摘要： A surge protective device (SPD) module includes a module housing, first and second module electrical terminals mounted on the module housing, a gas discharge tube (GDT) mounted in the module housing, and a fail-safe mechanism mounted in the module housing. The GDT includes a first GDT terminal electrically connected to the first module electrical terminal and a second GDT terminal electrically connected to the second module electrical terminal. The fail-safe mechanism includes: an electrically conductive shorting bar positioned in a ready position and repositionable to a shorting position; a biasing member applying a biasing load to the shorting bar to direct the shorting bar from the ready position to the shorting position; and a meltable member. The meltable member maintains the shorting bar in the ready position and melts in response to a prescribed temperature to permit the shorting bar to transition from the ready position to the shorting position under the biasing load of the biasing member. In the shorting position, the shorting bar forms an electrical short circuit between the first and second GDT terminals to bypass the GDT.

摘要： An electronic module for protecting power semiconductor devices of an HVDC converter against high current surges and damaging electrical discharges includes a capacitor, a short circuit device, a movable portion, a short circuit portion and a spring element. The short circuit device is connected in parallel with the capacitor and has first and second busbars. The movable portion is connected to the first busbar and the short circuit portion is connected to the second busbar. The spring element is arranged between the movable portion and the short circuit portion. When a short circuit current flows through the first busbar, an electromagnetic force between the busbars causes the first busbar to repel the second busbar and move towards the short circuit portion. The latter provides a short circuit path connecting the first busbar to the second busbar short circuiting the capacitor and bypassing the power semiconductor devices of the HVDC converter.

摘要： Certain aspects are directed to a thermal fuse for preventing overheating of RF devices in a telecommunication system. In one embodiment, an RF thermal fuse comprises a body: a conductive bolt positioned in the body, the conductive bolt having a length sufficient to provide an impedance at a point of protection on a transmission line in response to the conductive bolt contacting a live conductor of the transmission line, wherein the impedance reflects a portion of the incident power of an RF signal from an RF signal source; and a driving mechanism that causes the conductive bolt to selectively contact the live conductor in response to an event.

摘要： The invention relates to a switching device for short-circuiting and earthing at least two phases in an electric power network. The device comprises a first phase contact, a second phase contact, and an earthed, movable contact, which can, on the one hand, assume a first position, where the contact is insulated from the phases, and, on the other hand, a second position, where the contact is connected to the phase contacts and thereby earths and short-circuits the phases. The device is characterized in that the first phase contact and the second phase contact are axially displaced from each other and that they are disposed around the movable contact, and that the contact is cylinder-shaped and comprises two circumferentially disposed contact areas, which are axially displaced from each other and intended to connect to the phase contacts in the second position, so that the phases are short-circuited and earthed via the contact, and that the device comprises electrically insulating areas, which are adapted to abut against the phase contacts in the first position.

摘要： A vacuum arc interrupter that includes a vacuum chamber assembly and a pressure chamber assembly. The vacuum chamber assembly includes a first, fixed contact disposed within the vacuum chamber and a second, movable contact disposed within the vacuum chamber. A rod is coupled to, and in electrical communication with, the second contact. The rod is structured to move between a first position wherein the second contact is spaced from the first contact and a second position where the first and second contacts are in electrical communication with each other. The pressure chamber assembly has a gas generation device and a cylindrical barrel defining a pressure chamber with a first end and a second end. The barrel second end has an opening. A piston assembly is disposed in the pressure chamber and coupled to the rod, which passes through the second, open end. The gas generation device is coupled to the pressure chamber assembly and in fluid communication with the barrel and the piston assembly. Upon generation of a gas by the gas generation device, the piston moves within the barrel causing the rod to move from the first position to the second position.
