Page 26: Operation
Operation Understanding Trip-Free Operation The stored-energy mechanism has an instantaneous trip-free capability. If the Series 2000 Circuit-Switcher is closed into a fault sensed by the user-furnished relaying, the mechanism will immediately trip. To accomplish trip-free operation, the stored-energy mechanism uses two spring assemblies: one for closing and one for opening. -
Page 27: Manual Operation
Operation Manual Operation To trip the interrupters, push the manual TRIP lever counterclockwise as indicated by the TRIP lever label. See Figure 16 on page 20. The opening latch in the stored-energy mechanism will release, discharging the opening spring. This action trips the interrupters and forces the opening and closing pistons in the mechanism downward, as denoted by movement of the indicator to the DISCHARGED indicator window. -
Page 28: Understanding The Gas-Pressure
Operation Understanding the Gas-Pressure Indicator and Safety Relief Device Safety relief device Safety relief device Gas-pressure indicator Gas-pressure indicator Series 2000 Circuit-Switchers have sealed interrupters containing gas under pressure. Loss of gas pressure may result in improper interrupting action. Low gas pressure is signaled by a red target in the GAS PRESSURE indicator at the upper terminal end of the interrupter.
