| PROBLEM TO BE SOLVED: To provide a means reducing the fatigue of a contact in a rotary contact circuit breaker over a wide range of ampere rating, using the minimum number of related assembly components. SOLUTION: A circuit breaker rotary arm 26 for moving contacts 29, 30 is used within a plurality of single circuit breakers 11, 12, 13 linked so as to form one multipole circuit breaker 10. In order to make the fatigue of the contact uniform among related circuit breaker contacts 27, 28, 29, 30, a groove hole is formed in a rotor 25 supporting a pivot of the rotary contact arm 26, the constant contact compression force is kept, and at the same time so as to allow the shape change of the contacts 27, 28, 29, 30, a rotary arm 20 supporting the moving contacts 29, 30 is automatically positioned. Each of circuit breakers 11, 12, 13 is connected to a central operating mechanism 18 with one pin 38. COPYRIGHT: (C)1999,JPO | ||||||

| PURPOSE: To make an electromagnetic switch compact and to reduce the number of its part items by enabling first and second arms to rock about their respective support points, and connecting the free end of the first arm to an armature which has an operating member working on the second arm. CONSTITUTION: A first arm 15 passes through a gap in a stator plate 11 along the leg 4 of a stator main body 3, and an armature 7 can project outside by way of the leg 4. The free end 19 of the arm 15 is shaped so that it can be coupled to the armature 7 in the form of a hinge. The second arm 16 also passes through a gap in the stator plate 11 along the leg 5 of the stator main body 3, and a pin 8 coupled to the armature can project outside through the leg 5. The arm 16 has a movable contact 24, which takes the form of, e.g. a conductive layer 22 covering the free end 21 of the second arm 16 and facing a fixed contact 23 and its end at the side of the arm 16 facing the stator main body 3. Therefore, a switch can be made compact and the number of its part items can be reduced. COPYRIGHT: (C)1989,JPO | ||||||

| A current assignment method and a switch arrangement are disclosed for assigning current, the switch arrangement including two series-connected switches, each including a trigger unit to check whether a preset current condition is satisfied. A signal is sent by the trigger unit of a switch which is postpositionally placed when the current condition is satisfied, the signal at least preventing the immediate triggering of a correspondingly prepositionally placed switch after being received by the corresponding trigger unit. To achieve a technically simple communication connection between switches, in at least one embodiment each trigger unit is formed so as to send but and receive the signal, and each trigger unit includes a measurement unit for measuring an energy flow direction in a subordinate switch and a conversion unit for converting from sending to receiving or from receiving to sending appropriately when the energy flow direction is reversed. | ||||||

| 53 | Circuit breaker for hierarchically controlling short-circuit current and trips | US15233949 | 2016-08-10 | US09633811B2 | 2017-04-25 | Xin Li; Bochen Li; Bolin Li |
| The invention discloses a short circuit current hierarchical control tripping parameter circuit breaker. According to the invention, resistance of an alloy magnetic resistance body is changed through circuit current, and contract control can be carried out on short-circuit current. The control range of the circuit breaker can achieve that no magnetic resistance will be generated when current is no more than 8 times of rated operational current, and current limiting may be realized by the magnetic resistance when current is 8 times more than rated value. In this way, hierarchical control on short-circuit current of different levels of circuits can be carried out, and short-circuit current can be limited in a predetermined range, thereby restricting the short-circuit current in a predetermined range, solving a problem of power supply flickering, and avoiding large-area power failure accidents caused by override trip existing in an electrical control switch. | ||||||

Each of the predetermined current conditions is greater than an arc reduction maintenance current condition of four times the maximum rated current of the trip mechanism. An instantaneous trip circuit cooperates with the current transformer and the manually operable selector to compare the signal representative of the current with respect to the selected one of the predetermined current conditions. The instantaneous trip circuit responsively causes the operating mechanism to instantaneously trip open the contacts. | ||||||
