Manual Reset Latching Solenoid
A manufacturer of high-voltage electrical power distribution equipment and systems sought a solution to actuate a fault-interrupting device that would isolate power faults and reroute power when needed. The device contained a power interrupt switch that would turn off electrical power in a section if a fault was detected that could not be cleared immediately (i.e. a power line that had fallen down, etc.). The manufacturer needed a solution that would include a durable design, be stable in a wide range of temperatures, have a fast response time and could only be manually reset once it was de-latched. This would eliminate the possibility of the power being turned back on until the fault had been cleared.
It was determined that a manually reset latching solenoid was the best solution for this application. The latching solenoid held in a latched position with no power by utilizing a permanent magnet. When the system detected a fault, a short pulse was sent to the solenoid which would react immediately to de-latch and interrupt the power. This custom solenoid designed by TLX had an extremely robust design that eliminated the durability failure modes exhibited by a standard U-frame design. In addition, the solenoid was direct acting, temperature stable and had a fast response time.
For applications such as power interrupts, stand-by power systems, access and reclosure systems and heavy duty locks, this custom design can be configured to an application’s requirements.
