摘要： PROBLEM TO BE SOLVED: To provide a gas insulated switchgear that enables reduction of gas processing work inside a plant and in the field, simplify the work and reduce the processes. SOLUTION: In connecting a container 101 to another container 102, a (plug-in type) spherical conductor 103 that can automatically be connected is fixed in contact with a contact maker 102f, the container 101 is brought close to the container 102, and the conductor 103 is jointed to 101f. Before connection, a valve 108 contact a central conductor 102e by the spring 109. When the container 101 is brought closer to the container 102, the tip of the valve 108 contact the central conductor 102e. Then, the spring 109 is contracted, and the valve 108 separates from the central conductor 102e, which makes a high-pressure insulating gas inside the container 102 push air in to a joint part 107 towards the outside of the container out of an opening provided in the central conductor 102e, so that the joint part 107 is filled with the insulating gas.

摘要： PROBLEM TO BE SOLVED: To scale down the width and height of a device at large by accommodating an earth switch, a disconnector for an arrestor, an arrestor, and a disconnector in a power receiving container, and providing a cable head on one side of this power receiving container, and connecting the disconnector to the other side thereby forming a power receiving unit. SOLUTION: The primary apparatus of a disconnector, that a detector 3, an earth switch 4, a disconnector 5 for an arrestor, an arrestor 6, a disconnector 7, and an earth switch 8 are all accommodated in one power receiving container 18, and it is arranged in the space under the unit which has accommodated the secondary apparatus of a breaker. A T-shaped cable head 2 is provided next to the power receiving container 18, and a current transformer 1 is installed in the space under this, and also a storage container for a breaker is connected to the side of the breaker 7 of the power receiving container 18. Further, a disconnector 5 for an arrestor is composed of an earth switch fitted with a three-position type disconnector, and a cutoff device for the arrestor 6 also has a function of disconnecting the earth switch 4. Hereby, the number of containers of power receiving units is reduced, and the width and the height of the device at large are scaled down, and the number of operation mechanisms and operation tools can be reduced.

摘要： PURPOSE:To improve the reliability of failure diagnosis at the time of occurance of abnormality and at the time of periodical inspection by independently arranging a gas pressure monitoring circuit in each gas section and making it possible to judge the generation of a fault in each sensor circuit. CONSTITUTION:The gas pressure value of respective plural divided gas sections A to C is converted into transmission signal by respective pressure sensors 3 and the signal is transmitted to respective temperature compensating arithmetic circuits 7. The circuit 7 compares the transmitted signal with a measuring signal outputted from an atmospheric temperature sensor 11 and sends converted pressure signal to a central monitoring device. On the other hand, each comparator 8 compares the converted pressure signal with a judging level, and when abnormality is continued for a prescribed time, the comparator 8 outputs an alarm through an alarm relay 10. Respective switches 4, 5, 15 are arranged to provided respective separated sections or judge the cause of faults. Consequently fault diagnosis can be executed at each unit or a failure section can be restricted when the abnormality of gas pressure is generated or periodical inspection is executed and the reliability of the monitoring device can be improved.

摘要： PURPOSE:To provide an omnidirectinally adaptable type operating device which is constructed so as to decrease the number of normally sealed places of both a pilot valve and a charging valve while being adaptable to arranging the charging valve in any such directions as two directions given by the fore-and-aft movements of an operating valve but also as the top-and-bottom and horizontal directions of the operating valve. CONSTITUTION:A pilot valve is connected on its normally charging chamber-side to the valve rod of a charging valve 5 having two mutually different-diameter blades on the small-diameter blade-side of the rod, and then connected on its normally uncharging chamber-side to the valve rod on the large-diameter blade- side thereof. An omnidirectionally adaptable type compact operating device for a breaker can be provided by constructing the charging valve 5 in such a manner that it may be adapted to its arrangement in any of such directions as to be positioned in front of or in rear of an operating valve 1 in the axial direction thereof but also as the top-and-bottom and horizontal directions of the operating value 1.

摘要： PURPOSE:To provide a receiving/transforming facility for a consumer, which can be constituted inside the orderly site even if the number of a series of panels of MCS increases and can make the most of land effectively. CONSTITUTION:TRs 2a and 2b are arranged next GIS 40, and MCSs 3a and 3b are arranged next to these TRs 2a and 2b on the opposite side, and MCSs 3a and 3b are ones where each MCS unit is arranged in the juxtapositional direction of GIS 40 and TRs 2a and 2b to constitute a series of panels, and these are arranged in opposition in the direction orthogonal to the above- mentioned juxtapositional direction, being divided in two. Therefore, MCSs 3a and 3b can be constituted in the same width dimensions WG as GIS 40, and besides even if the feeders of MCS 3a and 3b increase, these can be installed on the site orderly without increasing this width dimension.

摘要： PURPOSE:To obtain a circuit breaker operating device of large spring force, high voltage, and large capacity by providing a connecting mechanism that includes both an abutting connecting portion which puts an energy storage shaft in a turning movement in the direction in which a closing spring is pushed by the turning movement of a drive member caused by a driving device and a non-connecting portion which puts the energy storage shaft in a turning movement through the release of a locking device while not in connection with the drive member. CONSTITUTION:A connecting mechanism 14 is formed in a portion where an energy storage shaft 15 to which a closing spring 5 is connected and a drive member which is disposed on almost the same axis as the energy storage shaft 15 and to which a driving device 38 for providing a force to push the closing spring is connected are opposite to each other. The connecting mechanism 14 is provided with both an abutting connecting portion which puts the energy storage shaft 15 in a turning movement in the direction in which the closing spring 5 is pressed by the turning movement of the drive member caused by the driving device 38 and a non-connecting member which puts the energy storage shaft 15 in a turning movement through the release of a locking device 37 while not in connection with the drive member. Sufficient mechanical strength can thus be obtained even with reduction of the diameter of the connecting mechanism 14 and the spring force of the closing spring can be increased using a small connecting mechanism.
