142 Method of establishing the residual useful life of contacts in switchgear and associated arrangement US09117630 1998-03-03 US06225807B1 2001-05-01 Fritz Pohl
To determine the remaining lifetime of contactor contacts, the contact spring action at the gap is determined as a substitute criterion for contact erosion, and to determine the erosion of the contacts, the change in spring action during a shutdown cycle is measured and converted to remaining lifetime. With a yoke and armature solenoid actuator with a solenoid, the armature path from the start of the armature movement to the start of contact opening must be measured. The time of separation of the armature from the yoke of the contactor solenoid actuator is determined from the voltage on the solenoid. The increase in magnetic resistance of the magnetic circuit when the magnetic armature is raised is determined. In the respective arrangement with an analyzing unit for determination and display of the remaining lifetime, the analyzing unit has means for detecting and measuring the voltage on the solenoid.

A circuit breaker includes at least one coil for measuring electric current of an electrical conductor of an electrical circuit, connected to a control unit which compares the measured current or its equivalent with a first current limit value. Upon the first current limit value being exceeded, the control unit initiates an interruption of the electrical circuit. The two terminals of the coil are connected via a series circuit which has a first switch opened in its basic state, a voltage source and a voltage indicator. The control unit is designed such that, when a second current limit value is undercut and a first period of time is exceeded, the first switch is closed for a second period of time, the voltage indicator compares the voltage present with a first voltage value and, when the latter is exceeded, delivers information on the absence of faults of the coil.
