What is the difference between a sealed vacuum circuit breaker and a non-solid type vacuum circuit breaker?
What is a embedded poles?
The vacuum interrupter and circuit breaker-related conductive parts at the same time embedded in epoxy resin such as easy solidified solid insulation material to form the pole, so that the entire circuit breaker pole into a whole component.
The 12kv embedded poles has the following two advantages:
First, modular design, simple structure, less removable parts, high reliability;
Second, very high insulation rod capacity. It will be insulated into a volume insulation, compared to air insulation, reducing the impact of the environment, greatly improving the dielectric strength.
It can reduce the size of the circuit breaker, 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 17.5kv embedded poles is greatly reduced, 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-sealed pole can be made very high The effect of the external environment on the vacuum interrupter is minimized after the vacuum interrupter is embedded in the solid material.
