摘要： The invention provides a method and a system (9) for testing a switching installation (30) for power transmission installations. In this case, the switching installation (30) comprises a switch (2) which selectively connects or disconnects a first side (6) of the switch (2) to a second side (7) of the switch (2), and comprises two grounding disconnectors (10, 11). Each of the two grounding disconnectors (10, 11) is provided in order to selectively connect the first side (6) or the second side (7) to ground (1) or disconnect said first side or said second side from ground (1). In order to test the switching installation (30), a current is generated through the switch (2) and a magnitude of the current through the switch (2) is determined. In this case, the two grounding disconnectors (10, 11) are closed during the process of generating the current and the process of determining the magnitude of the current.

摘要： A circuit interrupting assembly for an electrical power distribution system, comprises a first insulator (12) for connection to the power distribution system, the first insulator having a first conductive bracket (208). A circuit interrupting device (10) is coupled to the first conductive bracket and includes a circuit interrupter (18) having a dielectric housing (36) enclosing a primary contact (32) and a movable contact (34), which is movable relative to the primary contact (32) between a closed position and an open position. An actuator (20) is coupled to and disposed adjacent to the circuit interrupter (18). The actuator is received in a housing (56) and includes a shaft (58) coupled to the movable contact (34), without insulation between the shaft and the movable contact, for moving the circuit interrupter between the closed and open positions upon occurrence of a fault current. First and second terminals (42, 118) are electrically connected to the circuit interrupter, at least one of which is connected to the first conductive bracket (208). A current path is defined between the first terminal (42), the circuit interrupter (18) and the second terminal (118), so that the potential of the circuit interrupter is the same as the potential of the power distribution system. The circuit interrupter (18) and the actuator (20) are not mounted in a grounded container. The first terminal, the circuit interrupter, the actuator, and the second terminal are ungrounded.

摘要： A shielded encapsulated vacuum interrupter with a ceramic vacuum chamber and opposing conductive end caps is provided. One end cap is electrically connected to a fixed contact, while an opposing end cap is connected to a moving contact. The moving contact is actuatable with the fixed contact for opening or closing an electric circuit. A floating shield inside the vacuum chamber connected to the vacuum chamber ceramic wall and spaced from the fixed and moving contacts is isolated and has a floating voltage potential. A portion of the vacuum chamber exterior ceramic wall is coated with a semi-conductive material and conductive voltage screens enclose a portion of the vacuum chamber exterior and are electrically connected to each conductive end cap of the vacuum chamber. The chamber and connected screens are encapsulated in a molded dielectric housing.

摘要： A circuit interrupting device (10) has a circuit interrupter (12) with a stationary contact (26) and a moveable contact (28). The movable contact is movable relative to the stationary contact between a closed position that allows current to pass through the circuit interrupter and an open position separating the contacts and preventing current from passing through the circuit interrupter. The movable contact is controlled by a solenoid assembly (14). The movable contact is connected to a plunger (62) of the solenoid assembly by a turnbuckle (16) and weld break assembly. The turnbuckle and weld break assembly permits adjusting the contact wipe distance and generates a hammer force to break any welds between the contacts of the vacuum interrupter.
