摘要： A gas insulated electrical apparatus comprising a hermetic sheath filled with an electrically insulating gas having a plurality of electrically conductive sheath sections including hermetically fastened flanged ends. A high voltage conductor is electrically insulatably supported within the sheath by an electrically insulating spacer which is hermetically and securely held at its outer periphery between the flanged ends of the sheath sections. An electrically conductive trap ring is inserted between at least one of the flanged ends of the sheath sections and the outer periphery of the spacer. The trap ring defines, between the trap ring and the spacer, a low electric field particle trap in which a low electric field is formed and in which electrically conductive particles can be trapped and retained.

摘要： An encased gas-insulated high-tension line is disclosed especially for regions of the line where disturbing arcs can occur so as to melt a grounding casing of the line. A heat and pressure resistant insulative layer prevents an escape of hot and possibly poisonous insulating gases from the casing in the event of a casing melting. The insulative layer is preferably made of an epoxy resin/glass fiber fabric and is wound around arc-endangered areas at fixed arc regions. An additional heat-resistant insertion may be included between the casing and the insulative layer.

摘要： Devices, systems and methods are provided to improve communication of switch sensor and status signals between a medium voltage overheard switchgear and an intelligent electronic device (IED). A switchgear interface device is deployed proximally to a switchgear and/or junction box situated at a distal end of a utility pole. The switchgear interface device (SID) receives, processes and combines sensor signals and status signals from switches in the switchgear with metadata for transport as digital signals to an IED mounted at the other end of the utility pole. The cabling for sensor and status signals between the SID and the IED can be fiber or Ethernet. The digital signals can be formatted using the IEC61850 standard. The SID can have drive electronics and send open and close command signals to the switches to eliminate the need for a multi-pin connector cable for transport of switch power signals from the IED.

摘要： Provided is a gas-insulated switchgear having a circuit breaker tank with a reduced size. The gas-insulated switchgear includes: a connection conductor connected to two or more power cables, for each phase, inside the circuit breaker tank; a solid-insulated bus placed outside the circuit breaker tank and connected to the connection conductor via a connection bushing; and an instrument current transformer attached to the solid-insulated bus.

摘要： A gas insulated apparatus includes: a grounded metal tank in which an insulating gas is enclosed; a conductor disposed in the tank, voltage being applied to the conductor; and a non-linear resistance layer disposed on at least part of an inner surface of the tank and made from an insulating material containing a particle of a non-linear resistance material, the non-linear resistance material being conductive when voltage higher than or equal to a threshold is applied. The non-linear resistance layer has a thickness that is larger than a sum of a thickness of a conductive portion and a particle diameter of the non-linear resistance material, the conductive portion being a portion of the non-linear resistance layer that is conductive when voltage higher than or equal to the threshold is applied to a metal foreign object on the non-linear resistance layer.

摘要： A switchgear exhaust assembly for controlling flow of exhaust from exhaust ports of a switchgear has an enclosure that is couplable to the switchgear to substantially enclose the exhaust ports. The enclosure defines a primary exhaust chamber for receiving exhaust flowing through the exhaust ports and allowing gases of the exhaust to expand and cool down. A top wall of the enclosure has a top layer and a bottom layer defining at least one secondary exhaust chamber. The bottom layer has openings whereby exhaust in the primary exhaust chamber flows to the secondary exhaust chamber. The top and bottom layers further define one or more side openings that provide fluid communication between the secondary exhaust chamber and a space surrounding the enclosure, thereby allowing exhaust to be expelled into the space.

摘要： An electrical apparatus containing an adsorbent, includes a housing, an adsorbent cover, an adsorbent and a locating bolt. The housing is cylindrical and has at least one locating hole. The adsorbent cover is installed in the housing, and has an annular groove in a circumferential direction, with the locating hole being opposite the groove. An outer diameter of a groove edge is the same as an inner diameter of the housing, while the diameter of a middle part of the groove is less than the inner diameter of the housing. The adsorbent is placed in the groove. The locating bolt passes through the locating hole and extends into the groove. The electrical apparatus has a simple structure. Since installation on a flange is not needed, a flange on the housing that is connected to an adsorbent container is dispensed with. The cost of the adsorbent container and housing are reduced.
