Latching Technology used to Isolate Power Faults
TLX designs solenoids that solve our customers' unique dilemmas. This is an example of how TLX ingenuity was applied in the field.
A manufacturer of high-voltage electrical power distribution equipment needed a solution to actuate a fault-interrupting device. The solution would isolate power faults and reroute power when needed. If a fault was detected that could not be cleared immediately (e.g. a power line had fallen), a power interrupt switch in the fault-interrupting device turned-off electrical power in the affected section.
The system required a durable, fast solution that was stable in a wide range of temperatures. Furthermore, the component could only be manually reset once it was de-latched, eliminating the possibility of the power turning back on.
The manual reset latching solenoid designed by TLX used a permanent magnet to hold in the latched position while consuming no power. When the system detected a fault, a short pulse would de-latch the solenoid and interrupt the power. Robust design eliminated the durability failure modes exhibited by standard U-frame solenoids.
