An anti-deformation structure is formed on the surface of a flexible plate-shaped part. The anti-deformation structure includes protrusions and depressions formed on the surface of the plate-shaped part. The protrusions and depressions has a shape in which adjacent protrusions become in contact with each other in the state when the plate-shaped part is deformed within a range of elastic deformation, restricting further greater deformation, and thus, preventing excessive deformation leading to permanent deformation and raising the resistance to the stress. The flexible base material can be applied to flexible image-displaying devices.

Power-station installations according to the invention can advantageously be combined to form modular power-station centers, which advantageously have common voltage rails and media rails.

The present invention relates generally to a switchgear apparatus. More particularly, the invention encompasses a mounting base with arc plenum for a switchgear apparatus. The present invention also relates to enclosures for switchgear, panel boards, circuit breakers, and more particularly to an enclosure for low voltage switchgear and switchboard assemblies. The enclosure can be a walk-in type enclosure or a non-walk-in type enclosure. This invention further provides a method and apparatus for channeling plasma (hot arc gasses) that are generated from an arc. The switchgear mounting base with internal arc plenum can be an integral part of an arc resistant switchgear assembly and is preferably located under the switchgear. The switchgear mounting base works in conjunction with a ventilation system in the switchgear apparatus to channel hot arc gasses (plasma) from the lower breaker compartments in the front of the switchgear in the event of an internal arcing fault in one of the breaker compartments. The hot arc gasses exit downward from the bottom of the switchgear and into the plenum. The gasses then are channeled to travel backward through the plenum and then up again into the switchgear rear compartment where they can be routed to and safely discharged from the roof of the switchgear apparatus.

An arc resistant switchgear assembly is provided having a front wall, a rear wall, a bottom surface, an upper surface, a first side wall, and a second side wall opposed to the first side wall and spaced a first distance from the first side wall, with each of the first and second side walls having an upper portion and a lower portion, and with each of the first and second side walls having an inner and an outer surface, with at least the lower portion of both the first side wall and the second side wall having at least one blow-off panel detachably secured thereto by fastening means. Each of the panels is detachably secured to the outer surface of the side wall to which each is secured. The assembly has a vertical plenum formed directly adjacent both the first and the second side walls, with the outer surface of each of the first and second side walls defining an inner side wall of each of the vertical plenums. The outer surface of the first side wall defines the inner side wall of one of the vertical plenums and the outer surface of the second side wall defines the inner side wall of an adjacent vertical plenum.

A seal apparatus is disposed between a switchgear cabinet and a circuit breaker between the racked and unracked positions of the circuit breaker.

Power converters such as power modules configured as inverters employ modularized approaches. In some aspects, semiconductor devices are thermally coupled directly to thermally conductive substrates without intervening dielectric or insulative structures. Additionally, or alternatively, semiconductor devices are thermally coupled to thermally conductive substrates with relatively large surface areas before heat transferred from the semiconductor devices encounters a dielectric or electrically insulating structure with correspondingly high thermal impedance.

For simple structure and easy manufacture, module tanks have a common standardized size so that the same tank is applicable even when the components to be accommodated are changed. The basic structure of the module is arranged so that all of the interrupter, the disconnector with the grounding switch, the bus bar bushing, the cable connecting bushing and the gas section spacer can be mounted, and necessary main circuit components depending upon the circuit to be used are left behind and unnecessary main circuit components are short-circuited by a short-circuiting conductor, and that the tank opening portions are either left un-worked during manufacture or closed by a cover. The bus bar bushings and the cable connecting bushings are attached at the rear face of the tank and the gas section spacer is disposed on the top or bottom face of the tank. A lightning arrester in lieu of interrupter may be accommodated within an insulating cylinder housing the main circuit of the interrupter.
