摘要:
An air-insulated high-voltage disconnector including a pivotally-mounted arm suitable for pivoting at one of its ends about a horizontal axis that is perpendicular to the axis &Dgr; of the arm, and also suitable for turning about its own axis &Dgr;, the free end of the arm carrying a contact part or “hammer” which, when the disconnector is in the closed position, co-operates with a jaw comprising a jaw support to which two facing rows of contact fingers are fixed, wherein the hammer is equipped with contact tabs co-operating with the contact fingers, each contact tab forming a wedge of angle &bgr;, which wedge acts, during disconnector closure, to meet the corresponding row of fingers with an angle of attack &agr;, said angle of attack &agr; being less than 90°.
摘要:
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.

In a sulfur hexafluoride high-tension circuit-breaker, a condenser/evaporator (8), disposed beneath and in communication with the inside of a support column, is partially filled with an insulating material (11), having at least one well (10) formed therein, with a heater element (9) being disposed inside the well, the surface of the insulating material (11) being connected to the bottom of the well via ducts (13, 14).
摘要:
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.

The present invention is directed to an optical fiber (12,14) connector (10) comprising a longitudinally extending body (16), said body (16) comprising a first end (18) and a second end (20), and said body having a conduit (22) extending from said first end (18) to said second end (20), and said body (16) comprising a plurality of finger projections (24,26) that extend longitudinally at each end of said first (18) and second ends (20), the connector assembly (10) including a first collar circumferentially coupled to said first end (18) of said connector (10) and a second collar (36) circumferentially coupled to said second end (20) of said connector (10), the connector assembly (10) comprises a connector housing of four portions (38), which, when assembled, define a connector chamber for receiving and retaining a connector (10) as aforesaid.
摘要:
The invention is directed to a connector (10) for connecting optic fibres (12, 13). The connector has a longitudinally extending body (14). The body has a first end and a second end. The body has a pass-conduit (20) extending from the first end to the second end. The body is divided into a plurality of fingers (22, 26) formed by slots (28) that extend longitudinally at each of the first and second ends and many be circumferentially offset from each other by any angel. The connector may be made from material that has a shape memory.
摘要:
The present invention provides a mechanism for converting rotary motion into translation motion, the mechanism comprising a first member which is rotated and which is constituted by a cylinder having a helical spring threaded thereover and fixed thereto at at least one point, and a second member for being driven in translation by the first member and including slots for co-operating with the thread constituted by the spring. This transmission system is intended, in particular, for use in relatively rudimentary mechanisms of the type used in agricultural machinery.
