摘要： PROBLEM TO BE SOLVED: To expand the equipment without impairing the respective characteristics by providing the first and second transmission lines between switch gears when an operation-interlocking type existing switch gear device and self-completing type switch gears on the side of expansion are combined. SOLUTION: The first and second transmission paths are provided between an operation interlocking type switch gear device A and self-completing type switch gears 18b-18n. At a one specified switch gear 1a of the switch gear device A, a common operating means on the side of expansion is provided together with a common alarming means and a common operating means on the side of the device. Thus, the alarming of the fault of the entire equipment including the switching gears 18b-18n on the side of expansion and the display of the alarm and the stopping operation of the alarm can be performed at one place (switch gear 1a). Even at the switch gears 18b-18n on the side of expansion, the display of the fault and the stopping of the alarm can be performed by the respective operation. As a result, the expansion of the scale of the equipment and the like can be achieved without impairing the characteristics of both parts.

摘要： PURPOSE:To improve arc extinguishing performance upon occurrence of ground fault by constituting an enclosed container with a resistor mainly composed of epichlorhydrin rubber containing no additive and a good conductor applied onto the inner and outer faces of the resistor. CONSTITUTION:An iron plate having thickness of 2.3mm, for example, is employed as an outside good conductor 4 and a conductive paint film is employed as an inside good conductor 3. A copper rod having diameter of 50mm is employed as a central insertion conductor 1. A rubber composition sheet having thickness of 5mm is applied onto the inner face of the outside good conductor 4 (duct), then the resistor 2 is heated for an hour under the temperature of 150 deg.C thus vulcanizing the rubber composition. The inside good conductor 3 is formed by applying conductive paint. By such arrangement, arc is extinguished quickly upon reset of the conductor application voltage to a normal level even when an abnormal voltage is applied onto the conductor and different phase ground-fault current is produced.
