Gas-insulated switchgear

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.

Test module for motor control center subunit

A system and method are provided for coordinating the installation and removal a motor control center subunit with the power connection and interruption thereof. A system of interlocks and indicators causes an operator to install a motor control center subunit into a motor control center, and connect supply and control power thereto, in a particular order. Once installed, a test module system included with the subunit provides for pass-through connection of signals from equipment test points. The test module can thus relay internal conditions of the subunit to the operator without a need for disengaging or opening the subunit.
