Achieve Immediate Response in a Fault-Interrupting Device
These large latching solenoids with high latching force were designed for a manufacturer of high-voltage power distribution equipment to disconnect power quickly to prevent equipment damage.
A manufacturer of high-voltage power distribution equipment needed to actuate a fault-interrupting device while switching functions in their high-voltage equipment. This device would disconnect power if a fault could not be cleared immediately or maintenance needed to be performed.
In order to avoid equipment damage, the actuation solution needed to be durable with a high latching force to actuate immediately, allowing the power to disconnect quickly.
The TLX Solution
We designed several large latching solenoids that have a high latching force ranging from 100-300 lbs. These heavy-duty solenoids used residual magnetism, not constant power, to hold the latched position. When the system detects a fault, a short pulse of power causes the solenoid to de-latch, activating the fault interrupter. Once maintenance is complete or the fault is cleared, another short pulse of opposite polarity causes the solenoid to re-latch. This solenoid is direct-acting and temperature stable with a fast response time.
