Abstract:
An enclosed switchboard includes: a device containing board which contains main circuit devices such as circuit breakers; and a cable connection board which is arranged side by side adjacently to the device containing board, and contains cables that input and output electric power to/from the main circuit devices. In the enclosed switchboard, the cable connection board is configured by one housing; and the inside of the housing is divided into two by a partition plate to be comparted to a cable lead-in compartment which contains lead-in side cables and a cable lead-out compartment which contains lead-out side cables.
Abstract:
A device for carrying high-voltage equipment in an electrically-insulated manner includes electrically non-conductive support insulators that are configured for mounting a carrier platform, which receives the high-voltage equipment, on a foundation in an electrically-insulated manner. Each support insulator extends towards the foundation from a bearing connected to the carrier platform. In order to provide such a device which is cost-effective and easy to produce, two support insulators extend at an incline from each bearing and the two support insulators form an acute angle with respect to their shared bearing.

Abstract:
A housing of a switchgear includes: a framework formed by joining vertical frames to depth directional frames and width directional frames, the vertical frames being arranged in a standing condition at four corners of a cuboid shape; at least a left and right pair of intermediate vertical frames each provided at an intermediate portion in the depth direction; and steel partition plates fixed over the whole in the vertical direction of the intermediate vertical frames, the partition plates being provided for separating the front and the back of the intermediate vertical frames. Then, the depth directional frame on the floor side is formed with a fixing hole near a lower portion of the intermediate vertical frame, the fixing hole being provided for fixing the housing to a foundation surface.
Abstract:
The invention relates to an arrangement with an earthquake-proof, pole-type or tower-type projecting component (1) of an industrial plant. It preferably relates to an arrangement for the protection of such a component (1) of a plant for generating, distributing or transforming electricity.The invention starts from an arrangement, in which the earthquake-proof component (1) in question is anchored via a foundation in ground or base (4) or is attached via a fastening element (3) to ground or base (4) or to another component of the plant. For earthquake protection according to the invention, only one vertically aligned screw-type spring (2) is disposed between the foundation or the fastening element and the earthquake-proof component (1). This is joined in a force-fitting and/or form-fitting manner with the foundation or fastening element (3) as well as with the axially lower end of earthquake-proof component (1), whereby the screw-type pressure spring (2) is loaded exclusively vertically and to bending, i.e., dynamically, in case of an earthquake.
Abstract:
An open frame-type electronic frame in which the two sides are each formed of two separate corrugated channel members rigidly connected by a series of cross struts having specially configured bent tang ends and heavy duty offset weld joints.
Abstract:
An equipment mounting rack is composed of a seismically sound skeleton structure having spaced vertical uprights supplemented by distinct spaced equipment mounting structures attached to that skeleton structure and extending along these vertical uprights and constituting side wall structures of a mounting rack interior space. The distinct spaced equipment mounting structures may have elongate first sections extending along the spaced vertical uprights, and elongate second sections extending along these first sections and constituting side wall structures of a mounting rack interior space. Cabinet walls may be attached to the skeleton structure, and the equipment mounting structures may constitute inside such cabinet walls side wall structures of a mounting rack interior space. The vertical uprights advantageously are reinforced by elongate partial enclosures that may avoid the need for a large number of weakening mounting holes in these uprights.
Abstract:
Relatively heavy electrical equipment, such as a computer mainframe or server unit, is provided with a mechanism which prevents and/or mitigates damage to the equipment caused by seismological or other activity. In particular, the mechanism comprises a turnbuckle having threaded yokes disposed at opposite ends of the turnbuckle together with eyebolts disposed within the yoke portions of the threaded yokes as a means for providing a retention device for anchoring relatively heavy computer and/or other equipment in position during seismological events. The electrical equipment is disposed within a frame which preferably includes a plurality of metal plates disposed at the bottom thereof. The frame is also provided with casters which permit the equipment to be rolled conveniently into place and then anchored firmly into position using a small number of pins which extend through the threaded yokes and eyebolts. There is provided an easily assemblable and economical apparatus which preferably includes a multiplicity of energy absorption points which help to prevent damage to the expensive computer frame and which further assists in maintaining computer operations at peak levels even during certain seismological activity.

Abstract:
A switchgear cabinet having a framework secured on a frame-like base. The framework has branches and is closed or closable by wall elements and at least one door. In order to design a switchgear cabinet that is as earthquake-proof as possible, a bottom side of the branches of a lower frame of the framework is connected by a plate-like damper frame to the top side of the base, which in turn may be fixed to a cabinet supporting surface.
