摘要:
A universal self-locking anatomical plate for posterior of acetabulum and pelvis, which includes a right plate (1), a plurality of screws (2) and a guiding sleeve (3). The right plate (1) includes a region-a, a region-b, a region-c, a region-d and a region-e, which can respectively fix a certain region of an acetabulum, the region-a is provided thereon with three first locking holes for receiving the locking screws, the region-b is provided thereon with at least two second locking holes, the region-c is provided thereon with two positioning holes and twelve third locking holes, the region-d is provided thereon with three fourth locking holes, and the region-e is provided thereon with one fifth locking hole. The plate has an optimized structure, and has three capabilities: good safety, good stability, and biomechanic matching. Additionally, the fitness of the plate to the surface of the acetabulum mode is good.
摘要:
This invention is related to a device and a method in an electric power plant for protection of an object (1) against over-currents from a network (3) or another equipment included in the high voltage plant, the device comprising a switching device (4) in a line (2) between the object and the network/equipment. The line (2) between the object and the network/equipment is connected to an arrangement (5) reducing over-currents towards the object (1), said arrangement (5) being actuatable for over-current reduction with the assistance of an over-current condition detecting arrangement (11-13) within a time period substantially less than the break-time of the switching device (4).
摘要:
The line section of a gas-insulated line contains a high-voltage electric conductor and a pressure pipe which is made from a thermoplastic material and filled with insulating gas. The pressure pipe holds the electric conductor on insulated supports. The pressure pipe has two pipes which are welded to one another on the end faces thereof, the end section being respectively widened to flare outwardly in the radial direction with the welding of the two pipes.
