High Voltage Circuit Breaker, System, Vacuum Interrupter Module and Associated Drive Module

A high voltage circuit breaker system, comprising:

• a high voltage circuit breaker including
• a vacuum interrupter module having a vacuum interrupter housing and a pair of electrical contacts disposed in the vacuum interrupter housing, at least one of the pair of electrical contacts is movable relative to the other of the pair of electrical contacts to engage and disengage the electrical contacts from one another for switching a high voltage on and off,
• a drive module having a drive module housing and a drive member coupled with the at least one movable electrical contact, a central part of the drive member disposed in the drive module housing and insulated from an ambient air, and
• an actuator coupled to the drive member and moving the pair of electrical contacts relative to one another;
• and
• a control unit instructing the actuator to engage or disengage the pair of electrical contacts.

A vacuum interrupter module for a high voltage circuit breaker, comprising:

• a vacuum interrupter housing;
• a pair of electrical contacts disposed in the vacuum interrupter housing, at least one of the pair of electrical contacts is movable relative to the other of the pair of electrical contacts to engage and disengage the electrical contacts from one another for switching a high voltage on and off;
• and
• an encapsulation having an opening receiving a drive module, an insulating layer, a conductive layer, and a plurality of apertures permitting electrical connection to the pair of electrical contacts from an exterior of the vacuum interrupter module.
