摘要： In order to ensure the safety of maintenance personnel working on a photovoltaic system, a photovoltaic array is arranged to be within a safe voltage (such as 30V) when required. Provided are a method for controlling operation of a module level power electronics (MLPE) device associated with a photovoltaic string, and a photovoltaic system. In the method for controlling operation of a MLPE device, if it is determined that a current of the photovoltaic string associated with the MLPE device is less than a current threshold and coding information sent by a converter in the photovoltaic system is not received for a first preset time period, an output voltage or an output power of the MLPE device is controlled to be less than a corresponding threshold.

摘要： A method of making a sound reduction enclosure (10) for encapsulating a sound source (13), the method including taking a composite comprising a fibrous porous layer (14) and a thin, air impermeable, barrier layer (16), heating the composite and compressing the hot composite generally perpendicular to the interface between the porous layer (14) and the barrier layer (16) to form a tuned porous layer (14) by reducing the thickness and increasing the stiffness of the porous layer (14) to levels pre-determined using an upper frequency of the sound normally emitted by the sound source, and shaping the hot composite to form an enclosure (10) which at least partially encloses an interior space (12) in which the sound source (13) may, in use, be positioned.

摘要： A coupling assembly for elongate elements (1, 2) comprises a pin member (5) and a box member (6), said pin and box members having complementary and respective frusto-conical pin and box mating surfaces (12, 13). A bore (9; 9') has as a first opening a port (9a) configured for connection to an injection fluid reservoir (10) and a second opening (9b) penetrating the pin mating surface (12) or the box mating surface (13). The surfaces (12, 13) may be plain surfaces without helical threads or other pronounced protrusions configured for mating engagement, but comprise a textured finish in order to augment static friction between the surfaces (12, 13) when the surfaces are connected. A region (R b ) of the box surface (13) comprises a wall thickness (ta) which is less than the thicknesses (t b , t c ) of the adjacent box walls; and/or a region (R p ) of the pin surface (12) comprises a wall thickness (td) which is less than the thicknesses (te, tf) of the adjacent pin walls; and/or a region (R b ) of the box surface (13) comprises a material of a lower modulus of elasticity than the material of a corresponding region (R p ) of the pin surface (12), or vice versa.
