban en las primeras etapas de su desarrollo, con una exploración tecnológica continua.No es posible establecer normas técnicas.Las normas relativas a los productos no se establecieron hasta 1985.
