Current path structure provides a current path between an interrupter assembly and a resistor assembly of a dead tank circuit breaker and includes an electrically conductive fixed support having first and second ends. The first end is fixed to one of the interrupter assembly or the resistor assembly. A substantially hollow, electrically conductive conductor has first and second ends, with a connector at the first end thereof. The connector is removably connected to the other of the interrupter assembly or the resistor assembly. Coupling structure removably couples the conductor with the fixed support such that when coupled, the current path structure is in an operative position electrically connecting the interrupter assembly with the resistor assembly, and when decoupled, the fixed support can be moved into telescoping relation within the conductor defining a collapsed position of the current path structure. |

An electrical switch includes a pivotally supported blade, a toggle mechanism, and an operating mechanism. The operating mechanism is drivable in a first direction to pivot the blade about a first axis and toward a closed blade position. When pivoting toward the closed blade position, the toggle mechanism inhibits the blade from pivoting about a second axis. Upon reaching the closed blade position, continued motion of the operating mechanism in the first direction causes the toggle mechanism to pivot the blade about the second axis toward a closed contact position. In the closed contact position, the blade contacts at least one blade contact to electrically connect the blade and a first electrical terminal. |

A pole and actuating assembly for a circuit breaker includes a frame, a plurality of pole and actuating members including a pair of outer pole and actuating members fixed to the frame and a center pole and actuating member disposed there-between and rotatably fixed with respect to the frame. The center pole and actuating member, in an installation position, has a vertical height greater than a vertical height of each of the outer pole and actuating members. Bracket structure is coupled to the frame to permit rotation of the center pole and actuating member to be disposed securely at an acute angle with respect to the frame, thereby reducing the vertical height of the center pole and actuating member in a travel position thereof. |

The invention relates to a conductor for electrical equipment, including at least two electrically-conductive material support elements spaced apart from each other along a longitudinal axis (Y) and at least four electrically-conductive material structural sections elongate along the longitudinal axis (Y), curved transversely to the longitudinal axis, and supported by the support elements; wherein the support elements further hold apart in pairs the at least four curved structural sections, the separation maintained between two curved structural sections of a pair defining an open area extending transversely to the longitudinal axis and at least between the support elements, said open area reducing in size progressively and continuously. This conductor may advantageously form a movable contact (blade) of a high-voltage disconnector. |

Techniques for making high voltage connections are disclosed. In one particular exemplary embodiment, the techniques may be realized as an electrical switch. The electrical switch may comprise a component extending from a first electrical contact to a second electrical contact. The component may also comprise a non-conductive section and a conductive section. In a first mode of operation, at least a portion of the non-conductive section may be positioned between the two electrical contacts to insulate the two electrical contacts. In a second mode of operation, the conductive section may be positioned between the two electrical contacts to connect the two electrical contacts. |

A switch includes a blade-type moving contact that extends in a radial direction from a turning center and reciprocates such that its free end draws a turning locus, and a fixed contact that moves toward and away from the moving contact in a turning range of the moving contact. The blade-type moving contact and the fixed contact are accommodated a tank. The moving contact is supported by the movable-side support conductor. The fixed contact is supported by the fixed-side support conductor. An opening through which the moving contact enters is arranged to be opposed to a turning center of the moving contact. The movable-side support conductor and the fixed-side support conductor are arranged substantially on a same straight line extending along a center axis of the tank. |

A make-before-break selector switch for use in high-voltage applications allows power to a load to be switched from a first power source to a second power source such that the second connection is made before the first is broken. The selector switch includes a blade coupled to a selector switch control such that the blade may be placed in a first position to electrically couple a first power source electrical contact to a load electrical contact and in a second position to electrically couple a second power source electrical contact to the load electrical contact. T-shaped and v-shaped blade implementations are examples of configurations that may be used. |

An air-insulated high-voltage disconnector includes a pivoting arm which pivots at one end about a horizontal axis perpendicular to the axis of the arm and turns about its axis. The free end of the arm carries a contact member referred to as the hammer cooperating, in the closed position of the disconnector, with a jaw including a jaw support to which are fixed two facing rows of contact fingers. The contact fingers are tubular and open at both ends. |
