| 41 | High-speed mechanical change-over point | JP2001245151 | 2001-08-13 | JP2002117740A | 2002-04-19 | HOLAUS WALTER; SARTORI SAMUELE; STEURER MICHAEL; FROEHLICH KLAUS; KALTENEGGER KURT |
| PROBLEM TO BE SOLVED: To quickly open and close and reduce necessary energy. SOLUTION: A high or medium voltage switch is equipped with two contact members 1, 2; a rotating conductive bridging contact member 3; and a drive for moving the bridging contact member 3. When a change-over point is closed, the bridging contact member 3 is short-circuited with the fixed contact members 1, 2 and fit to between them. The drive is equipped with two coils 5, 6 surrounding the bridging contact member 3, and the bridging contact member 3 is arranged in a method capable of generating rotation with each one current of the coils. Energy necessary for rotating the bridging contact member is smaller than that of a contact member moving by the movement of a comparable change-over point. Therefore, energy requiring to open/close the change-over point is produced. COPYRIGHT: (C)2002,JPO | ||||||

| PURPOSE: A high-speed mechanical switching point is provided to quickly open and close and reduce energy required for opening and closing the switching point. CONSTITUTION: A switching point in a high- or medium-voltage switch contains two fixed contact members(1,2), a rotating, electrically conductive bridging contact member(3), and a drive for moving the bridging contact member(3). When the switching point is closed, the bridging contact member(3) is fit in between the fixed contact members(1,2) and short-circuits them. The drive is composed of two coils(5,6) which surround the bridging contact member(3) and are arranged in such a manner that the bridging contact member(3) can be caused to rotate by a current in a respective one of the coils. The energy which needs to be applied to rotate the bridging contact member is less than for contact members which move in translation in comparable switching points. | ||||||

| An electrical switchgear for fast limitation and interruption of fault currents includes a fixed electrode, a movable electrode having a contact portion and a repelling portion, a plurality of contact fingers, and a coil. The coil is arranged adjacent to the repelling portion to induce eddy currents therein, the coil and the fixed electrode being arranged on the same side of the movable electrode, and the repelling portion being movable relative to the coil. The coil has a first dimension between two of its opposite lateral ends and defines an area which corresponds to a majority of a surface area of the repelling portion. The repelling portion provides a continuous current path, having a dimension corresponding to the first dimension, for eddy currents induced by the coil, whereby the movable electrode is pivotally thrown in a direction away from the coil and the fixed electrode, thus providing a circuit trip. | ||||||

| The present invention is directed to an inductively driven electromagnetic linear actuator arrangement employing eddy currents induced by a fixed drive coil to drive its armature. Eddy current focusing fields are employed to direct the eddy currents using Lorentz forces to maximize armature speed. The armature includes a shorted driven coil in a DC magnetic field. This can be supplied by a permanent magnet. When current is applied, a force is felt by the coil in a direction perpendicular to the magnetic field. Such an actuator is well suited for electrical switching applications including transfer switching applications, circuit breaker applications, and ground fault interrupter applications. | ||||||

| An electromagnetic actuator is capable of providing a high speed driving force, for example, for driving the contacts of a circuit breaker or similar power distribution equipment. The electromagnetic actuator may use a directly powered moving coil element in combination with one or more energized stationary coils to generate an output force using reduced requirements for current, voltage and current/voltage rate-of-change. Precise control of actuator motion is obtained by permitting different supply voltages, firing times and capacitor supplies. The electromagnetic actuator may further incorporate a return spring arrangement and a magnetic latch arrangement. | ||||||

| The switching point in a high or medium voltage switch contains two stationary switch pieces which are of cylindrical design and led coaxially into one another, to form an annular gap. A movable bridge switch piece constructed in the form of a contact ring fits into the annular gap when the switching point is closed. An electrodynamic drive comprising two coils moves the contact ring in the axial direction. By virtue of the low mass of the contact ring, the single moving part of the switching point can be switched on and off very quickly and efficiently. | ||||||
| 57 | Circuit breakers with PTC (Positive Temperature Coefficient resistivity | US918768 | 1997-08-25 | US5886860A | 1999-03-23 | William Weizhong Chen; Colin Cornhill; Andy Haun; Gary Scott; Manzoor Ali; William Rezac; Kevin James Green |
| A Positive Temperature Coefficient Resistivity (PTC) element has a resistivity that increases as the temperature increases. Circuit breakers having PTC elements can achieve better overload and short circuit protection than existing products. Breakers with PTC elements can also be combined with ground fault detection circuits to activate the circuit breaker under ground fault conditions that are less severe than the overcurrent conditions that would normally activate the circuit breaker. A shunt trip assembly incorporating a PTC resistor reduces the required power rating of the clearing switch. | ||||||
