Definitions

  • the invention comprises a gear box and electric motor drive system which will typically be employed in an actuator for a rotary air break switch or other typically pole-top or near pole-top mounted circuit breaker in a power distribution network, but which may also have other applications.
  • air break switches or other circuit breakers are typically mounted at or near the pole-top and include an actuation mechanism such as a lever in a simplest form, operable from closer to ground level by a linesman or maintenance worker to actuate the air break switch.
  • the actuation lever is connected by a shaft or similar up the pole to the mechanical air break switch at the pole top.
  • the air break switch may be operated by the linesman or maintenance worker to open to break the circuit or line, and to close the air break switch to reconnect power after maintenance or fault finding has been finished.
  • the invention provides an electric motor and gear box drive assembly which is operable to provide output drive from the gear box either by operation of the electric motor or manually.
  • the invention also provides an actuator for a circuit breaker such as a pole-top or near pole-top air break switch, which enables the circuit breaker to be actuated either electrically, by a control signal over a radio link to a radio receiver and controller associated with the actuator, or manually by a linesman or maintenance worker at the pole.
  • the invention comprises an electric motor and gear box drive assembly which is operable to provide output drive from the gear box either by operation of the electric motor or manually, including an electric motor and a gear box movably mounted relative to one another such that the motor drive is in one relative position between the motor and the gear box connected through the gear box to an output drive from the gear box, and is in another relative position between the motor and the gear box disconnected through the gear box, and a manual drive shaft to the gear box which can be manually rotated to provide output drive from the gear box at least when the motor is disconnected from the output shaft from the gear box.
  • the invention comprises an actuator for a circuit breaker at or near a pole top, including an electric motor and gear box drive assembly which is operable to provide output drive from the gear box to a circuit breaker either by operation of the electric motor or manually, including an electric motor and a step-down gear box movably mounted relative to one another such that the motor drive is in one relative position between the motor and the gear box connected through the gear box to an output drive from the gear box, and is in another relative position between the motor and the gear box disconnected through the gear box, and a manual drive shaft to the gear box which can be manually rotated to provide output drive from the gear box at least when the motor is disconnected from the output shaft from the gear box, without back driving the electric motor.
  • the actuator includes a lever mechanism associated with the electric motor and gear box and which is operable to move the motor relative to the gear box.
  • the gear box and motor will be mounted in a cabinet positioned near the base of the pole and the output drive shaft from the gear box will be connected via a shaft or other mechanical means extending up the pole to the circuit breaker.
  • a radio receiver and motor control electronics may be housed within the cabinet along with optionally a battery power supply.
  • the circuit breaker may be actuated via a remote radio signal.
  • Figure 1 shows a preferred form of actuator for a circuit breaker such as a pole-top air break switch (not shown),
  • Figure 2 schematically illustrates the operation of the two position lever for moving the motor to disconnect or reconnect the motor drive
  • Figure 3 schematically shows the gear box and motor and the arrangement of gears within the gear box of the preferred form system.
  • gear box and electric motor drive assembly are shown as part of an actuator for a pole top air break switch.
  • a gear box 1 and motor 2 are mounted within a cabinet 3 which is fixed to a pole 4.
  • the air break switch is mounted at or near the pole top (not shown) and drive from the actuator within the cabinet 3 to the pole top to open and close the air break switch is via shaft 6 to which the output shaft 7 of the gear box is connected.
  • the motor 2 may be connected to the gear box 1 through a subsidiary step down gear box 10.
  • a radio receiver and motor controller board 8 (not shown in detail) are mounted within the cabinet 3, along with a battery 9.
  • a radio signal may be sent from afar to energise the motor 2 and the motor drive is connected through the gear box 1 to the shaft 6 to operate the pole top air break switch to open or close the air break switch.
  • the air break switch may be actuated manually by a linesman at the pole by unlocking and opening the cabinet door 5 and fitting a crank handle 11 to a manual drive shaft on the front face of the gear box 1, and rotating the crank handle to manually drive the shaft 6 and actuate the air break switch.
  • the manual crank handle 11 is stored within the cabinet 3, for example is held by spring clips or similar on the interior of the cabinet door 5 as shown in phantom outlined in Figure 1.
  • subsidiary gear box 10 will provide a step down ratio of the order of 50: 1 so that it would not be possible or would be very difficult to otherwise manually operate the actuator with the motor connected.
  • gear box 1 is fixedly mounted within the cabinet 3.
  • Lever 20 may be moved between two positions as indicated by arrow B in Figure 2.
  • Lever 20 is pivotally mounted and is also fixed via shaft 21 to the gear box or the cabinet, and is connected to the motor 2 or subsidiary gear box 10, so that when the lever is moved from one position to another this will slidably move the motor 2 (and subsidiary gear box 10).
  • the motor drive In one position of the lever the motor drive is connected into the gear box 1 while in another position of the lever the motor is moved to the position shown in broken lines in Figure 3, to disconnect the motor drive from the gear box, and in particular to disengage the gears 13 and 14.
  • the actuator is operated manually by rotating the manual drive shaft 17 via crank handle 10, the motor will not be back driven.
  • radio signal is intended to also include use of the cellular telephone or paging network for example, in which event the radio receiver will comprise or include a cell phone or pager unit.
  • a linesman at the pole may manually actuate the circuit breaker by opening the cabinet, operating the lever 20 to move the motor 2 (and subsidiary gear box 10) to disengage the motor drive from the gear box, and fitting the crank handle 11 to the manual drive shaft and rotating the handle to manually open or close the circuit breaker.
  • the linesman will open the circuit breaker for maintenance or fault finding, and subsequently close the circuit breaker, replace the crank handle, and re-lock the cabinet.
  • gear 18 may engage gear 14 instead of gear 16.
  • lever mechanism 20 moves the electric motor 2 (and subsidiary- gear box 10) relative to the gear box 1 but is as alternatively possible that the lever mechanism may move the gear box 1 relative to the electric motor 2, or both of the electric motor 2 and gear box 1 relative to one another.

Abstract

La présente invention concerne un actionneur pour un coupe-circuit monté en sommet de poteau ou à proximité de ce sommet. Cet actionneur se compose d'un moteur électrique et d'un ensemble moteur à boîte de vitesse. Il a pour fonction d'entraîner en sortie de boîte un coupe-circuit, soit du fait du fonctionnement du moteur électrique, soit du fait d'une manoeuvre manuelle. En l'occurrence, le moteur électrique et la boîte de vitesse réductrice sont mobiles l'un par rapport. Dans une première position du moteur par rapport à la boîte, celle-ci est en prise, alors que dans une seconde position du moteur par rapport à la boîte, celle ci est n'est plus en prise sur le moteur. Dans ce cas, un arbre d'entraînement manuel menant la boîte de vitesse, peut être tourné manuellement sans action en retour sur le moteur électrique.
