摘要： A CIRCUIT INTERRUPTER HAVING AN INSULATED BRIDGING CONTACT A circuit interrupter particularly suitable for use in an oil filled distribution transformer having an elongated contact arm pivotable about one end with a movable contact attached to the other end through a suitable insulating members to electrically isolate the movable contact from the elongated contact arm. The movable contact is a bridging contact for completing a series circuit through two stationary contacts. The movable bridging contact is spring biased away from the elongated contact arm. A retainer restricts the movement of the bridging contact away from the insulating members attached to the elongated contact arm. The biasing spring is disposed between the insulating members and the retainer. Grooves formed in the sides of the insulating members restrict rotational movement of the retainer and bridging contact. For larger circuit interrupters, a bridging contact assembly can be utilized having a plurality of parallel bridging contacts and a plurality of biasing springs. The elongated contact arm is biased towards an open position when the bridging contact is separate from the stationary contacts, but with the circuit interrupter in the normally closed position is held in a closed position wherein the bridging contact is in engagement with the stationary contact. A latching mechanism which is responsive to a bimetal or magnetic trip to allow the circuit breaker to trip open during overload conditions, holds the elongated contact arm in the closed position.

摘要： 514,716. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 14, 1938, No. 14448. Convention date, May 15, 1937. [Class 38 (v)] A switch for timing the energization of an X- ray tube 11 comprises a synchronous motor 18 which drives through worm gearing a wheel 20 loose on a shaft 21 to which it can be clutched by means of a pin 22 engaging holes 23 in wheel 20. The pin 22 is carried on a plate 24 slidably splined on shaft 21 and movable by means of a fork 26 against the action of a spring 25 by a solenoid 27. The shaft 21 carries adjustable cams 28, 29 which engage rollers 31 on contact arms 15, 17 biassed towards engagement with a fixed contact 16. The cams 28, 29 are adjusted so that contact arms 15, 17 are operated in succession and that they both engage the contact 16 for one fifteenth of a second which is the unit of time for this apparatus and is the time for one of the holes 23 to rotate into the position of the next hole. Also driven by motor 18 through a clutch 46 controlled by a solenoid 49 and reduction gearing 42, 45, is an arm 50 which is normally held by a spring 55 against a stop pin 51 but which, when clutch 46 is engaged, moves clockwise to cause a pin 54 to close contacts 36 and later contacts 37 which are adjustably mounted on an arm 52. Arm 52 may be set by a pointer 53 co-operating with a scale 51a marked in fifteenths of a second to show the time during which the circuit is closed. Starting from the position shown, with the motor 18 running and wheel 20 idling, and pointer 53 set to a desired time interval, switch 40 is depressed on to contact 38 to energize solenoid 49 to cause arm 50 to close contacts 36. This energizes solenoid 27 through contacts 34 and shaft 21 starts to rotate until circuit is closed at 15, 16, 17 and the tube 11 is energized. Cam 33 on shaft 21 then opens the circuit of solenoid 27 at 34 and closes contacts 35 and shaft 21 remains stationary until pin 54 closes contacts 37. This again energizes solenoid 27 through contacts 35 and shaft 21 rotates to break circuit at 15, 16, 17 and completes one revolution until circuit of solenoid 27 is opened at 35 by cam 33. When switch 40 is released, clutch 46 is de-energized and arm 50 returns under the action of spring 55. The time during which the circuit is closed is thus the time due to the different settings of cams 28, 29 plus the time during which the shaft 21 is stationary, that is the time taken for arm 50 to travel from the opening of contacts 36 to the closure of contacts 37 and is shown on dial 15a. The timing is exact since it depends on the number of holes 23 which pass pin 22 between the two energizations of solenoid 27.

摘要： processo e dispositivo para a desconexão de um comutador. em um processo para a separação de um contato de comutação de um contracontato em um comutador que conecta corrente alternada, com um ângulo de fase de cerca de 13º antes de uma próxima ou subsequente passagem zero da corrente é fornecido um pulso mecânico curto ao comutador com direção de pulso para a separação dos contatos. para isso é previsto um piezo-atuador no contracontato. este também pode medir uma força de contato presente, de tal modo que o pulso, além do ângulo de fase mencionado, só é ativado no caso de uma força de contato muito pequena que tenda a zero.

摘要： 592858 Disclosed is a method for adaptive three-phase fast reclosing applied to shunt compensated transmission lines. A relay is calibrated to a factory setting default reclosing time adjusted to a high value, and the reclosing time is automatically reset to the high value after line opening. The voltage across the contacts of the switching device is measured via potential transformers and an envelope of the voltage across the circuit breaker contacts is measured. The envelope signal is then filtered to eliminate high harmonics. A circuit breaker opening instant, a first half-cycle of the filtered signal and a half-cycle semi-period of the filtered signal are then all identified. A beat period is determined after dead time and the circuit breaker reclosing time is adjusted, setting it equal to the beat period after dead time.

摘要： In a method for disconnecting a switching contact from a mating contact in a switch which switches alternating current, a short mechanical pulse is applied to the switch with a pulse direction for disconnecting the contacts with a phase angle of approximately 13° before a next or a following zero crossing of the current. To this end, a piezoactuator is provided on the mating contact. Said piezoactuator can also measure the applied contact force, so that the pulse is triggered, in addition to said phase angle, only at a very low contact force which tends towards zero.
