Analysis Of The Manufacturing Process Of Sealed Pole

Date: | Read: 51

In the medium voltage field, especially at the 12 kV level, vacuum circuit breakers have become mainstream products. The pole insulation of vacuum circuit breakers has gone through air insulation-composite insulation-sealed insulation. The third generation of insulation is Embedded Pole, which uses the APG process to solidify the vacuum arc chamber and conductive terminals with epoxy resin to form an integrated pole. Since the vacuum arc chamber is encapsulated in epoxy resin, it is almost not affected by external dirt, moisture, etc. In addition, epoxy resin is not only the main insulation of the arc chamber, but also the mechanical support of the arc chamber. The electric field distribution is better than that of the traditional assembled pole. At the same time, the number of structural parts is reduced, the reliability of the conductive circuit is increased, and its application is becoming more and more extensive.
