Definitions

  • the invention relates to a circuit breaker pole for subsea application wherein the pole contains a vacuum interrupter and a drive mechanism, according to the preamble of claim 1.
  • Circuit breaker poles for subsea application means high pressure of about 300 bar outside and about one bar inside the pole.
  • the gases can be for example water vapor which might be dissolved the oil or other gases produced by decomposition products of the oil.
  • the reliability of the pole can be improved significant.
  • Core of the invention therefore is, that the hollow cylinder of insulating material, or the hollow cylinders of insulating material is or are made of pressure proof ceramics or porcelain, which is or are at the end surfaces metalized to allow soldering, in such, that the complete pole is assembled by soldering.
  • all externally connectable electrical connectors to the vacuum interrupter and the drive mechanism are embodied as conductive rings, which are soldered between at least two hollow cylinders of insulating material, or between one conductive part of the pole and one hollow insulating cylinder.
  • alternating serially arranged insulating and conductive cylinders can build up a structure, where the external terminals can be embodied by simple conductive rings, solded between two serially arranged insulating cylinders, or between one insulating cylinder and one conductive cylinder or a metallic end cap.
  • the several hollow insulating cylinders are arranged in series as such, that the conductive rings in the pole are located close to the place, where the terminals of the vacuum interrupter inside the pole is placed, so that the terminals of a fixed contact and the terminal of a moving contact of the vacuum interrupter can be directly connected to the conductive rings.
  • the connectors for the drive mechanism are embodied as a cylindrical multilayered structure of alternating layers of conductive and insulating rings.
  • pole housing consists of three different elements:
  • the cylinders might have contact areas for the external and/or internal connection with the current path.
  • This can be connection lugs.
  • Other means as threads for direct connection, especially at the primary contact are possible.
  • connection of the moving contact can be done in several ways: using a flexible copper between the moving contact and the primary conductor for the moving contact or it can be a contact spring or multicontacts between two conductive tubes, one connected with the moving contact, the other with the primary conductor for the moving contact or even being part of it.
  • an alternative solution can be to build the first half of the pole directly of a pressure proof vacuum interrupter, not requiring an additional housing. The second half would then covering drive mechanism.
  • Figure 1 shows a structure of alternating conductive and insulating cylinders and rings. Both end caps can be made of steel or porcelain. The contact rings are soldered between two parts each. In the right part of figure 1 , there is arranged a multilayered arrangement of alternating conductive and insulating rings, in order to result a multicontacting for signal wires for the drive. Inside the displayed pole, a vacuum interrupter and an drive mechanism is arrangend pressure tight by the enclosure, resulted by the pole.
  • Figure 2 shows the inner locations of the vacuum interrupter and the drive mechanism. Like it is shown, the terminals of the vacuum interrupter are locatd as such, that they are near to the conductive rings, soldered in the pole, in order to contact the terminals of the vacuum interrupter 30 with the external connections via the soldered conductive rings. According to the location of the drive 31, the aforesaid multilayered insulating and conductive rings are connected to the signal wires of the drive.
  • Figure 3 shows how the pole concerning to the invention will be assembled until before the vacuum interrupter and the drive will be arranged inside the pole, and the remaing only soldering line between the two parts of the pole will be closed by soldering finally.
