摘要： A high speed fault diverter switch is connected near the input side of a gas-insulated substation. The switch is normally open and is used in response to arcing anywhere within the substation to connect the gas-insulated high-voltage conductor to ground for each phase of the system at high speed to divert the fault current to ground.

摘要： The invention relates to an indicator and/or interrupter circuit for an electrical capacitor. On the build-up of internal pressure in the capacitor a switch is caused to operate to open a set of contacts which thereby energizes an indicating lamp to provide a visual indication of a failed or over-pressure condition in the capacitor. The opening of the switch may also cause an interruption of current flow through a holding coil and this current interruption causes a circuit interrupter to operate mechanically and thereby remove the capacitor from its circuit.

摘要： An explosion-proof device includes a frame having a hollow shape, the frame housing an electrical component and a battery capable of supplying the electrical component with electric power. A protection device is configured to stop electric supply to the electrical component from the battery, if there is a risk of an explosive atmosphere entering the frame. The battery is housed in an explosion-proof container, within the frame, and thus it is possible to suppress damage to surroundings effectively even in case of ignition of an explosive atmosphere flowing into the frame by the battery.
