摘要： An earthing module for a switchgear includes: a cylinder; a piston; a stored energy unit; and at least one photovoltaic cell. The cylinder connects to a part of a switchgear at earth potential. The piston moves within the cylinder from a standby position to a released position along an axis of the cylinder. When in the released position, the piston is in electrical connection with the cylinder. The stored energy unit is located within or associated with the earthing module such that activation of the stored energy unit moves the piston from the standby position to the released position. One or more of the at least one photovoltaic cell activates the stored energy unit based on radiation from an electrical arc of the switchgear impinging upon the one or more of the at least one photovoltaic cell.

摘要： The present invention relates to a bus conductor connection structure for electric field relaxation. The bus conductor connection structure for electric field relaxation includes: an enclosure filled with an inert gas; spacers coupled to two side end portions of the enclosure in a facing contact manner and having connection conductors; conductors provided with predetermined intervals being maintained inside the enclosure; and coupling portions formed in end portions of the conductors, wherein the coupling portion is coupled to the connection conductor in a close contact manner with bolts. Accordingly, the bus conductor connection structure for electric field relaxation is allowed to simply fixing conductors and assembling bolts of a gas insulated bus and to reduce a size of the bus by shortening an insulation distance between the bus and the ground by using a shape and arrangement for electric field relaxation.

摘要： A gas circuit breaker 40 automatically interrupts a fault current such as ground fault current flowing through a conductor 61 of a bus line 60. A high speed grounding switch 10 performs a higher grounding and its releasing operation than the open and close operation of the gas circuit breaker 40 during the open and close operation thereof and guarantees the current interrupting performance and the inter-electrode insulation performance of the gas circuit breaker 40. In association with the electrode arrangement of a disconnecting switch 20, bus lines 60A and 60B are disposed in horizontal direction, a stationary electrode 13 of the high speed grounding switch 10 is provided at the constitutional unit 21 of the disconnecting switch 20 so as to locate on the same straight line as the central axis of the bus line and the movable electrode 11 at the ground side is closed along the same straight line as the central axis of the bus line. The stationary electrode 13 can be provided at a bent corner or a branching portion while locating the stationary electrode 13 and the movable electrode 11 on the same straight line as the center axis of the bus line. Thereby, durability of a gas insulated switch gear device provided with a high speed grounding switch is improved while reducing the entire size and the production cost thereof.

摘要： A ground test switch comprises a terminal plate electrically connected to a movable contact member but electrically insulated from a closed vessel enclosing a high-voltage conductor, a grounding conductor disconnectably electrically connecting the terminal plate to a member maintained at ground potential, and a locking device locking the movable contact member against movement when the grounding conductor is detached from the connecting position. The operator may forget to mount the grounding conductor in the switch again after a ground test. Such a trouble can be readily detected because the movable contact member is locked against movement.

摘要： Electrical switchgear comprises a first contact set composed of a first contact which is pivotable about a pivot axis and a second contact, the contacts being relatively movable between a closed position wherein a load current can be passed therethrough and an open position. An arc is formed between the first contact and an arcing electrode during movement of the contacts from their closed to their open position, whereupon current flows through a field coil connected in series with the electrode to produce a magnetic field which causes the arc to rotate and become extinguished. The pivot axis of the first contact extends transversely to a major axis of the field coil such that, during opening of the contacts, an end portion of the first contact moves transversely to and inwardly of said major axis. A second contact set is operable to earth the first contact set when its contacts are in their open position. Both the first and second contact sets are disposed in a common housing which contains an electrically insulating fluid.
