摘要： A puffer switch has a cylindrical shell filled with an electrically insulating gas, such as sulphur hexafluoride. A plurality of spaced parallel plates cooperating with the shell for defining a separate compression chamber or volume for each phase of an electrical power circuit that is to be switched. Located in each volume is at least one set of contacts which are subject to arcing as the contacts open or close. A movable contact in each of the sets of contacts has an associated impeller blade which is mounted to rotate with the movable contact and to sweep through the volume for compressing insulating gas in front of the impeller blade. A nozzle associated with the impeller blade directs the compressed insulating gas onto the set of contacts at a point where the arc is possible. The switch is assembled in a low cost manner by supporting spaced parallel plates defining the volumes between them as a slip-in unit which fits into a shell. A thermosetting plastic is used for parts which become hot. A lower cost thermoplastic is used for most parts which do not become as hot.

摘要： A high-voltage loadbreak switch operates submersed in a dielectric fluid and may be configured to switch one or more phases of power using one or more phase switches. Each phase switch may include first and second stationary contacts. The first stationary contact may be connected to a phase of a high-voltage power source. Each phase switch also may include a non-stationary contact. The non-stationary contact may be placed in a first position to electrically couple the first stationary contact to the second stationary contact, and in a second position to decouple the first stationary contact and the second stationary contact. The region of motion of the first non-stationary contact between the first position and the second position includes an arcing region. The high-voltage loadbreak switch uses a fluid circulation mechanism to improve circulation of the dielectric fluid through the arcing region. To suppress arcing between different phases, a non-conductive baffle may separate different phase switches when more than one phase switch is used. A non-conductive baffle also may separate a phase from ground to prevent phase-to-ground arcing.

摘要： Disclosed is a multipole high-voltage circuit breaker of the type comprising a housing into which two stationary contacts per pole extend and a rotatable current bridge which connects and disconnects the stationary contacts upon rotation thereof. Both the stationary contacts and the contacts on the movable bridge are provided with preliminary switching points or contacts and main contact points or contacts. The preliminary contact points make contact before the main contact points and break contact after the main contact points. The arrangement permits arcing at the preliminary contact points only and thereby increases the life of the main contact points.
