Assembly and seal test

Abstract: An assembly and method of testing the integrity of a sealing ring of a flexible pipe are disclosed The method includes locating a first sealing ring adjacent a first collar member and a layer of flexible pipe body; energising the first sealing ring by urging the sealing ring towards a primary pressure-retaining end fitting component, or by urging the pressure- retaining component towards the sealing ring; locating a second sealing ring adjacent the first collar member and a second collar member; energising the second sealing ring by urging the sealing ring towards the pressure-retaining component, or by urging the pressure-retaining component towards the sealing ring; and pressurising the region between the first sealing ring and the second sealing ring through a port extending towards the region to a predetermined pressure of 5 MPa or greater

Device for sealed passage of a partition for piping

Abstract: This duct partition passage (1, 10) comprises a fixing ring (7, 17) intended to be fixed on a duct (C), a support (2) intended to be fixed on a partition around the duct a duct passage opening (C), and a deformable annular seal (4, 14) provided between the fixing ring (7, 17) and the support (2).

Method to protect a power converter arrangement and power converter arrangement with a protective device

Abstract: A method is disclosed to protect a power converter arrangement with a power converter that has a DC side that is connected to a DC intermediate circuit, an AC side, and controllable switches that can be controllably switched at a high frequency to invert the DC voltage of the DC intermediate circuit into an AC voltage. A protective device that can be activated and deactivated is provided to protect the power converter from overload by connecting an external thyristor rectifier bridge with a brake resistor (R b ext ) to the AC side of the power converter. If a predetermined error situation is detected, the external thyristors are triggered to turn on, to activate the protective device. If it is detected that the predetermined error situation has disappeared, the external thyristors are turned off. A power converter arrangement with a device to protect against overload is also disclosed.
