Fluidic actuator

A fluidic actuator includes a central elastic tube with an interior bore and a surrounding sheath formed of braided fibers. End fittings are attached to the tube and sheath at first and second ends thereof and include a cap with a hollow cavity into which an end section of the tube and sheath are inserted and embedded in a hardened adhesive. The hardened adhesive seals off the ends of the tube and strongly bonds the fibers of the sheath to the end caps to provide strong mechanical connections. A fluid coupling may extend through one of the end caps to connection to an end of the tube, with an interior bore in the coupling in communication with the bore in the tube to allow fluid under pressure to be supplied to the interior of the tube. A liquid lubricant may be held in the fibers of the sheath to provide lubrication between the elastic tube and the fibers of the sheath to reduce wear and abrasion of the tube and extend the service life of the actuator.

Current-limiting arc-extinguishing shunted exciter tripping type earthing short circuit protection device

The present invention belongs to the technical field of protecting single-phase grounding short-circuit which results from insulation failure of single-phase and three-phase power consuming equipment in a low-voltage power network, and in particular relates to a current-limiting, arc-eliminating and excitation-dividing tripping type grounding short-circuit protection device. The technical proposal consists of a circuit breaker actuating device, a circuit breaker starting mechanism, and a short-circuit detection actuating mechanism. Because the current or voltage signals which are used for actuating the protection device is not related to the short-circuit current of the original grounding short-circuit loop, the protection device solves the problem of dependence on the fuse for the grounding short-circuit failure in the long term and the problem that the short-circuit switch with current as a parameter can not easily generate the maximum allowable temperature rise (igniting fire) in the loop wire within the protective range, and in particular in the terminal insulating wire of the power consuming equipment, so as to timely cut off the circuit.
