Definitions

  • the invention relates to a neutral conductor disconnecting device which is mechanically coupled to an interrupter device for phase contacts, consisting of an elastically bendable contact spring connecting two connecting terminals, which is permanently mounted on one of the two connecting terminals and can be switched to the second connecting terminal by means of an actuating device in which a manual actuator is formed on an approximately cylindrical bearing body rotatably mounted about a bearing journal.
  • An interruption or switching on of a neutral conductor by means of such a separation device should always take place manually. It must be ensured, however, that the neutral conductor disconnecting device is first switched on before the interrupter device for phase contacts. During the switch-off process, it must be prevented that the neutral disconnecting device is switched in front of the interrupter device for phase contacts.
  • the internal structure of the neutral separator should be simple and consist of a few parts.
  • the invention has for its object to develop a neutral disconnecting device of the type described in such a way that when a contact spring and an actuating device are used when closing the contacts it does not require a coil spring which is susceptible to faults.
  • the contact spring is separated from the second connection terminal in the force-free state and is connected to the actuating device by a bracket which, on the one hand, engages approximately in the middle of the contact spring and, on the other hand, is connected to the bearing body, the connection point in the switched-on position is formed above the bearing pin to form a toggle lever.
  • the bracket achieves a good frictional connection between the actuator and the contact spring, so that it can be brought against the spring force to the terminal.
  • the toggle lever is used for locking and prevents the contact spring from sliding back.
  • the contacts are welded, they can be opened powerfully using the bracket. Since no additional spring is required, there is no need to compensate for its spring force, so that the neutral conductor separating device works in a force-saving manner.
  • the contact spring is so elastic that its restoring force in the off position is greater than the frictional force of the actuating device. After opening the toggle lever, the contact spring is automatically disconnected from the terminal block automatically due to its spring tension without the influence of external forces.
  • the firmly locked end of the contact spring can be welded to one of the terminals in a manner known per se.
  • the free end of the contact spring can be covered with contact material, which largely prevents welding to the connection terminal.
  • the actuating device of the neutral conductor separating device can essentially be designed as a cylindrical disk with a radially attached handle arm as an actuating member. The center of the cylindrical disc is then supported on a journal. It can be rotated through an angle between its end positions, the geometry of the housing of the neutral Separating device limits the movement of the handle arm. This makes it possible to connect the contact spring to the actuating device in the form of a toggle lever by means of a bracket.
  • bracket For a simple construction, it is favorable to design the bracket in a U-shape. Its legs can be engaged with a hole in the cylindrical disk of the actuator and with an eyelet in the middle of the contact spring.
  • the bore in the cylindrical disc is to be designed so that it is perpendicular to the axis of rotation of the actuating device when the handle arm is in the switch-on position at the attachment point. This results in a simple construction of a toggle lever.
  • the mechanical coupling of the neutral disconnecting device with an interrupter device for phase contacts can be achieved in that the manual actuating member of the neutral separating device engages over the roof actuating member of the interrupting device for phase contacts in the switched-off position and has a protruding design. If this projection extends essentially up to the housing of the neutral conductor separating device, it is ensured that the manual operating element of the neutral conductor separating device is always switched on before the manual operating element of the interrupter device for phase contacts. Except for the roof-shaped extension of the manual actuator and its Such a coupling is known in a special mode of action in the case of mechanically connected line circuit breakers and residual current circuit breakers (DE-AS 12 80 382).
  • the manual actuators of the neutral conductor disconnecting device and the interrupter device for phase contacts can also be rigidly coupled, in which case the switch-on angle of the actuating member of the neutral conductor separating device is to be selected to be smaller than the switch-on angle of the actuating member of the interrupting device for phase contacts. Also in this manner ensures that the neutral separator always be in front of the shut-off mechanism for phase contacts - is on.
  • Another version for coupling the actuating devices of the neutral conductor disconnecting device and the interrupter device for phase contacts works with a push button. It has a pin which is connected to the interrupter device for phase contacts and which engages with an elongated hole formed in an angle in the bearing body of the neutral conductor separating device.
  • the push button makes it possible to switch off the neutral conductor disconnecting device and also the interrupter device for phase contacts manually more quickly than by means of a manual control element.
  • An actuating device consists of a manual actuating member 5, which is formed on a bearing body 6. This cylindrical bearing body 6 is arranged to be rotatable about a bearing pin 7 by a fixed angle. A bracket 8 starts from a bore 9 in the bearing body 6 and ends in an eyelet 10 at the center of the contact spring 4. When the contact Spring 4 abuts the terminal 3, the bore 9 is in the bearing body 6 above the bearing pin 7. Bracket 8 and bearing body 6 form a toggle lever, which can firmly lock the contact spring 4 on the terminal 3.
  • Fig. 2 shows a partial view of the housing 11 of an interrupter device for phase contacts with the manual actuator 12 in the off position.
  • the manual operating element 5 of the neutral conductor separating device is designed such that it engages over the manual operating element 12 of the interrupter device in a roof-shaped and projecting manner.
  • the projection 13 extends as far as the housing 11. Therefore, the manual control element 5 of the neutral disconnecting device can only be switched on in front of the manual control element 12 of the interrupter device, as is necessary for safety reasons.
  • FIG. 3 shows the bracket 8 of the neutral conductor separating device according to FIG. 1 alone. In its upper part, it has a lateral bend 14 to bypass the bearing journal 7.
  • Fig. 4 shows the bracket 8 of FIG. 3 in side view.
  • the leg 15 of the U-shaped bracket 8 is connected to the connection point 9 in the bearing body 6, e.g. a bore in the bearing body 6 according to FIG. 1 in engagement.
  • the leg 16 is mounted in the eyelet 10 at the center of the contact spring 4 according to FIG. 1.
  • FIG. 5 illustrates another embodiment of the neutral conductor separation device according to FIG. 1. It is connected to a breaker device for phase contacts via a pin 17. This pin 17 is in engagement with an elongated hole 18 formed over an angle in the bearing body 19 of the neutral conductor separating device. A coupling lug 20 is on the bearing body 19 trained, on which a push button 21 can exert a force. The remaining structure corresponds to that of FIG. 1.
  • the pin 17 moves in the slot 18 along.
  • the bearing body 19 takes the pin 17 with it and thus also switches off the interrupter device for phase contacts.
  • a push button 21 is provided, which is arranged above a coupling lug 20 formed on the bearing body 19. After actuation of the push button 21, the toggle lever is released from the bracket 8 and the bearing body 19, so that the contact spring 4 can relax and the neutral conductor separating device opens.
  • the interrupter device for phase contacts is switched on manually, the pin 17 is also moved.
  • the neutral conductor separating device is previously switched off, the pin 17 engaging in the elongated hole 18 takes the bearing body 19 with it, rotates it and closes the toggle lever and thus the contact spring 4.
