Abstract
A high voltage circuit breaker comprises a vacuum interrupter module, a drive module, and an actuator. The vacuum interrupter module has 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. The drive module has a drive module housing and a drive member coupled with the at least one movable electrical contact. A central part of the drive member is disposed in the drive module housing and insulated from an ambient air. The actuator is coupled to the drive member and moves the pair of electrical contacts relative to one another.
