Abstract:
PROBLEM TO BE SOLVED: To provide the gas-insulated switch gear arrangement having substantially the more functionality and flexibility. SOLUTION: A disconnector unit is provided with a first fixed contact connected to a first terminal and a first movable contact interrupted with the first fixed contact. A circuit breaker unit is provided with two interrupting contacts operated between closed/opened positions. A second casing is connected to the disconnector unit, a circuit breaker unit operating means, and the operating means. The second casing receives the interrupting contact to mount in its outer side surface the first movable contact, in the case of operating the disconnector unit. The first movable contact in a manner of rotating is turnably mounted in a first casing. The two interrupting contacts are electrically connected to the closed position of a circuit breaker to be connected to the operating means in a manner as held still with each other during rotation of the second casing.

PROBLEM TO BE SOLVED: To provide a compact current transformer for the gas-insulated switch gear. SOLUTION: The current transformer (1') has a mounting flange (12, 12') detachable relating to an installation opening (3c) of a core supporter (11) for an integrated current transformer core (2). The mounting flange is detachable as the two pieces divided type fastening flange (12) or as the integrated rotational flange (12') insertably mounted in the installation opening (3c), and is constituted in a manner of diametrically expanding a mounting space for the integrated current transformer core (2), reducing the diameter (d) of the integrated current transformer core (2), and contracting the mounting area of a current transformer casing (11a).

Abstract:
PROBLEM TO BE SOLVED: To provide a curable epoxy resin composition with improved physical and mechanical properties, and to provide a method for two-dimensional fabrication of a heat cured shaped articles in a short time. SOLUTION: The invention relates to the curable epoxy resin composition comprising: a polyepoxide; an anhydride hardener; a 1-substituted imidazole as catalyst; at least a diol; a filler; optionally additives. Wherein the polyepoxide is obtained by reacting an epihalohydrin with bisphenol A or bisphenol F, the anhydride hardener is a phthalic anhydride compound, and the diol is a compound selected from bisphenol A or a polyalkylene glycol and the diol is present in an amount of from 5 to 50 phr of said polyepoxide.
