摘要： Provision is made for a switch-state monitoring device that not only monitors the state of a switch but also prevents a motor burnout. A switch-state monitoring device for a switch that opens and closes a main circuit by use of a motor is provided with an operating time measuring unit for detecting an operating time for the motor when the switch is opened or closed; a first determination unit for comparing an operating time for the motor detected by the operating time measuring unit with an continuous-operating-capable setting time for the motor and determining whether or not the operating time for the motor has exceeded the continuous-operating-capable setting time; a protection device for halting energization of the motor in the case where, based on an output of the first determination unit, it is determined that the operating time for the motor has exceeded the continuous-operating-capable setting time.

摘要： 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.
