1.Modular design, simple structure, few detachable parts, and high reliability.
2.The extremely high insulating rod capacity.
Embedded pole turns surface insulation into volume insulation, which reduces environmental impact and greatly improves insulation strength compared to air insulation.Embeded pole can reduce the size of the circuit breaker, which is beneficial to the miniaturization of the switch cabinet.
In the past, the insulating casing of the general vacuum interrupter was exposed to the air, and there was a problem of being polluted by external dust and moisture. In order to reduce this effect, the shell of the vacuum interrupter is required to have a sufficient length, which not only affects the miniaturization of the vacuum interrupter, but also affects the performance and reliability of the vacuum interrupter. The
embedded pole has the following advantages: compared with the traditional assembled pole, the number of parts of the solid-sealed pole is greatly reduced, the overlapping surface of the conductor is reduced from 6 groups to 3 groups, and the connecting bolts are reduced from 8 to 1~3, The simple structure greatly improves the reliability of the circuit breaker; since the vacuum interrupter is embedded in the solid material, no further processing is required, and the
embedded pole can achieve a high dielectric strength; After the vacuum interrupter is embedded in the solid material, the influence of the external environment of the pole on the vacuum interrupter is minimized.
