| 240 | Method for testing a latching solenoid of a switch and testing device for carrying out the method | US14608499 | 2015-01-29 | US10132866B2 | 2018-11-20 | Andreas Fischer; Stefan Widmann |
| A method is disclosed for testing a latching solenoid of a switch and a testing device for carrying out the method is disclosed. The switch includes a switching contact, formed by contact elements mechanically separated from one another when the switching contact is open; an electronic trip unit, to respectively monitor the current passing via the contact elements and test whether a current-dependent tripping condition is satisfied; and an actuator, to separate contact elements after actuation, the trip unit actuating the actuator via the latching solenoid when the tripping condition is satisfied; and an electrical energy store, to charge to a voltage before the tripping and to be discharged via the latching solenoid. After a period of time after the tripping, the voltage of the energy store is compared with a reference value and a fault signal is output if the voltage of the energy store is above the reference. | ||||||
