An interrupter switch mechanism , an actuator mechanism for operating the switch mechanism , an engagement arm such as a whip, a first resistor , a second resistor , a drive mechanism for pivoting the engagement arm into contact with the resistors and , and a drive shaft . The drive mechanism has a first hub , a second hub that is biased relative to the first hub , and a pivotal latch member that is biased towards an engaged position with the second hub . The drive shaft sequentially operates the drive mechanism to introduce the first resistor and then the second resistor , and then operates the actuator to close the switch mechanism , for reducing electrical disturbances when switching a capacitor bank into an electric power circuit

Capacitor switch with external resistor and insertion whip

An actuator mechanism that decreases the time needed to move the contacts of a circuit interrupter between a closed circuit position and an open circuit position to reduce the probability of the occurrence of restrikes. The actuator mechanism uses a toggle spring arrangement that uses a single spring to move the interrupter through both an opening stroke and a closing stroke. The interrupter is designed to connect to the circuit in parallel, so that the interrupter is not normally in the circuit when the circuit is closed. Because the interrupter is not normally in the circuit, it can be manufactured to less stringent standards than those that apply to electrical components that normally remain in the circuit. The interrupter is well adapted for use as a puffer-type interrupter in which the contacts of the interrupter are contained in an arc-extinguishing gas, such as sulphur-hexaflouride (SF ) gas to further reduce the probability of restrikes and to minimize the effect of occurring restrikes. The interrupter has a bellows arrangement that provides a seal to contain the sulphur-hexaflouride (SF ) gas while allowing the actuator mechanism to freely operate without deterioration of interrupter components. The bellows arrangement enables the interrupter to be utilized in capacitor switching applications in which frequent switching is required. The interrupter may also include a voltage-clamping device connected in parallel across the contacts of the circuit interrupter.
