24KV 2000A Embedded Pole High Voltage Vacuum Circuit Breaker Smart Type

24KV 2000A Embedded Pole Smart Type High Voltage Vacuum Circuit Breaker

 Features of High Voltage Vacuum Circuit Breaker

      It embeds the conductive parts related to the vacuum arcing chamber and circuit breaker into the epoxy resin, which is a kind of solid insulation material that is easy to cure. Epoxy resin is poured on the outside for encapsulation, and the pole column is sealed to form an integral part of the whole circuit breaker pole column. Epoxy resin is not only the primary part of the main insulation, but also its mechanical support. Its electric field distribution is better than various forms of insulation diaphragm structure.

Application of High Voltage Vacuum Circuit Breaker

Difference between High Voltage Vacuum Circuit Breaker &traditional insulating cylinder

The embedded pole has the following advantages:

1. Modular design, simple structure, less detachable parts, simple installation and high reliability.

2. High insulating rod capacity. It turns surface insulation into volume insulation.

        In the past, the insulating shell of vacuum interrupter was exposed to the air, which was polluted by dust and humidity. In order to reduce this effect, the shell of the vacuum interrupter is required to have enough length, which not only affects the miniaturization of the vacuum interrupter, but also affects the performance and reliability of the vacuum interrupter.

      Compared with the insulating cylinder, the number of parts of the embedded pole is greatly reduced. The overlapping surface of the conductor is reduced from 6 groups to 3 groups, and the number of connecting bolts is reduced from 8 to 1-3. The simple structure greatly improves the reliability of the vacuum circuit breaker. Because the vacuum interrupter is embedded in the solid material, no further treatment is needed, and the embed pole can achieve high insulation strength. It is more conducive to the miniaturization design of vacuum circuit breaker and switchgear. When the vacuum interrupter is embedded in the solid material, the influence of the external environment on the vacuum interrupter is minimized. It is completely maintenance free in the service life of the product, which makes it have strong adaptability, and can be widely used in chemical industry, metallurgy, mining and other occasions.
