| 62 | METHOD FOR EVALUATING THE MECHANICAL PERFORMANCES OF A SWITCHGEAR DEVICE AND SWITCHGEAR DEVICE FOR IMPLEMENTATION OF SAID METHOD | US14022974 | 2013-09-10 | US20140069784A1 | 2014-03-13 | Francois CAZALS |
| The invention relates to a method for evaluating the mechanical performances of a switchgear device comprising at least one pole. Each pole comprises: a pair of contacts (12, 14); a support arm (16) for a first contact (14); a mechanism (22) for driving the support arm (16) comprising a rotary poles shaft (20) and energy accumulation means capable of driving a movement of the said arm in order to place the contacts (12, 14) in an open position. The method consists in: measuring the angle of rotation (θ) of the poles shaft (20) over a period of opening the contacts (12, 14); retrieving from the measurements at least one specific value; comparing the said specific value with specific initial operational specifications of the switchgear device; diagnosing the mechanical wear performances of the drive mechanism (22) as a function of a comparative state between the specific values obtained and those of the operational specifications. | ||||||

| 68 | Evaluation of the integrity of depressed contacts by variation of the rotation of the pole-shaft | US12662647 | 2010-04-27 | US20100288606A1 | 2010-11-18 | Marc Rival |
| A device for measuring the wear of the contacts of a switchgear device is described. The switchgear device is of the open circuit breaker type with offset pole-shaft, and the movable contact is mounted on a sliding support. Measurement of the wear of the contacts is based on evaluation of the over-travel of the movable contact in the closed position when the latter slides in its support. This over-travel is determined by measuring the residual rotation of the pole-shaft, preferably by a contact-less magnetic rotation sensor. | ||||||

| 72 | Low-voltage power circuit breaker having an electronic overcurrent release and an operating-state detection device | US11070241 | 2005-03-03 | US20050195548A1 | 2005-09-08 | Andreas Pancke; Wolfgang Roehl; Manfred Schiller |
| A low-voltage power circuit breaker includes an electronic overcurrent release, which draws its operating energy from the power supply system monitored by the low-voltage power circuit breaker, and an operating-state detection device. Since it is possible for the power circuit breaker to switch to a short circuit on connection, it may be appropriate for no undelayed tripping of the power circuit breaker to be permitted directly after connection, or for the tripping time for the delayed tripping to be altered. Provision is made for the operating-state detection device to be a device for detecting a connection operation, whose output signal is fed to the overcurrent release, which sets a different disconnection time for the low-voltage power circuit breaker at the beginning of a connection operation for a predetermined period of time. | ||||||
| 73 | Non-contact auxiliary switch and electric power apparatus incorporating same | US10335664 | 2003-01-02 | US20040130217A1 | 2004-07-08 | Peter K. Moldovan; Edward L. Wellner; Michael R. Larsen; Paul J. Rollmann; Xin Zhou; John R. Skibinski; Randal D. Gazdecki |
| The auxiliary switch includes a non-contact sensor, such as a Hall effect device, that is switched by the condition of a magnetic field. The magnetic field condition is effected by a movable contact indicator that moves between open and closed positions with the separable contacts of the electric power apparatus. A magnet may be attached to the movable contact indicator, or the movable contact indicator can be magnetized to form the magnet. Alternatively, the moving contact indicator can intercept or not intercept a magnetic field produced by a fixed magnet spaced from the sensor. The Hall effect device may be mounted on the outside of the nonmagnetically permeable housing of the electric power apparatus, or inside if there is sufficient room. In either case, no mechanical coupling is required for the sensor. | ||||||
| 74 | Method of monitoring state parameters in a switching device, and associated device | US09541723 | 2000-04-03 | US06400547B1 | 2002-06-04 | Fritz Pohl |
| A method of monitoring state parameters in a switching device records and evaluates sensor signals of sensors which are susceptible to an interference caused by external electrical or magnetic fields. A temporal sequence of the sensor signals is evaluated by determining whether the sensor signals are disturbed or undisturbed. The interference in the sensor signals is suppressed by generating evaluation signals which correspond to the undisturbed signals. A device for monitoring state parameters of a switching device includes sensors for recording sensor signals and includes a passive interference suppression device and an active interference suppression device for suppressing the interference. | ||||||

The support can be glued onto the front panel (2), which need have no openings. Elements (14, 15, 16, 17) are in the top part for causing an indirect control transmission through the front panel, with sensors (5, 6, 7, 8, 9, 21, 22) behind the front panel (2) electrically sensing the indirect control transmissions and carrying out operational functions of the electrical appliance. | ||||||
| 77 | Bimetal controlled circuit breaker | US33591 | 1993-03-19 | US5432491A | 1995-07-11 | Josef Peter; Peter Meckler; Fritz Krasser; Gerhard Endner |
| A bimetal controlled circuit breaker includes a current bus that is electrically connected in series with the bimetal element. The current bus extends parallel to the bimetal element in the deflection plane of the latter and is rigid relative to the bimetal element. The deflection of the bimetal element is supported by the action of electrodynamic forces. In order for the circuit breaker to be suitable for greater current intensities and the effect of the electrodynamic forces to be better utilized, the bimetal element is electrically connected in parallel with a shunt path. | ||||||
| 78 | Earth leakage trip indicator | US584975 | 1990-09-19 | US5089796A | 1992-02-18 | Oliver Glennon; James Shortt |
| A residual current circuit breaker 1 has a partition wall 3 which separates an over-current protection device 4 from a residual current detection circuit 5. A plunger rod 24 extends through a bore 23 in the armature 21 of a coil 20 and is moved independently through the coil 20 to trip the breaker if a residual current is detected by the circuit 5. The plunger rod 24 is moved by a drive rod 31, the operation of which is controlled by a permanent magnet which retains the drive rod 31 retracted and an electromagnet which allows the drive rod 31 to drive forwardly under the action of a spring 32 in the event of a residual current being detected. The plunger rod 30 is reset by a reset lever 40 which is moved when an operating handle 18 of the breaker moves from a non-tripped to a tripped position upon tripping of the breaker. | ||||||
