摘要： The present disclosure makes it possible to reduce intervals between device units placed in a gas-insulated switchgear, thus achieving size reduction of the gas-insulated switchgear. A gas-insulated switchgear includes: a device housing having an operation door; a sealed container placed inside the device housing; and a circuit breaker unit and a ground switch unit attached to a side surface of the sealed container opposed to the operation door, via flange portions. A distance from the operation door to the side surface of the sealed container opposed to the operation door is different between a part where the circuit breaker unit is attached and a part where the ground switch unit is attached, so as to avoid interference between the circuit breaker unit and the ground switch unit.

摘要： A high-voltage connection system is described. The HV connection system includes a HV plug-connector and a HV socket-connector. The HV plug-connector is installed in an electrical HV unit to form an electrical connection between a second portion of a conductive core of the HV plug-connector and the electrical HV unit in a way that a plug extends outwards of the electrical HV unit. A HV cable with a cable lug is inserted in the HV socket-connector. One opening of the HV socket-connector is plugged on the plug of the HV plug-connector to align the conductive core with a center line of a second channel. An electric connection is created between the cable lug and the conductive core.

摘要： A grounding switch for grounding a high voltage cable in underground switchgear. The switch includes a solid insulation housing and a fixed electrode extending into one end of the housing and being encapsulated in the solid insulation housing. The switch also includes a ground electrode positioned at an opposite end of the housing from the fixed electrode, an air gap formed in the solid insulation housing between the fixed electrode and the ground electrode, and a movable electrode slidable positionable within the air gap to electrically connect and disconnect the fixed electrode to and from the ground electrode. An annular shielding electrode having a ridge is electrically coupled to the fixed electrode proximate the air gap, and shapes an electric field generated by the fixed electrode to be mostly confined within the solid insulation housing.
