A method for making a solid - sealed pole


The utility model proposes a 12kv embedded poles which can more effectively use the usable space for the heat dissipation element in the solid sealing pole and has no influence on the insulation performance of the entire circuit breaker provided with the solid pillar. The invention comprises the following steps: a embedded poles, which comprises an upper outlet, a vacuum interrupter, a lower outlet, a movable conductive rod, a contact spring, a vacuum interrupter including a static end and a movable end, And the upper end of the vacuum interrupter is connected with the lower outlet and the movable guide rod, the movable conductive rod has an inner surface and an outer surface, and the inner and outer surfaces of the movable conductive rod are tapered And the movable contact rod is arranged between the lower outlet and the vacuum interrupter, and the finger spring is arranged in the lower outlet and surrounds the movable conductive rod, wherein the heat sink is arranged above the upper outlet; the upper outlet and the vacuum The arc chamber, lower outlet and heatsink are embedded in the epoxy and are sealed by epoxy.

Advantages of embedded poles

图片
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...

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 sufficie...
