Definitions

  • High-voltage electrical cut-off devices are well known, filled with a gaseous dielectric fluid, most often sulfur hexafluoride (SF 6 ). These devices are large and their transport requires that they be made of several elements. These elements are assembled at the place of their use. These devices are filled with pressurized gas instead of their manufacture. Technical reasons require that the disassembly for transport or maintenance of the various components of the devices can be done without the gas contained in each element can not escape.
  • SF 6 sulfur hexafluoride
  • An object of the invention is to provide a pressurized gas circuit breaker, consisting of several elements, which can be assembled and disassembled, in which the transmission of movement to the movable contacts is ensured by a connecting rod-crank system, and which allows assembly and disassembly of the elements without loss of dielectric gas or appreciable introduction of outside air.
  • the subject of the invention is a pressurized gas circuit breaker which can be assembled and disassembled without loss of gas, comprising for each pole, a first enclosure and a second enclosure filled with pressurized gas, said first enclosure comprising a first envelope, a base and a top, and containing fixed contacts and a movable assembly comprising contacts cooperating with said fixed contacts, the movable assembly being movable by means of a rod, said base having an axial opening for the passage of the rod, said second enclosure comprising a second envelope resting on a casing and containing a connecting rod articulated to a crank pivoting around a shaft passing through the casing and connected outside of the latter to a means of rotation, said second enclosure being surmounted by a tubular spacer, said first and second enclosures being, when the circuit breaker is mounted, superimposed coaxially and fixed together, the connecting rod and the rod being secured by one of their ends, the mobile assembly then having an operating stroke between a first position where the circuit breaker is open and a second position where the circuit
  • FIG. 1 a three-pole circuit breaker 1, 2 and 3 is shown, controlled simultaneously by a hydraulic cylinder 4 comprising a piston 5 and a piston rod 6.
  • the three poles are identical and we will describe in detail the pole 2, shown in axial section in Figure 1.
  • poles 1 and 3 are operated from the shaft 41 by cranks 43, 44, 45, 46 and connecting rods 47, 48.
  • the two elements 2A and 2B are filled with gas under pressure during manufacture.
  • the hydraulic cylinder can be replaced by a spring-loaded control mechanism.
  • the invention is based on the following observations.
  • the normal travel x of the circuit breaker ( Figure 2) defines a low position of the crank (point 0) for which the circuit breaker is open, and a high position (point F) for which the circuit breaker is closed.
  • the relative travel of the fixed and mobile contacts of the breaking chamber allows this overtravel to be authorized, for current type circuit breakers. If this is not the case, provision will be made to extend the contact area between the fixed and mobile contacts.
  • the enclosure 2A is therefore leaktight thanks to the airlock 50 cooperating in leaktight manner by the seal 53 on the cylinder 16 and by the seal 54 bearing on the enlarged portion 12C of the rod 12.
  • the enclosure 2B is sealed by virtue of the head 30A which comes to seal the passage 29A by its seal 30C.
  • the overtravel position of the rod 30 is made fixed by immobilizing the crank 43 on the base 28 by a cleat 28A (fig. 2).
  • the enclosure 2A is freed from the axis 57 and brought above the enclosure 2B (FIG. 2), the head 12A penetrating into the chimney 31.
  • the seal is ensured by O-rings 61 and 61 ′ separated by a leak recovery channel 62 (fig. 5).
  • crank 43 is then released by displacement of the cleat 28A and the actuator is maneuvered to remove the overtravel dx.
  • the seal 54 of the head 52 of the airlock 50 is then in front of a small diameter portion of the rod 12, which breaks the previous seal. Similarly, the head 30A of the connecting rod 30 clears the passage 29A.
  • the gas communication between the enclosures 2A and 2B is also ensured by the orifices 34 of the spacer 31, and by at least one conduit such as 65, formed in the piston 17 and opening, when the circuit breaker is in the closed position, at level of a hole 66 in the blowing cylinder.
  • the only volume of air introduced into the enclosures during the assembly operation is that of interior volumes added to the chimney 31 and the airlock 50 which are very small compared to the total volume of gas in the appliance.
  • the disassembly of the device is done by performing the same operations in reverse.
  • the loss of dielectric gas upon disassembly is negligible.
