Advantages of embedded poles

First, modular design, simple structure, less removable parts, high reliability;Second, very high insulation rod capacity. It will surface insulation into volume insulation, compared to air insulation, reducing the impact of the environment, greatly improving the dielectric strength.

It can make the circuit breaker size, is conducive to miniaturization of the switchgear.Previously, the general vacuum interrupter insulation shell exposed to the air, there is outside the dust, wet pollution problems. To reduce this effect, the vacuum interrupter housing is required to have sufficient length, which not only affects the miniaturization of the vacuum interrupter, but also the performance and reliability of the vacuum interrupter. The solid-sealed pole has the following advantages: Compared with the traditional assembled pole, the number of parts of the embedded poles is reduced greatly, the overlapping surface of the conductor is reduced from 6 groups to 3 groups, and the connection bolt is reduced from 8 to 1 to 3 The simple structure greatly improves the reliability of the circuit breaker; since the vacuum interrupter is embedded in the solid material, there is no need for any further processing, and the solid pillar can be made very high 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.
